I have a family of sprites walking across the screen at different individual rates ("Move forward [#] pixels"). The same family is mirrored to walk the other direction as well (it's a city sidewalk). However, the mirroring makes the slower people fast and the faster people slow. Is there an expression to retain the mirrored sprites' forward movement at the same respective rates relative to zero, at the family grouping level?
