Question

我有一个简单的脚本（请不要说明我没有使用switch语句或更好的代码，这是最早的版本，并且由同行以这种方式编写，我正在改进它）需要一个对象并来回移动它。由于某种原因，变量time停留在249.这可能是一个明显的错误，这个低效的逻辑，但我似乎无法找到它。

var speed = 1;
private var time = 0;

function Start() {
}

function Update() {
    if(condition == true)moveStuff();
}

function moveStuff() {
    var timeSwitch = false;
    if(time == 0)timeSwitch = false;
    if(time == timeSet)timeSwitch = true;

        if(direction == 1) {
            if(timeSwitch == false) {
                    transform.Translate(Vector3.up * (Time.deltaTime * speed));
                    time += 1;
                    Debug.Log(time);
                }else if(timeSwitch == true) {
                    transform.Translate(Vector3.up * ((Time.deltaTime * speed) * -1));
                    time -= 1;
                    Debug.Log(time);
                }   
            } else if(direction == 2) {
            if(timeSwitch == false) {
                    transform.Translate(Vector3.down * (Time.deltaTime * speed));
                    time += 1;
                    Debug.Log("Moved down. ");
                }else if(timeSwitch == true){
                    transform.Translate(Vector3.down * ((Time.deltaTime * speed) * -1));
                    time -= 1;
                }
            } else if(direction == 3) {
                if(timeSwitch == false) {
                    transform.Translate(Vector3.forward * (Time.deltaTime * speed));
                    time += 1;
                    Debug.Log("Moved forward. ");
                }else if(timeSwitch == true){
                    transform.Translate(Vector3.forward * ((Time.deltaTime * speed) * -1));
                    time -= 1;
                }
            } else if(direction == 4) {
                if(timeSwitch == false) {
                    transform.Translate(Vector3.back * (Time.deltaTime * speed));
                    time += 1;
                    Debug.Log("Moved back. ");
                }else if(timeSwitch == true){
                    transform.Translate(Vector3.back * ((Time.deltaTime * speed) * -1));
                    time -= 1;
                }
            } else if(direction == 5) {
                if(timeSwitch == false) {
                    transform.Translate(Vector3.right * (Time.deltaTime * speed));
                    time += 1;
                    Debug.Log("Moved right. ");
                }else if(timeSwitch == true){
                    transform.Translate(Vector3.right * ((Time.deltaTime * speed) * -1));
                    time -= 1;
                }
            } else if(direction == 6) {
                if(timeSwitch == false) {
                    transform.Translate(Vector3.left * (Time.deltaTime * speed));
                    time += 1;
                    Debug.Log("Moved left. ");
                }else if(timeSwitch == true){
                    transform.Translate(Vector3.left * ((Time.deltaTime * speed) * -1));
                    time -= 1;
                }
            }
}

我每次在timeSet开始时都将变量moveStuff()声明为false。我把它作为一个私有变量移动到我宣布其他东西的区域，它完美地工作。

Unity JS - 简单的if语句表现不如预期？
