Throttle Trouble

Technical Java
1

Hi! I am trying to get our shooter to work with two talons by moving the throttle on the Attack 3 joystick upwards. My code looks right, but is not doing anything. Can any of you guys see anything? Any help would be greatly appreciated! Thanks! :slight_smile:

Are you trying to use the driveTrain on a shooter mechanism? If so, probably not the best way to do it.

Try using throttle.getZ().

Also, since you have a simple robot you should use


#In the operatorControl method
lTalon.set(throttle.getZ())
rTalon.set(-throttle.getZ())

It still does not seem to be working. Do you see anything else weird? I did all that you said.

Your class needs to extend SampleRobot, not SimpleRobot. Iā€™m surprised that even compiles as SimpleRobot is not part of the Java API anymore. Give that a try?
