Unity 2D击退，将transform.position改为AddForce？

Question

我试图让它在我的EnemyAI脚本中，当他们被子弹击中时，他们得到击退。我想用AddForce来代替，但我不知道该怎么改，有人能帮帮我吗？我的敌人在这段代码中已经有一个名为rb的Rigidbody2D。先谢谢你

    private void OnTriggerEnter2D(Collider2D other)
    {
        if(other.tag == "Bullet")
        {
            Vector2 difference = transform.position - other.transform.position;
            transform.position = new Vector2(transform.position.x + difference.x, transform.position.y + difference.y);
        }
    }

Answer 1

public float knockbackForce;

private void OnTriggerEnter2D(Collider2D other)
{
    if(other.tag == "Bullet")
    {
        Vector2 difference = (transform.position - other.transform.position).normalized;
        Vector2 force = difference * knockbackForce;
        rb.AddForce(force, ForceMode.Impulse); //if you don't want to take into consideration enemy's mass then use ForceMode.VelocityChange
    }
}
