Could not pass event PlayerMoveEvent to JustAFK v1.3

[bog500]

It usually works fine, but sometimes my console is spammed with this error :

Hi bog,

Due to school I have not been maintaining JustAFK and have not actually updated it since 2013. I expect there are many bugs that go unreported because of this reason. I greatly appreciate you taking the time to open an issue here but I do not have any plans to continue support for this plugin.

I see you have some programming experience so please feel free to fork this repo and perform the fixes you see fit. You may want to add a null pointer check to the onPlayerMove() listener in the JustAFK.java file as indicated by the error you posted:

Caused by: java.lang.NullPointerException
at net.alexben.JustAFK.JustAFK.onPlayerMove(JustAFK.java:216) ~[?:?]
...

While it may not solve the root issue (likely a conflict with another plugin), it will at least clear the error from your console.

Best,
Alex

Hi Alex,

Thanks for your quick feedback. I will fork the code and do some minor changes.

[alexbennett]

Sounds great.

You may also want to check out a fork that a friend of mine made back in August: https://github.com/HmmmQuestionMark/JustAFK

He updated it to the Java 8 JDK and to a more current build of Minecraft as well as included a couple of general updates/fixes.

[bog500]

ok. Any reason why his fork wasn't pulled into this one ? and is the version on dev.bukkit.org this one or his ?

[alexbennett]

No specific reason, I just never got around to pulling it over. He didn't make a pull request either, just simply updated it and I only recently realized it. His version is also newer than the Bukkit Dev version.
