测试 tolua 例子 TestErrorStack

(金庆的专栏 2020.9)

Error1

  1. 点击 “Error1” 按钮
  2. c# showStack.PCall()
  3. lua ShowStack()
  4. c# Test1()
  5. c# try { show.PCall() }
  6. lua Show() error(‘this is error’)
LuaException: TestErrorStack:2: this is error
stack traceback:
	[C]: in function 'error'
	TestErrorStack:2: in function 
	[C]: in function 'Test1'
	TestErrorStack:6: in function 
LuaInterface.LuaState:PCall(Int32, Int32) (at Assets/ToLua/Core/LuaState.cs:758)
LuaInterface.LuaFunction:PCall() (at Assets/ToLua/Core/LuaFunction.cs:96)
TestLuaStack:Test1(IntPtr) (at Assets/ToLua/Examples/TestErrorStack/TestLuaStack.cs:27)
LuaInterface.LuaDLL:lua_pcall(IntPtr, Int32, Int32, Int32)
LuaInterface.LuaState:PCall(Int32, Int32) (at Assets/ToLua/Core/LuaState.cs:755)
LuaInterface.LuaFunction:PCall() (at Assets/ToLua/Core/LuaFunction.cs:96)
TestLuaStack:OnGUI() (at Assets/ToLua/Examples/TestErrorStack/TestLuaStack.cs:375)

lua Show() 中抛 error, 在 C# 中 try-catch 得到,
通过 toluaL_exception() 返回 Lua 调用者 ShowStack(),
ShowStack() 中止执行,传递异常到 c# 调用者 OnGUI(),
OnGUI()中断执行,打印错误信息。

Instantiate Error

  1. “Instantiate Error”
  2. c# GetFunction(“Instantiate”).PCall()
  3. lua Instantiate()
  4. c# UnityEngine.Object.Instantiate(obj)
  5. c# TestInstantiate.Awake()
  6. c# try { GetFunction(“Show”).PCall() }
  7. lua Show()
  8. c# state.ThrowLuaException(e)
LuaException: TestErrorStack:2: this is error
stack traceback:
	[C]: in function 'error'
	TestErrorStack:2: in function 
	[C]: in function 'Instantiate'
	TestErrorStack:12: in function 
LuaInterface.LuaState:PCall(Int32, Int32) (at Assets/ToLua/Core/LuaState.cs:758)
LuaInterface.LuaFunction:PCall() (at Assets/ToLua/Core/LuaFunction.cs:96)
TestInstantiate:Awake() (at Assets/ToLua/Examples/TestErrorStack/TestInstantiate.cs:15)
UnityEngine.Object:Instantiate(Object)
UnityEngine_ObjectWrap:Instantiate(IntPtr) (at Assets/ToLua/BaseType/UnityEngine_ObjectWrap.cs:203)
LuaInterface.LuaDLL:lua_pcall(IntPtr, Int32, Int32, Int32)
LuaInterface.LuaState:PCall(Int32, Int32) (at Assets/ToLua/Core/LuaState.cs:755)
LuaInterface.LuaFunction:PCall() (at Assets/ToLua/Core/LuaFunction.cs:96)
TestLuaStack:OnGUI() (at Assets/ToLua/Examples/TestErrorStack/TestLuaStack.cs:391)

在 lua 中实例化对象,Awake() 中向lua抛异常:state.ThrowLuaException(e)。
中止了 lua 调用和 OnGUI(), 但是新对象的 Start() 成功调用了。
因为 Awake() 中 catch 了异常,按执行成功处理。
如果 Awake() 中不 catch, Awake() 执行异常,也不会有 Start() 调用,但是lua Instantiate() 执行会成功,打印出对象名。

  1. “Check Error”
  2. c# GetFunction(“TestRay”).PCall()
  3. lua TestRay() return Vector3.zero
  4. c# CheckRay(); //返回值出错
