Assignment P3

A Random Particle §

// caleb b
// random particle
 
// generate random starting positions for the particle
float particleX = random(0.0, 500.0);
float particleY = random(0.0, 500.0);
 
void setup() {
  size(500, 500);
  
  frameRate(24);
}
 
void draw() {
  background(100, 100, 100); // erase everything
  ellipse(particleX, particleY, 20, 20); // draw the particle
  // adjust the particle's position
  particleX += random(-5, 5); 
  particleY += random(-5, 5);
}

Many Random Particles §
