Unity RayCast, hit ,draw 紅外線碰撞取得資訊

設置紅外線碰撞器，可以使用 RaycastHit底下取得 collider.tag, collider.name , collider.tag 等等等等...
紅外線設置程式碼:
Raycast (位置 : Vector3, 方向 : Vector3, 長度 : float = Mathf.Infinity, 指定碰撞 : int = kDefaultRaycastLayers) : 回傳布林值

本次碰撞視圖:

碰撞程式碼:

using UnityEngine;
using System.Collections;

public class Shoot : MonoBehaviour {
        public Transform Gun;
 void Update () {
  /*Ray Shoot OutBounds*/
  RaycastHit hit;
  Vector3 forward = transform.TransformDirection(Vector3.forward) * 10;
  Debug.DrawRay(Gun.position,Gun.rotation * Vector3.forward * 200,Color.white);
  if(Physics.Raycast(Gun.position,Gun.rotation * Vector3.forward * 200,out hit)){
   if(Input.GetMouseButtonDown(0)){
    print("目標: " + hit.collider.tag);
    Debug.DrawRay(Gun.position,Gun.rotation * Vector3.forward * 200,Color.green);
   }
  }
}

模擬只要碰到目標，按下開槍即取得資訊
