Classes & mouse events

Ninjadoodle

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)

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

Thank you! This helps a lot

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)

Oh my god! I don't know how I missed that

Thanks heaps! I think it's time to get away from the computer haha
