MinecraftPhi-modules VS String-Parser

Just look at the /item and item modifier wiki pages; for the loot table method, inspect https://github.com/MinecraftPhi/MinecraftPhi-modules

To add: There already a bunch of scattered datapacks that try to provide some functionality in a sort of library-way. Some are not updated anymore, some are. The ones that I know of that come to mind would be AESTD, MinecraftPhi or this much more specialised string parser.

You need to add a data pack with this loot table.

There's a MinecraftPhi module specifically for this usage, you can see more info in its github wiki page.

3: You can find the loot table here: https://github.com/MinecraftPhi/MinecraftPhi-modules/blob/master/phi.modifyinv/src/datapack/data/minecraft/loot_tables/blocks/yellow_shulker_box.json

The problem is, we can't summon the arrow directly in the block, we need to summon the arrow slightly above the block and let it fall into the block in order for the tag to be set. This means, we have to clone the block to a utility location to summon the arrow at. I'm using (-30000000, 0, 1604) to work well with MinecraftPhi-modules, so we don't need to /forceload more chunks than necessary. A second problem is that we have to wait one tick before we extract the data because the arrow needs one tick to land on the block.

using a custom loot table - When the player catches the enderpearl, store its Owner tag into a custom tag on an enderpearl item that is in a *yellow* shulker box inside a forceloaded chunk. (command below assumes enderpearl is in the first slot of box) data modify block Items{Slot:0b}.tag.CustomOwnerTag set from entity Owner then, use /loot to give the player the enderpearl that is stored in that shulkerbox (the enderpearl must be the ONLY item) loot give mine air{drop_contents:1b}

For making the compass tracker work in general, you'll need to use the shulker box loot method that overwrites the yellow shulker box's loot table in a non-obtrusive way, meaning you can still use it in survival gameplay. I recommend using the phi.modifyinv minecraftphi module for this, though it needs the phi.core module (both is in the same linked github repository), you can visit its github wiki for more information

Currently, one of the things I’m using the suso.str is to get the translated (localised) names of items from an item frame. This is done partially with command blocks and partially with datapacks for reasons I’ll try to explain below:

In Java you can use this datapack to get the current time out of a player head and set the difficulty accordingly.

reading out strings, cutting them apart and analyzing them? while technically possible, it's horribly laggy resource intensive. Also not really inteded, (ab)using some bugs and such.

The community coined term for this is "string parsing" and the most up-to-date explanation is probably inside this repository: https://github.com/5uso/String-Parser you can use this technology to either parse the output string of a commandblock (which includes the current server timestamp) or to dissect a player head's texture, which is encoded in base64 and includes a unix timestamp as to when it was requested from the skin server.
