实现坦克的攻击

using UnityEngine;
using System.Collections;
/// 

/// 坦克的攻击
/// 
public class TankAttack : MonoBehaviour
public GameObject shellPrefab;//子弹预制体
    public KeyCode fireKey = KeyCode.Space;//坦克攻击按键
    public float shellSpeed = 10;//子弹速度
    public AudioClip shotAudio;//坦克攻击音效
    private Transform firePosition;
    
 // Use this for initialization
 void Start ()
    {
        firePosition = transform.Find("FirePosition");
    }
    // Update is called once per frame
 void Update () {
        if (Input.GetKeyDown(fireKey))//当按下空格键调用子弹预制体
        {
            //播放坦克攻击音效
            AudioSource.PlayClipAtPoint(shotAudio,transform.position);
            GameObject go = GameObject.Instantiate(shellPrefab, firePosition.position, firePosition.rotation)as GameObject;
            go.GetComponent().velocity = go.transform.forward * shellSpeed;
        }
 }
