Question on AddEventListener "Touch"

helloworld2013d · April 2, 2015, 7:53pm

Hi Everyone…

I have 1 image

&nbsp;&nbsp;&nbsp; bgOff = display.newImageRect( sceneGroup, "images/sBgOff.png", 430, 430 ) &nbsp;&nbsp;&nbsp; bgOff.x = display.contentCenterX - separacionX &nbsp;&nbsp;&nbsp; bgOff.y = display.contentCenterY &nbsp;&nbsp;&nbsp; bgOff:scale (.7, .7) &nbsp;&nbsp;&nbsp; bgOff.anchorX = 1 &nbsp;&nbsp;&nbsp; bgOff.anchorY = 1 &nbsp;&nbsp;&nbsp; bgOff.isVisible = true

I add 1 function “touch”

&nbsp;&nbsp;&nbsp; function bgOff:touch( event ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if event.phase == "began" then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;quitaFlechita() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;bgOn.isVisible = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;bgOff.isVisible = false &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;bringBgs() &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;bgOff:addEventListener( "touch", bgOff )

WORKS FINE!

the problem I have is when I want to use the “loop” – for i …

Like this I have 7 images in 1 loop, they work great

&nbsp;&nbsp;&nbsp; local numerito = 1 &nbsp;&nbsp;&nbsp; for i = 1, 7 do &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;nail[i] = display.newImageRect( sceneGroup, "images/nail" .. numerito .. ".png", 250, 188 ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;nail[i].x = - 100 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;nail[i].y = -30 + i\*120 &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;nail[i]:scale (.6, .6) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;nail[i].isVisible = true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;numerito = numerito + 1 &nbsp;&nbsp;&nbsp; end

Now… How do I add an event listener to all 7 of them, so I can do something different on each of them

I did this and it won’t work

&nbsp;&nbsp;&nbsp; function nail[i]:touch( event ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if event.phase == "began" then &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;transition.to(negrito, {time=100, x=100, y=nail[1].y}) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return true &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;end &nbsp;&nbsp; &nbsp;nail[i]:addEventListener( "touch", nail[i] )

even if I change … nail[i] for nail[1]

Please I need your help, thank you very much for everything you do to help me

and all of us in the forum, thanks.

It’s okay Rob, I am sorry.

My intention was not to rush anybody.

While I was working on the code, I was just checking the forum

and I thought it would be nice to keep track of how many views

before someone will answer…

I will wait

thanks

You could try something like… function doSomething ( event ) local obj = event.target if event.phase == “began” then If obj.name == 1 then ---- elseif obj.name == 2 then ---- continue for 7 conditions end return true end end local numerito = 1 for i = 1, 7 do nail[i] = display.newImageRect( sceneGroup, “images/nail” … numerito … “.png”, 250, 188 ) nail[i].name = i nail[i].x = - 100 nail[i].y = -30 + i*120 nail[i]:scale (.6, .6) nail[i].isVisible = true numerito = numerito + 1 nail[i]:addEventListener( “touch”, doSomething) end

One thing that is very confusing about your question is in each example you give you seem to be referring to different objects: bgOn, bgOff, nail, negrito.

(You didn’t get an answer because its hard to understand what you’re trying to do other than re-use the code for a touch listener.)

However, to make one object and re-use the same code for a touch listener do this ( note use of ‘self’ ):

local function touch( self, event ) if event.phase == "began" then self.isVisible = true return true end return false end local numerito = 1 for i = 1, 7 do nail[i] = display.newImageRect( sceneGroup, "images/nail" .. numerito .. ".png", 250, 188 ) nail[i].x = - 100 nail[i].y = -30 + i\*120 nail[i]:scale (.6, .6) nail[i].isVisible = true nail[i].touch = touch nail[i]:addEventListener("touch") numerito = numerito + 1 end

Hi “kilopop” and “roaminggamer” thanks for your answer…

I use a little bit of each to make this

local function touch( self, event ) &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;local obj = event.target &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if event.phase == "began" then &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;self.isVisible = true &nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;if obj.name == 1 then &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("el numero 1") &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif obj.name == 2 then &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("el numero 2") &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif obj.name == 3 then &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("el numero 3") &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif obj.name == 4 then &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("el numero 4") &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif obj.name == 5 then &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("el numero 5") &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;elseif obj.name == 6 then &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("el numero 6") &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;else &nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;print("el numero 7") &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;end &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;return false &nbsp;&nbsp; &nbsp;end local numerito = 1 for i = 1, 7 do &nbsp;&nbsp; nail[i] = display.newImageRect( sceneGroup, "images/nail" .. numerito .. ".png", 250, 188 ) &nbsp;&nbsp; nail[i].x = display.contentCenterX &nbsp;&nbsp; nail[i].y = display.contentCenterY + i\*120 &nbsp;&nbsp; nail[i]:scale (.6, .6) &nbsp;&nbsp; nail[i].isVisible = true &nbsp;&nbsp; nail[i].name = i &nbsp;&nbsp; nail[i].touch = touch &nbsp;&nbsp; nail[i]:addEventListener("touch") &nbsp;&nbsp; numerito = numerito + 1 end

I use the obj.name from top

and in the self, example I didn’t know how to detect each object

and in the example above I didn’t use the “self” inside the (event) function

is kind of confusing, but now it works the way I was expecting…

But just for me learning more… could you please explain a little bit more… thanks
