在 Unity c# 中翻转精灵之前播放 2d 动画

Question

我实际上可以对敌人执行此操作，但由于某种原因，如果是玩家，我无法使其工作。

看，播放器处于默认的空闲动画中。当我从相反的方向按下箭头键时（默认是游戏开始时的右侧->），我希望它在精灵翻转其 x 比例之前播放转动动画。

但是，当我按下箭头键转动他时，它现在正在做什么，首先，它快速翻转精灵，然后执行动画，就好像它还没有翻转一样，然后翻转到另一个再次指向。

在我的动画师中，空闲没有到翻转节点的退出时间，而翻转节点确实有退出时间回到空闲，以防万一您询问。我也尝试过在这里和那里调用计时器，但到目前为止还没有运气。有人可以帮忙吗？

            anim.SetFloat ("walkSpeed", Mathf.Abs (move));

        }

在Update() 中执行任何动画后，您可以尝试翻转LateUpdate() 中的精灵。尝试类似的方法，将动画放在更新中：

// store references to components on the gameObject
Transform _transform;
Rigidbody2D _rigidbody;

// hold player motion in this timestep
float vx;
float vy;

float MoveSpeed;

void Awake () {

    // get a reference to the components we are going to be changing and store a reference for efficiency purposes
    transform = GetComponent<Transform> ();

    rigidbody = GetComponent<Rigidbody2D> ();

}

// this is where most of the player controller magic happens each game event loop
void Update()
{
    // determine horizontal velocity change based on the horizontal input
    vx = Input.GetAxisRaw ("Horizontal");

    // get the current vertical velocity from the rigidbody component
    vy = rigidbody.velocity.y;

    // Change the actual velocity on the rigidbody
    rigidbody.velocity = new Vector2(vx * MoveSpeed, vy);
}

// Checking to see if the sprite should be flipped
// this is done in LateUpdate since the Animator may override the localScale
// this code will flip the player even if the animator is controlling scale
void LateUpdate()
{
    // get the current scale
    Vector3 localScale = transform.localScale;

    if (vx > 0) // moving right so face right
    {
        facingRight = true;
    } else if (vx < 0) { // moving left so face left
        facingRight = false;
    }

    // check to see if scale x is right for the player
    // if not, multiple by -1 which is an easy way to flip a sprite
    if (((facingRight) && (localScale.x<0)) || ((!facingRight) && (localScale.x>0))) {
        localScale.x *= -1;
    }

    // update the scale
    transform.localScale = localScale;
}
