1、http://www.cocos2d-x.org/docs/manual/code-ide/function-guides/add-3rd-party-lib/binding-custom-class-to-js/zh

2、http://cocos2d.9tech.cn/news/2014/0106/39499.html

3、添加自定义类：SwimAlg

4、添加自定义函数：std::vector<Vec2> test(std::vector<Vec2> v){ return v;}5、添加自定义类型 std::vector<Vec2> (因为自带的没有该类型转换)：

在tools/bindings-generator/targets/spidermonkey/conversions.yaml 中添加代码

找到native_types: 在下面添加一行

"@std::vector<cocos2d::Vec2.*>.>": "std::vector<cocos2d::Vec2>"

找到 # int to jsval 在下面添加一行

"@vector<cocos2d::Vec2.*>": "${out_value} = std_vector_ccvec2_to_jsval(cx,${in_value})"

找到 # jsval to int 在下面添加一行

"@vector<cocos2d::Vec2.*>": "ok &= jsval_to_std_vector_ccvec2(cx,${in_value}, &${out_value})"

在frameworks/js-bindings/bindings/manual/js_manual_conversions中添加代码

jsval std_vector_ccvec2_to_jsval( JSContext *cx, const std::vector<cocos2d::Vec2>& v){    JS::RootedObject jsretArr(cx, JS_NewArrayObject(cx, 0));        int i = 0;    for (const cocos2d::Vec2 obj : v)    {        JS::RootedValue arrElement(cx);        arrElement = vector2_to_jsval(cx, obj);                if (!JS_SetElement(cx, jsretArr, i, arrElement)) {            break;        }        ++i;    }    return OBJECT_TO_JSVAL(jsretArr);}

bool jsval_to_std_vector_ccvec2( JSContext *cx, JS::HandleValue vp, std::vector<cocos2d::Vec2>* ret){    JS::RootedObject jsobj(cx);    bool ok = vp.isObject() && JS_ValueToObject( cx, vp, &jsobj );    JSB_PRECONDITION3( ok, cx, false, "Error converting value to object");    JSB_PRECONDITION3( jsobj && JS_IsArrayObject( cx, jsobj),  cx, false, "Object must be an array");        uint32_t len = 0;    JS_GetArrayLength(cx, jsobj, &len);        for (uint32_t i=0; i < len; i++)    {        JS::RootedValue value(cx);        if (JS_GetElement(cx, jsobj, i, &value))        {            if (value.isObject())            {                Vec2 v;                ok = jsval_to_vector2(cx, value, &v);                if (ok)                {                    ret->push_back(static_cast<Vec2>(v));                }            }            else            {                JS_ReportError(cx, "not supported type in array");                return false;            }        }    }        return true;}

5、以上可以在xcode上跑起来，如果需要打包安卓包，需要在Android.mk中添加

../../../js-bindings/cocos2d-x/cocos/user/SwimAlg.cpp\../../../custom/auto/jsb_SwimAlg.cpp \

$(LOCAL_PATH)/../../../js-bindings/cocos2d-x/cocos/user \
