exiting a yield statement
Hello there,
I have a question regarding exiting a yield statement, after a certain time elapsed. I am changing a global variable according to a keypress (using yield viztask.waitKeyDown) within a function, if that keypress should not happen, I want to exit the yield statement after a certain time interval. And continue the protocol with the unchanged global variable. I might be wrong using yield, and there is some other way (I read about python threading?Running a timer parallel to yield?), could you point me to some example code? I couldn't find this scenario in the tutorial. Thank you. Code:
Step=1 Motion = 15 def control(): global Motion ..... #dosomething with Motion for i in range(1,x) d = viz.Data() yield viztask.waitKeyDown(['y','n'],d) #or, if no key was pressed, after 2 sec exit yield if d.key == 'y': Motion = Motion - Step elif d.key == 'n': Motion = Motion + Step |

Have a look at the viztask.waitAny condition. I believe the example on that page does exactly what you want.
