Using two different readStringUntil "characters"

Processing Electronics (Arduino, etc.)

@GoToLoop I have tried and tried and even copied the code on the links you gave as though it was a template, but I have gotten nothing

I did, however, watch a video about multiple serial values and acting on it. After watching it I got this:

import processing.serial.*;

Serial port;

int index = 0;
int[] input_arr = new int[2];
int px, py;
int x, y;

void setup() {
  background(0);
  size(500, 500);

  port = new Serial(this, "COM12", 115200);
  stroke(255);
}

void draw() {
}

void serialEvent() {
  while (port.available() > 0) {
    String raw = port.readStringUntil('\n');
    input_arr[index] = int(raw);
    index++;

    if (index > 1) {
      x = px + input_arr[0];
      y = py + input_arr[1];
      port.clear();
      println(input_arr[0]); //debug; this doesnt print anything
      px = x;
      py = y;
    }
  }
  line(x, y, px, py);
  port.bufferUntil('\n');
}

I might start a new thread about this specific one…
