Timer iOS cycle implementation

helloworld2013d · May 8, 2015, 6:02pm

Hi Everyone…

I am trying to do a simple task, but I got stuck on the third step.

I have 3 objects; obj1, obj2, obj3

I am adding an Event Listener to all 3

I have only the 1st one Visible --> obj1.isVisible = true

I touch obj1 … obj1.isVisible = false … obj1 gives me 1 point

I see NO objects…

…after 20 seconds I can see obj2 --> obj2.isVisible = true

Now I have only the 2nd one Visible --> obj2.isVisible = true

I touch obj2 … obj2.isVisible = false … obj2 gives me 1 point … now I have 2 points

now I see NO objects…

…after 20 seconds I can see obj3 --> obj3.isVisible = true

Now I have only the 3nd one Visible --> obj3.isVisible = true

I touch obj3 … obj3.isVisible = false … obj3 gives me 1 point … now I have 3 points

now I see NO objects…

PROBLEM…

I am expecting that after 20 seconds I can see obj1 visible again…

but nothing happens I don’t see the object 1 after 20 hours…

I am just trying to make a loop on those three objects, like after obj3

shows obj1, star ll over again, like that.

I hope this make sense and somebody can get me an idea in how to do this.

If you want I can post my code…

Thanks for all your help and all your time

How about creating a table of objects, and iterating over it in your timer function. Something like:

--Create a table to hold all the objects local objs={} --Create objects and add them to table local objs[1] = display.newRect(...) local objs[2] = display.newRect(...) local objs[3] = display.newRect(...) --Make objects 2 and 3 invisible objs[2].isVisible=false objs[3].isVisible=false --Counter to indicate which object is currently visible local visibleObject=1 --Timer function. Makes the current object invisible, and the next object visible. local function updateObject() &nbsp; --Make the current object invisible &nbsp; &nbsp;objs[visibleObject].isVisible=false &nbsp; &nbsp;--Bump the visible object counter &nbsp; &nbsp;visibleObject=visibleObject+1 --Don't overflow &nbsp; &nbsp;if (visibleObject==4) then visibleObject=1 end --Make the next object visible &nbsp; &nbsp;objs[visibleObject].isVisible=true end --Call the timer function every 1s forever timer.performWithDelay(1000, updateObject, -1)

When I run your code…

I see circle 1 … then after the timer,

1 is gone!! I see 2 … after the timer

2 is gone!! I see 3 … after the timer

3 is gone!! I see 1 …

Works GREAT!!!

but in my code when I touch object 1 with no timer

the object is waiting for me to touch it…

1 is fine

2 is fine

3 PROBLEMS!!!..

Why I can not pass the last object?

This is my function

&nbsp;&nbsp;&nbsp; --Create a table to hold all the objects &nbsp;&nbsp; &nbsp;local objs={} &nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp; function objsListener( event ) &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if event.phase == "began" then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if ( event.target.id ) == 1 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("1") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- obj 1 is gone! &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[1].isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Bump the visible object counter &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;visibleObject=visibleObject+1 &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the current object invisible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=false &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Don't overflow &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if (visibleObject==4) then visibleObject=1 end &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the next object visible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=true &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif ( event.target.id ) == 2 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("2") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- obj 2 is gone! &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[2].isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Bump the visible object counter &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;visibleObject=visibleObject+1 &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the current object invisible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=false &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Don't overflow &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if (visibleObject==4) then visibleObject=1 end &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the next object visible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=true &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif ( event.target.id ) == 3 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("3") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- obj 3 is gone! &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[3].isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Bump the visible object counter &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;visibleObject=visibleObject+1 &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the current object invisible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=false &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Don't overflow &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if (visibleObject==4) then visibleObject=1 end &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the next object visible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=true &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return true&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp;&nbsp; end

What is wrong?

I think you’ll throw an error when you get to the third object, because:

you reach the line - elseif ( event.target.id ) == 3 then
then you make the third object invisible
then you bump the object counter (which will then equal 4)
then you try to make the fourth object invisible…
… but there isn’t a fourth object - so an error will be thrown, and the function is stopped prematurely (meaning the rest of the function is never executed)

helloworld2013d · May 8, 2015, 10:20pm

Good, now it works fine…thanks. with a simple 3 dots.

Now when I try that in MY real code, actually using the waiting time…

PROBLEMS!!! This is giving me headaches…

Sorry the code is long but please help me out.

