Lua [TFS 1.2] monster use spell only if it is at a distance > 1 from target

[gtms]

Have this spell for example:

Spoiler: energy strike

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_ENERGYAREA)
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGY)


function onCastSpell(creature, variant)
-- if creature:distance from target > 1 then
return combat:execute(creature, variant)
--end
end

someone knows how to check the distance between the creature and the target?

thanks

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_ENERGYAREA)
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGY)


function onCastSpell(creature, variant)
    variant_uid = variant:toNumber()
    target = Creature(variant_uid)
    t_pos = target:getPosition()
 
    --If the variant is too far away--
    if creature:getPosition():getDistance(t_pos) > 1 then
        return false
    end

    return combat:execute(creature, variant)
end

had to use target = Creature(variant.number)

works perfectly, thanks!
