Could someone guide me on how to stop overlapping the bubbles and also It should work like a
windows 8 bubble screensaver.

Any help would be sincerely appreciated..

推荐答案

你需要检查两个气泡坐标之间的欧氏距离是否小于或等于两个气泡的半径之和（=一个气泡的直径，如果它们都是相同的大小）。

You will need to check if the Euclidean distance between the two bubbles' coordinates is less than or equal to the sum of the radii of the two bubbles (= diameter of one bubble if they are all the same size).

var deltax = b1.x - b2.x;
var deltay = b1.y - b2.y;
if (Math.Sqrt(deltax * deltax + deltay * deltay) <= b1.radius + b2.radius)
{
  // the bubbles collide
}

这假设坐标是气泡的中心 !!
