Cocos2d-html5 v2.0 to v2.1 - Uncaught TypeError: Object #<Class> has no method 'initWithColor' - cc.LayerColor

cocos2d-x JavaScript
#1

I searched around a bit, but couldn’t find anything for the sake of solution. How to solve this issue? Or is it a problem that I created?

I am trying to implement the tutorial here: [[http://www.gamefromscratch.com/post/2012/06/17/Cocos2D-HTML-Tutorial-4-It’s-all-about-control.aspx]]

var MyThirdApp = cc.LayerColor.extend(
{   _jetSprite:null,
    init:function(){
          this._super();
          this.initWithColor(new cc.Color4B(0,0,0,255));
          var size = cc.Director.getInstance().getWinSize();
.......

Thanks in advance.

Try this.init(color, width, height)

#3

Tried that, but gives “Uncaught RangeError: Maximum call stack size exceeded” error, in CCGeometry.js:1.

Yeah I got this same error.

Hi, the tutorials on gamefromscratch are for cocos2d-html5 2.0

since then, the api has changed a little.

for this sample to work

init:function(){
this._super(new cc.Color4B(0,0,0,255));
//this.initWithColor(new cc.Color4B(0,0,0,255));

You’re fix is not works with Cocos2d-html5 v2.2.2.

How could we solve this?

Hi, @alienwoods

You should use this.init( cc.c4b(0,0,0,255) )

@pandamicro
but a new error is

Uncaught RangeError: Maximum call stack size exceeded

firfox crashed during launching.

Ah, that’s because the init function have been override by your own init, so you need to do this:

var MyLayer = cc.LayerColor.extend({
	init:function(){
		this._super();
		cc.LayerColor.prototype.init.call( this, new cc.c4b(0,0,0,255) );
		// ...
	}
});
