Network.TestConnection how to?

Unity Engine
1

Hi,

I’m currently trying to figure out just how Network.TestConnection works. The thing that confuses me the most, is that we are able to set Network.connectionTesterIP and Network.connectionTesterPort.

So I though, if I want to test my Network capabilities, I just set connectionTesterIP as 127.0.0.1 and the port to the one I want to open up if I create a server. However, when I do this, I always get Undetermined in Network.TestConnection. And what confuses me more (maybe it is a bug?), if I try again to determine the network capabilities without setting the IP and Port (like it is on the example in Network.TestConnection documentation) I always get Error. In order to make it work again, I have to close unity and relaunch it.

So, basically, when should I use connectionTesterIP and Port? When I want to get info about a server that is not registered with MasterServer (i.e. direct ip connection)?

Regards,
Afonso

When Unity tests the connection to a specific server, the server must already be running (if I remember correctly).
So before starting the test, start the server.

You can run the connection test any time, no need to start a server.
The connection tester runs on the same IP as the master server and just helps to establish, from outside, whether you are on a public/private IP and if you are NAT punchable.
