SLua-在Lua中实现Unity中的生命周期 Enumerable.Cast(IEnumerable) Method ： Casts the elements of an IEnumerable to the specified type. 将一个IEnumerable的元素转换为一个具体的类型。实现Unity中的Unity生命周期 1.获取Lua的表 2.获取表中的Update方法 3.使用强制类... 阅读详情

应用面：能用像写c#一样，在lua里实现业务功能，更好的理解lua

源码：

c#部分：我用的是xlua，注册方式使用[XLua.LuaCallCSharp]，tolua的注册方式自行查找


namespace Game.Scripts.Listener
{
    [DisallowMultipleComponent]
    [AddComponentMenu("")]  // Hide in 'Add Component' menu
    [XLua.LuaCallCSharp]
    public class StartListenerIL : MonoBehaviour
    {
        public event Action listeners;

        public void AddListener(Action func)
        {
            listeners += func;
        }

        public void RemoveListener(Action func)
        {
            listeners -= func;
        }

        private void Start()
        {
            listeners?.Invoke();
        }
    }
}

namespace Game.Scripts.Listener
{
    [DisallowMultipleComponent]
    [AddComponentMenu("")]  // Hide in 'Add Component' menu
    [XLua.LuaCallCSharp]
    public class EnableListenerIL : MonoBehaviour
    {
        public event Action listeners;

        public void AddListener(Action func)
        {
            listeners += func;
        }

        public void RemoveListener(Action func)
        {
            listeners -= func;
        }

        private void OnEnable()
        {
            listeners?.Invoke();
        }
    }
}


namespace Game.Scripts.Listener
{
    [DisallowMultipleComponent]
    [AddComponentMenu("")]  // Hide in 'Add Component' menu
    [XLua.LuaCallCSharp]
    public class DisableListenerIL : MonoBehaviour
    {
        public event Action listeners;

        public void AddListener(Action func)
        {
            listeners += func;
        }

        public void RemoveListener(Action func)
        {
            listeners -= func;
        }

        private void OnDisable()
        {
            if (listeners != null)
                listeners.Invoke();
        }
    }
}


namespace Game.Scripts.Listener
{
    [DisallowMultipleComponent]
    [AddComponentMenu("")]  // Hide in 'Add Component' menu
    [XLua.LuaCallCSharp]
    public class DestroyListenerIL : MonoBehaviour
    {
        public event Action listeners;

        public void AddListener(Action func)
        {
            listeners += func;
        }

        public void RemoveListener(Action func)
        {
            listeners -= func;
        }

        private void OnDestroy()
        {
            if(listeners != null)
                listeners.Invoke();
        }
    }
}


namespace Game.Scripts.Listener
{
    [DisallowMultipleComponent]
    [AddComponentMenu("")]  // Hide in 'Add Component' menu
    [XLua.LuaCallCSharp]
    public class UpdateListenerIL : MonoBehaviour
    {
        public event Action listeners;

        public void AddListener(Action func)
        {
            listeners += func;
        }

        public void RemoveListener(Action func)
        {
            listeners -= func;
        }

        private void Update()
        {
            listeners?.Invoke();
        }
    }
}

以上几个是常用的生命周期函数，后续想添加其他接口，按相同的方式添加代码

Lua部分：

local Helpers = {}

function Helpers.AddEnableListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.EnableListenerIL);
	local listener = tr:GetComponent(types);
	if listener == nil or listener:Equals(nil) then
		listener = tr.gameObject:AddComponent(typeof(types)) 
	end
	listener:AddListener(func);

	if tr.gameObject.activeInHierarchy and func ~= nil then
		func();
	end
end

function Helpers.RemoveEnableListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.EnableListenerIL);
	local listener = tr:GetComponent(types);
	if listener ~= nil then
		listener:RemoveListener(func);
	end
end

function Helpers.AddDisableListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.DisableListenerIL);
	local listener = tr:GetComponent(types);
	if listener == nil or listener:Equals(nil) then
		listener = tr.gameObject:AddComponent(typeof(types)) 
	end
	listener:AddListener(func);
end

function Helpers.RemoveDisableListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.DisableListenerIL);
	local listener = tr:GetComponent(types);
	if listener ~= nil then
		listener:RemoveListener(func);
	end
end

function Helpers.AddStartListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.StartListenerIL);
	local listener = tr:GetComponent(types);
	if listener == nil or listener:Equals(nil) then
		listener = tr.gameObject:AddComponent(typeof(types)) 
	end
	listener:AddListener(func)
end

function Helpers.RemoveStartListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.StartListenerIL);
	local listener = tr:GetComponent(types);
	if listener ~= nil then
		listener:RemoveListener(func);
	end
end

function Helpers.AddDestroyListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.DestroyListenerIL);
	local listener = tr:GetComponent(types);
	if listener == nil or listener:Equals(nil) then
		listener = tr.gameObject:AddComponent(typeof(types)) 
	end
	listener:AddListener(func)
end

function Helpers.RemoveDestroyListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.DestroyListenerIL);
	local listener = tr:GetComponent(types);
	if listener ~= nil then
		listener:RemoveListener(func);
	end
end

function Helpers.AddUpdateListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.UpdateListenerIL);
	local listener = tr:GetComponent(types);
	if listener == nil or listener:Equals(nil) then
		listener = tr.gameObject:AddComponent(typeof(types)) 
	end
	listener:AddListener(func)
end

function Helpers.RemoveUpdateListener(tr, func)

	local types = typeof(CS.Game.Scripts.Listener.UpdateListenerIL);
	local listener = tr:GetComponent(types);
	if listener ~= nil then
		listener:RemoveListener(func);
	end
end

return Helpers
