[SyntaxQ]

I'm not sure if this will work...

pawn Код:

public OnPlayerTakeDamage( playerid, issuerid, Float:amount, weaponid )
{
    new Float:h;
    if (weaponid == 24)
    {
        if (amount >= 50)
        {
            GetPlayerHealth(playerid, h);
            SetPlayerHealth(playerid, h + 25.0);
        }
    }
    return 1;
}

This should increase the health by 25.0 whenever deagle causes more than or equal to 50 damage..
