How to implement "Gradual pertification"?

[ShiyoKozuki]

The effect exists, and doom has a "counter" tick mechanic in it's effect(gradual petri doesn't have a counter iirc). For gradual petri your character(s) gradually move and attack slower until eventually petrified.

🤔 hmm from a code end its likely not that different to do in the effects onTick if we go that route, we have mods to adjust all of those things and then we can full stop after the right number of ticks. need to know how many ticks it takes and if that is variable.

This status can only be removed by defeating the enemy that inflicted it. Stona and Benediction have no effect.

• Upon the countdown reaching zero, the Gradual Petrification effect is replaced by the negative status effect Petrification. At this point it may now be removed by standard means.

• If a Petrify Screen is used while gradually petrifying, the Negate Petrify status will prevent petrification from taking place immediately when the counter reaches 0; however the Gradual Petrification status will remain and you will become petrified once the Negate Petrify status wears off.

Edit: found a reference on BG that says it is a "20-count period" (confirming clopedia) so either 20 ticks or 20 seconds, and each tick slow movespeed and melee speed a little more.

Q: ranged speed? if its -haste it'd still effect magic casts too but not ra.

Don't think anyone's ever tested it on a ranger, it could be negative snapshot which is easy to code.

[TeoTwawki]

yeah if it does that it'll at least be easy to add

I don't know how to code per ticks properly on effects to do this.

--
--xi.effect.GRADUAL_PETRIFICATION
--
-----------------------------------

effect_object.onEffectGain = function(target, effect)
    -- minimum time is 10 seconds!
    if (effect:getPower() < 10) then
        effect:setPower(10)
    end
end

effect_object.onEffectTick = function(target, effect)
    local remainingTicks = 1 + (effect:getTimeRemaining() / 1000) / 3
end

effect_object.onEffectLose = function(target, effect)
    if (effect:getTimeRemaining() == 0) then
        target:addStatusEffect(xi.effect.PETRIFICATION, 1, 0, 60)
    end
end

return effect_object

On the mob skill...

       local typeEffect = xi.effect.GRADUAL_PETRIFICATION
	MobStatusEffectMove(mob, target, typeEffect, 20, 3, 60)

How do I add the slow/movement speed/snapshot to be per tick too?

pseudo-code, hypothetical:

effect_object.onEffectGain = function(target, effect)
    -- I don't think we need to do anything here at all, if duration and total ticks line up we're good
end

effect_object.onEffectTick = function(target, effect)
    target:addMod(xi.mod.HASTE, effect:getPower()) -- neg. haste per tick here
    target:addMod(xi.mod.MOVESPEED, effect:getSubPower()) -- neg. movespeed per tick here
    effect:setTier(effect:getTier() +1)
end

effect_object.onEffectLose = function(target, effect)
    local tickCount = effect:getTier()
    target:addStatusEffect(xi.effect.PETRIFICATION, 1, 0, 60)
    targetdelMod(xi.mod.HASTE, effect:getPower() * tickCount)
    target:delMod(xi.mod.MOVESPEED, effect:getSubPower() * tickCount)
end

return effect_object
