P3D collision

Targmann

How would I make collision with boxes in P3D, using the Queasycam library?

I mean collision between you and the boxes, so that you hit the boxes instead of going through them. Here's my code:

import queasycam.*;
QueasyCam cam;
float x, y, z;
float s;
void setup() {
  size(1280, 904, P3D);
  x = 100;
  y = 100;
  z = 0;
  s = 0.1;
  cam = new QueasyCam(this);
  cam.speed = 10;
  cam.sensitivity = 0;
}
void draw() {
  background(151, 212, 247);
  noStroke();
  lights();
  directionalLight(200, 200, 200, 0, 100, 0);
  translate(width/2, y-470+(width/2), z);
  rotateX(361.26);
  // World

  // Stone
  for (float i = -1000; i<1000; i+=100) {
    for (float j = -1000; j<1000; j+=100) {
      stoneBlock(i, -100, j);
    }
  }
  // Grass
  for (float i = -1000; i<1000; i+=100) {
    for (float j = -1000; j<200; j+=100) {
      grassBlock(i, 0, j);
    }
  }
  for (float i = -1000; i<1000; i+=100) {
    for (float j = 400; j<1000; j+=100) {
      snowBlock(i, 0, j);
    }
  }
  // Snow
  snowBlock(-1000, 100, 900);
  snowBlock(-1000, 200, 900);

I'm trying to remember -- does the QueasyCam FPS example sketch already have collision detection in it?
