error C2664: 'KaibaMainPhase' : cannot convert parameter 1 from

你的錯誤信息應該引用你到一個特定的行。請說明哪一行。另外，考慮從問題中刪除一些不相關的代碼，並*實際*提出問題。我在這裏沒有看到任何問題。（提示：問題以問號結尾） – abelenky

你知道'typedef'是什麼以及如何使用它？ –

我的哀悼，這段代碼看起來難以逾越，無法維持。祝你好運。也許首先將'vector >＆Field'這樣的東西分解到它們自己的類中，併爲它們提供一些方法來處理'Field'對象應該做的事情？ – sarnold

在這一行：

void KaibaMainPhase(void (*)(vector< vector<Card> > &Field, vector<Card> &KaibaGraveyard, vector<Card> &YugiGraveyard), vect....

您聲明第一個參數爲KaibaMainPhase將是3個參數的函數。

void KaibaMainPhase(
    /* Function Pointer */ void (*)(
    /* Param #1   */ vector< vector<Card> > &Field, 
    /* Param #2   */ vector<Card> &KaibaGraveyard, 
    /* Param #3   */ vector<Card> &YugiGraveyard), /*other parameters to KaibaMainPhase*/....

後來，在此代碼：

pFunct[0] = HEAVYSTORM; 
[...] 
KaibaMainPhase(pFunct, KaibaHand, Kaiba.....

你傳入pFunct，這是兩種不同的功能的陣列。
數組與函數指針不同。

但是，即使你確實通過了pFunct[0]，它也不起作用。 pFunct被聲明爲函數指針陣列，其中每個函數具有參數：

/* Array of 2 fnct ptrs */ void (* pFunct[2])(
/* Param #1 */ vector<Card> &KaibaHand, 
/* Param #2 */ vector<Card> &KaibaDeck, 
/* Param #3 */ vector< vector<Card> > &Field, 
/* Param #4 */ vector<Card> &KaibaGraveyard, 
/* Param #5 */ vector<Card> &YugiGraveyard 
);

但功能KaibaMainPhase期待一個函數，只需要參數。
