Subsystems

Subsystems are where methods are created and defined. They're organized by the part of the robot they're for (elevator, LimeLight, shooter, etc.)

To create a new subsystem:

  1. Right-click on the subsystems folder.
  2. Go to the bottom of the context menu that appears and select "Create a new class/command".
  3. In the input box that appears at the top, type/click Subsystem (New).
  4. Give it a relevant name.
  5. Open RobotContainer.java and scroll down to where it says // --- Subsystems --- \\.
  6. Below the other subsystem declarations, type private final NAME VARNAME = new NAME();, where NAME is the file name you gave your subsystem and VARNAME is a new name to reference in code. If applicable, add any required parameters in the parentheses.

To add methods to a subsystem:

  1. Open your subsystem's file.
  2. Go to the very bottom of the file (just before the last bracket) and hit enter a couple of times. Then add a new method:
  3. Type public. This will allow the method to be used outside of the subsystem file.
  4. Type void if the method won't return a value. Otherwise, enter the data type you want the method to return.
  5. Type your method's name, then immediately afterwards, type a set of parentheses. ()
  6. Inside the parentheses, add your parameters -- inputs that are passed into the method as premade variables. Like normal variables, you need to provide the data type and a parameter name.
  7. After the parentheses, type a { and press enter. This is where you'll write your method's code. In VSCode, a } should automatically appear where it needs to be.

To call subsystem methods:

These methods shouldn't actually be run within the subsystem files, only defined. That's what commands are for.
