我们如何使用SetActive关闭一组GameObjects？

Question

我有4个按钮。每个按钮都会打开游戏对象并关闭其他三个按钮。

有没有比我下面更好的方法。

public void Button1() {
    gameObject1.SetActive(true);
    gameObject2.SetActive(false);
    gameObject3.SetActive(false);
    gameObject4.SetActive(false);
}

public void Button2()
{
    gameObject1.SetActive(false);
    gameObject2.SetActive(true);
    gameObject3.SetActive(false);
    gameObject4.SetActive(false);
}

public void Button3()
{
    gameObject1.SetActive(false);
    gameObject2.SetActive(false);
    gameObject3.SetActive(true);
    gameObject4.SetActive(false);
}

public void Button4()
{
    gameObject1.SetActive(false);
    gameObject2.SetActive(false);
    gameObject3.SetActive(false);
    gameObject4.SetActive(true);
}

Answer 1

我会这么说，是的。创建按钮游戏对象的数组并循环浏览该列表。我假设您在编辑器中设置了按钮关联：

（未测试的）

using System.Collections.Generic;

public class YourClass : MonoBehavour
{
    public GameObject gameObject1;
    public GameObject gameObject2;
    public GameObject gameObject3;
    public GameObject gameObject4;
    private List<GameObject> _buttons = null;

    void Start()
    {
        _buttons = new List<GameObject>();
        _buttons.Add(gameObject1);
        _buttons.Add(gameObject2);
        _buttons.Add(gameObject3);
        _buttons.Add(gameObject4);
        // Other stuff
    }

    public void Button1()
    {
        TurnOnButton(0);
    }

    public void Button2()
    {
        TurnOnButton(1);
    }

    public void Button3()
    {
        TurnOnButton(2);
    }

    public void Button4()
    {
        TurnOnButton(3);
    }

    private void TurnOnButton(int buttonNumber)
    {
        for (int i = 0; i < _buttons.Count(); i++) {
            _buttons[i].SetActive(i == buttonNumber);
        }
    }
