Movieclip class

Ninjadoodle

Hi guys

I have a movie clip class, which I would like to create in my scene and change it's frame on click.

LightSwitch = Core.class(Sprite)   function LightSwitch:init(x, y, container) local frames = {}   frames[1] = Bitmap.new(Texture.new("media/lightSwitch.png", true)) frames[2] = Bitmap.new(Texture.new("media/lightSwitchOn.png", true))   frames[1]:setAnchorPoint(0.5, 0.5) frames[2]:setAnchorPoint(0.5, 0.5)   local mc = MovieClip.new{ {1, 1, frames[1]}, {2, 2, frames[2]}, } mc.frame = 1   mc:setPosition(x, y) self:addChild(mc) container:addChild(self) end

I create it inside my scene like this ...

function Scene1:onTransitionInEnd() self.lightSwitch = LightSwitch.new(160, 160, layerMG) self.lightswitch:gotoAndStop(1) end

.... but I get an error when trying to make it goto frame 1

If anyone can help, that would be awesome!

Thank you in advance!

if you need to operate the movieclass inside your lightswitch later then you have to make it not local, e.g.
self.mc = MovieClip.new...
instead of local mc=...
and then you can do:
self.lightswitch.mc:gotoAndStop(1)

also you can add additional functions to your class which handle this by themselves so you don't deal with the mc directly.
e.g.

function LightSwitch:gotoAndStop(i) self.mc:gotoAndStop(i) end   self.lightSwitch:gotoAndStop(1)

will work. btw be careful about uppercase, you wrote self.lightswitch once and self.lightSwitch the other time, so that would crash even if you do as i said above.

note that a local value is reachable only inside that function and not inside any function of the same class. that's why self.. is needed.

Thanks heaps, that makes it a lot clearer
