Creating field for integer input

Processing Coding Questions

Could you please guide me where to look for creating a field to enter integer/digits in processing? Would appreciate your help!

Here’s a somewhat crude example, if not using a library. You could also look into that, like G4P, ControlP5 or others.

String inputText = "";
String message = "Click mouse here and type a number: "; 
int inputValue = 0;
boolean typingSomething = false;

float x = 50;
float y = 50;

void setup() {
  size(500, 500);
  textSize(16);
}
 
void draw() {
  background(32);
  fill(200);
  text(message + inputText, x, y);
  text("You entered  : " + inputValue, x, y+20);
  
  
  if (mousePressed && mouseButton == LEFT) {
    if (mouseX > x && mouseX < x+textWidth(message) + textWidth(inputText) + 10) { // a tad wider area
      if (mouseY < y+textDescent() && mouseY > y-textAscent()) {
        typingSomething = true;
        inputText = ""; // reset
      }
    }
  }

  // Blinking text cursor
  if (typingSomething) {
    if ((millis()/500)%2 == 1) stroke(color(255,200,0)); else stroke(32);
    float cx = x + textWidth(message) + textWidth(inputText);
    line (cx, y+textDescent(), cx, y-textAscent());
  }


}
 
void keyPressed() {
  if (typingSomething) {
    switch(keyCode) {
      case BACKSPACE:
        if (inputText.length() > 0) {
          inputText = inputText.substring(0, inputText.length()-1);
        }
        break;
      case DELETE:
        inputText = "";
        break;
      case ENTER:
        inputValue = parseInt(inputText); // Arguably less confusing than just int(string)
        typingSomething = false;
        break;
      default:
        if (keyCode != SHIFT && keyCode != CONTROL && keyCode != ALT) {
          inputText = inputText + key;
        }
        break;
    }
  }
}

Even shorter (I forgot where I found this):

String myText = "Type something";
 
void setup() {
  size(500, 500);
  textAlign(CENTER, CENTER);
  textSize(30);
  fill(0);
}
 
void draw() {
  background(255);
  text(myText, 0, 0, width, height);
}
 
void keyPressed() {
  if (keyCode == BACKSPACE) {
    if (myText.length() > 0) {
      myText = myText.substring(0, myText.length()-1);
    }
  } else if (keyCode == DELETE) {
    myText = "";
  } else if (keyCode != SHIFT && keyCode != CONTROL && keyCode != ALT) {
    myText = myText + key;
  }
}

Great Raron! Thank you very much! Let me try with the codes you posted. Will update you further
