I'm wondering how to eliminate, or at least reduce as much as possible, the "depth of grind." Ideally, I want to achieve two states: either the cycle has touched and layed its wall up against another wall, or not. If a cycle's progress is stopped by rubber at a wall, that should be that, the end, no getting behind it no matter what. Even if cycle_rubber is 10, and I use 1 to make the initial grind, and you use 9.9, you shouldn't pass under.
Is this possible? I've fooled with several settings, but nothing I've tried accomplishes this.
The immediate application is for a new server on which sinewav and I have collaborated, called "Adventures of TRON: Original Arcade." Check it out.
However, I've wondered if this is possible for a long time, before this server ever came up. If it's doable, maybe some other folks will adopt it.