The Last function is the one we are working on

just scrol down to the end…

(I put all of them just in case)

I have a normal function to add score or life

&nbsp;&nbsp;&nbsp; function addToLife() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;lifeTxt.isVisible = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;life = archivo.datos.life &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;life = life + 1 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;archivo.datos.life&nbsp; = life &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;archivo:guarda() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;lifeTxt.text = life &nbsp;&nbsp; &nbsp;end

Now the function to waiting period…

&nbsp;&nbsp;&nbsp; function collectLife() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local lifeDuration = os.time() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local function waitingLife() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local nowGetLife = os.time() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if ( nowGetLife \> lifeDuration + 5 ) then &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;cofre[visibleObject].isVisible = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;lifeTimer = timer.performWithDelay(20000, waitingLife) &nbsp;&nbsp; &nbsp;end

then a little function to tell me that the little diamon (diamantito) got to his place

&nbsp;&nbsp;&nbsp; function yaLlego() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;diamantito.isVisible = false &nbsp;&nbsp; &nbsp;end

Now for the diamond to move to the center of the screen

&nbsp;&nbsp;&nbsp; function juntaVidita() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(diamantito, { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=10, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;x = display.contentCenterX + 2000, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;y = display.contentCenterY - 1020, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = .3, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = .3, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;rotation = 0, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;alpha = 0, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;onComplete = yaLlego &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;end

this is to make the objects dissapear – cofre is the object

function vidita() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;diamantito.alpha = 1 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;diamantito.isVisible = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(diamantito, { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=1500, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;x = display.contentCenterX, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;y = display.contentCenterY, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = 2, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = 2, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;rotation = 130, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition = easing.inSine, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--alpha = 0, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;onComplete = juntaVidita &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if (viditaRound == 1) then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(cofre[1], { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=200, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;alpha = 0 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;viditaRound = 2 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif (viditaRound == 2) then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(cofre[2], { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=200, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;alpha = 0 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;viditaRound = 3 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif (viditaRound == 3) then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(cofre[3], { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=200, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;alpha = 0 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;viditaRound = 4 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;else &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;addToLife() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;collectLife() &nbsp;&nbsp; &nbsp;end

And finally here is the function that will make the magic…

function cofreListener( event ) &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if event.phase == "began" then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if ( event.target.id ) == 1 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- obj 1 is gone!

Sorry I have no other way to do this… I guess it should be an easier way

or faster or better, but this is all I know…

Thanks a lot for your help

Hi Victor,

Sometimes when you’re figuring this stuff help, it can help to grab a scrap piece of paper and manually execute the code on the page. ie. draw three ‘objects’ on the page, and write ‘isVisible’ in each. Also add a separate variable for ‘visibleObject’ somewhere on the page. Jot next to each variable what its initial value is. Now execute the program by hand, slowly following the steps the computer will take, crossing out and writing new variable values on the page as you go. It’ll help you see where there are any errors in the logic.

I think, in your loop, your getting some of the isVisible settings out of sequence.

In your cofreListener function, for each object you need to:

make the current object invisible
bump the counter (and wrap if necessary)
make the next object visible

In your code, this is out of sequence. What your code does is:

make the current object invisible (fine)
bump the counter (fine)
make the next object invisible - if the counter currently exceeds the table limit, you’ll be trying to make a non-object (or nil object) invisible, causing an error to be thrown and execution will halt
wrap counter if necessary (too late - may never be reached)

You can also save a lot of code by using event.target.id to your advantage. Rather than hard coding event.target==“1”, event.target==“2”. Your cofreListener function would look something like this:

if event.phase == "began" then --Get the object (based on the target ID, rather than hard coding to 1,2,3) local obj = cofre[event.target.id] --Make it disappear obj.isVisible=false --Bump counter visibleObject = visibleObject+1 --Now check for overflow, otherwise you may try to make a nil object visible / invisible if (visibleObject==4) then visibleObject=1 end --Get the next object to work on local next = cofre[visibleObject] --Make the next object visible next.isVisible=true --Don't know what this does, but use event.target.id so you don't have to hard code everything --These lines seem to relate to the next object diamantito.x = next.x diamantito.y = next.y --These lines seem to relate to the previous object plus1.x = obj.x plus1.y = obj.y --These lines seem to call function vidita when viditaRound is the same as event.target.id if (viditaRound == event.target.id) then &nbsp; &nbsp; vidita() end return true end

Hope that helps. Don’t guarantee this code will be perfectly as is - it’s just there as a demonstration.

