Circleus has all available options for you listed here:
project overview: https://github.com/zWolfi/INS_Sandstorm
;Allow bot to show up with vehicle
if you want the ammo car and the truck to drive around, use bUseVehicleInsertion=True and set PreRoundTime=0
this way the cars spawn, but the ai models who drive them will not. they spawn at 0.3s
now you can drive them around...
to prevent the lost rounds at map loading, set the GameStartingIntermissionTime=x to at least 20... (this may vary depending on the server, try around a lttle until the lost rounds are gone)
ammo boxes work with the following hc config in the normal checkpoint section.
It's a little bugged tho, sometimes the boxes don't appear or the Ammo Cache on the final objective isn't visible... But you can still resupply where it should be... (press m and then save loadout will resupply)
;Ammobox spawn chance 1.0 = 100%
MOTD is not available in the server options (but asked for since day 1) and only possible via 3rd party tools that use RCON...
http://cassandra.confluvium.info/sissm/ (binaries download available)
you can use the greetings plugin to show repeating messages or only use the welcome message...(config starts line 229)
SISSM also has some very cool additional features...
and when I mention Circleus github and Schroeders SISSM, I also have to mention Ferrets SAW. Great Webadmin tool...
