Is there an accuracy penalty for prolonged auto-fire?

[Honeycone]

Hi!

 

In some FPS games, the gun magically becomes less accurate during prolonged automatic fire (like, firing the entire magazine). To clarify, I mean when aiming, not when hip-firing. What this does, is essentially prevent the use of mag-dumping unless the target is very close to you (again, when aiming, not hip-firing). I could have sworn I experienced this during some combat but I can't recreate it outside of combat.

 

Has anybody else experienced what I'm describing, or am I just a bad shot during combat?

Yes, sustained full-auto or even rapid semi-auto fire will see your shots start to go wild. If you don't want to waste ammo, keep your bursts short, three or four rounds at a time, and don't fire again until you've fully recovered/pulled your sights back on-target.

 

And before you ask, no this is not a bug, it's an intended feature - and a fairly realistic one at that. There's a damn good reason most modern infantry rifles are only capable of burst fire rather than full-auto - f/a just wastes ammo unless you know what you're doing and can control the weapon during that 30 round mag dump.

 

If you want to tweak it, there are four values you want to look for - AimModelRecoilMinDegPerShot/AimModelRecoilMaxDegperShot both control how much physical or "felt" recoil a weapon has. AimModelMinConeDegrees and AimModelMaxConeDegrees both control the size of a weapon's maximum and minimum "spread"/cone of fire. Across all of a weapon's modifications that have any of those values, a total of -1 will give you a weapon with no recoil/muzzle climb and pinpoint accuracy even during mag dumps. Anything less than or over -1 e.g a total value of -1.1 or -0.9 will give you some recoil - in fact if you go "over" -1 for AimModelRecoil, the weapon will actually kick down and left instead of up and right.

Thanks for the info! Will changing the "cone" values change the base accuracy of the weapon, or only the accuracy decrease as you're magdumping?

I -think- it changes both, but I'm not sure.

The penalty is loosely called cumulative climb. The recoil of a shot displaces the barrel. The next shot displaces it a little more. The cumulative effect is that by the fourth of fifth shot, you are shooting clouds.

 

The recoil and aiming cones are set in the AimMode form (CK).

 

A aiming cone value of 1 means there is no cone. Point of aim is point of impact.

 

I forget the values for the recoil cone, but @WiskeyRiver2 seems to know his stuff and it matches my faulty memory for the most part. I believe him.

 

Now, the values in the AimMode Form are the default for the weapon. The values can be changed by mods which modify the values up or down by setting fAimModeBaseStability, fAimModeRecoilMaxDegPerShot, fAimModeRecoilMinDegPerShot, or fAimModeConeIronSightMultiplier.

 

Hope that helps. Here is a link to a picture of the Object Mod form for the Hunting Rifles Long Ported Rifle Barrel. Note the changes in the Properties Modifiers box.
