pawn Код:

stock IsValidSkin(SkinID)
{
    if((SkinID == 0)||(SkinID == 7)||(SkinID >= 9 && SkinID <= 41)||(SkinID >= 43 && SkinID <= 64)||(SkinID >= 66 && SkinID <= 73)||(SkinID >= 75 && SkinID <= 85)||(SkinID >= 87 && SkinID <= 118)||(SkinID >= 120 && SkinID <= 148)||(SkinID >= 150 && SkinID <= 207)||(SkinID >= 209 && SkinID <= 264)||(SkinID >= 274 && SkinID <= 288)||(SkinID >= 290 && SkinID <= 299)) return true;
    else return false;
}

pawn Код:

if(!IsValidSkin(SkinID)) return SendClientMessage(playerid, 0xFF030DAA, "Invalid Skin ID");
