Returning value from keyPressed

Mr_Matten

I need a way to return a value from keyPressed (or some user input from keyboard) stored in a variable and have not been able to find any way of doing so. I would like it to be something like below. I'm new to Processing, but have done a bit of C++, so I am trying to find a way around cin >> from C++.

String keyPressed() { if (key == '\n' ) { saved = typing; typing = ""; } else { typing = typing + key; } return saved; }

You're declaring Processing's keyPressed() callback function w/ a diff. signature!
Please read its reference here: https://processing.org/reference/keyPressed_.html

// the current word you type 
String currResult="";
String saved;
void setup() {
  size(444, 444);
  background(111);
}

void draw () {
  background(111);

  // show the red help text 
  fill(255, 0, 0); // red 
  text("Please type a word and submit it with enter.", 
  20, 60, 
  110, 400);

  // show the input bar and its current text 
  noFill();
  stroke(255);
  rect (10, 115, 170, 20);
  // text 
  fill(255); // white
  text(currResult, 20, 129);
} // func 

void keyPressed () {

  if (key == RETURN || key == ENTER) {
    // submit the finished word to the list 
    if (!currResult.equals("")) {
      saved = currResult;
      currResult = "";
      println (saved);
    }
  }
  else 
  {
    // record the keys (in the current word) 
    currResult = currResult + (key+"");
  } // else
} // func 
//

I think I have figured it out, thanks! I update if anything is amiss :)
