Datapacks (1.17)

Hey everybody!

I'm in the process of learning datapack creation, and was looking for some inspiration - I'm a big fan of reverse engineering stuff, and it's kind of hard for me to work on stuff without a set goal in mind, so please drop any cool datapack stuff (specific features), I'm in need of some inspiration!

 

I once made a simple magic system using custom advancements, where the gist was that when you kill a mob with a golden axe, you'd get its powers: for an Iron Golem, slowness and strength, for a dolphin water breathing, and no other mobs because I didn't add any. Also a kind of "alchemy", which was transmuting metal blocks into a higher tier in a crafting table using an XP bottle. Something like that might be cool to make.
Also I think I still have the datapack on my pc, I could upload it if you're interested.

Here you go

 

If you’re not familiar with these, I suggest looking into advancements, loot tables, and predicates.

advancements can also be used as event listeners, as you can have them be invisible and run a function as a reward. This function can remove the advancement, and this way it actually can be fired multiple times a tick, for example in crafting.

This actually can be used in custom crafting to replace the item crafted with a custom item with nbt.

To go even further, shaders can in theory be used to change the texture of the item displayed in the grid before it’s crafted. I haven’t tested this though.

Predicates can be used for rng, and also detect sneaking and sprinting.

loot tables can be used for item nbt modification (in a complex way involving shulker boxes) because the way the /item command actually sucks. It should have just been a /data command for items in the player’s inventory.

 

Bumping this real quick because I might want to post something later
