    Without testing I can tell it to you: It will freeze the server and eat up one CPU core. It's the same as you have a "bad" (never ending) for/while loop in a plugin. ;)
    Well, maybe it will eat up RAM, too... Hmm, now I want to test it to get sure. :D

    that wouldnt work that plugn :( you havent added the executor to the onEnable and also there is no command to use this command aka no if(cmd.getName().equalsIgnoreCase("something"))
     
  15. Offline

    V10lator

    As onCommand is in the main class: Not needed
    As this only has one command: Not needed.

    Next time try it before complaining. :p

    You can define commands in the plugin.yml, these are auto bound then.

    The purpose of this thread is to show off java in general as well as plugins.
    None of these have a plugin.yml and therefore none will work. All the plugins leave onCommand without registration as that is not the point.

    I don't know if this was directed at me or not ... if not then disregard the following :p

    But I thought the point of this was just to have fun and create something useful and practical, under 50 lines of code.. that's the challenge isn't it? Otherwise everyone would be doing the simple and basically useless
    Code:java
    1. import org.bukkit.*
