It's this line:

pawn Код:

if(!IsSpawned(playerid)) return false;

You are using the function before it's declared below:

pawn Код:

stock bool:IsPlayerHealthHacker(playerid)
{
    if(!IsPlayerConnected(playerid)) return false;
    if(!IsSpawned(playerid)) return false; // used here
//.........

stock bool:IsSpawned(playerid) // created here

Just move it above the other one like so:

pawn Код:

stock bool:IsSpawned(playerid) 
{
//...........
}

stock bool:IsPlayerHealthHacker(playerid)
{
//.........
}
