A DPS Simulator 2 - SimFF

[pandabearcat]

Hello all, I'm wondering if anyone's tried the simulator and varied up the sample rotation I put? I'd like people to test to see if the script needs additional features in order for you to write your rotations. Also if there are any bugs or inconsistencies in the way it handles more complex priority lists.

Furthermore, here is the source code for the "UI". As you can see it is extremely simple. Should people want to create their own graphical UI I welcome you to do so - all you need are hooks to the engine and parser's events and you're good to go. It simply isn't a big focus for me because the goal is to output the raw data people need to come to their own conclusions - if you want to use a graphic interface, if you want to export it to mathematica and do statistical analysis, go right ahead!

Simply reference the needed dll (SimFF.dll and SimFF.Script.dll) and you're golden.

EDIT: I will attempt to put in the new lvl 60 formulas at some point today, though I am working on other tweaks at the moment. I am also pretty caught up in fourth of july stuff with friends and family, so likely not much work will be done until next week. Have a safe holiday.

How do I compile this? I'm ultra scrub when it comes to computing languages/compiling/decompiling etc etc.

[pandabearcat]

You need visual studio 2010 (or higher). I think there is an "express" free version you can download. You need to create a new solution, add the UI source to the code, add the two necessary dll files as references (right click references, add, SimFF and SimFF.Script).

You can then compile/build the project.

There is a precompiled version on the first page downloads. I provided the code to this to let people see how to hook into the engine - if you want to make a GUI or something more advanced all the data and options you need are right there.

((CRT-354)*0.0002330) + 0.0495080

Critical Hit Rating Calculation. Everything got neutered, lmao.

And I thought that gear differentiation before was bad...

[Dervy]

Just go to the "How to Dragoon Per Second" thread, post 4 and check out the weightings. Just, lmao. Looks like a rat getting caught in a blender. It's nasty.

Also, does the 0.0002330 multiplier fit your Critical Damage scaling data points Viridiana? (or resemble it at least)

Fits pretty close to what I have so far, yeah. Got anything for the % damage, though?

[Dervy]

It's roughly the same. Could you try ((CRT-354)*0.0002717)+1.4370748 and for any Data Points that don't fit properly, give me the Critical Hit Rating, and the min/max damage values with no crit + crit?

EDIT: For Critical Hit Chance, use (((CRT-354)*0.0233018) + 4.9508) instead. Just makes it so it's a whole number %. Excel converts 10% to 0.1, for example, that's why the calculation was off (or you could multiply by 100)

Well, that fits pretty well (within rounding errors, basically). The only times I get things that don't match my observations is when there's an oddity in my observation (incomplete range or too much range).

[Dervy]

Yeah well, the Critical Hit Damage Formula is pretty much like my own Damage Models. Heavily reliant on the numbers and rounding range. It's annoying, but not much else we can do really.

Updated Crit Damage Formulae: ((CRT-354)*0.0002335)+1.448234

Turns out the Critical Hit Damage and Critical Hit chance scaler is very close.
