    Sign Rotate - rotates signs :)
    Version: Check DukkitDev for current version ;)
    while adding signs functionality to bettershop, i got to thinking:
    wouldn't it be neat if they could spin around on their own?
    well, shortly thereafter, here it is:
    a plugin that provides such useless and amusing functionality :)
    to set a sign rotating: run /sr, then click on the sign
    (to stop, click again, to stop setting them on & off, run /sr again)

    rotates signs and skulls! :)
    - delay between each rotation
    - rotate direction
    permissions support:
    - signrotate.create to add/remove rotating signs
    - signrotate.admin to change plugin settings
    saves assigned signs & reloads at start

    /signrotate (sr) toggle sign adding
    /signrotate (sr) cw / ccw change rotation direction
    /signrotate (sr) delay <time> change delay interval (seconds)

    allow wall signs to "rotate" around its block
    iConomy support?
    allow blocks to rotate (not just signs) ?
    - if there is a sign/torch on a face, rotate 4
    - else, rotate 8


    Version 1.0 - 2/6/14
    • Brought back into the modern world!
    • various code optimisations, threw out the old permissions and configs, and in with the new
    • database changed to binary format - uses less disk space, loads much faster!
    Version 0.2 - 7/4/11
    • Sign rotation thread moved to bukkit scheduler (more thread-safe)
      • added groupmanager-specific compatibility
      • permissions 3.x compatible
    Version 0.1.1 - 4/21/11
    • Fixed ConcurrentModificationException annoyance
    Version 1.0 - 4/9/11
    • Initial Release

    unless you provide specific examples and reproducible steps to prove your claim, don't assert that a plugin you tried is causing a "massive memory leak"
    the JVM will naturally collect more memory as it runs, and occasionally runs garbage collection for unreferenced memory if if is using too much memory
    "MASSIVE MEMORY LEAK PROBLEM!" does NOTHING to prove that it does have a problem or to help solve it if there is one

    Works good for me = )

    One little problem is that when u destroy the sing it isnt removed from the configs.

    works fine for me (note: saves on a delay, not instant)
    if you're still having this issue after waiting 30sec, let me know what you did to get that error

    Sorry, should have said more.

    I used a delay time of 0.1 and had 3 signs spinning at once.

    I have tested with no other plugins except essentials.

    Two different things happened: The first one was that the plugin just simply broke, and the server froze. The second thing that happened was that the entire server node died. I could not access my WinSCP or my SSH. Server itself had to be rebooted.

    well, it can be a bit of a resource (cpu) hog when running that fast.. you might have an older machine that shouldn't be trying to run something like this :p
    on a more serious note, i'm sure it could run more efficiently, though.. it is odd how much cpu it uses for a seemingly simple task.. i'll have to look into that
    edit: the cpu usage i saw in testing was the client, not server :/
    not sure why it crashed on you..

    The server hosts are looking into this; possible bug/exploit for java machines.

    Before I install this plugin. Has there been an actual confirmation of the MEMORY LEAK?

    i have not been able to confirm the existence of any memory leaks
    (i also have an old computer as a server, & have had no problems with this running out of memory)

    Version 0.1.1:
    figured out how to avoid errors on modification (wasn't serious, just annoying)

    interesting suggestion.. didn't know about that method
    might add to next release, if i get to playing with it much

    Its not a question of whether you *might* add it. You *need* to add it, creating timer is not the right way of doing things and will cause thread safety issues to all servers who use your plugin.

    The Bukkit scheduler:

    Hi Fella you might be the man i need to chat to im looking for a block to rotate around bit like the sign but from top to bottom and fence could be attached to it i have made a windmill and it would be so cool if this could go around. Any way its just a thought you seam the fella who could pull this off i will keep watching forums, p.s your plugins are great nick work Thanks NickMiner69

    ... odd, i've not had issues with it before..
    haven't got to using the scheduler yet because of a more used plugin i'm trying to finish some updates for :(

    well, finally got around to updating my smaller plugins, so here's that fix that's been on the back burner for a while:
    Version 0.2
    • Sign rotation thread moved to bukkit scheduler (more thread-safe)
      • added groupmanager-specific compatibility
      • permissions 3.x compatible
    hopefully this resolves the issues you've been having..

    Do you think you could also do this with heads?

    ha, that's a fun idea :)

    i shall look into that
