stroke weight controlled by mouseWheel

monkeyspasm

Hi guys! I'm very new to processing, and what i'm trying to do with this code, is to simply change stroke weight using mouse wheel. I tried to look for the answers, but couldn't find anything that would help me, and I'm pretty sure, at the end of the day it is going to be a very simple command.

Could any of you help me out?

void setup() {
    size(1000, 500);
    background(168, 100, 168);
}

void draw() {
    noCursor();
    println (mouseX +"," + mouseY);
    noStroke();
    fill(168, 100, 168);
    rect(0, 0, 50, displayHeight);
    rect(0, 0, displayWidth, 20);
    rect(950, 0, 200, displayHeight);
    rect(0, 480, displayWidth, 20);
    triangle(70, 0, 70, 200, 110, 0);
    triangle(130, 20, 90, 220, 130, 480);
    triangle(70, 260, 70, 480, 110, 480);
    triangle(130, 480, 170, 20, 130, 20);
    triangle(190, 20, 230, 480, 230, 20);
    quad(150, 480, 155, 460, 205, 460, 210, 480);
    triangle(160, 440, 200, 440, 180, 220);
    triangle(250, 20, 270, 220, 290, 20);
    rect(310, 20, 20, displayHeight);
    triangle(250, 480, 250, 440, 270, 480);
    triangle(270, 480, 290, 440, 290, 480);
    rect(350, 20, 20, displayHeight);
    rect(390, 20, 100, 440);
    rect(490, 20, 460, displayHeight);

    strokeWeight(20);
    stroke(249, 173, 129);
    line(pmouseX, pmouseY, mouseX, mouseY);
}

Something like this?

float strokeW = 20;


void setup() {
  size(1000, 500);
  background(168, 100, 168);
}

void draw() {
  noCursor();

  strokeWeight(strokeW);
  stroke(249, 173, 129);
  line(pmouseX, pmouseY, mouseX, mouseY);
}

void mouseWheel(MouseEvent e) {
  float amt = e.getCount();
  float newWid = strokeW+=amt;

  // keep it in valid range (>0);
  strokeW = max(newWid, 0);
}
