unity trigger 獲取觸發點

2D

    private void OnTriggerEnter2D(Collider2D other)
    {
        if (other.gameObject.GetComponent<AttackBox>())
        {
            hitPos = other.bounds.ClosestPoint(transform.position);
            print("碰撞點" + hisPos);
        }
    }

 

3D

other.gameObject.GetComponent<Collider>().ClosestPointOnBounds(transform.position);

 

注意這種方法不推薦單場景里過多使用，會產生大量的GC 影響幀率
