从右球拍到窗口右侧的距离小于左侧。这些变量的计算是正确的，但仍然不平等。

您已经将窗口设置为800像素的宽度，但其他所有内容都是相对于客户端区域定位的，客户端区域比窗口宽度窄边框的厚度。

使用AdjustWindowRect计算窗口的大小，以便使客户端区域达到所需的大小。

// Initialize a RECT with the size you want the client area to be.
RECT rc = { 0, 0, width, height };
// Now adjust the rectangle to the size the window would need to be.
AdjustWindowRect(&rc, my_style_flags, FALSE);
// Now create the window using the sizes in rc.  Make sure you use
// consistent style flags or the adjustment may not be correct.
const int window_width = rc.right - rc.left;
const int window_height = rc.bottom - rc.top;
my_hwnd = CreateWindow(..., my_style_flags, x, y, window_width, window_height, ...);
