17:44Spec out gen_room_connection as a linked list of connections to a single room

20:04Spec out gen_connection itself as a linked list of its two connected rooms, with gen_room_connection as a linked list of these connections

22:10Implement this more verbose version, introducing AddConnection() for Connect() to call, and making GenRoom() link up the rooms

28:46Implement GenerateWorld(), and GenerateRoom() to do the old work of AddStandardRoom()

41:31Make GenerateRoom() call BeginWorldChange() and EndWorldChange(), and begin to systematise the entity system inside the world generator working off a sim_region, respecifying BeginEntity() and EndEntity() as AddEntity() and PlaceEntity()

58:52Relieve EndSim() and EndWorldChange() of taking the World, and create handmade_room_gen.cpp

1:03:34Pull the entity creation code from handmade_world_gen.cpp into handmade_room_gen.cpp

1:06:24Add TempMemory to the world_generator struct for GenerateRoom() to use, and setup the room's position and dimensions for entity simulation purposes

1:15:45Enable AddPlayer() to create a player entity, calling AddEntity() directly on the SimRegion

1:19:10Implement Layout(), initially stamping down rooms in a row

1:25:43Make CreateWorld() initialise the camera position, introducing gen_result struct
