Manual Binding implementation of Js Binding for Cocos2d-x-3.x Edition

Manual Binding implementation of Js Binding for Cocos2d-x-3.x Edition

A version of 2.x has been circulated on the Internet and has been updated to 3.x. after great efforts, debugging has finally been successful.

1. First define the class to be bound

 

AnimationKoo.h#ifndef __AnimationKoo_H__#define __AnimationKoo_H__namespace ls{class AnimationKoo{public:virtual void funcTest();static AnimationKoo * create();};}#endif // __AnimationKoo_H__AnimationKoo.cpp#include "cocos2d.h"#include "cocos2d_specifics.hpp"#include " AnimationKoo.h"void ls::AnimationKoo::funcTest(){CCLOG("binding test...");}ls::AnimationKoo * ls::AnimationKoo::create(){    AnimationKoo * ret = new AnimationKoo();    return ret;}

 

Define the class in the ls namespace. Let's test the funcTest method.

 

2. Add the binding codeAppDelegateClass

In the applicationDidFinishLaunching method, add SC-> gisgistercallback (register_all_ls); // manually bound class.

WriteJsb_ls_auto.h, As shown below

#include "jsapi.h"#include "jsfriendapi.h"#include "ScriptingCore.h"void  js_register_ls_Animationkoo(JSContext* cx, JS::HandleObject global);void  js_cocos2d_Animationkoo_finalize(JSFreeOp *fop, JSObject *obj);bool  js_cocos2dx_Animationkoo_create(JSContext *cx, uint32_t argc, jsval *vp);static bool  js_is_native_obj(JSContext *cx, uint32_t argc, jsval *vp);bool  js_cocos2dx_AnimationkooFuncTest_getDescription(JSContext *cx, uint32_t argc, jsval *vp);bool  js_cocos2dx_Animationkoo_constructor(JSContext *cx, uint32_t argc, jsval *vp);void  register_all_ls(JSContext* cx, JS::HandleObject obj);

That's right. It's such a pitfall. You need to write so many things.

 

Below is its implementation

T; js_type_class_t * p; std: string typeName = t. s_name (); if (_ js_global_type_map.find (typeName) = _ dependencies () {p = (js_type_class_t *) malloc (sizeof (js_type_class_t); p-> jsclass = callback; p-> proto = jsb_LsLeafsoar_prototype; p-> parentProto = NULL; _ js_global_type_map.insert (std: make_pair (typeName, p ));}}
    
   
  
 

This time I want to write more.

 

This is only one step away from success. Test in cocos2d js

Var animationKoo = ls. AnimationKoo. create ();

AnimationKoo. funcTest ();

 

Binding test... output, succeeded
