Now, to draw a second rectangle on the other side of the screen, maybe in black this time, we can just call our rectangle drawing function.

现在，要在屏幕的另一边绘制第二个矩形，这次可能是黑色，我们可以调用我们的矩形绘制函数。

And it says, " To make the right cloud move as well, try adding a line of code inside the draw function that increments the right X variable by one pixel in each frame."

它说，“要让右边的云也移动，请尝试在绘制函数中添加一行代码，在每帧中将正确的 X 变量增加一个像素。”
