Prismatic ArticulationBody moves in opposite direction when using targetVelocity
Reproduction steps:
1. Open the attached “IN-110956.zip” project
2. Open the “SampleScene”
3. Enter Play mode
4. Observe the Cube on the right
Expected result: The Cube moves upwards towards the +1 limit
Actual result: The Cube moves downwards towards the -1 limit
Reproducible with: 2023.1.0b1, 6000.0.55f1, 6000.2.0f1, 6000.3.0a4
Reproducible on: Windows 10 (user reported), Windows 11
Not reproducible on: No other environment tested
Notes:
- Position-based control (using target + stiffness) works correctly in the expected direction
- Physics Debug window shows inverted velocity values (e.g., targetVelocity = +1 → actual velocity = -1).
- Issue persists regardless of Damping values (tested from 1 to 1e+25)
