Made my own spell but no dmg.

local combat0_Brush = createCombatObject()
setCombatParam(combat0_Brush, COMBAT_PARAM_EFFECT, CONST_ME_STUN)
setCombatParam(combat0_Brush, COMBAT_PARAM_TYPE, COMBAT_HOLYDAMAGE)
setCombatArea(combat0_Brush,createCombatArea({{0, 0, 0, 1, 0, 0, 0},
{0, 0, 1, 1, 1, 0, 0},
{0, 1, 1, 1, 1, 1, 0},
{1, 1, 1, 2, 1, 1, 1},
{0, 1, 1, 1, 1, 1, 0},
{0, 0, 1, 1, 1, 0, 0},
{0, 0, 0, 1, 0, 0, 0}}))
setCombatFormula(combat0_Brush, COMBAT_FORMULA_LEVELMAGIC, 3, 5, 7, 10)

-- =============== CORE FUNCTIONS ===============
local function RunPart(c,cid,var,dirList,dirEmitPos) -- Part
if (isCreature(cid)) then
doCombat(cid, c, var)
if (dirList ~= nil) then -- Emit distance effects
local i = 2;
while (i < #dirList) do
doSendDistanceShoot(dirEmitPos,{x=dirEmitPos.x-dirList,y=dirEmitPos.y-dirList[i+1],z=dirEmitPos.z},dirList[1])
i = i + 2
end
end
end
end

function onCastSpell(cid, var)
local startPos = getCreaturePosition(cid)
RunPart(combat0_Brush,cid,var)
return true
end

thats the script.lua i use got the script info from spellcreator but. where and how do i add the dmg formula for the spell?

Kind regards
