Surface friction differences
Surfaces change sliding, braking or traction. Identical inputs produce different stopping distances and turning behavior.
The player's decision
Brake on rough ground early or slide on ice and countersteer later?
Original scenario
Original setup: push a crate toward a target across rough ground then ice. Releasing input cannot stop it immediately.
Start with this prototype
Build two surfaces and one movable object with push, counter-push and restart. Show velocity and stopping position. Stop inside the target; vary friction without adding wind or slopes.
Change one variable
Change ice drag alone and measure coasting distance, not just surface color.
What to observe in a playtest
Do parameters update at boundaries, and do stopping distances match at 30 and 60 fps?

Original analysis · version 1
Common pitfall
Keeping ice parameters after leaving it or applying fixed per-frame drag creates inconsistent control.
Observations and sources
Cases refer to public documentation. Developers and community wikis are credited separately; document review is not a claim of hands-on testing.
- SuperTux
Project documentation defines ice as a tile property altering slippery collision behavior.
- Trackmania
The official preview describes dirt, ice and special surfaces changing handling.
