• data get storage lib: Pos[*] 10 reduces the direction vector resolution to 0.1-block increments (since Pos components are in [-1,1]), which can noticeably quantize motion direction at many angles. If this was changed to compensate for $VectorMagnitude now being scaled by 10000, consider keeping higher precision (e.g., use a larger scale like 1000 and adjust the later execute store result ... double scale accordingly) so non-player launches remain smooth and accurate.
