The variable "id" is a string, and you're using functions that require their parameters to be integers. To get the integer value of a string use

pawn Код:

strval

Rather than having

pawn Код:

IsPlayerConnected(id)

, you should have

pawn Код:

IsPlayerConnect(strval(id))

However. You're using the 'u' parameter in sscanf, and therefore you should merely declared 'id' as an integer (- remove the array's size).
