Manually edit data files

[lenzls]

Hello,

I installed PerWorldInventory on a sever with several preexisting worlds in it. For the most part it works great, but some players have problems of a completely empty inventory, enderchest, ....

I have a backup of the plugins folder from right after I installed the plugin. If I view the backed up plugins/PerWorldInventory/data/186aa6d2-d6da-3467-84a3-97ea08aa9745/world.json file of a specific player the full inventory is there. In the current version of the file, the inventory is empty.

Then I tried to just copy the backed up version over the current one and restart the server. But to my surprise, the inventory was still empty. In fact it seems, that my changes get overriden from a magical source (player.dat or something like this?) every time.

Does the plugin not load the state of the inventory from these files? Why has my overriding no effect?:)

thanks for the help in advance.

regards

for completeness my configuration:

One issue is that your 'biomebundle' group is mis-formatted; it should have worlds: not world:, though I doubt that's the actual issue. PWI does indeed load from the .json files, and doesn't touch Minecraft's .dat's at all.

thanks for the hint! but the problem sadly persists.

Here is an extensive example what I'm doing:

again my config.yml and updated worlds.yml

steps:

1. this is the current data file of my player for my main world

2. I want to override this file with my backed up version

3. I copy the file from (2) over (1)

4. when the server is started, the data file version is still (2), which is what I want

5. when connecting with my client, the data file version is still (2), but my inventory is exactly the one from (1) -- so 2 things in my inventory and 1 in my enderchest

6. after closing my client, the data file is again this which is the version (1)

This is the server log from steps 1 to 6

Small question: should /pwi reload reload also the data files on the fly or only the *.yml ones?

thanks for the help :)

By the way: Out of curiosity I checked the current .dat file of my player from playerdata of my world.

And the inventory and enderchest state is exactly like the PWI data file version (1) from my previous post.

There has to be something wrong with my configuration.

It seems, that on startup PWI does not read the inventory from the json but rather from the dat. But in the end (after logging out) updates the json according to my changes ingame.

Do I maybe need to disable the 'vanilla inventory storage' somehow?

[EbonJaeger]

On startup PWI only loads the configuration files. Player data files aren't looked at until they are needed. You can think of it this way: The .dat files are your current inventory that the server is tracking. PWI's .json files are your inventories in gamemodes/worlds that you aren't in.

Do you have an idea how I can investigate my issue a bit further? The log says nothing and I am a bit clueless. Thanks for the help
