View source for Scripts:AutoMap

== Introduction ==
With the 16/32/64 player map modes from BF2, I was upset to see that BF2 didn't support dynamic scaling of the map size based on the number of players connected. I went ahead and threw something together to fix this issue. It also randomizes the map cycle. The randomization feature is currently hardcoded into the script.

== What It Does ==

It gets its data from the server maplist file as defined in the server config file, defaulting to <code>mods/bf2/settings/maplist.con</code>, on every <code>[[Object_Reference#bf2.GameStatus|GameStatus.Playing]]</code> event thrown, so you can change it on the fly and invalid maps are still handled by the normal maplist parsing that hapens when bf2 loads up. It also sets the next map on this Event so that attempts to get the next map using 'admin.nextLevel' will succeed. The size of the map, however, is decided on <code>[[Object_Reference#bf2.GameStatus|GameStatus.EndGame]]</code> to ensure that the next map's size is set properly as close to the map change as possible.

== Comments ==

* Currently, if there's only one map in the maplist, a loop will start and never, ever stop. If nobody beats me to it, I'll fix it soon. --[[User:Dst|Dst]] 14:04, 28 Jul 2005 (MDT)

* If someone would be so kind as to make my commented instructions more user-friendly, I'd be very grateful. --[[User:Dst|Dst]] 14:04, 28 Jul 2005 (MDT)
