Question

对于所有这些我都是新手，所以对菜鸟的错误感到抱歉。我正在制作2D平台游戏我正在通过RayCast检查地面，并在玩家跳跃后立即将jumpCounter重置为0，因此我获得了奖励跳跃。我尝试添加一个0.2s的计时器，然后它才能重置，但是连续跳多次（兔子跳）时会造成麻烦。有帮助吗？

private void FixedUpdate()
    {
        GroundCheck();
        if (state != State.hurt)
        {
            Movement();
            DoubleJump();
            StateMachine();
        }

        HurtCheck();
        anim.SetInteger("state", (int)state);
    }
    private void Movement()
    {
        //Input.GetAxis returns a value between -1 up to 1
        //Edit> Project Settings> Input> Axis> Horizontal
        float hDirection = Input.GetAxisRaw("Horizontal");

        //holding down "D" makes the value positive and vice versa
        if (hDirection < 0)
        {
            rb.velocity = new Vector2(-speed, rb.velocity.y);
            transform.localScale = new Vector2(-1, 1);
        }
        else if (hDirection > 0)
        {
            rb.velocity = new Vector2(speed, rb.velocity.y);
            transform.localScale = new Vector2(1, 1);
        }
        else
        {

        }

        if (Input.GetButtonDown("Jump") && isGrounded == true)
        {
            Jump();
        }
    }
    private void Jump()
    {
        rb.velocity = new Vector2(rb.velocity.x, jumpforce);
        state = State.jumping;
        jumpCount += 1;
    }
    private void GroundCheck()
    {
        Debug.DrawRay(transform.position, Vector2.down * hitDistance, Color.green);
        RaycastHit2D hit = Physics2D.Raycast(transform.position, Vector2.down, hitDistance, ground);
        if(hit.collider != null)
        {
            isGrounded = true;
            jumpCount = 0;
        }
        else
        {
            isGrounded = false;
        }
    }
    private void DoubleJump()
    {
        if (Input.GetButtonDown("Jump") && isGrounded == false && jumpCount < 2)
        {
            rb.velocity = new Vector2(rb.velocity.x, jumpforce);
            jumpCount += 1;
        }
    }

嘿，您是否确定播放器的图层不是ground图层或没有正确设置ground图层蒙版，或者hitDistance的{{1}}太高了，应该非常低，例如raycast或更小，或者0.1从jumpCount或0开始尝试交替进行，或者让它从两个开始失去额外的奖金跳跃...这些就是我要看的地方，祝你好运！

跳转2D平台游戏后，JumpCount立即重置
