c# - 如何调用具有 bool 值 true unity C# 的数组元素

Question

我有四个按钮使用相同的预制件并保存数组中的 4 个文本元素，其中只有一个被分配 bool 值为 true。单击任何 false 元素时，我试图访问该 true 元素。我想在单击错误元素时突出显示真实元素。谁能帮我实现这个功能？ 使用简单对象池 引用统一问答游戏教程 谢谢

Answer 1

为了同时突出显示“错误”(单击的按钮)和“正确”按钮，您需要能够访问这两个按钮。这意味着您无法通过应答按钮脚本的 HandleClick 方法进行突出显示，因为它只能访问自身，例如到错误的按钮。

好处是这个方法会通知 GameController 按钮已被点击。 GameController 知道所有的按钮，因此它可以轻松地突出显示两个按钮。

因此，您应该从 GameController 的 AnswerButtonClicked 执行此操作，而不是从 Answer Button 的 HandleClick 启动高亮显示子例程:在此处识别右键和单击的按钮并为它们启动适当的子例程。

更新:

例如，您的 ReturnCorrectButtonColor 看起来像:

IEnumerator ReturnCorrectButtonColor( GameObject button )
{
    Debug.Log("im correct");
    button.GetComponent<Button>().image.color = Color.green;
    yield return new WaitForSeconds(seconds: 2.9f);
    button.GetComponent<Button>().image.color = Color.white;
}

所以在 AnswerButtonClicked 中，您确定要突出显示哪个按钮作为正确答案按钮，并将其作为参数传递给此方法:

StartCoroutine(ReturnCorrectButtonColor(correctButton));
