libgdx touchDown called just once

Question

I\'m new to LibGdx, and have problem with input handling.

My player needs to shoot bullets whenever touch is down. But it seems that this method is called just once.

Answer 1

I have use Continuous Input handle

This is done by setting a flag to your actor eg:

public class Player{
  private boolean firing = false;
  private final Texture texture = new Texture(Gdx.files.internal("data/player.png"));

  public void updateFiring(){
    if (firing){
        // Firing code here
        Gdx.app.log(TAG, "Firing bullets");
    }
  }

  public void setFiring(boolean f){
    this.firing  = f;
  }

  Texture getTexture(){
    return this.texture;
  }

}

Now in my Application class implementing InputProcessor

@Override
public void create() {
    player= new Player();
    batch = new SpriteBatch();
    sprite = new Sprite(player.getTexture());
    Gdx.input.setInputProcessor(this);
}
@Override
public void render() {
    Gdx.gl.glClearColor(1, 1, 1, 1);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

    batch.begin();
    sprite.draw(batch);
    // Update the firing state of the player
    enemyJet.updateFiring();
    batch.end();
}

@Override
public boolean keyDown(int keycode) {
    switch (keycode){
        case Input.Keys.SPACE:
            Gdx.app.log(TAG, "Start firing");
            player.setFiring(true);

    }
    return true;
}

@Override
public boolean keyUp(int keycode) {
    switch (keycode){
        case Input.Keys.SPACE:
            Gdx.app.log(TAG, "Stop firing");
            player.setFiring(false);

    }
    return true;
}

Done
