Cocos2d-x-3.x版 Js Binding 的手动绑定实现

概述网上流传的是一份2.x版本的，现在已更新到3.x，经过千辛万苦，终于调试成功。 1 .首先定义待绑定的类 AnimationKoo.h#ifndef __AnimationKoo_H__#define __AnimationKoo_H__namespace ls{ class AnimationKoo{ public: virtual void funcTest();

网上流传的是一份2.x版本的，现在已更新到3.x，经过千辛万苦，终于调试成功。

1 .首先定义待绑定的类

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;}

定义类在ls命名空间，我们测试funcTest方法

2，添加绑定代码到AppDelegate的类

在applicationDIDFinishLaunching方法里面，添加sc->addRegisterCallback(register_all_ls);//手动绑定的类

编写Jsb_ls_auto.h，如下

#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,Jsval *vp);bool  Js_cocos2dx_AnimationkooFuncTest_getDescription(jscontext *cx,Jsval *vp);bool  Js_cocos2dx_Animationkoo_constructor(jscontext *cx,Jsval *vp);voID  register_all_ls(jscontext* cx,Js::HandleObject obj);

没错，就是这么坑爹，需要写这么多东西。

下面是它的实现

Jsb_ls_auto.cpp

#include "cocos2d.h"#include "koogame/Animationkoo.h"#include "JsAPI.h"#include "Jsb_ls_auto.h"#include "cocos2d_specifics.hpp"// 定义 Js 端的类型JsClass  *Jsb_LsLeafsoar_class;JsObject *Jsb_LsLeafsoar_prototype;// 实现 ls 命名空间下的类绑定voID register_all_ls(jscontext* cx,Js::HandleObject obj) {    Js::Rootedobject ns(cx);    get_or_create_Js_obj(cx,obj,"ls",&ns);    // 实现绑定 Leafsoar 类，它的定义后文给出    Js_register_ls_Animationkoo(cx,ns);}voID Js_cocos2d_Animationkoo_finalize(JsFreeOp *fop,JsObject *obj) {    cclOGINFO("Jsbindings: finalizing Js object %p (Node)",obj);}bool Js_cocos2dx_Animationkoo_create(jscontext *cx,Jsval *vp){    Js::CallArgs args = Js::CallArgsFromVp(argc,vp);    if (argc == 0) {		ls::AnimationKoo* ret = ls::AnimationKoo::create();        Jsval Jsret = JsVAL_NulL;        do {        if (ret) {            Js_proxy_t *JsProxy = Js_get_or_create_proxy<ls::AnimationKoo>(cx,(ls::AnimationKoo*)ret);            Jsret = OBJECT_TO_JsVAL(JsProxy->obj);        } else {            Jsret = JsVAL_NulL;        }    } while (0);        args.rval().set(Jsret);        return true;    }    Js_ReportError(cx,"Js_cocos2dx_Animationkoo_create : wrong number of arguments");    return false;}static bool Js_is_native_obj(jscontext *cx,vp);    args.rval().setBoolean(true);    return true;    }bool Js_cocos2dx_AnimationkooFuncTest_getDescription(jscontext *cx,vp);    Js::Rootedobject obj(cx,args.thisv().toObjectOrNull());    Js_proxy_t *proxy = Jsb_get_Js_proxy(obj);    ls::AnimationKoo* cobj = (ls::AnimationKoo *)(proxy ?

这次要写的更多了。

离成功就差一步了。cocos2d Js中测试

var animationKoo =ls.AnimationKoo.create();

animationKoo.functest();

输出binding test...，成功
