Damage over time spells

[Faux]

A question for you experts.

When you cast a damage over time spell in Vanguard, did it do immediate damage? Take a necro spell for instance:

Devouring shadows I:

Shadows slowly consume your opponent's life force, dealing #18#1131-1193# damage over 60 sec and transferring half of the life to you.


Unmodified, it does 75-80 damage per tick for 60 seconds. Would you cast that spell and see 75-80 damage immediately or would the damage not start to appear until the first tick interval (4 seconds for necro spells)?

Worded another way, which set of the below intervals would you see damage?

0 4 8 12 16 20 24 28 32 36 40 44 48 52 56

or

4 8 12 16 20 24 28 32 36 40 44 48 52 56 60


The counter example would be:

Sealed Fate I:

Condemns an opponent dealing damage to them in 3 waves. The first wave deals #14#185-197# physical damage instantly, the second deals #14#2184-2300# over 60 sec, and the third deals #14#3550-3736# over 10 minutes.

This DoT specifically states it deals damage immediately and then has 2 separate waves of ticking damage.

No idea about VsH but any MMO I have ever played or pen and paper game the DoT always does the starting tick damage as soon as it is landed. Even progressive curve DoTs worked this way, initial tick was very little damage but then it ramped up.

Yea Ily is right and i know i made a post about that here somewhere. It does a initial tick damage when it lands on the target.

[Faux]

Ok. I play a necro in EQ and it definitely does not work like that, but EQ does synchronized DoT ticks, so all DoTs start on the next tick.

I found a necro video and you guys are right, it does the initial tick immediately.

I gave John a bunch of combat logs, the rogue has lots of DOTS, I imagine looking at those would give you some answers. But I'm pretty sure they did the initial damage as soon as the spell/attack landed and started ticking from there.

Faux, I had a bolt-of-lightning moment about this. Rather than change your Tick start, why don't we just do the initial round of damage for the DoT in the function cast()? I believe that's how I was scripting them anyway, to do the first dot damage, then the tick would take over to finish the rest.

Thats what I am doing John. With a duration of 60 seconds and a frequency of 4 seconds, The ticks run for 15 ticks from 4-60s. The 0s damage is done in cast. And I'm actually using 16 as the number of ticks for damage distribution since we are starting at 0.

I need to get debug working again so that I can find the current crash. I'll send you a PM about it shortly.

[John Adams]

Oh, I think my (new) issue then is that SpellDamage (if in the function cast()) is not generating aggro. Only when the first tick landed did the mob come at me.

[Faux]

I haven't committed that change yet, but it definitely generates agro locally by doing the first tick within the cast function. Need to find the crash before I commit it

[John Adams]

Well this:

Code: Select all

function cast(Caster, dmgType, dmgMin, dmgMax)
    SpellDamage(Caster, dmgType, 0)
end

is not going to do anything. dmgMin of 0 is not going to generate aggro.

When I say do the initial damage in cast, I mean the first mathematical split of the total / frequency, since the start of frequency should be the exact instant of casting (not 4 seconds later).

Code: Select all

function cast(Caster, dmgType, dmgMin, dmgMax)
    dmgMin = math.floor((dmgMin / ticks) + 0.5)
    dmgMax = math.floor((dmgMax / ticks) + 0.5)
    SpellDamage(Caster, dmgType, dmgMin, dmgMax)
end

And, all functions in the Spell Script should be receiving the exact same parameters, regardless of if cast uses "ticks" or not. Not really sure yet why you are passing "ticks" anyway, that should all be in c++ - meaning each min/max damage sent to function tick() should be calculated in code, not in Lua. Lua scripter should just pass SpellDamage(Caster, dmgType, dmgMin, dmgMax) then, without having to do math.
