Auton Visualizer

Move a waypoint.
Let the code follow.

A VS Code extension that turns VEX autonomous routines into a route you can see and edit. Drag a point on the field, and the coordinates update in your C++ file.

The idea

An autonomous routine is a series of coordinates, but it’s hard to picture a robot’s path by reading numbers. Auton Visualizer brings the field into the editor, so the route and the code can sit side by side.

How it works

  1. Read the route

    The extension finds waypoints in calls such as moveToPoint, moveToPose, and setPose, then groups them by routine.

  2. Adjust it visually

    Drag a waypoint to a new position. The extension edits the matching coordinates in the source file through the VS Code API.

  3. Keep both views together

    Changes to the C++ document refresh the visualizer. The path stays connected to the file you’re working on.

A small loop

Open a C++ routine, run Start Auton Visualizer from the command palette, and adjust the route alongside your code.

The visualizer helps edit waypoint positions. Testing the routine on the robot is still part of the process.
