Kicks and Speeds: Recoil In-Depth

[probaddie]

Another discrepancy, and it's a huge one: GunKickReducedKick affects Viewkick, too! It's almost certain that this is what was giving the G36C and SCAR-L their incredible two-round burst accuracy all along. I'll update with revisions and diagrams tomorrow.

Why hasn't this gotten government funding yet?

What makes you think it isn't?

Sorry, what's that? "Common sense," you say? Pfft, well, but... yeah.

You don't know the cod community as well as you should.

You're not gonna derail this one, Mouse. Shoo!

:c okay

recoil is fun!

You're damn right it is.



This gun needs a higher adsGunKickSpeedDecay value.

That guy is so fortunate.

The part about random number generators is just silly. There isn't a different random number generator for every possible single range of numbers. They generate a specific range(typically a long integer or a real between 0 and 1) that is then adjusted to match what you need(the random function typically has that, but it's very simple to code it yourself). You can just use the appropriate % of the range for each side and it would be a very simple solution that requires very little code.

To give a very simplified example - you roll a 6 sided dice to determine gun kick and the gun kicks from -6 to -4 or from 4 to 6, If the dice rolls a 1 the gun kick would be -6, 2 -> -5, 3 -> -4, 4-> 4, 5-> 5, 6-> 6. I.e. the first half of the range is decreased by 7, while the second half is used directly and there you have it - one random number easily used for 2 ranges.

Before I respond I'll preface what I'm going to say with the following from the end of that section:

This is only one possible way in which Black Ops II may implement a minimum kick mechanic. It must be stressed that this is all speculation and cannot be verified without being able to read the weapon files or the game's source code.

Of course you're not wrong with anything you said. I'm well aware that the RNG chooses a number in the range [0,1] and scales appropriately. I just didn't think that detail was relevant as long as it was understood by the reader that, when all is said and done, the velocity is chosen from a uniform distribution with the given range. Why introduce more complications into an already technical subject?

And yes, it's not impossible to use that fact to create a generator that can choose a number uniformly within the two ranges determined by the minimum, maximum and minimum magnitude numbers, rather than choose the number uniformly between the minimum and maximum and then "bump" that number up or down accordingly using a conditional statement. I was only arguing that the latter was simpler to code, and thus less prone to error. (How do you handle exceptional cases, e.g. when either the minimum or maximum is less than or greater than the minimum magnitude?)

You are certainly right about your first point, and possibly correct about your second. But the second only challenges a theory I presented as speculation in the first place -- you may take that as you will.

In Advanced Warfare we are given two new variables:

adsViewKickMag
hipViewKickMag

Any idea what these do? The word "mag" seems to imply magnitude or something. Things with typically "low" recoil (i.e. ARs and the EM1) have "0" for this value, SMGs have "15", and LMGs have "30".

Well shit, that's what I miss out on by skipping Ghosts.

About the Lynx. In most recent patch they have removed min/max view yaw kick completely and decreased min/max pitch kick to 0/5 yet adsViewKickMagMin still remains the same - 100 degrees/sec so pitch kick values has no effect on recoil, it will always kick up at same speed, isn't?

Yes, that's what is expected - I assumed as much in the latest update to my recoil plots. Unfortunately, I don't own a copy of the game and could not verify that theory myself.

I fucking hate you guys sometimes.


Full disclosure: at the time Advanced Warfare was released, I was in the middle of a school term, with six computer science courses on my plate. That, more than anything, dictated my decision not to purchase the game.
