Well... here I go...
freezeplayer [playername/node]
Freeze/unfreeze a player by his node or name. Works only coop mode and Server or Game Admin only.
A frozen player can't move in x,y,z-axis until server unfreezes him; but he can rotate and use say command. If a player has been frozen in midair (e.g. jumping), player won't fall when server unfreezes him, so it'd work like a pause.
Think: You're the server, you've opened a netgame and earned some players, then you say:
<Server> Nobody complete the level until everyone has arrived at end level!!!
But... someone hurries up and is getting close to endlevel, and no token found. So you use freezeplayer command to stop that hurried player until everyone else can complete the level together.
tunes [zero, slot or default]
Works like current tunes command: you type a slot, the current song is changed. But, let's suppose you want default song come back, but you don't know the slotnumber. So you could type:
tunes default or tunes -1
The default song of level comes back, so you no longer need to know all slots for every levels as before.
seeip [playername/node]
If a player just got out to scape from a ban, you'll be able to his IP though, then you can ban his IP so that he can't get into your netgame again. Server or Game Admin only.
