Re: I need some help on extended class

I register a c++ class CCLayer

    luabind::module(L)[
                     class_<CCLayer,CCNode,CCLayer_wrap,boost::shared_ptr<CCLayer> >("CCLayer")
                    .def(constructor<>())
                    .scope[
                     def("node",&CCLayer::node)
                     ]
                     .def("init", &CCLayer::init, &CCLayer_wrap::default_init)
                     .def("addChild",(void(CCLayer::*)(CCNode * ))&CCLayer::addChild,&CCLayer_wrap::default_addChild)
          ];

then

extends it on lua script:

     "class 'HelloWorld' (CCLayer)\n"
     " function HelloWorld:__init() CCLayer.__init(self) end\n"
     " function HelloWorld:addChild(ccnd) printLog('addChild') ss = self.super ss:addChild(ccnd) end\n"
     " function HelloWorld:init() "
     "      printLog('HelloWorld:init()')"
     "      ccs = CCSprite()"
     "      printLog('ccs = CCSprite()')"
     "      ccs:initWithFile('HelloWorld.png')"
     "      printLog('ccs:initWithFile1')"
     "      self:addChild(ccs)"
     "      printLog('self:addChild')"
     " end\n"

but ss:addChild(ccnd) didn't work.

Could you tell me why?

Re: I need some help on extended class

If you intend to call the parent function, try this:

CCLayer.addChild(self,ccnd)
