In most of my solutions I go through this routine (with the necessary changes):
| v (red) : Sync -> Start -> Sync -> (blue) : Sync -> Sync -> Start -> ^ |
just to make sure that the blue waldo runs first.
Except for the early research levels, where counting steps is an option, I've always had to do something like this, up to 6 SYNCS at one point, which was not very pleasing!
So, what are the other options for synchronzing the waldos?
Mods: this a cw question, please mark it as such and remove this remark. Thank you!
