跳转/投掷编码或动画问题

设置

我有一个带动画师的篮球运动员，并为动画师分配了5个动画，如下所示：

1. PlayerIdle
2. PlayerWalk
3. PlayerJump
4. PlayerBend
5. PlayerShoot

问题

在PlayMode中，播放器能够成功移动和跳跃。当玩家尝试抓住地面上的苹果时，就会出现问题。我想要的理想游戏设计是让玩家弯腰抓住苹果，方法是按G键，然后再次按G键，将苹果向篮筐扔一分。但是，当我运行它并首次按下G后，玩家将无法再跳，抓或扔。下一节是PlayerMovement和GrabberScript的代码。任何建议都将不胜感激。

PlayerMovement.cs

public class PlayerMovement : MonoBehaviour

        rb = GameObject.Find("Player Parent").GetComponent<Rigidbody2D>();
        anim = GameObject.Find("Player Parent").GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        CheckIfGrounded();
        PlayerJump();
    }

    private void FixedUpdate()
    {
        PlayerWalk();
    }

    void PlayerWalk()
    {
        float h = Input.GetAxisRaw("Horizontal");

        if (h > 0)

            rb.velocity = new Vector2(speed, rb.velocity.y);
            ChangeDirection(-1);
        }

Answer 1

我们可以看到您的动画师状态吗？我认为没有办法从动画师的“ PlayerBend”状态退回。在您的步行代码中，您正在更改“ isWalking”布尔值，但是如果您处于正确的状态，它将起作用。所以我的建议是开始游戏并仔细检查动画师的状态。
