Oval collision detection not working properly

Question

So I\'m trying to implement a test where a oval can connect with a circle, but it\'s not working.

edist = (float) Math.sqrt(
    Math.pow((px + ((pwidth/2) )) -          


        

Answer 1

Is using ovals an absolute requirement? You can approximate collisions between fancier shapes by representing them with multiple circles. That way you can use very a simple collision detection between circles and still achieve a high level of accuracy for the viewer.

collision(c1, c2) {
  dx = c1.x - c2.x;
  dy = c1.y - c2.y;
  dist = c1.radius + c2.radius;

  return (dx * dx + dy * dy <= dist * dist)
}
