With that structure, you actually don’t need the while loop. It would just go into the driver control loop. Post your code when you can and i’ll take a look.

there’s my coding file i could use all the help i can get tbh

This registers an event handler. It only needs to be done once, and doesn’t need to be put in a loop.

This only works if spin has been called since the last stop or program start. Otherwise, all it does is set the default velocity for any commands that don’t specify a velocity.

so how do i go about it to where it works

Just go to the documentation library on the vex website

You can find all of the commands and what they do here

  • Remove the if statement, the callbacks don’t need to be in a statement/loop
  • Considering your use case, you should change the 'setVelocity’s to spin in your functions.