You are helping me a lot… thanks…

I still don’t have it working the way I want…

I will put more time this weekend…

But the

--Get the object (based on the target ID, rather than hard coding to 1,2,3)
local obj = cofre[event.target.id]

Helped me a lot, I didn’t know this…

also the “paper” idea… I will do that, line by line thinking the logic I need

Thanks for all your help, I will let you know If I got it to work…

Cool - good luck

How about creating a table of objects, and iterating over it in your timer function. Something like:

--Create a table to hold all the objects local objs={} --Create objects and add them to table local objs[1] = display.newRect(...) local objs[2] = display.newRect(...) local objs[3] = display.newRect(...) --Make objects 2 and 3 invisible objs[2].isVisible=false objs[3].isVisible=false --Counter to indicate which object is currently visible local visibleObject=1 --Timer function. Makes the current object invisible, and the next object visible. local function updateObject() &nbsp; --Make the current object invisible &nbsp; &nbsp;objs[visibleObject].isVisible=false &nbsp; &nbsp;--Bump the visible object counter &nbsp; &nbsp;visibleObject=visibleObject+1 --Don't overflow &nbsp; &nbsp;if (visibleObject==4) then visibleObject=1 end --Make the next object visible &nbsp; &nbsp;objs[visibleObject].isVisible=true end --Call the timer function every 1s forever timer.performWithDelay(1000, updateObject, -1)

When I run your code…

I see circle 1 … then after the timer,

1 is gone!! I see 2 … after the timer

2 is gone!! I see 3 … after the timer

3 is gone!! I see 1 …

Works GREAT!!!

but in my code when I touch object 1 with no timer

the object is waiting for me to touch it…

1 is fine

2 is fine

3 PROBLEMS!!!..

Why I can not pass the last object?

This is my function

&nbsp;&nbsp;&nbsp; --Create a table to hold all the objects &nbsp;&nbsp; &nbsp;local objs={} &nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp; function objsListener( event ) &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if event.phase == "began" then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if ( event.target.id ) == 1 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("1") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- obj 1 is gone! &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[1].isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Bump the visible object counter &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;visibleObject=visibleObject+1 &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the current object invisible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=false &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Don't overflow &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if (visibleObject==4) then visibleObject=1 end &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the next object visible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=true &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif ( event.target.id ) == 2 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("2") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- obj 2 is gone! &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[2].isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Bump the visible object counter &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;visibleObject=visibleObject+1 &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the current object invisible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=false &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Don't overflow &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if (visibleObject==4) then visibleObject=1 end &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the next object visible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=true &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif ( event.target.id ) == 3 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("3") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- obj 3 is gone! &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[3].isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Bump the visible object counter &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;visibleObject=visibleObject+1 &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the current object invisible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=false &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Don't overflow &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if (visibleObject==4) then visibleObject=1 end &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--Make the next object visible &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;objs[visibleObject].isVisible=true &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return true&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp;&nbsp; end

What is wrong?

happymongoose · May 8, 2015, 9:44pm

I think you’ll throw an error when you get to the third object, because:

you reach the line - elseif ( event.target.id ) == 3 then
then you make the third object invisible
then you bump the object counter (which will then equal 4)
then you try to make the fourth object invisible…
… but there isn’t a fourth object - so an error will be thrown, and the function is stopped prematurely (meaning the rest of the function is never executed)

helloworld2013d · May 8, 2015, 10:20pm

Good, now it works fine…thanks. with a simple 3 dots.

Now when I try that in MY real code, actually using the waiting time…

PROBLEMS!!! This is giving me headaches…

Sorry the code is long but please help me out.

