pawn Код:

//global
new enableCmd[MAX_PLAYERS]; //the toggle variable for us to use

pawn Код:

//OnPlayerEnterCheckpoint
enableCmd[playerid] = 1; //make it possible for player to use the command if he enters the checkpoint

pawn Код:

//OnPlayerExitCheckpoint
enableCmd[playerid] = 0; //make it impossible for player to use the command if he leaves the checkpoint

pawn Код:

//OnPlayerText
if(enableCmd[playerid] && IsPlayerInCheckpoint(playerid))
{
    if(!strcmp(text, "1", true))
    {

    }
    //continue making for the other numbers
}
