 Unit positions are represented in game by either the structure LOCATION or by passing 2 integers into a function, representing the x and y position. LOCATION represents the tile currently being occupied by the unit. The Outpost 2 game engine requires units to be placed +31 X tiles and -1 Y tiles from their actual position. For example: LOCATION(21 + 31, 15 - 1) would be the position (21,15) on the map.

+===== Vehicle Lights =====
+When any vehicle is created, it defaults to lights off. The function void ''DoSetLights(int boolOn)'' from Unit.h can be used to turn the lights on.
+===== Using the CreateUnit Function =====
+Some variables used in ''CreateUnit'' are not required depending on what unit is being created. For example, a command center cannot have cargo or if you want to create a truck that does not contain any cargo. In these situations use the enum map_id::mapNone to indicate no cargo is required.
+When placing buildings, the variable rotation does not have any meaning and can be set to any value.
