private IEnumerator KnockCo(Rigidbody2D enemy)

Vector2 forceDirection = enemy.transform.position - transform.position;
Vector2 force = forceDirection.Normalize() * thrust;
enemy.velocity = force;
yield return new WaitForSeconds(KnockTime);
enemy.velocity = new Vector2();
{
}
}
} }
forceDirection.Normize（）修改forceDirection向量并返回space，而不是返回归一化的向量。因此，您需要将Normize（）调用和乘法分解为单独的语句：
Vector2 forceDirection = enemy.transform.position - transform.position;
forceDirection.Normalize();
Vector2 force = forceDirection * thrust;
