Lua Directional Spell & addEvent issue

[Xikini]

TFS 1.4.2

I want the direction of the spell to remain static. So if I'm facing south and cast, it will cast south 3 times, in the original casted spot.

So this works as expected, until I start moving my character around. xD

It seems like the direction of the character is checked everytime combat is called.. and there's no way to give the spell any information to get around that.

Is there something simple I'm missing?

local combat1 = Combat()
combat1:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
combat1:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGY)
combat1:setArea(createCombatArea(AREA_SQUAREWAVE5, AREADIAGONAL_SQUAREWAVE5))

local combat2 = Combat()
combat2:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_RED)
combat2:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_FIRE)
combat2:setArea(createCombatArea(AREA_SQUAREWAVE5, AREADIAGONAL_SQUAREWAVE5))

local combat3 = Combat()
combat3:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_GREEN)
combat3:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_POISON)
combat3:setArea(createCombatArea(AREA_SQUAREWAVE5, AREADIAGONAL_SQUAREWAVE5))


local function castDelayedSpell(creatureId, variant, combat)
    local creature = Creature(creatureId)
    if not creature then
        return
    end
    combat:execute(creature, variant)
end

local spell = Spell("instant")

function spell.onCastSpell(creature, variant)
    local creatureId = creature:getId()
    addEvent(castDelayedSpell, 0, creatureId, variant, combat1)
    addEvent(castDelayedSpell, 500, creatureId, variant, combat2)
    addEvent(castDelayedSpell, 1000, creatureId, variant, combat3)
    return 
end

spell:name("triple effect spell")
spell:words("triple effect spell")

You can generate the positions first and then do a 3x loop (with addEvents) and using doTargetCombat

local combat = Combat()
combat:setArea(createCombatArea(AREA_SQUAREWAVE5, AREADIAGONAL_SQUAREWAVE5))

local spell = Spell("instant")
function spell.onCastSpell(creature, variant)

    local positions = combat:getPositions(creature, variant) -- # array
    -- # your code
 
    return
end

Nice.
This should work. Give me a few minutes to give it a try.

Thanks for that. xD
Life jumped up and I wasn't able to try it out as quick as I wanted to.
