I haven't tested.
cvar mp_join_grace_time have max. value 30 seconds
Code:
"mp_join_grace_time" = "0.0" min. 0.000000 max. 30.000000 game replicated - Number of seconds after round start to allow a player to join a game
But you can remove this cvar upper pound with plugin.
PHP Code:
public void OnPluginStart()
{
ConVar mp_join_grace_time = FindConVar("mp_join_grace_time");
if(mp_join_grace_time != null)
{
mp_join_grace_time.SetBounds(ConVarBound_Upper, false);
}
}
After loading plugin, it should show like this
Code:
mp_join_grace_time
"mp_join_grace_time" = "0.0" min. 0.000000 game replicated - Number of seconds after round start to allow a player to join a game
Then you set in
gamemode_casual_server.cfg your new time, ex.
mp_join_grace_time 1500
