Hello, I tried to do a script like that:

pawn Code:

public OnPlayerTakeDamage(playerid, issuerid, Float: amount, weaponid)
{
    if(issuerid != INVALID_PLAYER_ID)
    {
        if(IsPlayerRNPC(playerid))
        {
            new string[20];
            new Float:Health;
            GetPlayerHealth(playerid, Health);
            SetPlayerHealth(playerid, Health-10);
            format(string, sizeof(string), "~w~RNPC HEALTH: ~r~%0.2f~w~.", Health);
            GameTextForPlayer(issuerid, string, 2000, 3);
        }
    }
    return 1;
}

But does not it work, how it should be the code really?.
