I've once posted a function called DamagePlayer, but here's the same function which is improved!

pawn Code:

stock DamagePlayer(playerid, Float:damage)
{
    static
        Float:temp_hp,
        Float:temp_ar;
    GetPlayerHealth(playerid, temp_hp);
    GetPlayerArmour(playerid, temp_ar);
    if(temp_ar > 0)
    {
        if(damage > temp_ar)
        {
            SetPlayerArmour(playerid, 0.0);
            SetPlayerHealth(playerid, floatsub(damage, temp_ar));
        }
        else if(damage < temp_ar)
        {
            SetPlayerArmour(playerid, floatsub(temp_ar,damage));
        }
    }
    else if(temp_ar <= 0)
    {
        if(damage > temp_hp)
        {
            SetPlayerHealth(playerid, 0.0);
        }
        else if(damage < temp_hp)
        {
            SetPlayerHealth(playerid, floatsub(temp_hp,damage));
        }
    }
    return 1;
}

This functions damages the player just like in-game normal damage. It reduces the armour in case if player got that and if the damage is higher than the armour, it reduces health too.
