Add this to the top of your script.

pawn Код:

new isdmgsniper[MAX_PLAYERS]=0;

Then:

pawn Код:

public OnPlayerSpawn(playerid)
{
         new skinid = GetPlayerSkin(playerid);
         if(skinid==17)
         {
             isdmgsniper[playerid]=1;
         }
         else isdmgsniper[playerid]=0;
   return 1;
}

Add this above the line (if issuerid....)

pawn Код:

if (isdmgsniper[playerid]==1)

So now, if player chooses skin:

his one sniper hit will result in a 100 pcnt health loss, or for other skins, it wont.
