c++ - 传递数组时类中出现错误指针错误

Question

所以我正在为游戏编写一个简单的战斗系统，但我在将一组指针传递给战斗系统类时遇到错误。

//Create the player and 3 enemies
Battler player("Player", 100, 100, 50, 50, 50, 50, 90);
Battler foe1("Imp", 100, 100, 50, 50, 50, 50, 80);
Battler foe2("Ogre", 100, 100, 50, 50, 50, 50, 75);
Battler foe3("Giant", 100, 100, 50, 50, 50, 50, 60);

//Create an array of pointers that point to the enemies
Battler *foes[3];
foes[0] = &foe1;
foes[1] = &foe2;
foes[2] = &foe3;

//Initialize the battlesystem passing the player, the array of enemies 
//and the number of enemies (3)
BattleSystem *btl = new BattleSystem(&player, *foes, 3);

所以这工作正常，但是当我将数组传递给类时，第一个成员传递正常，但其余成员传递，当我执行断点时，它们作为“Badptr”发送。

这是战斗系统构造函数的代码:

BattleSystem::BattleSystem(Battler *plyr, Battler enemies[], int numEnemies)
{
    player = plyr;

    //foe is declared as    Battler *foe;   So it just points to the first member of the enemies
    // array so I can access them. But only the first member gets a value the rest get
    // "Bad ptr" with garbage values and when I look through the enemies array passed
    // to the constructor, it has BAD PTRs in everything but the first element.
    foe = enemies;
    numFoes = numEnemies;

    totalTurns = 0;

    foeTurns = new int[numFoes];
    turnList = new Battler*[numFoes + 1];

    for(int i = 0; i <= numFoes; i++)
    {
        turnList[i] = &foe[i];
    }

    turnList[numFoes + 1] = player1;

我想我遗漏了一些明显的东西，但任何人都可以分享一些智慧吗？

谢谢。

抛开关于裸指针和所有权的样式问题，我相信你的意思是

//                                                v-- array of pointers
BattleSystem::BattleSystem(Battler *plyr, Battler *enemies[], int numEnemies)

和

BattleSystem *btl = new BattleSystem(&player, foes, 3);
