Yes, you are correct. Setting both a jag and a victor look like the following:
Code:
myVictor.Set(0.5);
myJag.Set(0.5);
Where the parameter is a floating point number between -1.0 and 1.0.
Whenever you don't know which function to call, take a look at either the
WPILib source code or the
doxygen documentation. It will tell you which classes can run what.
