Lua COMBAT_FORMULA_LEVELMAGIC whats the one based on skills?

[Nevalopo]

Hi! I have now read about COMBAT_FORMULA_LEVELMAGIC which i understand is only based on minmax and level and magiclevel, What do i use if i want it to be based on a single skill like fist fighting?

COMBAT_FORMULA_SKILL ??

Is there any explanation of how i use this to either get max skill or a specific skill based on ?

Yes, it's COMBAT_FORMULA_SKILL, you can find constant names in data/lib/000-constant.lua

You can also use a callback, like this it's more easy to calculate and you can add other things aswell.
Example default TFS 0.3.6 berserk spell

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatParam(combat, COMBAT_PARAM_USECHARGES, true)

local area = createCombatArea(AREA_SQUARE1X1)
setCombatArea(combat, area)

function onGetFormulaValues(cid, level, skill, attack, factor)
     local skillTotal, levelTotal = skill + attack, level / 5
     return -(skillTotal * 0.5 + levelTotal), -(skillTotal * 1.5 + levelTotal)
end

setCombatCallback(combat, CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")

function onCastSpell(cid, var)
     return doCombat(cid, combat, var)
end

end

Ahh i see if i use this formula how does it work?

local skillTotal, levelTotal = skill + attack * 2, level / 5
return -(skillTotal * 2.1 + levelTotal), -(skillTotal * 3 + levelTotal)

what does skill + attack * 2, level / 5 mean? If one have 100 skill and 100 attack on weapon it would do and are level 100 it would deal 420 damage with that formula there? Its so weird that i have to set the fomula twice Why wouldnt
return -(skillTotal + levelTotal) work?

It's the minimum and maximum attack, first one is minimum, second max.
With skill, attack and level all 100 it will deal 420 damage if you do it like this: (skill + attack) * 2 + level / 5
