Idea

The ObjectManager is the one place, where all the Entitites of the Game are stored. The ObjectManager has multiple lists for Environmentals, enemies, dead and living matter, friends, projectiles and so on.

With the ObjectManager Entities can be grouped, and as such be ticked, drawn and collided independently and much safer, as without it.

Interaction

The ObjectManager works closely together with WorldEntity, as it is a storage container for them.

The ObjectManager has the following Lists, to store Entities:

OM_NULL	Not accessible (where they are created and deleted !! DO NOT USE THIS)
OM_DEAD	Dead Entities, that might be revived
OM_DEAD_TICK	Dead Entities, that must be ticked (e.g to respawn them for instance)
OM_ENVIRON_NOTICK	Environment that is dead matter (ground house…)
OM_ENVIRON	Environment that moved (water, trees, Particles…)
OM_COMMON	Everything that is nowhere else, (collides with all groups)
OM_GROUP_??	Groups, for entitites
OM_GROUP_??_PROJ	Projectiles of the above mentioned groups.

To Put an entity into a corresponding group (and thus taking it out of its previous group) do a:

  WorldEntity* entity = new DoomsDayDevice();
  entity->toList(OM_GROUP_01_PROJ);
