Questions about different ways to move entities.

[samuelwhiskeyjohnson]

METHOD 1 Using onUpdate() in the GameApplication subclass (global)
as seen here

@Override
protected void onUpdate(double tpf) {
    getGameWorld().getEntitiesByType(EntityType.MY_TYPE)
        .forEach(e -> e.translateX(100 * tpf)); // move all entities of this type
}

METHOD 2 Using a Component attached to an entity
as seen here

Entity entity = ...;

entity.addComponent(new Component() {
    @Override
    public void onUpdate(double tpf) {
        entity.translateX(100 * tpf); // moves right 100 px/sec
    }
});

METHOD 3 Using an existing component attached to an entity
as seen here

entityBuilder(data)
                .type(KEY)
                .bbox(new HitBox(BoundingShape.box(45, 58)))
                .view(view)
                .with(
                        new ProjectileComponent(new Point2D(0, 1), random(100, 300))
                                .allowRotation(false)
                )
                .with("keyCode", keyCode)
                .collidable()
                .build();

METHOD 4 Animation builder
as seen here

Entity entity = ...;

Animation<?> anim = animationBuilder()
    .duration(Duration.seconds(3))
    .translate(entity)
    .from(new Point2D(0, 0))
    .to(new Point2D(300, 0))
    .build();

anim.play();

When should I use which?
Are there other ways to move?
How come no games in FXGLGames repo are using animation builder?

Hi, these all have slightly different use cases, but ultimately, they all end up calling TransformComponent and update its x,y,z. Feel free to use what seems the most suitable for your use case.
