Most of my demagnetizers, but not all of them, stop working the next time I enter my world after leaving it. They have to be broken and re-placed. The filters reset as well. Similar to #14 but also resets the filter, happens in 1.12.2, and occurs with the regular demagnetizer, not just the advanced one.

A bunch of errors relating to Demagnetize also appear in the log, which is most likely related.

Crash log
Debug log

Hello there.

The mod I develop, known as Enigmatic Legacy, as of update 1.6.2 respects Demagnetize and PreventRemoteMovement tag that it marks demagnetized items with.

I therefore request you to add Enigmatic Legacy to the list of mods compatible with Demagnetize.

The current event I am using to detect when an item spawns cannot see what the item is on the clientside. Therefore the item will appear to be magnetised on the clientside but will not be picked up and will teleport back when the client and server synchronise.

To fix this, I need to attempt to find a way to get this item on the clientside, for example by queueing an update a tick later, or when another event fires (find the event that is triggered when the client gets the item of the item entity?) so that the tag is applied correctly.

Relayed from: EnigmaticaModpacks/Enigmatica6#3373

When sorting using Inventory Tweaks Renewed while inside the Advanced Demagnetizer GUI, items are moved into the filter, effectively voiding them.

Inventory Tweaks Renewed has a config that allows blacklisting certain inventories for sorting, but for some reason blacklisting link.infra.demagnetize.blocks.DemagnetizerGui does not prevent me from sorting.

The method getEntityData() is undefined for the type ItemEntity

Thought I would give you a heads up on this.

Using the latest Forge: 1.14.4 - 28.0.92

I would like that the Ender-Convergence Device from the addon for Robotic Parts worked with this mod.

I saw that #2 added support for pickletweaks however this no longer seems to be the case as its magnet still grabs items and XP. Changing range or redstone has no effect. For testing purposes the thermal magnet is affected (but that magnet is subpar). I also tried placing the demagnetizer at different height levels to see if that had any impact but it did not. For verbosity I added demagnetize to skyfactory one pack. I also tried it in a separate instance with only PT and DM but still same results.

Demagnetize: 1.16.2-1.2.2
Pickletweaks: 5.2.6

If this requires a change to picketweaks itself please feel free to close this issue and I'll ask them for support.

Happy holidays.

First let me thank you for creating this mod, Secondly I'm being a pest and asking if you might update this mod.
That's all I have, thank you once again.

Hello,
I've been playing a modified version of DDnSS additional to a few others i have added Demagnetize as well.
Everything was working super smooth until i restarted my game after updating the pack today, which has updated the Forge version to forge-14.23.5.2847.
After attempting to load up my save the Internal Single-player Server crashed (crash-log attached below).

Creating a completely new world was working without any issues.
After some trial runs i found out that Demagnetize was causing the Issue, after removing the mod the save loaded without any issues.
Now, since i didn't want to play without it i attempted to save the world without Demagnetized installed and load it again installed. To remove any remains of it i was blessed with success!

So further testing was necessary to find when exactly the error would occur.
Next was restarting the whole game without any changes which also crashed the server.
So it was not that mods are being added, which i had originally suspected.

Then i remembered that i had white-list filters set in both of my Demagnetizers, so after restarting the game 3 more times to remove -> re-add without filters -> and restart again to check, my 3rd time loading the world greeted me with the same error again.

Some things i noticed when i created new instance with just bare bones setup of the modpack so i don't have to wait 5-min between each restart:

• it doesn't crash...
• it resets the Demagnetizers settings (filter and whitelist back to blacklist)
• console logs errors instead of crashing in the small version

• Errors appear on World reload not just Game restart
• This does not happen with the Advanced Demagnetizer

After restarting my main game and placing Advanced Demganetizers instead of the Base version and reloading the World worked without any problems. So i'll just be using the advanced ones for the time being :)

I hope this helps with finding the root of the problem.

mc-verison: 1.12.2
crash-log: crash-2019-11-29_19.31.44-server

demagnetize-forge-1.16.2-1.2.2

There is no crash, nor any major issue other than the inconvenience of having to pick them up/put them back down, and then deal with the inventory clutter that happened...but would be nice if it could be fixed.

It works but not always. I have the cooldown set to 2. It still will pull an item here or there, especially coming out of an item router.

I want the demagnetizer to only prevent me from picking up canola seeds, crystallized canola seeds, and empowered canola seeds from Actually Additions. I’m using an advanced demagnetizer. I’m not sure whether to put it on whitelist or blacklist (for instance, does “whitelist” mean “only stop magnetizing for the selected items” or “keep these items from being affected from the demagnetization”? I assume it’s the former), but I’ve tried both whitelist and blacklist, and I’ve configured it to only affect these three types of canola seeds, but the demagnetizer keeps any items from being magnetized in its vicinity regardless.

• Modpack: Enigmatica 2 (version 1.63a)
• Minecraft: 1.12.2 (duh)
• Forge: 14.23.5.2781
• Demagnetize: 1.0.1 (latest)

The vacuum chest from Ender IO sucks items in and then puts them in its inventory. The demagnetizers from Demagnetize cause this Ender IO block to stop pulling items towards it and into its inventory. This ruins the canola setup that I was going for and forces me to use the Solegnolia from Botania instead.

Versions

• Minecraft: 1.12.2
• Forge: 14.23.5.2781
• Demagnetize: 1.0.1 (latest)
• Ender IO: 5.0.40

The Botania compatability works by imitating a Solegnolia. Ender IO and Reliquary support both the PreventRemoteMovement NBT tag and Solegnolias. Solegnolias don't have an item filter, so if both the Solegnolia check and PreventRemoteMovement are used, the item filter in my Demagnetizers is ignored.

For Ender IO and Reliquary to work as intended, the Botania compat config option must be set to false, or Botania must not be installed.

The item magnet from Mekanism's MekaSuit bypasses the demagnetizers.

This mod does not seem to work with the magnets from Quantum Flux and Pickle Tweaks. I was hoping compatibility could be added. Thanks!

Hi,

I tested your demagnetize mod with both my Gobber 2 and Ring of Attraction mods and can confirm they work as intended.

Can you add these mods to the list so others know?

Thank you.
