C# 如何使用两个相同的长方体碰撞器打开相同的动画？

我在游戏中有一个关卡，当你进入一个盒子对撞机时，一个入口打开，当你离开它时，它关闭。当我进入框碰撞器1时，两个入口都需要打开，当我离开时，两个入口都需要关闭。当我进入第二个入口的框碰撞器2时，这也需要发生。我有一个用于box collider 1的脚本，并将其应用于box collider 2。它检查玩家是否在对撞机中。我有一个动画师bool，它直接从框碰撞器脚本中获取变量以检入范围。我用那玩意儿做动画。然而，那个动画师布尔森并不为《盒子碰撞2》工作。“长方体碰撞器”（box collider）的变量可以工作，但动画师布尔（animator bool）不能工作。有没有办法连接第二个，或者我需要为那个盒子碰撞器制作一个新的脚本

长方体碰撞器代码：

门户脚本代码：

一幅情景图：

首先，您不应该在每一帧都使用GetComponent。无论是喜欢动画，你都应该立即保存它。或者，您可以简单地将portalOrder设置为portalOrder类型，然后在通过Inspector引用时自动设置相应的引用

然后是，当前您只更新一个动画师。为了控制它们，你必须以某种方式连接它们

我会这样做

public class Portal : MonoBehaviour 
{
    private Animator anim;
    private bool inPortalRange;
    // Public read-only access
    public bool InPortalRange => inPortalRange;

    // Reference each other via the Inspector in both portals
    public Portal OtherPortal;

    // Give this directly the according type so you don't need GetComponent at all
    public PortalBorder portalBorder;

    // I would recommend to do things always as early as possible
    // Awake is executed before Start
    private void Awake()
    {
        anim = GetComponent<Animator>();
    }

    private void Update ()
    {
        OpenPortal();
        UpdateAnimation();
    }

    private void UpdateAnimation()
    {
        // Here now use the range of either this or the other portal
        anim.SetBool("inPortalRange", InPortalRange || OtherPortal.inPortalRange );
    }

    private void OpenPortal()
    {
        inPortalRange = portalBorder.inRange;
    }
}

现在，您的脚本必须像单击按钮一样，可以通过检查器或使用代码添加回调

public class Portal : MonoBehaviour 
{
    public Animator anim;
    private bool inPortalRange;
    // Public read-only access
    public bool InPortalRange => inPortalRange;

    // Reference each other via the Inspector in both portals
    public Portal OtherPortal;

    // Give this directly the according type so you don't need GetComponent at all
    public PortalBorder portalBorder;

    // I would recommend to do things always as early as possible
    // Awake is executed before Start
    private void Awake()
    {
        anim = GetComponent<Animator>();

        // Instead of checking a bool in Update simply
        // wait until the according events get invoked
        portalBorder.OnEnteredPortalRange.AddListener(EnablePortal);
        portalBorder.OnLeftPortalRange.AddListener(DisablePortal);
    }

    private void OnDestroy()
    {
        // always make sure to remove callbacks when not needed anymore
        // in roder to avoid NullReferenceExceptions
        portalBorder.OnEnteredPortalRange.RemoveListener(EnablePortal);
        portalBorder.OnLeftPortalRange.RemoveListener(DisablePortal);
    }

    public void EnablePortal()
    {
        anim.SetBool("inPortalRange", true);
        OtherPortal.anim.SetBool("inPortalRange", true);
    }

    public void DisablePortal()
    {
        anim.SetBool("inPortalRange", false);
        OtherPortal.anim.SetBool("inPortalRange", false);
    }
}
