Are bullets spawned at an angle from the centre of the barrel or parallel to the barrel within a circle surrounding the barrel?

This has to do with spread. I'm wonder is the bullet spawned from the barrel and angle away according to spread (So the bullet fires at an angled trajectory from the barrel) Or are they spawned parallel to the barrel within a circle governed by the spread value.
If it's the former, spread get significantly worse at range as your bullet will continue to travel away from your target. If it's the latter, it won't be as much of an issue as it'll fly straight and true.

The values for spread are in degrees.

Degrees implies an angle.

I should note the values are a radius, not a diameter.

Next, wanna try adding a guy that you KNOW is bad, and just testing to see that? Example: PP-2000 (god I so wanna love this gun, and yet...)

Example: PP-2000 (god I so wanna love this gun, and yet...)

PP-2000 added. Y'know, it's not that bad....

Yes, it comes in last so far, but that is mostly because I'm making it shoot at 100m ADS - Not Moving as one of the criteria. Even then, between 50-100m Not Moving, when you include Useability, it is only 1.37% worse than the MTAR-21. Within 50m then it even beats the A-91.

Have a look, vs. the A-91 Carbine:




Using it with Muzzle Brake and Compensator is a wash in terms of overall performance. Comp is SLIGHTLY more accurate, while MB is SLIGHTLY more easy to use. Their overall scores are basically tied, with MB just ahead. I guess either can be recommended.

But... You can't be counting for the fact that it takes 9 bullets to kill at "long" range... Don't you dare tell me my A-91 is worse than a 9 BTK 650 RPM mediocre PDW.

Also. Just go heavy barrel. The recoil is low enough.

Well, technically...

Comparing a PP2K with HB and an A-91 with comp and stubby (as you suggested in an earlier post), at 50m not moving, the A-91 is only better by 4 damage per hitrate. While at 75m and 100m, surprisingly the PP2K does better than the A-91 (I'm pretty damn surprised as well).

And 10m and 50m moving the PP2K also does more damage per hitrate than the A-91. At 25m the A-91 is only better by about half a bullet's damage as well.

In addition, the PP2K has a much larger mag size and substantially less recoil. And it looks hella awesome. So comparing the A-91 to a PDW is of some worth after all, as the PP2K is better (technically, not practically) than the A-91.

Mind blown.

I... I...

Zer0Cod3x explained it very well. If you look at the raw numbers right here on Symthic Comparison, you can see how that happened:

A-91 vs PP-2000 | BF4 Weapon Comparison | Symthic

A-91's "23%" RPM advantage only afforded it 1 extra round.

Reload times are wash.

Velocities are wash.

V-Recoil are wash (and this is HBar on PP2k vs. A-91 without).

Hipfire and ADS - Moving are better on the PP2k, but it's a PDW and not the surprising part.

The surprising part is that, as equipped (and we see above that PP2k HBar has almost same V-Recoil as A-91 without HBar so why not?), the PDW performs better at 50 - 100m than a bloody Carbine. Why?

H-Recoil Spread, 0.525 vs. 0.45, advantage PP2k.

SIPS, 42% better on the PP2k.

And here is the most important part. ADS - Not Moving Spread, 0.35 vs. 0.2, 43% improvement.

Without HBar then of course the PP2k loses, which is why when I add all the attachments together for an Overall Ranking, it would slot below the A-91. Run HBar on it, though, then... I'm sorry

It always spawns at the same spot, but the angle of its trajectory is randomised, yes.

So if a weapon had 0.2 spread, it could spawn from the barrel anywhere between 0 and 0.2 degrees from the barrel?
The bullets don't spawn from the barrel (on your 3P model). The bullets spawn from a position offset relative to your camera(/face). At launch bullets spawned from the exact center of the camera (between the eyes, near the top of the head), this was the reason to why headglitching was a thing. You only had to expose the top of your head in order to shoot over something.

With the "headglitch fix" the bullet spawn point was offset lower, the exact offset varies from gun to gun but on average they spawn pretty close to where you hold your gun in 3rd person.

The spread value of a weapon denotes the maximum deviation (in degrees) that the bullets can have from your point of aim (offset according to the headglitch fix).

So to answer the question in your first post: yes, the deviation becomes worse with range. That is a very deliberate thing and it's why spread is a core balancing factor in order to define effective ranges for different weapons: high spread -> high deviation at range -> lower damage output at range due to more misses.

And reading Youtube comments still gives me Turbo Cancer.

It really is quite frustrating when Helen Keller sets up her LMG in the only doorway in/out of an area.

What kind of question is that? Since when is cheese ever a bad idea?

Degrees (Although I wouldn't be surprised if there were some multiplications going the calculations).

Radians would mean that at 3.0 (3 radius = 180 degrees), your bullets would be going backwards.
At 7.0, the maximum hipfire spread, they would be doing a looping midair before hitting their target :|

All values on the site are in degrees but some of the data in memory are in radians, mainly because they are just so much more convinient for calculations.

@Sheepnub
To correct you a little: pi = 180 degrees, not just 3 ^^
Links to users' thread list who have made analytical/statistical/mathematical/cool posts on Symthic:
  • 3VerstsNorth - Analysis of game mechanics in BF4 (tickrates, effects of tickrate, etc)
  • leptis - Analysis of shotguns, recoil, recoil control and air drag.
  • Veritable - Scoring of BF4/BF1 firearms in terms of usability, firing and other mechanics.
  • Miffyli - Random statistical analysis of BF4 battlereports/players and kill-distances. (list is cluttered with other threads).
Sorry if your name wasn't on the list, I honestly can't recall all names : ( . Nudge me if you want to be included
