子弹变成弹孔

Question

在我的项目中，我有枪。我的子弹使用刚体并在我开火时在枪管处产生。我的子弹穿过墙壁反弹，有时它穿过墙壁。

我知道，在物理射线投射中它非常简单：

public GameObject par;
public int damage;

void Update()
{
    RaycastHit hit;
    Ray ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width / 2, Screen.height / 2, 0));

    if (Input.GetMouseButtonDown(0))
    {
        if (Physics.Raycast(ray, out hit, 100))
        {
            GameObject particleClone = Instantiate(par, hit.point, Quaternion.LookRotation(hit.normal)) as GameObject;
            Destroy(particleClone, 2);
            hit.transform.SendMessage("ApplyDamage", damage, SendMessageOptions.DontRequireReceiver);
        }
    }
}

如何在刚体中做到这一点？ Bullet 变成了粒子系统或弹孔图像。

我应该使用OnCollisionEnter() 还是OnTriggerEnter()？

如何使它成为弹孔图像或粒子系统？

Answer 1

OnCollisionEnter 和 OnTriggerEnter 都可以使用；但是，请查看有关差异的解释：What is the difference between OnCollisionEnter and OnTriggerEnter?

Answer 2

我在以下位置找到了这个 JavaScript：RAYCAST, BULLET HOLES, AND RANDOM ARRAYS

你把它添加到你武器的发射器中：

---

var bulletTex : GameObject[]; // creates an array to use random textures of bullet holes

function Update ()
{

   var fwd = transform.TransformDirection(Vector3.forward); //casts our raycast in the forward direction
   var hit : RaycastHit;
   Debug.DrawRay(transform.position, fwd * 10, Color.green); //drays our raycast and gives it a green color and a length of 10 meters

   if(Input.GetButtonDown ("Fire1") && Physics.Raycast(transform.position, fwd, hit, 10))
   { //when we left click and our raycast hits something
         Instantiate(bulletTex[Random.Range(0,3)], hit.point, Quaternion.FromToRotation(Vector3.up, hit.normal)); //then we'll instantiate a random bullet hole texture from our array and apply it where we click and adjust
   // the position and rotation of textures to match the object being hit
   }
}
