Question

我有很多问题要解决。我看到很多指南如何解决我的问题，但他们都建议添加我的地面检查已经有了，所以我不知道问题是什么。当我希望我的玩家跳跃时，他会跳跃并且永不返回（他处于无限跳跃中，继续向上）谢谢:)

代码：

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

public class PlayerManager : MonoBehaviour
{
    public float movmentSpeed;
    public float jumpForce;
   
    public Transform groundCheck;
    public LayerMask groundLayer;
   
   public bool isGrounded;
    private SpriteRenderer spriteRender;

    private Rigidbody2D rb2D;
   

    private void Start()
    {
        rb2D = GetComponent<Rigidbody2D>();
        spriteRender = GetComponent<SpriteRenderer>();
    }

    private void FixedUpdate()
    {

        PlayerMovementHandle();

        
    }

    public void PlayerMovementHandle()
    {
        GroundCheck();

        var movement = Input.GetAxis("Horizontal");
        rb2D.velocity = new Vector2(movement, rb2D.velocity.y)*movmentSpeed*Time.fixedDeltaTime;

        Flip();
        Jump();
     
    } 

    void GroundCheck()
    {
        isGrounded = false;

        Collider2D[] colliders = Physics2D.OverlapCircleAll(groundCheck.position, 0.2f, groundLayer);
        if (colliders.Length>0)
        {
            isGrounded = true;
        }
    }

    public void Jump()
    {

        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (isGrounded)
            {
               // rb2D.velocity = Vector2.up * jumpForce;
                 rb2D.AddForce(new Vector2(0, jumpForce), ForceMode2D.Impulse);
    
            }

        }
    }

    public void Flip()
    {
        if (rb2D.velocity.x < -0.1f)
        {
            spriteRender.flipX = true;
        }
        else if (rb2D.velocity.x > 0.1f)
        {
            spriteRender.flipX = false;
        }
    }

  
}

在 movmentSpeed*Time.fixedDeltaTime 中乘以您的 y 值 FixedUpdate 将使您的角色沿 y 方向移动。

rb2D.velocity = new Vector2(movement, rb2D.velocity.y)*movmentSpeed*Time.fixedDeltaTime;

尝试将 y 值设为 0 并让 Jump() 方法进行跳转。

rb2D.velocity = new Vector2(movement, 0f)*movmentSpeed*Time.fixedDeltaTime;
