我对Unity和C#都很新,所以希望能得到任何帮助。
我让我的精灵跳起来了,这个功能运行良好,但是唯一会播放的动画是着陆动画。起飞动画不会播放,精灵在跳跃时保持静止状态,直到速度低于0时才播放着陆动画。
我做错了什么?我希望实现的是,在玩家跳起来时播放起飞动画,然后在下落时立即进入着陆动画。
这是我的代码:

{

myAnimator = GetComponent<Animator>();
}

{

}
// Update is called once per frame
void FixedUpdate()
{
float horizontal = Input.GetAxis("Horizontal");
HandleMovement(horizontal);
isGrounded = IsGrounded();

HandleLayers();
ResetValues();
}
private void HandleMovement(float horizontal)
{
if (myRigidbody.velocity.y < 0)
{
myAnimator.SetBool("land", true);
}
if (!myAnimator.GetBool("slide") && !this.myAnimator.GetCurrentAnimatorStateInfo(0).IsTag("Attack")&&(isGrounded || airControl))
{
myRigidbody.velocity = new Vector2(horizontal * movementSpeed, myRigidbody.velocity.y);
}
if (isGrounded && jump)
{
isGrounded = false;
myRigidbody.AddForce(new Vector2(0, jumpForce));
myAnimator.SetTrigger("jump");
}
if (slide && !this.myAnimator.GetCurrentAnimatorStateInfo(0).IsName("Slide"))
{
myAnimator.SetBool("slide", true);
}

{

}
myAnimator.SetFloat("speed", Mathf.Abs(horizontal));
}

{

}
}

{

}

{

}

{

}
}

for (int i = 0; i < colliders.Length; i++)
{
if (colliders[i].gameObject != gameObject)
{
myAnimator.ResetTrigger("jump");
myAnimator.SetBool("land", false);
return true;
}
}
}
}
return false;
}
private void HandleLayers()
{

}
}
}
