Called when an entity is being removed.

virtual void OnReused(IEntity * pEntity, SEntitySpawnParams & params) = 0;

virtual void OnSpawn(IEntity * pEntity, SEntitySpawnParams & params) = 0;

This callback is called when this entity has finished spawning. The entity has been created and added to the list of entities, but has not been initialized yet.
