* Delay switch to new server until after JoinGame is sent.
Unfortunately, in some cases (especially vanilla Minecraft) some login
disconnects are sent after ServerLoginSuccess but before JoinGame.
We've been using ServerLoginSuccess but it has caused too many problems.
Now Velocity will switch to a stripped-down version of the play session
handler until JoinGame is received. This handler does very little by
itself: it simply forwards plugin messages (for Forge) and waits for the
JoinGame packet from the server.
This is an initial version: only vanilla Minecraft 1.12.2 was tested.
However this is the way Waterfall without entity rewriting does server
switches (which, in turn, is inherited from BungeeCord).
* Move to Gradle 5 and Error Prone.
Velocity now resolves plugin dependencies using a depth-first search
(DFS), instead of using Kahn's algorithm like before. This properly handles duplicate indirect dependencies.
Thanks to @creeper123123321 for noticing this issue!
If a server with the same ServerInfo is attempting to be re-registered,
we will return the existing registered server, which is less surprising
behavior than before.
This interface roughly maps the BungeeCord ServerInfo API. Accordingly,
this is a breaking API change, as many of the server-related events and
methods working with server info instances now provide/expect the
RegisteredServer interface instead.
- Add plugin (display) name and plugin URL
- Make everything except plugin ID optional (instead of empty string)
- Exclude empty properties from generated velocity-plugin.json
- Make plugin author list immutable
- Other (minor) cleanup and refactoring
The Velocity API has had a lot of community input (special thanks to @hugmanrique who started the work, @lucko who contributed permissions support, and @Minecrell for providing initial feedback and an initial version of ServerListPlus).
While the API is far from complete, there is enough available for people to start doing useful stuff with Velocity.
Changes in StateRegistry will allow to us skip packets decode which we don't want handle in BackendPlaySessionHandler for a specific versions
Also do not handle respawn packet
