LuaFramework 框架下的Lua组件的实现

LuaComponent .cs

/* bo 2018-06-21 15:16:11 
 * 注意事项：
 * 1.必须在lua框架即LuaManager启动后使用
 * 2.lua类似于C#组件，通过C#转发达到调用组件方法的目的,方便用于对目前大量的C#UI进行一定能力的热更
 * 3.考虑调用性能问题，暂时不考虑Update系列方法
 * 4.LUA脚本路径的根路径为lua，此处路径填写lua文件夹下的文件路径，如：XXX | projx/UI/XXX
 * 5.约定lua形式如下：
local TestLuaComponent = {}

function TestLuaComponent:Awake( obj )
    -- body
    print("Awake:"..obj.name)
end

function TestLuaComponent:OnEnable( obj )
    -- body
    print("OnEnable:"..obj.name)
end

function TestLuaComponent:Start( obj )
    -- body
    print("Start:"..obj.name)
end

function TestLuaComponent:OnDisable()
    -- body
    print("OnDisable")
end

function TestLuaComponent:OnDestory()
    -- body
    print("OnDestory")
end

return TestLuaComponent

AddBundle方法

                {
                    bundleName = bundleName.Replace("lua/", "").Replace(".ab", "");
                    base.AddSearchBundle(bundleName.ToLower(), bundle);
                }
                return;
            }

            string url_SA = Util.SAPath() + bundleName.ToLower();
            AssetBundle bundle_SA = AssetBundle.LoadFromFile(url_SA);
            if (bundle_SA != null)
            {
                bundleName = bundleName.Replace("lua/", "").Replace(".ab", "");
                base.AddSearchBundle(bundleName.ToLower(), bundle_SA);
            }
        }
