luajavabridge 使用过程出现问题的总结

sig 函数参数表说明一定要写正确

否则调用的过程会出现Failed to find method id 错误，jvm查找不到函数id

package com.cocos2dx.sample.LuaJavaBridgeTest;

import org.cocos2dx.lib.Cocos2dxLuaJavaBridge;

public class LuaJavaBridgeTest
{
public static int addTwoNumbers(final int num1,final int num2){
return num1 + num2;
}

public static void callbackLua(final String tipInfo,final int luaFunc){
Cocos2dxLuaJavaBridge.callLuaFunctionWithString(luaFunc, "success");
Cocos2dxLuaJavaBridge.releaseLuaFunction(luaFunc);
}
}

比如上面的这个例子

在 lua中这样调用

local args = { 2 , 3}

local sigs = "(II)I"

local luaj = require "cocos.cocos2d.luaj"

local className = "com/cocos2dx/sample/LuaJavaBridgeTest/LuaJavaBridgeTest"

local ok,ret = luaj.callStaticMethod(className,"addTwoNumbers",args,sigs)

sigs表示两个int型整数，一个int型返回值
