  # it checks for children entities with the "projectile_component", which then handles the projectile logic on their own.
  # This allows for rapid creation and iteration of projectiles, because you can simply place as many child entities within the container entity
  # as you want, and as long as the container has the "projectile_container_component" and the children have the
  # "projectile_component" added, they will handle all gameplay logic
