[henkas]

Hi so i tried to make simple area spell but console gives me warning when i try to run server.

xml

    <instant name="Kiaiho" words="kiaiho" lvl="10" mana="200" prem="0" exhaustion="1000" needlearn="0" event="script" value="LvL10/kiaiho.lua">
    <!-- Goku -->
        <vocation id="1"/>
        <vocation id="5"/>
    </instant>

Lua

local combat1 = createCombatObject()
setCombatParam(combat1, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatFormula(combat1, COMBAT_FORMULA_LEVELMAGIC, -35.0, 0, -55.0, 0)


arr1 = {
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0},
{0, 0, 0, 0, 1, 2, 1, 0, 0, 0, 0},
{0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
}

local area1 = createCombatArea(arr1)

setCombatArea(combat1, area1)


local function onCastSpell1(parameters)
    doCombat(parameters.cid, parameters.combat1, parameters.var)
end

function onCastSpell(cid, var)
local pos1 = {x = getPlayerPosition(cid).x + 1, y = getPlayerPosition(cid).y + 1, z = getPlayerPosition(cid).z}
local parameters = { cid = cid, var = var, combat1 = combat1 }
addEvent(onCastSpell1, 0, parameters)
doSendMagicEffect(pos1, 24)     
return true
end

Where is the problem?

fast answer thanks
P.S sorry guys but i have one more question. So i use this line right>?

local pos1 = {x = getPlayerPosition(cid).x + 2, y = getPlayerPosition(cid).y + 0, z = getPlayerPosition(cid).z}.

But what if i want to change pos with decimal number. Like 2 to 2.5 or what ever how do i have to make it? Because i tried 2.5 but it doesn't change anything

you can't have decimals for positions
you can't take up half a square
