DynamicBody останавливается на StaticBody при езде со скоростью

Question

Я создаю приложение на LibGDX с Box2D , и когда я даю скорость body(dynamic) и устанавливаю трение на 0, но тело останавливается во время езды на платформе,Как мне решить эту проблему?

Я пытался изменить трение или скорость тела, а также изменить положение блоков на платформе (сделать их ближе друг к другу).

public class Block extends Sprite {
    public Fixture fixture;

    public Block(Texture texture, Fixture fixture){
        this.fixture = fixture;

        setTexture(texture);
        setRegion(texture);
        setBounds(fixture.getBody().getPosition().x,fixture.getBody().getPosition().y,texture.getWidth()/ Var.PPM, texture.getHeight()/ Var.PPM);
    }

    static public class BlockType{
        public static final Texture GRASS = new Texture("grass.png");
        public static final Texture GROUND = new Texture("ground.png");
    }
}

Итак, я увеличил камеру и вижу один пиксель, который останавливает мое тело.
