    DropChest - Chests that absorb dropped items
    Version 0.8.2
    Important! When migrating from 0.6 to any above version, you have to move the DropChest.txt from server/plugins/DropChest.txt to server/plugins/DropChest/DropChest.txt
    This is because I have to follow the Bukkit plugin saves guidelines.

    This plugin automatically adds dropped items to near chests. That is very useful for automatic farming and monster traps that gather loot.
    • automatically suck dropped items that are near a chest to that chest
    • customizable warning if the chest is nearly full
    • list your DropChests and watch how much percent is still free
    • Permissions
    • Filter
    • Storage Minecart support
    • Dispenser and Furnace support
    • Item information
    • Chest protection
    • Automatic Owner tracking
    • Double-Chest support

    Show commands (open)

    To add a chest to the "watchlist", type
    /dropchest add [radius]
    After that, rightclick the chest that you want to add. Radius is the radius in which the Chest should suck items. Default value is 2.

    To remove a chest from the "watchlist", just type
    /dropchest remove chestid
    where chestid is the number of the chest that you get when you call /dropchest list

    You can list the chests that are on the watchlist via
    /dropchest list
    You can adjust the radius of a chest via
    /dropchest setradius chestid radius
    You can check which id and radius the Chest in front of you has:
    /dropchest which
    after that, rightclick on the Chest to get information about it.
    If you are sitting in front of the console, or don't want to rightclick, you can use
    /dropchest info chest
    It will generate the same output as /dc which.

    You can teleport to a chest via
    /dropchest tp chestid
    where chestid is the ID of the dropchest

    You can set the name of a DropChest via
    /dropchest setname {chestid} {newname}
    The name is displayed in chest is full warnings, and in the DropChest list!

    If you migrate from 0.6 to 0.7, you can set the owner of a dropchest by typing:
    /dropchest setowner {chest} {newowner}
    You can protect a chest by typing
    /dropchest protect {chest} {on|off}
    You can always use /dc instead of /dropchest if you are lazy.

    Another very helpful command is /dcitem:
    /dcitem [NAME|id]
    This can be used to obtain the name of an item by it's id or get an id of the item-name.
    This doesn't work with all names, though.

    Use the new command /chestinfo {name|id} to get info about what's inside the chest.
    Omit the argument and rightclick on any chest to get info about that.
    >/dcitem 4
    >/dcitem cobblestone

    Show Configuration (open)

    You can configure DropChest by pasting the contents of the following block to plugins/DropChest/dropchest.cfg
    #Should the dropchest drop items when it gets a redstone signal?
    #How long should the dropchest not suck items after it has dropped them
    #Should users be able to protect chests like in LWC?
    #Which is the default radius if you omit the radius argument in /dropchest add?
    #Which should be the maximum radius for players that have not dropchest.setBig and aren't ops?
    #At which fill-status should the chest warn you?
    #Which message should appear as warning?
    #You can use this variables (example):
    # $owner : the owner of the chest (narrowtux)
    # $name  : the name of the chest (my superduper mobtower chest/#42)
    # $fill  : The fill status, in percent (81)
    warnmessage=$owner, your chest $name is nearly full($fill%).

    Filter / Storage Minecarts
    Show Filter/Storage Minecarts (open)

    Filters have changed in version 0.6. There are now 3 seperate filters that are for sucking items, pulling items from passing minecarts and pushing them to passing minecarts.
    You can now set the filters by either using commands or using the interactive mode. Let me show you the interactive mode first:
    to begin, type
    /dropchest filter {suck|push|pull}
    Note: choose one of suck, push or pull, please (for example /dropchest filter suck)
    Then you will enter the interactive mode. In this mode you can edit the selected filter by hitting the chest with the desired item in your hand.
    To edit another filter, type the above command again.
    To finish your filter, type
    /dropchest filter finish
    Commands mode:
    /dropchest filter {suck|push|pull} {chestid} {itemid|itemtype|clear}
    Call the filter-command like above, as second argument, use the chest-ID, and as third argument, either type the item-ID, the name of the item (as they appear here: org.bukkit.Material) or type clear to clear this filter.
    Please note! The suck filter acts different from the Pull/Push-Filter when it's empty. When the suck-filter is empty, the chest will suck every item. When a Pull/Push filter is empty, it won't take or give any items to a passing minecart.

    Show Permissions nodes (open)

    You can use these nodes:
    • dropchest - To get the right to use DropChest
    • dropchest.create - To call /dropchest add
    • dropchest.remove - To call /dropchest remove chestid
    • dropchest.radius.set - To set the radius of a Chest to something else than 2
    • dropchest.radius.setBig - To have unlimited radius
    • dropchest.which - To have access to the /dropchest which command
    • dropchest.teleport - To be able to teleport via /dropchest tp chestid
    • dropchest.filter - To set or reset filters
    • dropchest.filter.set - To set filters in interactive mode
    • dropchest.filter.reset - To reset filters in interactive mode (click with nothing in hand)
    • dropchest.list - To have access to /dc list and /dc info
    • dropchest.destroy - To be able to break a dropchest without removing it before.
    • dropchest.protect - To be able to protect a chest
    • dropchest.moderator - To be able to modify a dropchests properties even if you're not the owner. Also, ops and the console can do that.
    You can use these variables:

    • dropchestmaxradius - To adjust the maximum radius for a group or a user
    How to use variables:

          dropchestmaxradius: 1000
    This is just an example and this also works with groups!

