Question

我正在游戏中实现一个门户系统，但是有一点问题。我的播放器附有WorldInteraction脚本。每当玩家在门户上发生冲突时，玩家都需要按Enter键以选择位置。现在我的问题是为什么在按下Enter键后为什么控制台中的日志太多（出于测试目的）？例如，如果我在控制台中有3个日志，那么我的门户网站按钮也将是3。

这就是我在说的。请参见下面的屏幕截图：如您所见，控制台中有3个日志，按钮也相同。如何修复该错误？每个地图应该有1个按钮。

    private GameObject panel;

    void Start() {

    }

    public void ActivatePortal(Portal[] portals) {
        panel.SetActive (true);
        for (int i = 0; i < portals.Length; i++) {
            Button portalButton = Instantiate (button, panel.transform);
            portalButton.GetComponentInChildren<Text> ().text = portals [i].name;
            int x = i;
            portalButton.onClick.AddListener (delegate {
                OnPortalButtonClick (x, portals [x]);
            });

Portal.cs

public class Portal : ActionItem {
    public Vector3 TeleportLocation { get; set; }
    [SerializeField]
    private Portal[] linkedPortals;
    private PortalController portalController { get; set; }

    void Start () {
        portalController = FindObjectOfType<PortalController>();
        TeleportLocation = new Vector3(transform.position.x + 5f, transform.position.y, transform.position.z);
    }

    public override void Interact() {
        portalController.ActivatePortal(linkedPortals);
        Debug.Log ("Interacting with Portal");
    }
}

Interactable.cs

public class Interactable : MonoBehaviour {

    public virtual void MoveToInteraction() {
        Interact ();
    }

    public virtual void Interact() {
        Debug.Log ("Interacting with base class.");
    }
}

可能是因为在OnTriggerStay中调用了Input.GetKeyDown。之所以要在Update中调用Input.GetKeyDown以及类似的函数，是因为该状态会在每一帧重置。尝试将其移到那里。
