For the Processing sketch, I wanted to continue using particle systems in the hopes of creating an architectural composition. I have always been captivated by the VFX effects like shattering and collisions. Thought I could replicate a similar effect by having a program that drew lines between particles as soon as it verified that they were in the vicinity of one another. The way I achieved this was by making a function that verified the distance between two particles, where s in a arbitrary distance number of pixels, in the case of my script, 10 pixels.<\/p>\n
void detectCollision(Particle p) {
\nif (PVector.dist(location, p.location) <= p.s\/2) {
\np.velocity = new PVector(0, 0);
\np.stopped = true;<\/p>\n
In the main draw cycle, everytime the framecount is divisible by 10, a mouse press triggers the creation of a particle. A line will be drawn between two particles as soon as the distance between the particles is s\/2. Note that this results in the ridges usually seen when something shatters.<\/p>\n
for (int u = 0; u < particles.size(); u++) {
\nParticle p2 = (Particle) particles.get(u);
\np.detectCollision(p2);
\nif (PVector.dist(p.location,p2.location) <= p2.s\/2)
\nline(p.location.x, p.location.y, p2.location.x, p2.location.y);<\/p>\n
