GeneralPath 未按更改比例绘制
我目前正在制作一款横向卷轴游戏，该游戏使用随机生成的地形在后台滚动。地形基本上是 GeneralPath 类的一个实例。当地形生成时，角点 (0, 0) 和 (width, 0) 包含在路径中，因为查看画布的高度尚不清楚。为了使地形显示为正面朝上，我添加了以下几行代码：
g.translate(0, getHeight());
g.scale(0, -1);
这应该将坐标系翻转为笛卡尔格式，左下角为 0, 0。 由于某种原因，地形没有绘制。当我注释掉这些行时，它可以工作，但是是颠倒的。如果我只注释掉缩放命令并将翻译量更改为较小的数字，它也会成功绘制（颠倒并翻译少量）。
提前致谢！
Im currently making a sidescroller game which uses randomly generated terrain that scrolls in the background. The terrain is basically an instance of the GeneralPath class. When the terrain generates, the corners (0, 0) and (width, 0) are included in the path since the height of the viewing canvas isnt known yet. To make the terrain appear right-side-up, i added the following lines of code:
g.translate(0, getHeight());
g.scale(0, -1);
This should flip the coordinate system into Cartesian format with the bottom left being 0, 0.
For some reason, the terrain isnt drawing. When i comment-out these lines, it works, but is upside-down. If i only comment out the scale command and change the amount translated by to a smaller number, it also draws successfully (upside-down and translated a small amount).
Thanks in advance!

正如您所注意到的，您还需要缩放 x 轴 - g.scale(1, -1);
As you noticed, you need to scale the x axis as well - g.scale(1, -1);
