(...) It's a good plan, but I don't think that's the right command. If someone was calculating the position of a line to draw it may well start or end off-screen in the negative values. How about hijacking the FileOpen command, and apply URL-type (...) (18 years ago, 20-Feb-07, to lugnet.robotics.nxt)

| | Wait for Sound: Tone
|
|
Given: The Sound block can play a tone. What would it take to create a "Wait for Tone" block or to modify the "Wait for Sound" block to perceive a tone? I think a "Wait for Tone" block would help ease the transition to learning about communications (...) (18 years ago, 20-Feb-07, to lugnet.robotics.nxt)

The code is working right well! But i think the stall control at the end o each task has no meaning there, since the until loop does not let the script reach it if the motor become staled. (...) Patrick (18 years ago, 19-Feb-07, to lugnet.robotics.nxt)

John, (...) It worked just as I expected. The two motors now are rotating the same time. Thanks to your example, now I am giving some time to understand this setOutput call, and reading all the documentation (it is quite easier with pratical (...) (18 years ago, 19-Feb-07, to lugnet.robotics.nxt)

(...) Or maybe just wrap the calls inside a mutex, so at least the behaviour is defined, if not optimum. Many of the NBC/NXC macros do exactly that, maybe all of them should? ROSCO (18 years ago, 19-Feb-07, to lugnet.robotics.nxt)
