public class cameraFollow : MonoBehaviour

private Vector3 offset;
public float heiht;
private float OffX;
private float offZ;
private void Start()
{
heiht = transform.position.y;
}
private void LateUpdate() //注意點1：相機相關(guān)邏輯存放點
{
if (Tank == null) return; //注意點2：為空判斷
//只有相機的Z軸和X軸跟著Tank變化，y則是距離地面的高度
offset.x = Tank.position.x;
offset.z = Tank.position.z;
offset.y = heiht;
gameObject.transform.position = offset;
}
}
??（D）行為實現(xiàn)——撿起武器發(fā)射炮彈
?????? 步驟：
1.靠近武器，碰撞檢測
2.將武器位置于坦克發(fā)射位置重合
3.武器中封裝了發(fā)射方法
4.發(fā)射方法中封裝了炮彈實例化并且發(fā)射的邏輯

public class BulletMove : MonoBehaviour
{
public GameObject Tank; //掛載在哪個坦克上
public GameObject DeidEffect;
public AudioSource distorySound; //銷毀的音效
private float endTime = 15f; //銷毀倒計時
private void Start()
{
}
//子彈的銷毀及特效
private void OnTriggerEnter(Collider other)
{
if (other.CompareTag("Environment"))
{
if (DeidEffect != null)
{
GameObject eff = Instantiate(DeidEffect, transform.position, transform.rotation);
//音效控制
distorySound = eff.GetComponent<AudioSource>();
distorySound.enabled = MusicContol.SingleMusicContol.nowMusicData.soundSwitch;
distorySound.volume = MusicContol.SingleMusicContol.nowMusicData.soundRoll;
eff.AddComponent<SelfDestroy>();
}
Destroy(this.gameObject);
}
}
private void Update()
{
//當(dāng)未碰撞時自動銷毀
endTimeDistory(gameObject);
}
//倒計時銷毀
public void endTimeDistory( GameObject instans)
{
endTime = Mathf.MoveTowards(endTime, 0, 0.1f);
if (endTime <= 0) Destroy(instans);
}
}
總結(jié)：
問題： 為什么炮彈生成了卻無法射出 ; 原因: FreezePosition被鎖定了
問題：往前走時，發(fā)射方向和炮口方向相反
