物理对象卡在 EdgeColliders 中

Question

我正在使用来自 UnityCommunity Github 的 此代码 在屏幕边框周围创建边缘碰撞器：

public class ScreenEdgeColliders : MonoBehaviour
{
    private Camera cam;
    private EdgeCollider2D edge;
    private Vector2[] edgePoints;

    void Awake()
    {
        if (Camera.main == null) Debug.LogError("Camera.main not found, failed to create edge colliders");
        else cam = Camera.main;

        if (!cam.orthographic) Debug.LogError("Camera.main is not Orthographic, failed to create edge colliders");

        // add or use existing EdgeCollider2D
        edge = GetComponent<EdgeCollider2D>() == null ? gameObject.AddComponent<EdgeCollider2D>() : GetComponent<EdgeCollider2D>();

        edgePoints = new Vector2[5];

        AddCollider();
    }

    //Use this if you're okay with using the global fields and code in Awake() (more efficient)
    //You can just ignore/delete StandaloneAddCollider() if thats the case
    void AddCollider()
    {
        //Vector2's for the corners of the screen
        Vector2 bottomLeft = cam.ScreenToWorldPoint(new Vector3(0, 0, cam.nearClipPlane));
        Vector2 topRight = cam.ScreenToWorldPoint(new Vector3(cam.pixelWidth, cam.pixelHeight, cam.nearClipPlane));
        Vector2 topLeft = new Vector2(bottomLeft.x, topRight.y);
        Vector2 bottomRight = new Vector2(topRight.x, bottomLeft.y);

        //Update Vector2 array for edge collider
        edgePoints[0] = bottomLeft;
        edgePoints[1] = topLeft;
        edgePoints[2] = topRight;
        edgePoints[3] = bottomRight;
        edgePoints[4] = bottomLeft;

        edge.points = edgePoints;
    }

}

我将此脚本附加到我的主相机上。它运作得很好。物体被围住并且通常会从墙壁上反弹。问题是物体有时会卡在这些碰撞器中，我无法将它们拖离墙壁。我可以在这段代码中添加什么来确保对象不会卡住吗？

Answer 1

这更多是 Unity 的问题，而不是脚本的问题。尝试一下

• 将 Rigidbody 的检测设置为

  Extrapolate

  。
• 无论移动这些内容，都使用

  FixedUpdate

  而不是更新。

这通常对我有用。
