Entities in OFP are handled, in multiplayer, by one computer alone, which sends updates about this entity to other computers connected to the MP game. A unit is said "local" when it is handled by the local computer.
To know if a unit is local, use the local script command.
The basic rules to determine locality are as follows:
- Player's character is of course local to player's PC
- AI units in a group whose leader is player are local to player's PC.
- All other AI units are local to server (may be player's PC, of course).
- Vehicle is always local where the driver is local
Knowing locality of a unit is very important as certain command only affect local units (see moveInDriver for example). Other commands have only local effect, nothing will be done outside of computer where the command was issued (see setFog for example).
A unit can change locality during its lifetime. Typical cases are a player dying (his squad AI units are passed to server), use of a join command, or units or players entering or exiting vehicles.
