Jiskuha attacks G for 25 damage
G attacks Jiskuha for -20 damage


mob/Enemies
    Click(mob/M)
        if(src in view(1))
            var/damage=Strength+Experience/Luck+Agility*Dexterity
            view()<<"[usr] attacks [src] for [damage] damage"
            src.Strength-=damage
            var/edamage=src.Strength*src.Agility
            view()<<"[src] attacks [usr] for [edamage] damage"
            usr.Strength-=edamage
    G
        icon='G.dmi'
        density=1
        Strength=15
        Agility=2


See the problem? 15*2 is 30, Why in gods name is it displaying -20?

Okay, your subtracting the strength by the damage. So src.strength = 4; src.strength-=damage;damage=5; strength=-1

4-5 becomes negative. 5-4 is positive.

Or in terms of what he's got there:

Strength = 15

Damage = 25 (notice you use the strength var there)

strength -= Damage (you decide to subtract 25 from strength(15-25), so strength = -10)

Edamage - strength(-10) * 2

G will atack for -20.

Just a question here: The luckier you are, the less damage you inflict?

Perhaps luck is inverse. If you're normal (say, 5 luck), you get some reduction in damage. If you're lucky (say, 2 luck), your reduction is much less. If you're cursed (9 luck!), your damage reduction is crippling.

Yes, PirateHead is correct on this subject. Thats how my system is setup. High number = bad, Low = Good. In luck, anyways.

Funny way to calculate it, but ok. What's the range of the stats?

The solution is rather simple, I believe.
finalDamage = max(round(damage, 1), 0)

Make that '0' a '1', and they will always inflict at least one in damage.

Brackets. It's evaluating like this, I bet:

Strength + (Experience / Luck) + (Agility * Dexterity)


Its strength is -10 when it attacks back.

Furthermore, you want to usr usr in the damage calculation.

Division and multiplication have higher precedence than addition and subtraction, so that's not it. Brackets are redundant in this case.
