Extend MenuItemSprite in JSB

cocos2d-x JavaScript
#1

Can someone tell me the proper way to extend a MenuItemSprite in JSB that will work with iOS? I’m need to override the selected and unselected functions within the MenuItemSprite class. Any help would be appreciated.

#2

You need to add cc.MenuItemSprite.extend = cc.Class.extend into the file: jsb_cocos2d.js

Thanks, but I’ve done that. Here is the simplest version of what I’m trying to do:

var MyMenuItemSprite = cc.MenuItemSprite.extend({

ctor:function(normal, pressed, released, target) {
this.*super;
this.initWithNormalSprite,
cc.Sprite.create, cc.Sprite.create,
this.clicked, this);
},
selected:function {
this.*super();
},

unselected:function() {
this._super();
},

clicked:function() {
// do nothing
}
});

This works in HTML5. In iOS, it gets an error on the initWithNormalSprite. Here is the error:

Assertion failure: !cx->isExceptionPending(), at …/jscntxtinlines.h:376

Yea, the method :initWithNormalSprite have not bound also, If you want to do like this, may be you need bound by yourself.

Any other way of doing it? I don’t know what “bound by yourself” means.

Looking at jsb_cocos2d_manual.mm there seems to be only a “init” method for javascript (which doesn’t seem to match the documentation) but if I try calling init I get a “Invalid Proxy object” error.
