So I asked this question in my own mod thread, but I thought it might be good for more general discussion here. Basically, the question is which might actually be better for players in general: recoil that kicks your aim angle up, or recoil that just makes your gun spray more wildly without actually changing your aim. I listed some pros and cons. -"Realistic" Recoil that throws your aim off- Pros: Well obviously its more realistic and physics-y. Cons: It requires more direct control from you, since you have to actually counteract the movement manually with either the aim up/down keys or the mouse. So, it'd be harder to actually deal with. -Recoil that just makes your gun spray more wildly, without moving your actual aim angle.- Pros: You don't have to actually control your aim. Instead, you simply aim and then fire controlled bursts or single shots. Cons: Less realistic, and maybe even kinda funny-looking. So, what do you guys think? I could see people actually arguing that the increased-spray method might be better since it requires less twitch-adjustment from the player. I can see how direct aim-affecting recoil might be annoying for those who aren't crazy action/fps type gamers.

Realistic recoil all day erry day.

If you've ever played Day of Defeat, I LOVE that game's recoil. It makes full-auto fire take a lot of skill, but have a huge tradeoff.

Hrm. Welp, the only problem is somebody needs to figure out how to get realistic recoil to work even when mouse aiming. It ain't being an easy thing. I've already got a thread about it going on the lua board.

That's assuming that gif is an example of mouse aiming. If it's non-mouse aiming, its no help at all. I already PM'd him.

Yes it is mouse aiming. Code: function Create(self) self.recoil = 0; self.ff = false; self.f0 = ToMagazine(self.Magazine).RoundCount; self.f1 = ToMagazine(self.Magazine).RoundCount; end function Update(self) if self.Magazine ~= nil then if self.ff then self.f0 = ToMagazine(self.Magazine).RoundCount; self.ff = false; else self.f1 = ToMagazine(self.Magazine).RoundCount; self.ff = true; end if self:IsActivated() and self.f1 ~= self.f0 then self.recoil = self.recoil+0.2; end end if self.HFlipped then self.RotAngle = self.RotAngle-self.recoil; else self.RotAngle = self.RotAngle+self.recoil; end if self.recoil > 0 then self.recoil = self.recoil - 0.025; end end attached to a gun =

I definitely would say muzzle rise is more important, but for some weapons, also adding spray (or variance to the magnitude of muzzle rise) can also be suitable, to make a weapon seem less in control without being a complete skyshooter. But even just spray recoil is a massive improvement over "this is spread of your weapon, regardless of how fast you fire" for automatic weapons, in my opinion.

Well done, Mehman. Looks pretty sharp

So then the ini code would have the gun firing dead straight if you disabled the lua simulated recoil, which would pretty much render the code useless?

If you wanted complete control to yourself in Lua, yes, you would want to set all .ini accuracy and spread values to 0. If you wanted to just have some general inaccuracy along with recoil, or a fixed amount of inaccuracy for unsupported fire, you could do that just as easily with the .ini values, though. Here's what I came up with, a combination of spread and muzzle rise. It's probably technically inferior and less efficient compared to mehman's, but it demonstrates the idea well enough. Code: function Create(self) self.recoilfactor = 0.06 --radians self.recoilrecovery = 0.01 --radians per lua update self.recoil = 0 self.recoilspreadfactor = 20 self.recoilspreadrecovery = 3 self.recoilspread = 0 end function Update(self) --determine the root object. self.y = MovableMan:GetMOFromID(self.RootID) if self.y:IsActor() then self.z = ToActor(MovableMan:GetMOFromID(self.RootID)) else self.z = self end --held? if self.z:IsActor() == true then --if held --just fired? if self:IsReloading() then self.justfired = 0 else if self.magcount ~= self.Magazine.RoundCount and self.Magazine.IsFull == false then self.justfired = 1 self.Sharpness = self.Sharpness - 1 else self.justfired = 0 end self.magcount = self.Magazine.RoundCount end --recoil --add recoils if self.justfired == 1 then self.recoil = self.recoil + self.recoilfactor self.recoilspread = self.recoilspread + self.recoilspreadfactor end --recover from recoils if self.recoil > self.recoilrecovery then --if recoil's above 0, there's still recoil to recover from self.recoil = self.recoil - self.recoilrecovery elseif self.recoil < 0 then self.recoil = self.recoil + self.recoilrecovery end if self.recoilspread > self.recoilspreadrecovery then --if recoil's above 0, there's still recoil to recover from self.recoilspread = self.recoilspread - self.recoilspreadrecovery elseif self.recoilspread < 0 then self.recoilspread = self.recoilspread + self.recoilspreadrecovery end --actually recoil if self.z.HFlipped == true then -- Left self.RotAngle = self.RotAngle + (math.random( -self.recoilspread, self.recoilspread) / 1000) - self.recoil else -- Right self.RotAngle = self.RotAngle + (math.random( -self.recoilspread, self.recoilspread) / 1000) + self.recoil end end end I did glance at mehman's code, there, but the only thing from it that I remembered and applied was the usage of RotAngle, which works out very well.
