Overview
| Comment: | Bug fix - Forgetting than list indexes start at 1 Which means I also need to wrap around the list if I get 16 segments. I.e. both 0 rads and 2*Pi rads are valid. This means I probably could have just simply added Pi (previous commit) to reverse the journey as I can just keep wrapping around. Oh well. |

| 12:49 | Commit in haste: Repent at leisure. Fix reverse journey Had not actually tried out my changes, or, it seems, used my brain at all in making them. - Can't simply just add Pi on, need to keep it within 2*Pi limit - Also forgot to get compass direction check-in: 3022ce9541 user: base@atomicules.co.uk tags: trunk, origin/master | |
