Help with spell formula

[lucas mazzotti]

hello guys, can someone help me with converting formula spells? heres the spell:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_HOLYDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HOLYAREA)
setAttackFormula(combat, COMBAT_FORMULA_LEVELMAGIC, 9, 9, 14, 17)
local area = createCombatArea(AREA_CIRCLE3X3)
setCombatArea(combat, area)

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

all i wanna do is changing setAttackFormula(combat, COMBAT_FORMULA_LEVELMAGIC, 9, 9, 14, 17)
for formula min, max
like this:
local min = -((level/5)+(maglevel*10))
local max = -((level/5)+(maglevel*20))

if you ask why, i have an ot and making some balancing stuff, its atual version but with old style damages, and lets say i have some trouble with that kind of formulas, anyways, thanks a lot

Here you are.

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_HOLYDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HOLYAREA)
local area = createCombatArea(AREA_CIRCLE3X3)
setCombatArea(combat, area)

function getCombatFormulas(cid, level, magicLevel)
    local min = -((level/5)+(magicLevel*10))    
    local max = -((level/5)+(magicLevel*20))

    if(max < min) then
        local tmp = max
        max = min
        min = tmp
    end
    return min, max
end

setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "getCombatFormulas")

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

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_HOLYDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HOLYAREA)
local area = createCombatArea(AREA_CIRCLE3X3)
setCombatArea(combat, area)
function getCombatFormulas(cid, level, magicLevel)
    local min = -((level/5)+(magicLevel*10)) 
    local max = -((level/5)+(magicLevel*20))
     -- easier way
    return max < min and max, min or min, max
end
setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "getCombatFormulas")
function onCastSpell(cid, var)
    return doCombat(cid, combat, var)
end

This formula will return an extra value but that extra value will be discarded

return max < min and max, min or min, max

function v()
    a = -1
    b = -2
    return (b < a) and b, a or a, b
end
local min, max = v()

print(min, max)
-- prints -2    -1

Of course if the b is greater than a then it will return false and a, so maybe your way is better

function v()
    a = -3
    b = -1
    return b < a and b, a or a, b
end
local min, max = v()

print(min, max)
-- prints     false     -3
