question on isVisible = true

helloworld2013d · October 4, 2013, 6:34pm

I’m trying to get an object “obj1” to show(isVisible = true) at the push of a button. (it’s a yellow rect)

using – timer.performWithDelay(1000, newListener ), a new rect “obj2” will show and “obj1” will hide.

then “obj3” at 2 seconds show and obj2 hide, just like that in a sequence.

– That’s easy I can do that so far.

I have a “stop” button, or “done” or “reset” button

so when people push that button “everything” must end or stop.

I have one function for each “obj”

local function yellow1 () &nbsp;&nbsp; &nbsp;local function obj11Listener( event ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; obj1.isVisible = true &nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;timer.performWithDelay( 200, obj1Listener ) end &nbsp; local function yellow2 ()&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;local function obj2Listener( event ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; obj1.isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; obj2.isVisible = true &nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;timer.performWithDelay(3130, obj2Listener ) end

like that.

in another function I call all of them at the same time

local function pennyTap () &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local function play () &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;audio.play(pennySong) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(pennyImageLarge, {time=200, x=display.contentWidth / 2, y=display.contentHeight / 2, xScale=1, yScale=1, alpha=1, onComplete=play}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(done, {time=200, y=700}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yellow1() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yellow2() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yellow3() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;yellow4() -- and so on &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end

in the done button I have this

local function doneStop () &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;audio.stop() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(done, {time=200, y=900}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(pennyImageLarge, {time=200, x=pennyImage.x, y=pennyImage.y, xScale=.1, yScale=.1, alpha=0}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; obj1.isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; obj2.isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; obj3.isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; obj4.isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end

even when all the objects are = false

because of the previews calls I keep seeing the rects show and hide

how can I solve this problem?

any suggestions on a new and better approach for this problem?

thanks for your help.

You should assign the timer calls to variables, then cancel them all in your done function. Keep in mind scope, so you’ll need forward references to the timer variables.

it make sense…

how do I do that?

I tried this – didn’t work

– local timer1 = timer.performWithDelay( 200, measure1Listener )

I don’t know how

I found this on line

it is what you just said and it works great!

exactly what I need it

local throwBrickTimer -- Reference for the timer function scene:enterScene(event) planeta.enterFrame = rotarPlaneta Runtime:addEventListener("enterFrame", planeta) Runtime:addEventListener("touch", touchScreen) --\> Give the timer a variable throwBrickTimer = timer.performWithDelay( 1000, throwBrickEnemigo,0 ) end function scene:exitScene(event) --\> Cancel the timer timer.cancel(throwBrickTimer) Runtime:removeEventListener("enterFrame", planeta) Runtime:removeEventListener("enterFrame", touchScreen) Runtime:removeEventListener("enterFrame", planeta) end

it feels so good to learn one more thing.

I probably know about 24 functions do do different things

I wonder how many there are?
