Confuse about addEventListener to objects

vitalitymobile · June 2012

Hi all,
I just want to implement simple addEventListener to check what object is clicked:

	local function onTouch(self,event)
		print(self.col)
	end
 
	local token_orange_list = {};
	for i=1,7 do
		token_orange_list[i] = Bitmap.new(Texture.new("image.png"));
		print(token_orange)
		token_orange_list[i]:setAnchorPoint(0.5, 0.5)
		token_orange_list[i]:setPosition(startX +(i-1)*delta ,startY);
		token_orange_list[i]:setScale(0.8,0.8)
		token_orange_list[i].col = i;
		token_orange_list[i]:addEventListener(Event.MOUSE_DOWN, onTouch,token_orange_list[i])		
		firstRowLayer_Orange:addChild(token_orange_list[i])
	end

But when i click to an object, it print out all 7 value (from 7 down to 1)
So can you tell me how to do this?
Thanks!

Hi,

have you tried Event:stopPropagation()?
You can check the "Drag Me" example to see it in action.

Thanks @Mells,
Just change onTouch to:

	local function onTouch(self, event)
		if self:hitTestPoint(event.x, event.y) then
			print(self.col)
			event:stopPropagation()
		end
	end

And it works!
Thanks for your comment :P
