ns-3使用animation出现文件小、无时间、打开后只有拓扑没有内容

 ns3的官方手册很全，相关书籍也是有的，官网先贴在这里：

ns-3使用animation出现文件小、无时间、打开后只有拓扑没有内容——正常100K的xml，只有10几k，所以添加logging查看问题。

使用以下内容打开animation信息

LogComponentEnable("AnimationInterface", LOG_LEVEL_DEBUG);

发现如下的打印

可以看到

后面也没有正常的

推测是AnimationInterface anim("Liuthird.xml"); // Mandatory位置不合理，导致在start之后，立刻就结束了，把原来放在

if (tracing)

{}
里面的AnimationInterface anim("Liuthird.xml");放到外面就可以了，尝试把AnimationInterface anim("Liuthird.xml");框到if(1){}里面，仍然不行。
