Re: No Recoil For Steam

"The gun you are holding is rendered at a fixed 50 FOV ('Field of View'), but the world is rendered at 60 FOV for consoles and anywhere from 60-90 FOV on PC," Ubi explained in the post. "Because of this, any amount of movement we do with the First Person visuals off the center of the camera will immediately cause alignment issues with the weapon."
That turned out to be a bigger problem than you might think. Removing the offset eliminated a lot of the recoil effect and made weapons too easy to control, which led to the need to tweak the recoil of all weapons. But that led to another problem because the existing recoil system only enabled one pattern definition, which "left us with a system that is still very random number generator (RNG) dependent that pulled hard on the camera and made the weapons feel erratic or unpredictable."
To get around that, Ubi implemented "multi-stage recoil" that lets it define unlimited recoil data sets at any point during full-auto firing. "We can say to the engine 'For the second bullet use this recoil data set and for the third bullet, use this other data set' etc." it explained. "That way, we can say where every bullet goes in relation to the previous one."
Conversations about the new system are taking place on the TTS subreddit, and the response so far isn't what you'd call universally positive. There aren't a lot of people talking about it yet, but those that are generally sound as though they'd prefer to stick with the old system. One of the more thoughtful posts, from a redditor named Icemasta, states that while the original randomized recoil "might give some 'bullshit' moments, fixed recoil patterns are even more bullshit."
"When you once had to tap/burst fire at long range, with fixed recoil, you can now spray. This is actually a big issue in CS:GO, even at long range people will spray down because the recoil patterns are known and easy to use," they explained. "Hell, some of the recoil patterns currently on TTS are very reminiscent of CS1.5 AK pattern, which was a near straight up line. This can easily be 'abused' to simply aim at the chest and after 1-2 bullets you'd land a headshot, making it easier to land a headshot and lowering the risks. While one-tapping a head is still far better, it actually severely reduces the skill level."

1. Reissued letters patent No. 3727, granted by the UnitedStates, Nov. 9, 1869, to Edward H. Ashcroft, assignee of WilliamNaylor, for an improvement in steam safety valves, being a reissueof original letters No. 58,962, granted to Naylor Oct. 16, 1866,cannot, in view of the disclaimer of said Naylor in hisspecification, upon which English letters patent No. 1830 weresealed to him Jan. 19, 1864, and of the prior state of the art, beconstrued to embrace a combination, in every form of spring safetyvalve, of a projecting, overhanging, downward curved lip orperiphery, with an annular recess or chamber surrounding the valveseat, into which a portion of the steam is deflected as it issuesbetween the valve and its seat, but must be limited to acombination of the other elements of his device, with such anannular recess of the precise form, and operating in the mannerdescribed, so far as such recess, separately or in combination,differs in construction or mode of operation from those whichpreceded it.
2. Said reissued letters, thus limited, are not infringed by theuse of a steam safety valve made in substantial compliance with thespecification of letters patent No. 58,294, granted Sept. 25, 1866,to George W. Richardson.
English letters patent No. 1830, dated July 21, 1863, and sealedJan. 19, 1864, were granted to William Naylor, of England, forimprovements in safety valves and in apparatus connected therewith.The specification describes his invention as consisting,
"when using a spring for resisting the valve from opening, inthe employment of a lever of the first order, one end resting by asuitable pin upon the safety valve, and the other end of the leverresting upon the spring, the end resting upon the spring being bentdownwards to an angle of about forty five degrees from the fulcrum,so that when the valve is raised by the steam the other end of thelever is depressed upon the spring downwards, and at the same timeis moved inwards towards the fulcrum, thus virtually shortening theend of the lever, and thereby counteracting the additional loadupon the valve as it is raised from its seat by the greater amountof compression put upon the spring."
He also describes a contrivance consisting of a lateral branchor escape passage for a portion of the steam after it has passedthe valve, the valve being made to project over the edges of theexit passage, the projecting edges of the valve being made tocurve
slightly downwards, so that the steam on issuing between thevalve and its seat will impinge against the curved projectingportion of the valve, and a portion of it be directed downwardsinto the annular chamber surrounding the central passage, whichchamber communicates at once with the branch exit pipe, whilst theother portion of the steam ascends past the edges of the valve. Hethen says,
"By this means I am enabled to avail myself of the recoil actionof the steam against the valve, for the purpose of facilitating thefurther lifting of such valve when once opened; but I wish it to beunderstood that I lay no claim to such recoil action, nor to theextension of the valve laterally beyond its seat."
"in forming a flange around the valve, commencing at the outeredge of the valve facing, which flange is under cut and concave inshape, and the concave side is towards the seating of the valve,which has also a flange upon it, commencing at the outer edge ofthe valve seating, but the upper surface of this flange is convex,and corresponds nearly to the concave surface of the flange uponthe valve. There is a slight space between the concave and convexsurfaces of the two flanges, which diminishes towards the outeredges of the flanges. When the steam begins to escape from betweenthe surfaces of the valve, it gets between the concave and convexsurfaces of the two flanges, and its force thus acts upon a largerarea, and reacts upon the concave surface of the valve, and causesit to open to a greater extent than the ordinary valve."
Letters patent of the United States No. 58,962 were issued, Oct.16, 1866, to said Naylor for an improvement in safety valves. Thedescription of his invention in the specification is substantiallythe same as in that of his English patent. Nothing is said,however, of availing himself of the "recoil action of the steamagainst the valve, for the purpose of facilitating the furtherlifting of such valve when once opened;" nor is there anydisclaimer, as in the English specification, of the recoil actionand the extension of the valve laterally beyond its seat. The claimof the specification was the arrangement
in safety valves "of bent levers of the first order, acting incombination with a spring or springs, the whole operating in themanner and for the purpose set forth." Sept. 8, 1869, Naylorassigned his letters patent to Edward H. Ashcroft, who thereuponsurrendered them for reissue. The specification of the reissuedletters to Ashcroft, as the assignee of Naylor, which are No.3,727, and bear date Nov. 9, 1869, declares that the main object tobe attained by the invention, viz., the counteracting theadditional load upon the valve as it is raised from its seatproduced by the increased resistance of the spring,
"is accomplished by using a lever of the first order, one endresting by a suitable pin upon the safety valve, constructed andarranged as hereinafter described, and the other end of the leverresting upon a spring; but, in lieu of having this lever straightor nearly so, I propose to bend downward that end which is actedupon by the spring to an angle of about forty five degrees, so thatwhen the valve is raised by the steam the other end of the lever isdepressed upon or against the spring downward, and at the same timeis moved inward toward the fulcrum, thus virtually shortening theend of the lever, and thereby counteracting the additional loadupon the valve as it is raised from its seat by the greater amountof compression or tension, as the case may be, which is put uponthe spring; and my invention also consists in the valve C,constructed with projecting downward curved lip or periphery, andin the annular chamber D, surrounding the valve seat, whereby, asthe spring is compressed by the lifting of the valve, theprojecting lip of the valve and the annular recess are available incausing an increased pressure on the valve, and thus overcome theincreased resistance of the spring, due to its compression, ashereinafter more fully set forth."
