Unity接入XLua问题汇总

一、This type must add to CSharpCallLua

二、Type cannot be null in method 'GetComponent'

一、This type must add to CSharpCallLua

如Unity中更新XLua时遇到

1. LuaException: c# exception:This type must add to CSharpCallLua: UnityEngine.Events.UnityAction<float>
3. LuaException: c# exception:System.InvalidCastException: This type must add to CSharpCallLua: System.Action<bool>

复制代码

在XLua ExampleConfig.cs中添加如下配置，然后重新 Generate Code 即可

1. //C#静态调用Lua的配置（包括事件的原型），仅可以配delegate，interface
2.     [CSharpCallLua]
3.     public static List<Type> CSharpCallLua = new List<Type>() {
4.             typeof(Action),
5.             typeof(Func<double, double, double>),
6.             typeof(Action<string>),
7.             typeof(Action<double>),
8.             typeof(Action<bool>),
9.             typeof(Action<float>),
10.             typeof(UnityEngine.Events.UnityAction),
11.         };

二、Type cannot be null in method ‘GetComponent’

1. LuaException: c# exception:Type cannot be null.,stack:  at System.Reflection.MonoMethod.Invoke (System.Object obj, System.Reflection.BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <00000000000000000000000000000000>:0
2.       at XLua.OverloadMethodWrap.Call (System.IntPtr L) [0x00000] in <00000000000000000000000000000000>:0
3.       at XLua.MethodWrap.Call (System.IntPtr L) [0x00000] in <00000000000000000000000000000000>:0
4.       at XLua.StaticLuaCallbacks.FixCSFunction (System.IntPtr L) [0x00000] in <00000000000000000000000000000000>:0
5.     stack traceback:
6.             [C]: in method 'GetComponent'

出错行代码

1. closeButton:GetComponent("Button").onClick:AddListener(self:OnClose(true))

复制代码

将通过 “Button” 字符串获取组件改为 通过 typeof(Button) 获取组件。修改为如下：

1. closeButton:GetComponent(typeof(Button)).onClick:AddListener(self:OnClose(true))
