java - libGDX actor 在运动时不会表现得正确

Question

我试图让 Actor 每 X 秒随机移动一次。 act的代码是这样的:

@Override
public void act(float delta)
{
    super.act(delta);

    if (delta > (float)(rand.nextInt(5)+3))
    {
        switch(rand.nextInt(3))
        {
            case 0:
                moveBy(3,0);
                break;
            case 1:
                moveBy(-3,0);
                break;
            case 2:
                moveBy(0,3);
                break;
            case 3:
                moveBy(0,-3);
                break;
        }
    }

}

调试仅显示 X 增加的超时时间，并在 ~103 处停止。问题可能是什么？Random 在构造函数中使用 System.currentTimeMillis() 种子进行初始化。

您好，抱歉我的英语测试是这个简单的示例，如果您愿意，请更改最终变量进行调整。

private Random random= new Random();

private float inttt = 0;

private float tiempo = 0;

private int randomT = 0;

private int randomN = 0;

private final int MAXTIEMPO = 15; // cambiar para aumentar o disminuir el tiempo que pasa como maximo entre un movimiento y otro.//changed to increase or decrease the time spent at most from one movement to another.

public int RandomNumber(float delta){

    tiempo += delta;

        if(randomT == 0 || randomN == 0){

                random.setSeed(System.nanoTime() * (long)inttt);
                this.randomN = random.nextInt(MAXTIEMPO);
                inttt += randomN;
                randomT = randomN;

                Gdx.app.log("randomN", ""+randomN);
                Gdx.app.log("randomT", ""+randomT);
                Gdx.app.log("tiempo", ""+tiempo);

                return 0;

        }else if(randomT != 0 && tiempo >= randomT){

                tiempo = 0;
                randomT = 0;

                Gdx.app.log("randomN", ""+randomN);
                Gdx.app.log("randomT", ""+randomT);
                Gdx.app.log("tiempo", ""+tiempo);

                return randomN;

        }else{

                Gdx.app.log("randomN", ""+randomN);
                Gdx.app.log("randomT", ""+randomT);
                Gdx.app.log("tiempo", ""+tiempo);

                return 0;
        }
    }

@覆盖公共(public)无效行为( float 增量){ super.act(delta);

    if (RandomNumber(delta) != 0){

        switch(rand.nextInt(4)){

        case 0:
            moveBy(3,0);
            break;
        case 1:
            moveBy(-3,0);
            break;
        case 2:
            moveBy(0,3);
            break;
        case 3:
            moveBy(0,-3);
            break;
    }
    }
