My Question is how can I move my character faster if a certain button is pressed? I tried it with stepSimulation() from btDynamicsWorld. Also did I set different values but the only result was that the fps dropped dramatically. So which methods can u use to control the movement of the character? I just try to get into android games developement.
You should follow some basic LibGDX tutorials. In any tutorial where you can move a character, find out where the character's x and y coordinates are being set on input. When the "certain button" is pressed, just change the multiplier that affects movement.
For example, in the official tutorial they have this code in the
if(Gdx.input.isKeyPressed(Keys.LEFT)) bucket.x -= 200 * Gdx.graphics.getDeltaTime(); if(Gdx.input.isKeyPressed(Keys.RIGHT)) bucket.x += 200 * Gdx.graphics.getDeltaTime()
Here the multiplier is 200. Change the multiplier and the speed will change.
(If you're just getting started, you should follow some simple tutorials step-by-step, and preferably on desktop because it's easier to work.)
