I have a fairly large and messy network of nodes that I wish to display as neatly as possible.

This is how it's currently being displayed:

First, I tried playing with the layout to see if it could generate a good output automatically.

I have tried many different nx layouts, but they all display similar results. I have also tried answers from all of these stack exchange questions:

How to increase node spacing for networkx.spring_layout

我有一个重力矢量(形式为[r,theta]),我加入了我的球的速度矢量.由于某种原因,球在弹跳后不会返回到相同的高度,而是偶尔慢慢地失去高度.我猜测有一些舍入错误或我正在使用的计算中的某些内容,但我无法隔离问题.

这是我的代码.你需要文件和pygame来运行它.对不起,如果有点混乱.如果你愿意,我可以发表更多评论.

每当球到达最大高度时我都会添加一个标记,所以你们就是我的意思.我希望每次弹跳时球都能恢复到完全相同的高度.

我拿了一些不必要的代码.完整的程序在pastebin链接下.
