Top of script:

pawn Код:

new cmdstate[MAX_PLAYERS];

Inside your command that makes the player not able to use commands:

pawn Код:

cmdstate[playerid] = 0 // false

OnPlayerConnect and OnPlayerDisconnect:

pawn Код:

cmdstate[playerid] = 1; //True

Under OnPlayerCommandText

pawn Код:

if(cmdstate[playerid] == 0) return 0;

//Then all your other stuff

Hope that helps, it's just a basic array.
