I'm still thinking, how do I properly pool a bullet in libgdx ashley? Because the PooledEngine is available, which the Entities, Components and Systems are already Pooled. I made this below example, which I just create a builder-pattern to spawn a bullet. Without using the ashley ECS framework, I used this memory-management reference to create a bullet pool as result this made me more confused.
class EntityFactory { ... public EntityFactory(World world, PooledEngine engine) { this.engine = engine; this.world = world; } public Entity createBullet(float x, float y) { ... } } class GunSystem extends IteratingSystem { EntityFactory factory; public GunSystem(EntityFactory factory) { super(Mappers.gunFamily); this.factory = factory; } @Override public void processEntity(Entity entity, float deltaTime) { GunComponent gun = Mappers.gun.get(entity); NodeComponent node = Mappers.node.get(entity); float bulletX = ...; float bulletY = ...; if(gun.reload) { Entity bullet = factory.createBullet(bulletX, bulletY); node.putChild("bullet", bullet); } if(gun.fire) { Entity bullet = node.getChild("bullet"); ... move body to target destination BulletComponent b b.state.fired = true; node.removeChild("bullet"); } } } Question what do you think is the proper way of creating bullet pool in ashley ecs framework?
