java - Libgdx 加速度计不工作？

Question

出于某种原因，当我倾斜屏幕时，积木没有移动，我不知道出了什么问题。澄清一下，我将 cfg.accelerometer 设置为 true，但将 cfg.compass 设置为 false。这是源代码-

public void update() 
{

    x += velX;
    y += velY;

    //movement

    //left
    if (Gdx.input.isKeyPressed(Keys.LEFT))
    {
        velX = -speed;
    }

    //right
    if (Gdx.input.isKeyPressed(Keys.RIGHT))
    {
        velX = speed;
    }

    //up
    if (Gdx.input.isKeyPressed(Keys.UP))
    {
        velY = -speed;
    }

    //down
    if (Gdx.input.isKeyPressed(Keys.DOWN))
    {
        velY = speed;
    }

    if (Gdx.input.isPeripheralAvailable(Input.Peripheral.Accelerometer))
    {
        velX = Gdx.input.getAccelerometerX();
        velY = Gdx.input.getAccelerometerY();
    }

    //stop
    if (!Gdx.input.isKeyPressed(Keys.LEFT) && !Gdx.input.isKeyPressed(Keys.RIGHT))
    {
        velX = 0;
    }

    if (!Gdx.input.isKeyPressed(Keys.UP) && !Gdx.input.isKeyPressed(Keys.DOWN))
    {
        velY = 0;
    }

    //collision with edges of screen
    if (x <= 0)
    {
        x = 0;
    }

    if (x >= 1920 - width)
    {
        x = 1920 - width;
    }

    if (y <= 0)
    {
        y = 0;
    }

    if (y >= 1080 - height)
    {
        y = 1080 - height;
    }

    long recoveryElapsed = (System.nanoTime() - recoveryTimer)/1000000;
    if (recoveryElapsed > 2000)
    {
        recovering = false;
        recoveryTimer = 0;
    }

    System.out.println(lives+ " lives, recovering, "+recovering);

}

帮助将不胜感激，谢谢。我没有找到显示工作示例的教程，所以我真的不知道我在做什么是否正确，但我看不出有什么问题。

您正在设置加速度值，然后如果没有按下键，您将再次将它们设置为 0。这样做:

//stop
if (!Gdx.input.isKeyPressed(Keys.LEFT) && !Gdx.input.isKeyPressed(Keys.RIGHT))
{
    velX = 0;
}

if (!Gdx.input.isKeyPressed(Keys.UP) && !Gdx.input.isKeyPressed(Keys.DOWN))
{
    velY = 0;
}

if (Gdx.input.isPeripheralAvailable(Input.Peripheral.Accelerometer))
{
    velX = Gdx.input.getAccelerometerX();
    velY = Gdx.input.getAccelerometerY();
}
