Work in progress

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. However,OFPEC says mission.sqm/init fields are executed too.

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

So what's happened?

ok, as we enter, player is null. so just waitUntil{!(isNull player)}, like XEH does.

  • name p = Roberto Duarte
  • name player = Error: No vehicle

name of unit p is the random created. No setIdentity in the mission: it would work looking in description.ext/CfgIdentities.
"name player" says there is no vehicle for it, because player is still null.

  • local p ; local player ;
  • isPlayer p ; isPlayer player ;
  • name p = alef (2) ; name player = alef (2) ;

Now the name of unit p has been assigned to the player's name. p is player, I suppose is just a check on the player pointer.

XEH relevant code for JIP:

waitUntil{!(isNull player)}
waitUntil{local player}
