UAV attack drone camera shaking in multipalyer
Assigned, WishlistPublic

Description

This ticket remain open for several versions of a game, it is issue, not feature request.

  • Issue only appears in multiplayer
  • It is somehow tied with UAV AI and its behaviour on loiter (my guess it is correcting itself every second leading to the shaky camera)

Camera flickers up and down, left and right with very high frequency. Shake frequency increases with lower server and client fps

It is extremly hard to aim on high zoom levels. UAV operator has to spam "lock uav camera" button in order to aquire a lock on vehicle or desired target. Otherwise slightest movement of mouse sends aim way off the target.

However, similar visor was recently added to the game with 1.60 update. It is Wipeout targeting pod. Basicly serves same function, but works way way smoother. it is easy to aim and move around. (see updated video demonstration)

I personally prefer shaking, looks realistic

I am not saying it must be magneticly stable (Drone in midair after all) but how it is in current version just makes aiming and designating very painful for operator

It only difficult on high zoom, I presume? To me sounds like balance.

Camera is really lagging in MP games,it's unbeliveable frustrating to lock on targets.

Shaking is too big.

Modern stabilization systems are quite effective. Look at the targeting pod videos and AH-64D TADS videos. Future stabilization systems may be even better.

I just tried this issue in the dev branch (1.33.127690) and I am not able to reproduce it. Your video with F-18 is basically how it works for me even with Greyhawk. Are you able to reproduce this issue even in current version of the dev branch? Do you use any mods? Thanks

Ah my bad, I switched to dev branch (1.33.127690) and tested — issue appears only in multiplayer. So in order to reproduce it, you need:

  1. Go to editor
  2. Place UAV operator unit
  3. Place UAV (gayhawk) with elevation 500
  4. Save the mission for multiplayer use
  5. Go to multiplayer screen and hit "new"
  6. Start a server (lan or internet) with altis map and mission you just created.
  7. Open up UAV terminal
  8. Connect to Grayhawk
  9. Take turret controls
  10. Zoom at max level

I can confirm happens in MP only

Ok, I am able to reproduce it now. We will check this issue, thanks for feedback!

Also similar thing happens when gunner in auto-hovering attack helicopter. Do i need to make another ticket?

No need for another ticket at this moment. Fixing of this issue hopefully fixes the attack helicopter issue as well.

1.36 stable. Issue still present. Despite this line in changelog:
"Tweaked: Small change for speed usage in MP prediction (should lower camera zoom flicker)"
Here is the updated video of issue: http://youtu.be/_uezKtn-_eI

Turns out it is somehow affected by AI flying algorithms — when Greyhawk flying in a straight line — sight is perfectly stable, but when it flying in circular path, it jumps and shakes a lot. Same with the Kajman — when using auto-hover, zoomed up visor is shaking like crazy and without auto-hover it's almost perfectly stable. Hope this info helps

Also comment from YouTube video, representing exactly what i was experiencing when talking about issue №2:

The mouse is incredibly hard to control and is very sensitive to the point of were I can't put the cross hairs on a tank at 2000 meters up and 1200 meters loiter.... This is not a problem with my mouse as I do not experience the problem when in a ground role, I'm can let go of the mouse and the camera will stay still but if I move it a fraction in any direction, the camera moves wildly away from were it was aimed at. I can find is that whenever I play, I'll move the camera but it's as though the camera is affected by the uav movement and not on a gimbal and smooth" (like on F18 mod part of the video: http://youtu.be/_uezKtn-_eI )

Currently why camera shaking happens is because of the camera shake difficulty option 22394

St. Jimmy, sadly it is not. Both CameraShake=0; in *.Arma3Profile and enableCamShake False; in init.sqf has no effect on issue

Problem is still present, and it's impossible to aim with the UAV camera with precision.
At 500m above ground the camera shakes so much it has a dispersion of around 5-10m.
Taking accurate aim is impossible because everytime you make small corrections the camera goes off target by far.
This happens on dedicated server only, in editor and locally hosted games it works just fine.

I'm not trying to make publicity or anything but take a look at this video i made sunday and you'll notice how painful that is to make any use of the UAV camera:

Camera movement got much more better now (v1.42), but twitching on high camera zoom is still present

Updated ticket. With the 1.60 camera got worse again. But we have hope with newly introduced Wipeout targeting pod!

Is this likely to be a locality issue? Vehicles in multiplayer are local to the driver, in this case would that mean that if the virtual AI in the driver slot were local to the server this would make the UAV local to the server even when the player is in the turret position?

Has there been any work to fix this issue? The camera still shakes extremely bad when loitering.
I also wish their was a 1,500m ALT setting. 2,000m ALT causes the ground to be cloudy and sometimes unseeable on certain servers.

I think it was acknowledged but considered low priority. You can set desired altitude by taking pilot controls of the UAV and lowering altitude of the Greyhawk manualy. It will keep altitude when you release controls

Issue seems to be resolved with 1.68

(All UAV's now has lowered maximum loiter radius — 1500, but i think this is a good compromise)

Needs more testing with lower server and client fps.
