Solved Communicate with RemoteToolkit

Hi there.
I have a plugin for a custom gamemode.
When the game is over the server has to restart.
How can my plugin tell remoteToolkit that the server has to restart?

UPDATE: The final result is that I can use getServer().shutdown(); to stop it and remote toolkit will restart it automatically.

Please help.

Please only bump once every 12 hours.

 

Have you tried looking inside the plugin.jar, there might be a method you can call in there that does the trick. Or alternativly use the UDP protocol to connect to the server itself and send "COMMAND:userassword" like in the docs http://drdanick.com/wiki/index.php?title=Legacy_Release_10_documentation#From_an_iOS_device

 

Ok. Sorry

Timatooth Well, I've seen the RTKInterface class in the api javadocs.
But how can I call the methods in this class?
I couldn't find the class in the RTKPlugin.jar or whatever it is called.

I think the interface is used for extending the functionality of the RTK plugin, not interacting with it i.e calling methods.
It looks like you might be left with just making a mini UDP/Telent class that sends the commands just like any other client software does (doesn't seem right) surely there is a better way.

From brief skimming of code I think that's how the JSONAPI plugin does it https://github.com/alecgorge/jsonap...inecraft/jsonapi/McRKit/api/RTKInterface.java

It's can do these methods via its HTTP api

• void remotetoolkit.rescheduleServerRestart(String)
• void remotetoolkit.restartServer()
• void remotetoolkit.startServer()
• void remotetoolkit.stopServer()

 

Timatooth Oh... ok.
But would it actually be possible to simply do an severe output?
Because remote toolkit automatically restarts the server when a severe output is done isn't it?
So could I do something like this?

Code:

public void restartServer(JavaPlugin plugin) {
    //Doing severe output
    plugin.getLogger().severe("Doing a severe output to force a restart.");
}

 

Ha ha that's one way to cheat and do it! You might have to throw a mock exception rather than just logging a message as Level.SEVERE and let it go uncaught to notify bukkit assuming that's how RTK might 'see' them I'm not sure.

 

Timatooth Do you mean, I should throw something like a simple NullPointerException?
Or would it be enough to throw a "new Exception()" ?

 

You can always hook into the plugins on the server and access the public methods/variables.
For exampel, here is an old file that hooks into WorldGuard:
https://github.com/Chilinot/MyChunk...emanuel/mychunkplus/utils/WorldGuardHook.java

MyChunk:
https://github.com/Chilinot/MyChunk...casemanuel/mychunkplus/utils/MyChunkHook.java

 

LucasEmanuel But I need to restart the server. So I need to communicate with the wrapper.
And in the RemoteToolkit plugin there are no API methods.

 

I don't see how this helps. In these cases its quite easy to hook into when there is a open api present. I can't even find the source code for RTK I think it's closed/dev hasn't pushed code but a repo is there.

It feels 'wrong' but I think you would have to come up with a way to create a NPE. Any method that has an explicit throw new Exception(); in Java has to be surrounded in try/catch blocks for it to compile.

Being me, I'd just use the java.io package and wire up some local UDP connection to issue the shutdown. I don't think it would be too hard.

 

Well the plugin doesn't need to have an API in order to hook into it, but after taking a closer look at RTK, you seem to have to do it the other way

Yea sorry, it was just a little tip. Didn't realise how huge RTK was until now

Timatooth Thank you. I'll try both solutions
Just one more question: In the remote toolkit settings I have to specify a severe-detection-level.
If I throw an Exception would severe-detection-level 1 be enough?

 

Another thought, do you need to call any rtk methods at all? getServer().stop(); will stop the server and won't the RTK automatically start it again?

I haven't really used RTK but I just had a plugin that periodically stopped the server by doing just that. The server was started again by a simple shell script.

Code:

#pseudo command line script
while True:
  echo "Server will start again in 5 seconds. Press CTRL + C to cancel"
  sleep 5
  java -Xms1024M -Xmx1024 -jar craft*.jar
end while

 

Timatooth Haha Yes. That's the easiest way xD
And it doesn't feel as wrong as throwing an exception
Thank you.

 

Although this is solved, I will say there is actually a fully documented library which will allow you to communicate with the Toolkit's UDP API:

http://drdanick.com/minecraft/RTKUDPAPI_R7.zip

As well as the associated documentation: http://drdanick.com/minecraft/mcrdoc

The only issue you may have is that you do need to supply a username and password. Future releases of the toolkit will not require this.
