How do I attach the coordinates of a sprite to its center? LibGDX

Question

I want that when I set a sprite to certain coordinates, it is set to these coordinates by its center.

Answer 1

You can use Sprite.setCenter(x,y)

Sets the position so that the sprite is centered on (x, y)

There's no Sprite.getCenterX() or Sprite.getCenterY() tho. If you need this you can create a class that extends Sprite and implement it your self...

public class MySprite extends Sprite {
    public MySprite(Texture texture) {
        super(texture);
    }

    public float getCenterX(){
        return getX()+getWidth()/2;
    }

    public float getCenterY(){
        return getY()+getHeight()/2;
    }
}

And now use MySprite .

You could also override all position related methods

public class MySprite extends Sprite {
    public MySprite(Texture texture) {
        super(texture);
    }

    @Override
    public void setX(float x) {
        super.setX(x-getWidth()/2);
    }

    @Override
    public void setY(float y) {
        super.setY(y-getHeight()/2);
    }

    @Override
    public void setPosition(float x, float y) {
        super.setPosition(x-getWidth()/2, y-getHeight()/2);
    }

    @Override
    public float getX() {
        return super.getX()+getWidth()/2;
    }

    @Override
    public float getY() {
        return super.getY()+getHeight()/2;
    }
}
