I wondered why when I set ge_roundtime 0 the map ended surely 0 means infinite?
You have 2 cvars that control the amount of time rounds last
ge_roundtime
mp_timelimit
I think only time they conflict is when you want an infinate time you ahve to set bot the zero.
Maybe some pictures will help explain, it's late and I am tired.
Used the "timeleft" command( bind it to a key)
Ge_roundtime 0
But wait...
And why do it in seconds?