The Last function is the one we are working on

just scrol down to the end…

(I put all of them just in case)

I have a normal function to add score or life

&nbsp;&nbsp;&nbsp; function addToLife() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;lifeTxt.isVisible = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;life = archivo.datos.life &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;life = life + 1 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;archivo.datos.life&nbsp; = life &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;archivo:guarda() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;lifeTxt.text = life &nbsp;&nbsp; &nbsp;end

Now the function to waiting period…

&nbsp;&nbsp;&nbsp; function collectLife() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local lifeDuration = os.time() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local function waitingLife() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local nowGetLife = os.time() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if ( nowGetLife \> lifeDuration + 5 ) then &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;cofre[visibleObject].isVisible = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;lifeTimer = timer.performWithDelay(20000, waitingLife) &nbsp;&nbsp; &nbsp;end

then a little function to tell me that the little diamon (diamantito) got to his place

&nbsp;&nbsp;&nbsp; function yaLlego() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;diamantito.isVisible = false &nbsp;&nbsp; &nbsp;end

Now for the diamond to move to the center of the screen

&nbsp;&nbsp;&nbsp; function juntaVidita() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(diamantito, { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=10, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;x = display.contentCenterX + 2000, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;y = display.contentCenterY - 1020, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = .3, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = .3, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;rotation = 0, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;alpha = 0, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;onComplete = yaLlego &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;end

this is to make the objects dissapear – cofre is the object

function vidita() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;diamantito.alpha = 1 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;diamantito.isVisible = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(diamantito, { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=1500, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;x = display.contentCenterX, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;y = display.contentCenterY, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = 2, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = 2, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;rotation = 130, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition = easing.inSine, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;--alpha = 0, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;onComplete = juntaVidita &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if (viditaRound == 1) then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(cofre[1], { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=200, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;alpha = 0 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;viditaRound = 2 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif (viditaRound == 2) then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(cofre[2], { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=200, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;alpha = 0 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;viditaRound = 3 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif (viditaRound == 3) then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(cofre[3], { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;time=200, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;xScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yScale = 0.01, &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;alpha = 0 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;viditaRound = 4 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;else &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;addToLife() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;collectLife() &nbsp;&nbsp; &nbsp;end

And finally here is the function that will make the magic…

function cofreListener( event ) &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if event.phase == "began" then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if ( event.target.id ) == 1 then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-- obj 1 is gone!

or faster or better, but this is all I know…

Hi Victor,

Sometimes when you’re figuring this stuff help, it can help to grab a scrap piece of paper and manually execute the code on the page. ie. draw three ‘objects’ on the page, and write ‘isVisible’ in each. Also add a separate variable for ‘visibleObject’ somewhere on the page. Jot next to each variable what its initial value is. Now execute the program by hand, slowly following the steps the computer will take, crossing out and writing new variable values on the page as you go. It’ll help you see where there are any errors in the logic.

I think, in your loop, your getting some of the isVisible settings out of sequence.

In your cofreListener function, for each object you need to:

make the current object invisible
bump the counter (and wrap if necessary)
make the next object visible

In your code, this is out of sequence. What your code does is:

make the current object invisible (fine)
bump the counter (fine)
make the next object invisible - if the counter currently exceeds the table limit, you’ll be trying to make a non-object (or nil object) invisible, causing an error to be thrown and execution will halt
wrap counter if necessary (too late - may never be reached)

You can also save a lot of code by using event.target.id to your advantage. Rather than hard coding event.target==“1”, event.target==“2”. Your cofreListener function would look something like this:

if event.phase == "began" then --Get the object (based on the target ID, rather than hard coding to 1,2,3) local obj = cofre[event.target.id] --Make it disappear obj.isVisible=false --Bump counter visibleObject = visibleObject+1 --Now check for overflow, otherwise you may try to make a nil object visible / invisible if (visibleObject==4) then visibleObject=1 end --Get the next object to work on local next = cofre[visibleObject] --Make the next object visible next.isVisible=true --Don't know what this does, but use event.target.id so you don't have to hard code everything --These lines seem to relate to the next object diamantito.x = next.x diamantito.y = next.y --These lines seem to relate to the previous object plus1.x = obj.x plus1.y = obj.y --These lines seem to call function vidita when viditaRound is the same as event.target.id if (viditaRound == event.target.id) then &nbsp; &nbsp; vidita() end return true end

Hope that helps. Don’t guarantee this code will be perfectly as is - it’s just there as a demonstration.

helloworld2013d · May 11, 2015, 11:22pm

You are helping me a lot… thanks…

I still don’t have it working the way I want…

I will put more time this weekend…

But the

--Get the object (based on the target ID, rather than hard coding to 1,2,3)
local obj = cofre[event.target.id]

Helped me a lot, I didn’t know this…

also the “paper” idea… I will do that, line by line thinking the logic I need

Thanks for all your help, I will let you know If I got it to work…
