Leave footprints in snow that fill in under new snowfall, one per stride

A trail of footprints tells the player who walked here and when. Prints stamped once per frame bunch up when the game is slow and leave gaps when it is fast, and prints that never fade make a snowfall look painted on. Here is how to space them evenly and let the weather slowly erase them.

Why this works

A trail should be laid by distance walked, not by frames drawn, or a fast computer would leave more footprints than a slow one. Carrying the leftover distance forward keeps every step evenly spaced, and falling snow fills each print in over time.

When not to use it

Don't use it when footprints are a clue the player must find later, such as tracking an animal or a culprit. Fading ones would erase the evidence, so keep them until a clear event wipes them.
