我正在制作一款游戏,如果距离小于2并且敌人面对玩家,则会出现一个带有重新开始选项的文本。在更新中,if和else语句应该检测敌人是否在玩家前面或后面。但是,无论玩家是否面向npc,在距离小于2时似乎总是调用前方选项。
此脚本附加到敌人身上。

// Use this for initialization

player = GameObject.FindGameObjectWithTag ("MainCamera").transform;
//enemy = GameObject.FindGameObjectWithTag ("Enemy").transform;
nav = GetComponent<NavMeshAgent> ();
EnemyCaughtCam.SetActive(false);
SheCaughtYou.text = "";
}
// Update is called once per frame
void Update () {
nav.SetDestination (player.position);
DistanceDeath();

print ("Behind");
else if (npcIsFacingPlayer (player)&& playerIsFacingNpc(player))

DistanceDeath ();

public void DistanceDeath(){
float distance = Vector3.Distance(player.transform.position,
transform.position);
if (distance < 2 ){
EnemyCaughtCam.SetActive(true);
SheCaughtYou.text = "SHE CAUGHT YOU!";
timeTillOptionsMenu -= Time.deltaTime;
if(timeTillOptionsMenu < 0)
{
Restart.SetActive(true);
}

{
Vector3 toOther =
other.position - transform.position;
return (Vector3.Dot(toOther, transform.forward) > 0);

Vector3 toOther =
transform.position - other.position;
