How To Code a Toggle
This post talks about how to code a toggle in VEXCode:

VEXCode V5 Pro Toggle Control

First, we must identify and have a fire-once trigger: //Create buttonPressed variable to be used bool buttonPressed = false; while (true){ bool buttonA = Controller1.ButtonA.pressing(); //Check if button A is pressed and buttonPressed is false if (buttonA && !buttonPressed){ // We then set buttonPressed to true // This makes it that this scope (code in curly brackets) // Is ran once and only once when you press the button buttonPressed = true; …

From that, the toggle code is as such:

  bool toggleEnabled = false; // two-choice toggle, so we use bool
  bool buttonPressed = false; // IGNORE, logic variable

  while (true){
    
    bool buttonA = Controller1.ButtonA.pressing();

    ////////////////////////////////////////////////////////////////////
    // Toggle Logic
    if (buttonA && !buttonPressed){
      buttonPressed = true; 
      toggleEnabled = !toggleEnabled;
    }
    else if (!buttonA) buttonPressed = false;

    ////////////////////////////////////////////////////////////////////
    // Code For toggle Enabled or Disabled
    if(toggleEnabled){
      // Do another thing
    }
    else{
      // Do initial thing
    }

Here’s some sample code while(true){ //If button up pressed, activate if( Controller1.ButtonUp.pressing() ) { piston.set( true ); } //Otherwise don’t activate else { piston.set( false ); } wait(20,msec) }

piston.set( true );

and

piston.set( false);

Putting it all together

  bool toggleEnabled = false; // two-choice toggle, so we use bool
  bool buttonPressed = false; // IGNORE, logic variable

  while (true){
    
    bool buttonA = Controller1.ButtonA.pressing();

    ////////////////////////////////////////////////////////////////////
    // Toggle Logic
    if (buttonA && !buttonPressed){
      buttonPressed = true; 
      toggleEnabled = !toggleEnabled;
    }
    else if (!buttonA) buttonPressed = false;

    ////////////////////////////////////////////////////////////////////
    // Code For toggle Enabled or Disabled
    if(toggleEnabled){
      piston.set(true);
    }
    else{
      piston.set(false);
    }
