Problem with fountain's mana regeneration

[mr po]

Warcraft III - Neutral -> Neutral Buildings

Blizzard says the fountain of mana regenerates 1% of total mana per second.
That means it should take 100 seconds to fully regenerate a unit with no mana regeneration.

But when i test it , it takes less than 100 seconds to fully regenerate. Any idea whats going on, or i misunderstood something?

Theoretically speaking, that would be the case. However, there are several factors at play such as innate mana regeneration, initial amount of mana, mana regeneration boosting items, mana draining, etc. All of these factors would play a role in jeopardizing your observations.

Spoiler: A bit of math here

Consider a parabola y = a((x - h)*(x - h)) + k wherein h and k are the abscissa and the ordinate of the vertex of the parabola respectively. Now, for x == h, y = k. The value of y at that moment is k.

Going back to the problem, assume that the amount of mana is 0 at Time Zero, with a regeneration rate of 3 mana per second. At Time One, the amount of mana suddenly goes up to 78, with the regeneration rate having been maintained. At Time Two, the amount of mana becomes 84, with the regeneration rate having gone up to 6 mana per second.

Theoretically speaking, mana at Time Zero would be 0, mana at Time One would be 3, and mana at Time Two would be 6. This theoretical scenario assumes that the rate of change is constant, which it rarely is, if ever.

EDIT:

I looked at the map. Didn't need to test it as the units themselves already had an initial amount of mana.

I refer to units with mana but no initial mana and mana regeneration. So their mana stays 0 mana unless approach the fountain of mana

 

[MyPad]

It could be because of the continuous re-approximation of mana done by the system. Think of interest compounded continuously. Think of it as having different mana regeneration rates per instant.

EDIT:

With what has been said and done, I forgot that the mana regeneration provided by the fountain is hardcoded, that is, the increase in mana regeneration will not happen until after 1 - 2 seconds of being close to the fountain.

 

[mr po]

I dont think the rate compounded, because Blizzard says total mana. Not current mana.

approximately 52 secs for original fountain (1%) to regenerate full mana.
approximately 27 secs for edited fountain (2%) to regenerate full mana.

The fountain regenerates about 50% faster for no reason.

Interesting, that means all abilities using that mana regeneration aura will do the same, does anyone know if this is the case with unholy aura?

That's right, it's about twice as fast, due to unknown reasons.

Mana regeneration neutral 0,5 equals 1 mana per second when percentage flag is off as well.

Well my Guess for that doubled regeneration is a tactical balacing reason from Blizzard and no bug.
It benefits staying inside the Fountain without making it useless for running in and out.

Gamesituation observation:

1. The Regeneration grows over 1 or 2 seconds to the doubled amount of the value insert into Object Editor. Even if you just look at the MP Number you can see a acceleration in this first 2 seconds.
   
2. If moved out of the Fortain the Regeneration keeps for ca 2 seconds with the Value insert in Object Editor.
3. Or it keeps for 3 or 4 seconds but the unit loses after 2 or 1 seonds half the regeneration gained by the fountain.
   
4. The Doubling apperead in fix and % regeneration.
5. On some situations a trippled regeneration was observed but that might be a result of only testing with a frequenz of 2.

Conclusion: Each fountain grants 2 stacks of Regeneration with ca 2 second grow/duration time. If moved in and out the benefit is lower from the fountain but there is still is one. in the other hand staying inside gives you both regeneration stacks -> more Regeneration.

Edit: Don't forget for what purpose Blizzard created the default skills. Fountain's are in melee games powerful locations which you can't stay long cause everyone is visiting them.

I just tested Briliance (Archmage-Aura) and Unholy-Aura (Death knight) they work fine (except on Skilling if the Fix /( % of max) mod is switched than the regeneration becomes quite troublesome From % -> fix instant heal; fix -> % no change in my test until unit regained the buff).
After all They have to according to my Theory that for fountain this double Regeneration is all part of Blizzards wanted features.

I assume you used game time to measure the regen time instead of real time? WC3 is mostly played at a faster than real time speed so more than 1 in game second occurs per real second.
