Black Ops II Recoil Plots

[probaddie]

Notes:

• All of these plots are at the same scale. You can directly compare them.
  
• Each plot represents 1000 simulations of the weapon being fired in a 15-round burst (or lower if the gun has a lower capacity). Shots 1 - 3 are in blue, 4 - 6 are in green, 7 - 9 are in yellow, 10 - 12 are in orange and shots 13 - 15 are in red. Grid lines are spaced one degree apart.
  
• These plots account for ViewKick, idle and spread only; the effects of GunKick are excluded. (They are practically negligible in BOII regardless.)
  
• The ten-degree boundary is accounted for, as well as the fact that your view cannot drop below your original point of aim -- though spread and idle may still cause shots to fall below the horizontal (yaw) axis.
  
• For every semi-automatic weapon, the firerate is assumed to be either the firecap itself or 625 RPM, whichever is lower.
  
• For the burst-fire weapons, the actual delay between the last shot of the last burst and the next shot is assumed to be the greater of the following:
  • 0.096 seconds, less the time since the last trigger pull (assumes the player cannot consistently pull the trigger faster than 625 RPM, the same assumption made for semi-automatic weapons)
  • The actual burst delay of the weapon plus the fireTime

Frequently (?) Asked Questions

Q: The HAMR uses a new recoil mechanic introduced in Black Ops II. How is this implemented in the plots of the HAMR?

A: There are three new recoil variables in Black Ops II: adsRecoilReductionRate, adsRecoilReductionLimit, and adsRecoilReturnRate. For every weapon except the HAMR, these variables are set to 0 ,0, and 1, respectively. However, for the HAMR these variables are set to 0.03, 0.15 and 1.00, respectively. The assumed theory is this: for each fireTime elapsed, the kick values are reduced by 3% (adsRecoilReductionRate), up to a maximum of 15% (adsRecoilReductionLimit). If the trigger is released, the reduction "returns" to the original value at a rate of 100% per fireTime (or 100% / 0.064 s = 1562.5% / s). So the HAMR will, if the trigger is released for more than 0.0096s -- practically speaking, if the trigger is released at all -- be using the full kick values again.

Q: The guns that always recover their recoil before the next shot (e.g. Ballista, DSR-50, etc.) have a blue square in the center of the plot. What gives?

A: The plots now incorporate idle into the simulations. Without going into great detail about idle itself, it suffices to say that idle operates on the yaw and pitch (read: horizontal and vertical dimensions) independently. Hence, the squarish plot. (If the idle was large enough in any plot, you could see the wavy pattern that idle actually makes. As it is, no weapon produces idle large enough to show this on plots at the given resolution. See this Wikipedia article for more on these wavy patterns if you are interested in the technical details. I do eventually plan on doing a full post on how idle works and what adsIdleAmount and adsIdleSpeed do precisely.)

Q: Can I use your plots in my video/forum post/whatever?

A: Yes, so long as you do not try to take credit for them. (Mentioning that they're mine would be nice, too.)

These seem pretty damn accurate from my experience. Granted, you'll rarely actually go to the yellow/red parts of the recoil due to aim assist (on consoles), manual (usually downward) correction, and the fact that it doesn't take long sprays to kill an opponent - but it does show some good info.

I KNEW the Peacekeeper had a recoil set closer to the TAR than the M27. What a shitty gun.

[Amirror]

Nice. This will certainly help.

Executioner...

Is this for the automatic or burst SWAT and M8A1?

Burst fire. We don't currently know how Select Fire affects CenterSpeed or ViewKick parameters.

[wg4f]

Okay. Thanks for making the thread btw. I was definitely curious about a few of the weapons

[banana]

Are you going to update your formula for recoil thread?

Yeah, eventually. But there are changes I need to make to account for the weapons that have variable firerates, so I don't know how soon I can get that done.

[d1ce]

Awesome dude! I feel like these plots are the most accurate representation of the gun's accuracy. Look forward to seeing them with different attachments and whatnot.

MMS reduces recoil on the M8 (slightly) and Peacekeeper (drastically, although it seems to have very fucked up hit detection). Possibly other guns as well.

There's no data to support that sentiment. I sincerely doubt the MMS reduces recoil.

[imrlybord7]

I could believe that the M8 only seems to have it reduced because of the reduced zoom, but the Peacekeeper is a completely different gun with MMS.

All guns get the reduced zoom. It's in your head.

[mmacola]

MMS possibly shows a different fire animation, which has more visual recoil to it. It can be pretty distracting with low fire rate guns (since the fire animation is more present instead of it being very quickly reset to its beginning again)

[KingVaroon]

Shouldn't the FAL OSW be a laser?

[mmacola]

Well if you manage to fire it at 625 rpm you would experience some recoil

[KingVaroon]

If I were to tell you that I was in fact firing it at 625 rpm (I may or may not be using a modded controller) and not experiencing anything close to the plots and that the FAL was still a laser, would you believe me?

No. I've fired it at the cap before and have experienced small amounts of recoil; hardly enough to make a difference unless the target is >50m away

[jaedrik]

Probaddie, do you know how much I love you?

[deston]

Nice work.

If you're using a controller, you're probably playing on console. If you're playing on console, you're probably not getting 625 RPM. Your framerate adjusted practical max RPM is probably going to be lower. Also, depending on the nature of your macro/controller it's probably inputting at a consistent interval, while your framerate (and by extension your RoF cap) is variable. If the cap drops below your macro speed you'll start dropping inputs, resulting in a lower-than-theoretically-possible RoF (giving the gun more time to recenter).

Thanks, aids. Couldn't have put it better myself.

blue: Tac45, 625 rpm.
red: Five-Seven, 750 rpm.

bolded ROF: both guns have the same ROF.

Sorry, wwa, but I almost never take frame coupling into account with my work; it varies too much from system to system (in the case of PC) and map to map to do that effectively.

[wwaa]

I added Tac45 chart to the above discussion abt 625rpm only and for comparison: 5-7.

the Question is:

how framerate impacts centerspeed?

I suppose centerspeed is "defined in frames", it is not absolute value in "recoil per sec", so at very low framerates centerspeed is low,
so you cannot say that low framerate reduces recoil, so the quote below is wrong (?)

Sorry, I misunderstood what you were saying. Carry on.

No, haven't even started. I'm working on getting the plots for crouching/prone LMGs/SRs working and implementing idle into the plotter. (I'm also trying to figure out how to upload it all without flooding Hey, Den with plot threads.)
