What happens to the track if it turns right after a frame update?

• A. The track will jump
• B. The track will slow down
• C. The track will disappear
• D. The track will reverse direction

Answer: (A)

Frame-based motion updates compute position each frame. When a turn is applied right after a frame update, the velocity direction changes abruptly for the next frame. If the track is rendered on a discrete grid or uses integer pixel steps, that sudden change in direction translates into an immediate shift in where the track is drawn, so you see a jump. A turn by itself does not imply slowing down, a reversal, or disappearance—those would require additional changes to speed, a 180-degree change in direction, or removal of the track segments. The abrupt repositioning from the frame-boundary turn is why the track appears to jump.
