Question

确定我修复了错误，谢谢你们帮助了但是现在Unity在按下运行按钮的时候很多人因为循环而说很多人说但是我真的不知道如何解决它

以下代码会冻结游戏，因为test始终是false而永远不会true：

while (!test) {
choice = Random.Range (0, cards.Length);
test = !(cards [choice].GetComponent<Card> ().Initialized);
}

追踪到：

public bool Initialized {
    get { return initialized; }
    set { Initialized = value; }
}

因为set { Initialized = value; }应为set { initialized = value; }。

注意：

在使用生成的数字作为变量退出循环时，不要在while循环中生成随机数。如果失败，您将冻结Unity。在协程函数中执行此操作会很好，然后将yield return null;放在其末尾。这永远不会冻结Unity。

while (!test) {
choice = Random.Range (0, cards.Length);
test = !(cards [choice].GetComponent<Card> ().Initialized);
yield return null;
}

Unity继续崩溃
