How can you get a joystick to work on a robot on virtual worlds?
How do you move the robot using manually on any of the virtual worlds?

Which platform are you using the Virtual Worlds with (VEX Cortex or LEGO Mindstorms)? Depending on which platform you are using, the programming will be slightly different. However, there is a wiki guide that you can find here (http://www.robotc.net/wiki/NXT_Using_Joysticks) that explains how to use a USB Joystick with Robot Virtual Worlds for LEGO Mindstorms NXT. You can slightly modify that code (change the motor names) to work with the VEX Cortex Virtual Robots as well.

There are also several sample programs (found by navigating to the 'File-> Open Sample Programs -> Remote Control' folder in ROBOTC) that has basic remote control already set up.

Please let us know the specific platform you are using and we will be more than happy to assist you further.

How do you connect a VEXnet joystick to ROBOTC Virtual Worlds- VEX Cortex and Pic 3?
How do you get it to communicate to the virtual world bot?

Hi homtre,
You can't use the VEXnet joystick with RVW. You'll need to acquire a PC joystick. We recommend the Logitech F310 but you can use any PC-compatible game controller.

Cheers,
