When "entity" is added to "gameword", the "component" of "entity" is initialized once.

When "Entity" is added to "GameWord", the "Component" of "Entity" is initialized once.
Because some components need to add "Entity" to "GameWord" before they can be fully initialized.
For example：

    @Spawns(PLAYER)
    public Entity newPlayer(SpawnData data) {
        var texture = texture("player.png");
        return entityBuilder(data)
                .type(EntityType.PLAYER)
                .at(getAppWidth() / 2 - texture.getWidth() / 2, getAppHeight() / 2 - texture.getHeight() / 2)
                .viewWithBBox(texture)
                .collidable()
                .with(new TopDownMoveComponent(200).collidables(WALL))
                .build();
    }

This causes "NullPointException", because "colladables" requires "GameWord",but it is obvious that "Entity" has not been added to "GameWord" now.

The following code can solve the problem, but I prefer "component" to complete the whole function, which can reduce the coupling.

entity.setOnActive(()->topDownMoveComponent.collidables(WALL));
