其原理很简单，我们克隆了一堆立方体到一个数组，然后使用这些发出我们的粒子。由于立方体的几何性质，我们得到在我们的屏幕上流动的粒子一个漂亮的网格，在几个1和0的增加，我们已经创建了自己的二进制网格的X粒子。
The principle is simple, we clone a bunch of cubes into an array and then use these to emit our particles. Due to the geometric nature of the cube we get a nice grid of particles flowing across our screen, add in a few 1′s and 0′s and we have created ourselves a binary grid with x-particles.
