检测玩家和地面Unity3D之间的碰撞

我还在学习Unity,现在我试图让我的玩家能够跳跃。当然,我不希望我的玩家能够永远跳起来,所以我的想法是只在玩家与地板物体接触时启用跳跃。这是我到目前为止的代码:

public class PlayerController : NetworkBehaviour
{

    public float speed;             // Player movement speed
    private bool grounded = true;   // Contact with floor

    private Rigidbody rb;

    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    // Show a different color for local player to recognise its character
    public override void OnStartLocalPlayer()
    {
        GetComponent<MeshRenderer>().material.color = Color.red;
    }

    // Detect collision with floor
    void OnCollisionEnter(Collision hit)
    {
        if (hit.gameObject.tag == "Ground")
        {
            grounded = true;
        }
    }

    // Detect collision exit with floor
    void OnCollisionExit(Collision hit)
    {
        if (hit.gameObject.tag == "Ground")
        {
            grounded = false;
        }
    }

    void FixedUpdate()
    {
        // Make sure only local player can control the character
        if (!isLocalPlayer)
            return;

        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

        rb.AddForce(movement * speed);

        // Detect space key press and allow jump if collision with ground is true
        if (Input.GetKey("space") && grounded == true)
        {
            rb.AddForce(new Vector3(0, 1.0f, 0), ForceMode.Impulse);
        }
    }
}

但似乎OnCollisionEnterOnCollisionExit永远不会触发。所以玩家仍然可以随时跳跃。我做错了吗?

编辑:似乎OnCollisionEnterOnCollisionExit被触发完全正常。只是if语句返回false。我不知道为什么。

if (GameObject.Find("Ground") != null)返回true。

编辑2:奇怪的是,这两个都返回Untagged

Debug.Log(hit.gameObject.tag);
Debug.Log(hit.collider.tag);
