The Ping class of unity uses

1. Purpose

1.1 Get ready ping The Internet , See if you can ping through ,ping Pass means that the network link is normal

2. Reference resources

2.1

Unity And Ping Class analysis & Try to use _ Chen yanbixing's blog -CSDN Blog

3. Be careful

3.1 It is not easy to use ,

1. Obviously can ping through , But it shows that ping no
2. There are no variables in it whether ping Tong ,
3. ping_zhuJi.time=-1 ms , In fact, computers can ping through ,

The code is as follows

1. ping_zhuJi.time Mainly with this and 0 Compare and judge whether it is linked
