    Classes & mouse events

    Hi guys

    I've been away for a while working with HTML5, but just came back to check out whats happening with Gideros. It's awesome to see it growing :)

    I have a quick question about mouse events when using 'classes'.

    I have a 'classes.lua' file with ...
    function createContainers(scene)
	layerBG = Sprite.new()
	layerMG = Sprite.new()
	layerFG = Sprite.new()
	scene:addChild(layerBG)
	scene:addChild(layerMG)
	scene:addChild(layerFG)
end
 
LightSwitch = Core.class(Sprite)
 
function LightSwitch:init(x, y, container)
    local sprite = Bitmap.new(Texture.new("media/lightSwitch.png", true))
	sprite:setAnchorPoint(0.5, 0.5)
	sprite:setPosition(x, y)
	container:addChild(sprite)
end
    Then I'm trying to create the switch in one of my levels.
    Scene1 = gideros.class(Sprite)
function Scene1:init()
 
require "classes"
createContainers(self)
 
lightSwitch = LightSwitch.new(160, 160, layerBG)
lightSwitch2 = LightSwitch.new(240, 160, layerBG)
 
local function lightSwitchTouch(button, event)
	if lightSwitch:hitTestPoint(event.x, event.y) then
		sceneManager:changeScene('scene2', 2, SceneManager.fade, easing.outBack)
		lightSwitch:removeEventListener(Event.MOUSE_UP, lightSwitchTouch, lightSwitch)
	end
end
 
lightSwitch:addEventListener(Event.MOUSE_UP, lightSwitchTouch, lightSwitch)
 
end
    The problem is, that it doesn't seem to be responding to any mouse/touch events.

    If anyone could help, that would be awesome :)

    Thanks in advance!

      It looks like your lightSwitch Sprite is never added to the stage itself, hence it cannot catch events.
      In your LightSwitch:init, you link the Bitmap sprite directly to the container, the LightSwitch is never made part of the scene. There are many things you can do:

      A) Make your LightSwitch object inherit from Bitmap and let it be the real switch visual (issue is that you can't change the constructor signature, it will have to match Bitmap constructor)

      B) Redefine LightSwitch:addEventListener so that it calls the inner sprite addEventListener()

      C) Add the inner Bitmap into the LightSwitch sprite, and add the LightSwitch sprite to the stage (probably the simplest way).
      function LightSwitch:init(x, y, container)
    local sprite = Bitmap.new(Texture.new("media/lightSwitch.png", true))
	sprite:setAnchorPoint(0.5, 0.5)
	sprite:setPosition(x, y)
        self:addChild(sprite)
	container:addChild(self)
end

      So, the above works perfectly :) Now however I'm struggling to do the same with a MovieClip.
      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))
 
	local mc = MovieClip.new{
		{1, 1, frames[1]}, 
		{2, 2, frames[2]}, 
	}
	mc:setPosition(x, y)
	self:addChild(mc)
	container:addChild(mc)
end
      Thanks again for any help :)

      Your last line should be:
      container:addChild(self)
      not
      container:addChild(mc)
