Controller Binding Sandbox

Offline practice code that mirrors how FRC Team 2363 (Triple Helix) wires Xbox buttons to robot actions.

You do not need a robot, WPILib, or their full repo.

What to edit

Open src/main/java/frc/sandbox/RobotBindings.java

That file has bindDriver() and bindOperator() methods that look like the real team style:

driver.rightBumper().whileTrue(Subsystems.intake.getDeployCommand());
driver.b().onTrue(Subsystems.drive.getResetHeadingCommand());

Change the button (.a(), .b(), .x(), .y(), .leftBumper(), .rightBumper()) or the command, then run again.

How to run

Terminal

cd controller-sandbox
javac -d out src/main/java/frc/sandbox/*.java
java -cp out frc.sandbox.Main

VS Code / IntelliJ

Open the controller-sandbox folder and run the Main class.

Practice ideas

1. Make B deploy the intake instead of the right bumper.
2. Move reset-heading to Y.
3. Make operator A spin the feeder forward.
4. Bind the same button twice and see what happens when you press it.

Files (you mostly ignore these)

File	Role
RobotBindings.java	Edit this — button → action wiring
Main.java	Runs bindings + simulates presses
XboxController.java	Fake Xbox with A/B/X/Y/bumpers
Trigger.java	Fake button with .onTrue / .whileTrue
Subsystems.java	Fake intake / feeder / drive commands
Command.java	Tiny command object
BindingRegistry.java	Simulation helper

Link to the real team code

The real patterns live in Team 2363’s Rebuilt repo, mainly in Robot.java methods like bindXboxDriver and bindXboxOperator. This sandbox keeps the same shape of the code without the full FRC toolchain.
