> How can I use **thread()** function correctly in this kind of situation?

You can’t, b/c its signature is parameterless & `void`. ⛔

Instead, you can create a `class` which `extends` Thread: 🧵

void setup() {
  noLoop();
}

void draw() {
  background((color) random(#000000));
}

void mousePressed() {
  new ThreadedMethodWithIntParameter((int) random(100));
}

class ThreadedMethodWithIntParameter extends Thread {
  final int input;

  ThreadedMethodWithIntParameter(final int inp) {
    input = inp;
    start();
  }

  @Override void run() {
    println(input);
  }
}
