子弹实例化墙内,不触发OnCollisionEnter2D

void OnCollisionEnter2D(Collision2D col)
    {
        if (col.gameObject.tag == "Wall")
        {
            Destroy(gameObject);
        }
    }

我使用这个脚本.一切都很好,但是如果我的子弹在Wall中产生,它不会与wall反应.它在墙上飞.
那么,如果它在墙内产生,我应该怎么用来立即销毁子弹？

项目符号生成方法：

Instantiate(bullet1, firepoint1.position, firepoint1.rotation);

因此,首先需要在“图层”中添加“墙”(Here,您可以看到如何创建新图层并将墙分配给该图层).将其作为参数传递给用于实例化项目符号的脚本(例如,坦克的脚本).

public LayerMask wallLayer;

将储罐的变换保存在变量中

// Variable with position of the Tank
Transform _transform;

void Awake () {

    _transform = GetComponent<Transform> ();

}

接下来,您将生成Physics2D.Linecast. Source.假设您使用附在坦克GameObject上的脚本来发射子弹：

// Linecase goes from the tank position to the place where you would be instantiating the bullet
boolean insideWall = Physics2D.Linecast(_transform.position, firepoint1.position, wallLayer);

然后,仅当您不会在墙内实例化子弹时,才实例化子弹.

if(!insideWall)
    Instantiate(bullet1, firepoint1.position, firepoint1.rotation);
