Attention Fabric users: This is a Forge mod, it has always been and will always be. If I ever port it to Fabric, which I have no current plans to do, it will be as a fully separate project, and it will be clearly indicated.

How to Use

Craft the tape with string, paper and slime balls in any crafting grid (shapeless).

Right-click with the tape on a block with TileEntity (chests, machines, ...) to pack.

Harvest the box to carry it around, and place it in its target location.

Right-click on a packed block to unpack.

Note: Sneaking while placing the block will disable the rotation system while unboxing!

Allowing the tape to pack mob spawners

Add the mob spawner tile entity class to the whitelist section of the config file.

In 1.18+:

Use this datapack: https://www.curseforge.com/minecraft/mc-mods/packing-tape/files/4070570

In 1.14+

Navigate to your save folder, and inside serverconfigs, open the packingtape-server.toml file in your favorite text editor (Notepad++ is a good choice for Windows users).

In it, locate the whitelist line, and add the spawner within the brackets, like so:

whitelist = ["minecraft:mob_spawner"]

If you need to add more than one, you can separate them with commas, like so:

whitelist = ["minecraft:mob_spawner","minecraft:chest","someothermod:someothertile"]

In 1.12 and earlier:

Locate the config file in config/packingtape.cfg. Find the S:whitelist key, and add the TE within the angle brackets, one per line if you have multiple.
