public class Blogs : MonoBehaviour { private bool isMoving = false; private Vector2 moveDirection; private float moveDistance; public float speed; float timeTemp; public Vector2 clickPosition; public Transform targetPoint; public Vector3 localPosition; // Start is called before the first frame update void Start() { moveDirection = clickPosition - (Vector2)transform.position; moveDistance = moveDirection.magnitude; moveDirection.Normalize(); isMoving = true; Destroy(gameObject, 0.3f); } // 子弹方向 void Update() { if (isMoving) { transform.position += (Vector3)moveDirection * speed * Time.deltaTime; moveDistance -= speed * Time.deltaTime; if (moveDistance <= 0f) { isMoving = false; Destroy(gameObject); } } } }优化不和特定标签物品发生碰撞

你可以使用Physics2D.IgnoreLayerCollision函数来忽略与特定标签物品的碰撞。首先，你需要在Project Settings -> Physics2D中设置相应的层。然后，在Blogs脚本中，在Start函数中添加以下代码：

int bulletLayer = LayerMask.NameToLayer("Bullet"); // 替换成你自己设置的层名
int ignoreLayer = LayerMask.NameToLayer("IgnoreCollision"); // 替换成你自己设置的层名
Physics2D.IgnoreLayerCollision(bulletLayer, ignoreLayer);

这将使层为"Bullet"的物体忽略与层为"IgnoreCollision"的物体的碰撞。请确保将忽略碰撞的层名替换成你在Project Settings中设置的实际层名。
