TFS 1.X+ Custom Monster Spell: Instant Damage + Condition

[krafttomten]

Hello OTland!

Does anyone know how to write a custom monster spell in lua that both adds a certain condition, let's say decrease shield skill, and also does instant damage? There are no such monster spells in the original distro that I could find by looking through all of them. And all of my tests have resulted in the monster shooting the spell so fast that the server crashes

This is my code

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_DEATHDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_MORTAREA)
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_DEATH)
combat:setArea(createCombatArea(AREA_BEAM1))

local parameters = {
    {key = CONDITION_PARAM_TICKS, value = 10 * 1000},
    {key = CONDITION_PARAM_SKILL_SHIELDPERCENT, value = 60},
}

function onCastSpell(creature, variant)
    for _, target in ipairs(combat:getTargets(creature, variant)) do
        target:addAttributeCondition(parameters)
    end
    return true
end

Just execute combat after line 14?

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_DEATHDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_MORTAREA)
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_DEATH)
combat:setArea(createCombatArea(AREA_BEAM1))

local parameters = {
    {key = CONDITION_PARAM_TICKS, value = 10 * 1000},
    {key = CONDITION_PARAM_SKILL_SHIELDPERCENT, value = 60},
}

function onCastSpell(creature, variant)
    for _, target in ipairs(combat:getTargets(creature, variant)) do
        target:addAttributeCondition(parameters)
        combat:execute(creature, variant)
    end
    return true
end

Like so? It causes server to crash. And I have not added any damage to the spell either, and don't know how to..

execute the combat after the for loop

Oh yea, it worked! Still no damage, but I found COMBAT_FORMULA_DAMAGE in the src files. Now everything works. Ty for the help Boy67

local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_DEATHDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_MORTAREA)
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_DEATH)
combat:setFormula(COMBAT_FORMULA_DAMAGE, -10, -50)
combat:setArea(createCombatArea(AREA_BEAM1))


local parameters = {
    {key = CONDITION_PARAM_TICKS, value = 10 * 1000},
    {key = CONDITION_PARAM_SKILL_SHIELDPERCENT, value = 60}
}


function onCastSpell(creature, variant)
    for _, target in ipairs(combat:getTargets(creature, variant)) do
        target:addAttributeCondition(parameters)
    end
    combat:execute(creature, variant)
    return true
end
