I've sort of solved my problem, but not in a way which really makes total sense. Both of the below fragments work as expectd: #1 if ((SensorValueRaw(1) & SensorValueRaw(0)) != 255) #2 if ((SensorValueRaw(1) != 255) || (SensorValueRaw(0) != 255)) Number two is obvious but rather verbose, number one is just wierd! Since I'm accustomed to Perl which allows extreme lazyness I would have thought that I could just do this: if ((SensorValueRaw(1) || SensorValueRaw(0) != 255)) But that does not work. Is this normal in NQC? Chris"at"superfami"dot"com

Hi Chris, (...) this is a bit crazy, unless your sensor value is a bit pattern. (...) This is sensible, but are you sure it's ok to use equality and not inequalities like SensorValueRaw(1) < 240? (...) but it's equivalent, also in C, where & is (...) (23 years ago, 16-Dec-01, to lugnet.robotics.rcx.nqc, lugnet.robotics.scout)

		How to read the touch sensors on the Scout in NQC?
All, I'm feeling pretty stupid right about now. I've read the NQC docs, looked in the newsgroups, books, etc, but I can't seem to figure out how to read the touch sensors on my Scout. I want to implement a bumper checking task but no matter how I (...) (23 years ago, 16-Dec-01, to lugnet.robotics.rcx.nqc, lugnet.robotics.scout)
