A DPS Simulator 2 - SimFF

Yep.

So basically each crit rating gives between 0.0001977 and 0.0001749 crit (avg 0.0001863). This is pretty huge variance.

What you really want is to be able to discriminate between 657 rating and 658 rating.

To do that, you need a variance less than the avg rating diff, which 0.0001863. Which means you need something on the order of 10 million trials =DDDDDD

EDIT: oops I hit my post cap.

So here is the grammar right now. Its kinda really ugly? I'm going to have to see if it has any conflicts (probably)...maybe I can get an intern to do this for me.

Here is the FFscript grammar.

Its really bad right now. I need to resolve a lot of conflicts before it can be used, and I'm lazy.

Maybe I can get a college intern to do it for me.

             * setup  :== "[SETUP]" setupStatements
             * setupStatements :== setupStatement setupStatements | .
             * setupStatement  :== actorAdd | varAssign
             * actorAdd :== actorList "+=" string
             * actorList :== "players" | "targets"
             * varAssign :== var "=" val
             * var :== string varb
             * varb :== "." string varb | .
             * val :== number | string
             * precast :== "[PRECAST]" actionStatements

/hate

Well, I guess I can leave my comp on overnight. Bleh. Good news is that IR doesn't seem to affect the crit damage range, which is basically what we expected. Which is good because I somehow got it in my head that a buffed Sneak Attack would give really accurate numbers on how much it boosts crit damage. . .

Whee, the grammar works.

I opted for grammar simplicity and to do more of the semantic work in the backend, instead of trying to parse specific keywords.

As far as I can tell the grammar is correct. Next step is the semantic parsing and attaching actions to nonterminals.

Here is the full grammar:

actionb  (Nullable) 
   actionb -> , string actionb 
   actionb -> 
actions  (Nullable) 
   actions -> string actionb 
   actions -> 
actionStatement
   actionStatement -> ( conditionals ) { actions } 
   actionStatement -> comment 
actionStatement+
   actionStatement+ -> actionStatement+ actionStatement 
   actionStatement+ -> actionStatement 
actionStatements  (Nullable) 
   actionStatements -> 
   actionStatements -> actionStatement+ 
actorAdd
   actorAdd -> actorList += string 
actorList
   actorList -> *players 
   actorList -> *targets 
boolVar
   boolVar -> string boolVarb 
boolVarb  (Nullable) 
   boolVarb -> . string boolVarb 
   boolVarb -> 
conditional
   conditional -> boolVar test number 
   conditional -> ! boolVar 
   conditional -> boolVar 
conditionalb  (Nullable) 
   conditionalb -> & conditional conditionalb

   setupStatements -> setupStatement+

Here is a sample DRG rotation, not optimal, but it works.

# setup diagnostic or no - diagnostic runs 1 run with log output, for testing your rotation
sim.diagnostic=true

# otherwise setup sim trials
sim.trials=10000

# i/o
sim.output="./output.txt"

[PRECAST]
# place a sequential list of ogcd/gcd actions here
# any action that is offensive will begin the sim timer
# however, you may place as many actions as you like
# if you have a set opener rotation you wish to follow, enter it here
# and the [GCD] actionlists will follow once the action queue is complete
(){x_potion,blood_for_blood,heavy_thrust}

[GCD]
# remaining is set to 0 if an aura does not exist
# you do not need to test for both exists and remaining
# if an action is in the queue, no further actions will be run
# if a condition is satisfied, the sim will attempt to cast the action

(){true_thrust,vorpal_thrust,full_thrust}

[OGCD]
# you'll need this unless you want to constantly clip GCDs
# actionlist execution stops as soon as a successful action is entered
# blank actions are automatically successful
# be very careful queueing oGCDs. They will automatically be run in sequence, without regard for clipping into a gcd

Updated the grammar today. I realized I was trying to be too "generic" and ended up writing a kind of lazy grammar that is technically very extensible, but put too much work into the backend semantic parsing.

I rewrote the grammar to be much longer and restrictive, which allows me to also write the backend quicker (once I figure out how...).

The new grammar also supports multiple actors, which hilariously the sim only half-supports (it doesn't support multiple stacks of the same aura, nor does it support cross class buffs). Oh well. At least the future looks bright.

Irony's documentation sucks. I need to figure out how to overwrite the AST actions.

New grammar:

I posted this in the DRG thread, but it would serve better here:

Also for any of you wondering how SS scales with GCD, it's now 0.00037735 per point of SS. So you can do 2.5-((SS-354)*0.00037735)) to calculate your GCD. Alternatively, you can use this formula 2.5-(0.01*(SS-354)/26.5)) which should do the exact same thing, just a lot more accurately.

[Junified]

Hah, what a great language.

Thank you for the research. I'll work on it more today and see if it won't be too hard to get at least a parser going.

Junified, the most useful stuff I need is animation delays. Without that data pretty much every oGCD class is going to have a flawed sim. It isn't too necessary to be exactly precise, but we need to be precise enough that if someone is trying to stuff 2 oGCDs into a GCD that it will delay their next attack some.

So basically I need the animations delays of every ability, GCD and oGCD.

At some point we also need updated damage formulas but that is really grindy afk work so maybe talk to Dervy or Viridiana.

Ok I'll have to get on that I have a working parser atm and would you want video for reference for the animation timing?

Dervy you're a wonderful person. <3

[pandabearcat]

HOLY BUTTS finally found documentation (rather, examples) of how the AST node setup works.

Now need to go through the grindy process of creating a node for each nonterminal.

My god we might actually be able to release on friday. If I do, I expect someone to come help get my char to 60, cause I haven't had any time to play >.<

EDIT: work has begun. I'd forgotten how much more work semantic is than syntax parsing. Hwarrgagahblargh.

[Viridiana]

So, just as a partial update. . .

Still collecting swings at 657 crit, because seriously screw margins of error, but I have a fun data piece on how much that boosts crit damage by. Non-critical damage of 500 potency SA with 689 AP, 260 Det, and 59 WD with Venom, B4B, and Dancing Edge up is 1793-1982. I don't have the full critical spread yet, but I do have a 3012 data point, which means at least a 1.5196~ multiplier for ~12% crit rate. And mind you, 3012 might be a few points shy of max, too. . .

[Dervy]

Just to make sure I'm not being dumb (the heat makes me rather dumb and incapable of comprehension), 12% Chance with 1.5196% multiplier at base 354 Critical Hit Rating, right?
