Make a squishy bouncing ball

nanopixel

How to make a ball flatten when it bounces against the walls. Use arcs? Maybe something else? Just wondering, if we use arc, how much to actually 'squish'?

Use this as the base:

int c;
float xPos;
float yPos;
int x;
int y;

void setup(){
  size(600,600);
  xPos = random(50,550);
  yPos = random(50,550);
  x = 1;
  y = 1;
}

void draw(){
  background(0);
  c = color(255,255,255);
  fill(c);
  noStroke();
  ellipse(xPos,yPos,50,50);
  xPos = xPos + 2 * x;
  yPos = yPos + 2 * y;
  if(xPos > 575 ||xPos < 25) x *= -1;
  if(yPos > 575 ||yPos < 25) y *= -1;
}

Just thought about something else. Instead of flattening, maybe turning into an oval would be easier? Not sure.

Hm

Try search on openprocessing.org

My idea would be to calculate 360 dots / ellipses that make up the circle like a swarm (see particles)

Now, when it touches a wall, I dunno

Some stay on the wall..... when the center (invisible) of the big circles touches the wall, it turns, dragging the other spheres with it

like on a chain the small spheres are connected with springs (See examples)

They want to fall back in a certain Position around the Center
