SetTimerEx must be used if you wish to pass arguments (in this case 'playerid') to the timer function:

pawn Код:

SetTimerEx("Unfreeze", 1000, false, "i", playerid);

Also, I recommend calling your functions/variables etc. better names. 'UnfreezePlayer' would be a start. 'Unfreeze' is too vague - unfreeze what? The chicken?
