I know that Ana's scoped shots with her Biotic Rifle are hitscan, but what is the projectile speed of her unscoped shot? And the speed of her Sleep Dart?
According to this wiki, the projectile speed of her Biotic Rifle is 85.5 m/s. I don't know why I didn't think to check the Overwatch Wikia until after I posted this question.
I still don't know about the speed of her Sleep Dart though.
Edit: I did some non-scientific testing of her sleep dart. I went to the practice range and fired three times at a test bot at a range of 40 meters. The video I recorded can be found here, and the screenshots of the start and end times are below. I've chosen the start timestamp when I see the flash of light from the gun and the end timestamp when I see the hit mark on the crosshair. In the screenshots, the timestamp is in the bottom left hand corner.
- 23.784s to 24.550s (delta = 0.766s)
- 37.800s to 38.567s (delta = 0.767s)
- 51.634s to 52.400s (delta = 0.766s)
So if we do math:
- 40m / 0.766s = 52.22 m/s
- 40m / 0.767s = 52.15 m/s
So Ana's sleep dart projectile speed is around 52.2 m/s. Totally not a rigorous scientific test, but it's something.
I did some test too, comparing Sleep Dart and Biotic Rifle Shot. Here is the video:
I believe it could be more illustrative, since I've used moving target you can see that you must fire sleep dart much more far away from the target if you want to hit it.
I used practice range, being at second floor and firing at the most far away moving bot.
46 frames from the moment of animation start (yellow ability icon) to hit (red half circle at the bot) 28 frames from the moment of firing (bullet out of the gun) to hit
14 frames from the moment of animation start = firing to hit
If shot speed is 85.5 m/s
Then sleep dart speed ≈ 85.5*14/28 = 42.8 m/s ± 9 m/s (taking into account 1-2 frame error)
If we taking into account sleep shot animation (46-28=18 frames) and human reaction time (0.25s =15 frames), then we need to react ≈1.5 times earlier with sleep dart than with rifle shot (at the given distance used for testing).
