When a user is online, you can call him(her) to play!
It's like this:
There will be a button called Quick invite in user screen.
When you click it, it will show a dialog of online users:
+------------------------+
| Ben |
| Sam |
| Pun Master |
+------------------------+
Then just click one(Click Ben), and you should choose your server then:
+------------------------+
| HK01 |
| Strasbourg custom |
+------------------------+
(Click HK01)After that, the other side will show a dialog:
+-----------------------------------------------+
| User Du has called u to play in HK01 |
| Play! Busy! |
+-----------------------------------------------+
If Ben clicked Play! ,then they(we) will goto HK01!
If Ben clicked Busy! ,then in Du's side will show:
+---------------------------------------------+
| Sorry, user Ben is busy |
+---------------------------------------------+
If Ben is installing addons, playing IN ONLINE SERVERS or dont respond in 20s, it will auto choose Busy!
Also u cant choose the same player in 30s(Avoid spamming)(The value can change in conf).
Also in server lobby u can also use the feature but it wont show server selection dialog.
