LibGDX-加速度计问题

Question

I got some issues. I'm using LibGDX.

1. When I hit an object, my Fighter is supposed to fall to the Ground. BUT, because of the Accelerometer, i can still move it up and down eventhough it died. The Scroller on the x-Axis though stops. Question: (FIXED) How can i make the Accelerometer stop, after Ive been hit, and make the Fighter accelerate to the ground (in absence of the accelerometer, all by itself) ?

2. When I move the Fighter up and down, the transition from "moving up" to "moving down" isnt smooth. It seems like it laggs. Question: How can I Increase the Sensitivity of my Accelerometer?

3. Also, When I tilt the Phone further, the velocity stay the same. Question: How can i increase the velocity, in relation to the tilt degree ?

Thank You !

The Codes are Below:

Accelerometer Code:

       float accelY = Gdx.input.getAccelerometerY();



      if (Gdx.input.getAccelerometerY() < 5){
         velocity.y = -40;
      }


      if (Gdx.input.getAccelerometerY() > 5){
         velocity.y = 40;
      }

When Fighter hits an Object and dies:

              public void die() {
      isAlive = false;
      velocity.y = 0;
      acceleration.y = 460;
   }

Answer 1

You Need to wrap the accel. function with the Alive variable

if(isAlive)
{
    if (Gdx.input.getAccelerometerY() < 5)
    {
        velocity.y = -40;
    }

    if (Gdx.input.getAccelerometerY() > 5)
    {
        velocity.y = 40;
    }
}

Answer 2

For Q2,

if (Gdx.input.getAccelerometerY() < 5){
    velocity.y = -40;
}


if (Gdx.input.getAccelerometerY() > 5){
    velocity.y = 40;
}

The reason it's not smooth is because you did not interpolate the movement. One workaround is:

if (Math.abs(Gdx.input.getAccelerometerY()) > 5){
    YFactor = Gdx.input.getAccelerometerY();
}

//somewhere in your game loop

if(YFactor >0)
{
    if(velocity.y) < YFactor*8{ //tweak this value
        velocity.y += YFactor; //tweak this value
    }
}
else
{
    //reverse above logic
}

What this does is that it will keep - the velocity or +, up until YFactor * 8 (which is what your Q3 needs)

This is just an introduction of concept, you'll need to handle the scope of the variables.
