我写了这个剧本，出于某种原因，我离开地面后最多可以跳两次。这真的很奇怪，因为正如你所看到的，maxJumps被设置为1。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    private float horizontal;
    private float speed = 8f;
    private float jumpingPower = 16f;
    private bool isFacingRight = true;
    private bool isGrounded = false;
    public float maxJumps = 1;
    private float currentJumps;

    public float coyoteTimerMax = .03f;
    private float coyoteTimer;

    private float jumpBuffer;
    public float maxJumpBuffer = .04f;

    [SerializeField] private Rigidbody2D rb;
    [SerializeField] private Transform groundCheck;
    [SerializeField] private LayerMask groundLayer;

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        horizontal = Input.GetAxisRaw("Horizontal");

        if (Input.GetButtonDown("Jump"))
        {
            jumpBuffer = maxJumpBuffer;
        }
        

        if (isGrounded)
        {
            currentJumps = 0; 
            coyoteTimer = coyoteTimerMax;
            
        }
        else
        {
            coyoteTimer -= Time.deltaTime;
            
        }

        jumpBuffer -= Time.deltaTime;

        if (jumpBuffer > 0 && coyoteTimer > 0 && currentJumps < maxJumps)
        {
            rb.velocity = new Vector2(rb.velocity.x, jumpingPower);
            currentJumps++;
            jumpBuffer = 0; // Reset the jump buffer after successfully jumping
        }

        if (Input.GetButtonUp("Jump") && rb.velocity.y > 0)
        {
            rb.velocity = new Vector2(rb.velocity.x, rb.velocity.y * 0.5f);
        }

        
        

        

        Flip();

        
    }

    private void FixedUpdate()
    {
        rb.velocity = new Vector2(horizontal * speed, rb.velocity.y);
    }

    void OnCollisionEnter2D(Collision2D other)
    {
        if (other.gameObject.CompareTag("Ground"))
        {
            isGrounded = true;
        }
    }

    void OnCollisionExit2D(Collision2D other)
    {
        if (other.gameObject.CompareTag("Ground"))
        {
            isGrounded = false;
        }
    }

        private void Flip()
    {
        if (isFacingRight && horizontal < 0f || !isFacingRight && horizontal > 0f)
        {
            isFacingRight = !isFacingRight;
            Vector3 localScale = transform.localScale;
            localScale.x *= -1f;
            transform.localScale = localScale;

        }
    }
}
