如何控制一台电梯的逻辑LiftTrigger
C#

public float timeToLiftStart = 3f; // 从玩家进入电梯到电梯自动升高的时长.

}

if(other.gameObject == player)
{
// ... 设置playerInLift标志位为false，并且重置计时器.
playerInLift = false;

}
}
//在这个函数中，处理电梯栅栏门的开关状态
//如果玩家还没有进入电梯或者进入电梯后还没有超过电梯门自动关闭时间，这个时候的栅栏门是跟随者外面红色铁皮门的开关而开关
//如果超过了自动关闭时间电梯门就会自己关闭，将玩家关在电梯内部
void Update ()
{
// 如果玩家是否进入到电梯内...
if(playerInLift)
// ... 执行逃生程序.

// 如果计时器现在记录的时长小于关闭时间...
if(timer < timeToDoorsClose)
// ...电梯的栅栏门跟随者外面的铁皮红门的位置移动.
liftDoorsTracking.DoorFollowing();
else
// 电梯的栅栏门自行关闭.
liftDoorsTracking.CloseDoors();
}
void LiftActivation ()
{
// 时间计数器增加.
timer += Time.deltaTime;
// 时间计数器大于了电梯自动升起时间...
if(timer >= timeToLiftStart)
{o
// ... 玩家的移动速度为0，摄像机控制失效，玩家变成电梯的子物体，跟随电梯移动.
playerAnim.SetFloat(hash.speedFloat,0f);
camMovement.enabled = false;
player.transform.parent = transform;
// 电梯向上升起.
transform.Translate(Vector3.up * liftSpeed * Time.deltaTime);
// 如果没有播放声音...
if(!audio.isPlaying)
// ... 播放逃生的音乐文件.
audio.Play();
// 如果时间超过了场景结束时间..
if(timer >= timeToEndLevel)
// ... 场景结束.
sceneFadeInOut.EndScene();
}
}
}
