這可以通過回調函數完成。發送一個指向一個函數的指針,從C#到C++將它存儲在一個臨時變量中。將Debug.Log
放入該回調函數中,並允許它作爲指針接收字符串(IntPtr
)。
當從C++調用此函數時,請將IntPtr
轉換爲帶有Marshal.PtrToStringAnsi
的字符串。
要使其在iOS上工作,您必須在回調函數中使用MonoPInvokeCallback
屬性。
C#(附加到一個空的遊戲物體):

// Use this for initialization

RegisterDebugCallback(OnDebugCallback);

enum Color { red, green, blue, black, white, yellow, orange };
[MonoPInvokeCallback(typeof(debugCallback))]
static void OnDebugCallback(IntPtr request, int color, int size)
{
//Ptr to string
string debug_string = Marshal.PtrToStringAnsi(request, size);
//Add Specified Color
debug_string =
String.Format("{0}{1}{2}{3}{4}",
"<color=",
((Color)color).ToString(),
">",
debug_string,
"</color>"
);
UnityEngine.Debug.Log(debug_string);
}
}

從C++用途:從所述編輯器
Debug::Log("Hellow Red", Color::Red);
Debug::Log("Hellow Green", Color::Green);
Debug::Log("Hellow Blue", Color::Blue);
Debug::Log("Hellow Black", Color::Black);
Debug::Log("Hellow White", Color::White);
Debug::Log("Hellow Yellow", Color::Yellow);
Debug::Log("Hellow Orange", Color::Orange);
Debug::Log(true, Color::Black);
Debug::Log(false, Color::Red);
輸出:

現在,您可以輕鬆實施Debug.LogWarning
和Debug.LogError
。

@Smartis謝謝。這看起來很有前途,但由於AOT,它不適用於iOS。這是一個好的開始。我會發布適用於iOS的答案,如果我得到它的工作。 – Programmer
