Unity 2D 物体旋转指向目标

public class RoleStand : PlayerAction
{

    PlayerControl playerCtrl = null;
    public override ActionType Name => ActionType.Stand;
    public override bool IsCanMove => false;
    public override bool IsCtrlFree => false;
    public override void Enter(IPlayerControl _player, EventParam _param)
    {
        playerCtrl = _player as PlayerControl;
        playerCtrl._animator.Play("idle", true);
    }

    public override void Exit()
    {

    }

    public override void _Update()
    {
        if (XJoystick.IsInput)
        {
            Vector3 dir = new Vector3(XJoystick.AxisData.x, XJoystick.AxisData.y,0);
            float angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
            transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
        }
    }
}

Vector2 direction = target.transform.position - transform.position;
  float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
  transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);

效果如下：
