Start using PVars. They're meant to be used for things like this.

In your command put this at the top:

pawn Код:

if(GetPVarInt(playerid, "IsInDM") == 1)
    return SendClientMessage(playerid, COLOR_RED, "You are already in the DM!");

SetPVarInt(playerid, "IsInDM", 1);
// rest of your code (SetPlayerPos etc)

and whenever the player exits the DM put

pawn Код:

SetPVarInt(playerid, "IsInDM", 0);
// OR
DeletePVar(playerid, "IsInDM");
