Fast Nether Portals
This data pack makes it so that, when going through a nether portal in survival mode, you go through (almost) instantly, just like in creative mode.
Simply add the data pack to a world and it should be good to go!
Important Note
When you first go through a nether portal (when chunks in nether are being loaded for the first time), you won't travel quite as quickly, as the chunks in the nether need to be generated. There's not anything I can really do about this. It's still faster than vanilla though. Once the chunks have been generated in the nether, you should be able to travel through the portal in under a second, depending on lag.
Uninstalling the data pack
In the event that you wish to remove the data pack from your world, run the command /function fnp:uninstall, and THEN remove the data pack.
If you don't run the command before removing the data pack, the pack's functionality won't be removed and you'll have to remove it by changing a gamerule. The function just makes it easier to uninstall.
How it works
This data pack works by changing the playersNetherPortalDefaultDelay gamerule (added in 23w42a) every time the world/server is loaded (via load.mcfunction) to a value of 1. This means that the game will only add in a 1 tick delay when going through nether portals. By default (in vanilla), this is a 80 tick (~4 second) delay.
