Lua TFS 1.3 spell question

[Mjmackan]

Is there any way you can randomize the spell area for each time casting an spell?

For example I have 3 areas setup like this:

local area = {
{
    {1, 1, 1},
    {1, 3, 1},
    {1, 1, 1}
},{
    {0, 0, 0},
    {0, 3, 0},
    {0, 0, 0}
},{
    {1, 1, 1, 1, 1},
    {1, 1, 1, 1, 1},
    {1, 1, 3, 1 ,1},
    {1, 1, 1, 1, 1},
    {1, 1, 1, 1, 1}
}}

And i want to randomize between these 3, i tried using: (and a lot others)

combat:setArea(createCombatArea(area[math.random(1,3)]))

But since that only combat type will load during start, it will always throw the same area.

To make it even more complicated, this is actually a weapon script, so the statements Ive done might actually not be true for spells.

I believe that this portion of the spell needs to be set during server startUp, so it's impossible to randomise the area.

However.. if you created 3 identical 'combats'
aka, combat1, combat2, combat3

You could randomise the combat that is used, and would achieve the same result.

Thats how i did it with a spell, but it looks so messy, thanks however for letting me know.

I mean, I might be wrong since I've never tried with tfs 1.0+, but you can test if you want.

Spoiler: didn't work

Here's how I'd try it.

local areas = {
    {
        {1, 1, 1},
        {1, 3, 1},
        {1, 1, 1}
    },
    {
        {0, 0, 0},
        {0, 3, 0},
        {0, 0, 0}
    },
    {
        {1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1},
        {1, 1, 3, 1 ,1},
        {1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1}
    }
}



function onCast(blah blah)
  
    -- actual important part. lol
    local rand = math.random(#areas)
    combat:setArea(createCombatArea(areas[rand]))

    return combat:blah blah blah
end

-- Edit

Yeah, it just doesn't work.
Have to do the 'messy' 3 combats method.

local areas = {AREA_SQUARE1X1, AREA_CIRCLE3X3}
local combats = {}

for i = 1, #areas, 1 do
    local combat = Combat()
    combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_HOLYDAMAGE)
    combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_HOLYAREA)
    combat:setArea(createCombatArea(areas[i]))
    function onGetFormulaValues(player, level, magicLevel)
        local min = (level / 5) + (magicLevel * 5) + 25
        local max = (level / 5) + (magicLevel * 6.2) + 45
        return -min, -max
    end
    combat:setCallback(CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")
    table.insert(combats, #combats + 1, combat)
end

function onCastSpell(creature, variant)
    return combats[math.random(1, #combats)]:execute(creature, variant)
end

Ofcourse, you can do like that, clever. I went with the messy method however, the math.random is a really good tool to specify chances etc.
