I just posted how to do X-Arcade Drive here:
It is not coded for Blocks, VCtext, or PROS. It is just the equations and tables to get a feel for what is going on.
If you don’t care about full range joystick operation you can use the base equations. Where the inputs are the joystick values for that axis. If blocks works with +/- 127 ranges for joystick and motor then these are good. If not you need to scale input to output.
LF = VSpeed + HSpeed + Yaw
LR = VSpeed - HSpeed + Yaw
RF = VSpeed - Hspeed - Yaw
RR = VSpeed + HSpeed - Yaw
