How to create an instance with its own ENTER_FRAME event

zehreken

Hi,
I want my object instances have their own ENTER_FRAME events but I couldn't manage to do it. Here is my test code.

Object.lua

Object = Core.class(Sprite) local tmp = 0 local function onEnterFrame() tmp = tmp + 1 print(tmp) end function Object:init() self:addEventListener(Event.ENTER_FRAME, onEnterFrame) end

Main.lua

for i=1,4 do local object = Object.new() end

I expect an output like this

0 0 0 0 1 1 1 1...

And this is what I get

0 1 2...

Only the first instance gives this output.

Dont forget to add third argument to :addEventListener

self:addEventListener(Event.ENTER_FRAME, self.onEnterFrame, self)

Nope, it doesn't make a difference.

Try this
Object.lua:

Object = Core.class(Sprite) local function onEnterFrame(this) this.tmp = this.tmp + 1 print(this.tmp) end   function Object:init() self:addEventListener(Event.ENTER_FRAME, onEnterFrame, self) self.tmp = 0 end

main.lua:

local instances = {}   for i=1,4 do instances[#instances+1] = Object:new() end

It works, thank you.

this works too :

Object = Core.class(Sprite) function Object:init() self.tmp = 0 self:addEventListener(Event.ENTER_FRAME, self.onEnterFrame, self) end function Object:onEnterFrame() self.tmp = self.tmp + 1 print(self.tmp) end

Maybe it would be more appropriate for some other cases than the Enter_frame event though.
I like the fact that onEnterFrame() is not accessible from "outside" in Scouser's example.
