Summary
positional.GetTransform is unstable and reports unexpected translation values. This issue is more apparent when calculating the velocity between two translation vectors and moving the character or vehicle at a relatively constant top speed in a single direction. Additionally some dirty values repeat in a certain pattern (see rocket racing car when standing still). While dirty transform values that appear when standing still could be filtered out, smoothing dirty transform values while moving is a non-trivial task for the end developer.

Verse
What Type of Bug are you experiencing?
Stability
Steps to Reproduce
- Create a verse device or SG component
- Let the device observe either
fort_characterorfort_vehicleon each tick - Get DeltaTime either via simulation elapsed time or via tick events
- Compute velocity between two transforms (for example in KPH)
- Start moving the character or vehicle into a single direction (via the forward key on a keyboard for example) and wait until the max speed is reached
- Observe velocity below and above max speed at each tick using
Sleep(0.0)or tick events in case of scene graph, over time there will be unexpected velocity bumps and drops - Visualize the transform values using debug draw. After reaching the top speed, any too low velocity should mark the transform as yellow, any too high velocity should mark it as red, while normal values remain green.

}
The issue was reproduces in the following configurations:
- Device with
Sleep(0.0) - Scene Graph with
Sleep(0.0) - Scene Graph with
TickEvents.PostPhysics.Await() - Scene Graph with
TickEvents.PrePhysics.Await()
This issue has been tested with (KPH values)

For some reason there’s a pattern in that periodically repeats over and over again! Re-running the test, yields the same pattern again.

For some reason the biplane reports values as if it’s constantly moving, even though it’s not. Additionally it has the same issue of periodically dirty transform values.

The above represents a plot of two recording sessions where a rocket racing car would normally accelerate forward using a keyboard key. Each spike represents where the velocity value between two vectors spiked or dropped due to unstable transform values returned by the server. The above graph represents values record every single tick during 120 seconds.
Expected Result
Stable transform values. The calculated velocity from transform values should not periodically fluctuate.
Observed Result
Unreliable transform values with a lot of periodically dirty data.
Platform(s)
PC
Additional Notes
From the perspective of my client, there’s 0% packet loss detected!
This bug is POTENTIALLY related to the following issue: [CRITICAL] [BUG] `fort_character` and `fort_vehicle` periodically report dirty transform values while standing still
