This file defines the actual spawn point indicators that appear on the map,
i.e. the icons the player chooses to select his spawn location. If there are 3
groups in this file then there will be a total of 3 available spawn location
on the map. For example, Wake Island has 3 different groups for CTF mode, one
is for the Axis base, one is for the Allied base and the other is for the
main airbase. In total, CTF has 3 different icons available if all spawn points
are active and you count both sides. If you look at the Conquest files you will
notice there are 5, which matches the number of island spawns on the map.
Bear in mind that some vehicles have their own spawn points set up in the
GlobalSpawnGroups.con file located in the bf1942/game folder. This is why in
Conquest mode there are often more spawns, due to those on the ships, troop
carriers, etc.
The spawn point selection icon appears in the center of all the spawn points
using this group number. This can give problems if you attempt to add two aircraft
carriers to the same side, as the spawn location will be between the two. To make
this case work correctly, you need to make a second aircraft carrier with different
spawn point settings in GlobalSpawnGroups.con.