    I have a question. Currently the collection point for my mob tower is over 25 blocks from the killing zone of the tower. Do the chests collect drops only when they are dropped, or when they enter the watch zone. Let me explain a little more. My drops are being sent to a single point some way away from where the mobs get killed. Do I need to put these chests near where the mobs get killed, or will they pick up the drops as they move down the conveyor (water channel)

    Edit: Obviously I haven't tried it, my server operator is planning to put this mod on his server when he can.

    Edit2: And can the chests suck drops through walls?
  3. Offline


    I can attest that it will pick up drops as they move down a water conveyor. It seems to basically run a timer and if something is near the chest when that timer does it's sweep, it will put it in the chest. That timer seems to be pretty frequent. I have a monster spawner set up to drown monsters and then sweep their loot towards a gutter with a chest in it. It will pick them up once they're close enough.

    Not certain about through walls, but I imagine it does. It would be MORE code to check if walls were in the way. Simpler to just check if it's in range.
  4. Offline


    You are right. The Timer runs every second, maybe I'll make that adjustable too. And the chests of course suck items through walls. But it would be a great addition because this would do the plugin more realistic
  5. Offline


    Suggestion, if possible could inventory stack? Items such as Bacon for example. Other then that it still seems like Timer-o breaks at times in 292/302

    mh the dropchest dont work for me with 300+ build

    I'm currently going on with the very current build of both craftbukkit and bukkit. So stay tuned, the bukkit guys have fixed a lot of bugs!
    --- merged: Feb 11, 2011 6:57 PM ---
    I released version 0.2.3
    This also has a maximum radius of 20 which I forgot to mention above
  8. Offline


    thx for update. i will look forward to run it on my server with customizable max radius (like 1 variable setting in config: maxradius=20 + permissions next update ;)

    I currently test a version that should fix the bug with the timer-X exception. You can test it in the download below

    I'm not sure what version bukkit is being used, but have a look at this setup. The second chest does not pick up anything.




    The three chests closest are not dropchests yet. I want them to be though. And even when the first chest is full I've noticed that the other chests stop collecting too.
  11. Offline


    Pardon but I only just now checked that one out! Been running 1 chest for nearly 2 hours now and not a problem so far! I will try to give multiple chests a go a little later. I'd still like to see a Permission build + config so we could allow different groups different ranges- Or a simple Force 2-10 range for users and OP's could potentially set Infinite numbers (again, Permission driven).

    Filter would also be absolutely awesome!

    Either way, Really nice work Tux! I really like this :)

    Thank you, but this version also has a bug, I think. I suppressed the exception well and if there is an exception, the timer continues, but sometimes my algorithm thinks that I broke the Chest and removes the DropChest. I hope you can live with that until I fix it.
  13. Offline


    Don't think I've experienced this yet. The timer is working perfectly now though! But Multiply chests don't work at all right now- They stay active but ignores picking items. Quite happy with it as is (Wish there was a filter though *Chuckles*)
  14. Offline


    @fisherp: which one is the second chest?
    You could also try to restart due to a bug in craftbukkit. Or update Craftbukkit to the latest version, because I think it has been fixed there.
  15. Offline


    Could you make the max radius customizable? (Tho it lets me Dropchest a chest with larger radius's, just not change the radius.)I am using a drop chest for a location im clearing out so my inv doesn't get full, but a 20 radius wouldn't cover it.

    Also a bug I have is the time (like many other people), I run multiple chests and they all just stop working.
  16. Offline


    Version 0.3 is out!
    It has Permissions support and also an adjustable radius for every user.
    Check it out!

    I would suggest you optimize this by storing the squared max distance and then you can avoid the squareroot like this:
    double distance2 = levelDistance*levelDistance+dz*dz;
    return distance2 <= maxDistance2;

    Lol, I started developing this a week ago :S. But someone was first XD.
  19. Offline


    That's a good idea.
  20. Offline


    Ignore my previous post...
    Note this is the same as
    return Math.sqrt(dx*dx+dy*dy+dz*dz) <= maxDistance
    But again to avoid sqrt since that is costly operation, you can store the radius squared and do this optimization:
    return dx*dx+dy*dy+dz*dz <= maxDistance2;

    The left one is chest 1, the right one is 2 (of the ones furthest away)
  22. Offline


    When there is an item beside my chest, I receive errors rather than the item being sucked up by the chest. Anybody know why this is?
  23. Offline


    What error message is it exactly?
    --- merged: Feb 12, 2011 10:15 PM ---
    In version 0.3 I also worked around this bug.
  24. Can it be, that it doesn't work in other worlds?
    I have 2 worlds, in the normal World it works fine, in the second world the chest doesn't sucked dropped items.
  25. Offline


    Yeah, I didn't implemented support for multiple worlds now.
  26. Offline


    The message just says "Warning! An error occured!"

    Also is there a way you could make this work for storage minecarts? I would love to be able to just get a minecart down the track to my mob grinder and get the items coming back to me.

    First of all... nice idea m8.

    Anyhow I recieve the following error when starting my server with the DropChest plugin:

    I think, you don't have Permissions installed. It's required for running DropChest.

    not sure if this is the right place to go for this but why not..

    drop chest on death.

    I want a chest created and filled with my items when I die, (if I have items to drop and have a chest in inv)
    only place chest if no other chest is within x blocks. say 20 or so.
    this chest is to be locked automatically with lwc -c private. (optional)

    The idea being that as people explore and die they dont always go back to get their things.

    These chests would be nice things for other players to find.

    A friend has told me of exactly the same thing you describe here. I ask him, if he meant that this is already a plugin. Else, I may implement it.
