pawn Код:

stock IsPlayerInWater(playerid)
{
    new animlib[32],tmp[32];
    GetAnimationName(GetPlayerAnimationIndex(playerid),animlib,32,tmp,32);
    if(!strcmp(animlib, "SWIM") && !IsPlayerInAnyVehicle(playerid) ) return true;
    return false;
}

And put this on player update:

pawn Код:

if(IsPlayerInWater(playerid))
        {
            SetPlayerHealth(playerid,0.0);
        }
