    Because One is never enough!
    Backpack is the ultimate salvation in inventory management. Your standard minecraft inventory has 36 slots in it, just enough to be handy, but terrible for long journeys or mining expeditions to the other side of the map. Backpack nonatuples your existing inventory space. (For those of you not familiar with latin, that's 9x the space).
    How is this massive inventory boost possible? The mouse wheel. (Thanks to Edward Hand for the idea!) Sneaking while Scrolling through each of the quickslots switches you to a new inventory page. This gives you freedom to scroll through NINE different pages. Scrolling without sneaking allows you to scroll through your inventory like normal.

    If you don't quite get it, I've made a short video demonstrating:
    Is there a way to change the number of pages? I only want certain users to have x amount of pages.
    Yes, see the next question down!
    Is there permission or group manager support!
    Nope! There is however a configuration file (aptly named "config.xml") that is created on the first run and allows you to customize the amount of extra inventory pages, and who gets to use them.
    Are your inventories saved between logins and server restarts?
    Yes. Backpack saves the inventories in the same file notch does, in the "player".dat file.
    Updating all those files must be slow/I heard that I/O operations are slow.
    They are. Backpack is multithreaded, so if you have more than 1 core, you won't notice any lag.
    This mod doesn't have anything to do with Minecarts, why the Minecart Mania dependency?
    Minecart Mania offers a useful interface for a lot of things I needed in writing Backpack, and 70% of the code is actually in MM. If you really hate Minecart Mania, you can just install core, and disable all of the features from it's configuration file.

    Works fine for me. Only multiplies if i pick up more than a stack of an item.
    Have you set it to not stack over 64?
  3. Offline


    This is because is sporadically up and down. Try launching your server in offline mode if that is an option.

    Updated to v0.16. Hopefully that fixes all the issues. Please report back, MMZ_Timelord.
  5. Now it works fine for me, thank you Afforess.

    The fix seems to solve the duplication, but I'm still getting items that stack over 64. Also, items picked up are not moving to the extra backpacks unless I switch to the backpack first.

    Btw, I find it extremely impressive how fast the turnaround on the fixes have been. Really shows your effort.

    first the plugin idea FANTASTIC i know me and my players will love you for it

    second xml instead of yml :) :) :) :) :) THANK YOU!!!!!

    Thanks for the information. As I'm just now getting the restore done. I'll simply rename the directories and try the original server that I thought was corrupted. I had never seen that particular error when was unavailable before.

    Glad you like it. XML >>>> YML. No whitespace issues, and easy to read and understand. And built in Java parsing.

    Hm. Items on the ground should still get picked up when your open inventory page is full. As for the overflow on stacks - not sure why that's happening either. More debugging..

    Cheese. Sounds good.

    Awesome idea but forcing people to install MinecartMania and decfonfigure it just for this is just a horrible disservice to eveyone.
  12. Offline



    I have observed that Backpack is still wanting to stack some things in over 64. Cart Tracks are the primary culprit.

    EDIT: Easy test:

    Open your inventory and drop more than 64 of one item that normally stacks.
    Close your inventory.
    Walk forward and to pick up the drops.
    Open your inventory and observe the over 64 stack in the inventory slot.

    (end EDIT)


    That is very narrow minded of you to say. Afforess is simply reusing code... over 70% of which is already in Minecart Mania! Now what could possibly be a good reason to reinvent the same wheel?

    Configuring Minecart Mania! to NOT function is pretty easy. Maybe Afforess could simply put up a MinecartManiaCoreSettings.txt file that is already pre-configured only for use with Backpack.

    That IMHO would be an easier solution that trying to convince him to rewrite the core JUST for Backpack.

    a cool featur you could ad is that it is an item, you make it and you put it in the body armor thingy and you can put it over armor then this works

    No offense, but I explained my reasoning in the OP. Everything in MM can be disabled. If it bothers you that much, then this plugin is not for you.

    I did that with dirt and tracks, and it split into the correct stacks ... Is there any other conditions that must be present?

    Edit: NVM, got it to happen.

    Version 0.17 is up, fixing item duping for real! Thanks to TimeLord to helping me reproduce and track down the bug.

    Might want to do some drop and pickup experiments... seems that items can get lost during pickup. :(

    Example... I took a stack of 64 Cart Tracks and dropped them. Then took half a stack of 64 (32) and dropped them. Closed my inventory, switched to an empty 'page' of inventory and walked forward to pick up the 96 Cart Tracks. I got only 64 into the empty 'page' and the other 32 have magically disappeared.

    EDIT: Maybe this was left over 'garbage' data in my inventory... I can't duplicate it again. Nevermind.

    I'll delete the data folder for my user and start fresh after I empty it.

    Really? I just dropped 100 tracks on the ground (2 stacks, 64 and 36) and switched to an empty page and they picked up fine.

    Put all your stuff in a chest, and delete the "data" folder from Backpack. Then turn off the server, and reboot. It should clear any garbage.

    Yeah, It would appear it was latent data from when Backpack was goofing up. I can't get it to duplicate with fresh stacks from my storage chests. No worries... :D

    Sweet. Bug-free. What I like to hear.

    Anyone know why I get this error that disables me and my players from using backpack?

    I think using DeathChest and this plugin gives errors

    Does that still happen when DeathChest is removed? If not, you need to talk to the DeathChest author, not me. ;)

    Looks like we still have stacks that go above 64 during collection. Although if you move them, they properly separate.

    Players on my server have noticed and I started watching. While I was mining, I had a stack of 80, 67 and 73 cobblestone. As soon as I moved the stacks in inventory, they split properly.

    Looks like that gremlin is not completely gone... but at least he's not doing damage. :D

    I'm ready to sacrifice kittens to the demon gods to fix it. Any reliable way to reproduce it? I can't reproduce it by filling my inventory with stackable (dirt) and mining more.
  25. Offline


    So it seems that I am still duplicating after all, as well as having stacks above 64. The duplication occurs when I have a single block of something. I pick it up, and "underneath" the single block was a stack of 64. I place the single block down, and I can repeat this process.

    Could you explain this in a bit more detail?

    So apparently my users feel like having 9 toolbars is a hassle, could you add an option to make it persistent?

    I'm not sure what you mean. It is persistent, it only changes when you sneak.

    I have tried to get more than 64 in a stack but just cant do it
    but i have been able to pick up items even though there is no room anywhere.

    inv full of dirt(all 324 spots 64 in each), drop a stack of dirt on the ground
    get a stack of iron, toss it on the ground
    grab 32 dirt from a stack in your inv and fill in the open inv places
    you can now only pick up dirt
    walk over to the dirt and iron on the ground, you will pick up both dirt and the iron
    but the iron will be gone.

    im not not using any chest mods

    The iron should be in a different inventory page. One with free space available.

    Loose Nut

    no space anywhere (on purpose) all 9 pages full of dirt, 64 in each stack.

    i will toss out all the dirt stacks, empty my inv to see if the iron pops up somewhere
    will be a minute, its alot of dirt

    nope, no iron in inventory
