Alef/JIP – User

General

The server is already running a mission. At least has the mission.sqm processed. Instanced of object/vehicles are in the server address space.

Now, the JIP needs to download from the server the status and keep it updated.

mission.sqm can't be processed like the server does, because of the randomness of units/vehicles. What if server creates and object and the client not, or if the position is different? This should be an easy remember thing.

Client get data from server. Sickboy's page explains that.
