I ran mine last night at a "family science night" for a school. Big hit,
although I *absolutely* need error checking in my code (playing against a robot
is easy - playing against a 5-year-old, with a couple of 4-year-olds constantly
hitting the "move completed" button, now that's hard...). Ironicly, two people
beat it - time to tune up the code to deal with really stupid,
nobody-would-ever-do-THAT type moves. Sigh...

Ironicly, I had been thinking about switching to rotation sensors, before the
mass exodus in the other direction. I think at the first meeting mine was the
only one using touch sensors this way.

The first thing I don't understand is why you seem to be watching the event
("scancomplete") in a tight wait loop ("wait until scancomplete"). In NQC (and
the basic firmware), there's a special way of monitoring an event that gives
very prompt (immediate) response. I'm not sure if you are invoking this ability.

But that means for every cell scanned, you've added a 1/2 sec pause. I wish I
knew the answer to your original question, but at least put the 1/2 sec wait
after the "set scandone = 1" within the "If A = 1" statement. That way it only
executes the (time-wasting) pause if it has found a block.

Now I'm really confused. In the code fragment you posted, CurX & CurY are
*immediately* both set to zero if a block is found. Are you talking about some
other variables?
