So SkipTheTutorial made a video showing how you can use the 'Scale' attribute on the player to make better parkour, so I tried it. It was pretty fun, _{yet an eyesore to create}, but at some point, when my character is at a custom scale, it just went back to normal. In some cases, you'd clip through floors and walls! This was kind of annoying, and basically drove me nuts

I did this in a WorldEdit modpack, but WorldEdit doesn't affect the command, so you can't say it's invalid. I was also in 1.21.1, but no future logs show that it's been fixed, so you can't say it for that reason either.

PLEASE FIX IT!!!!!!

How to do:

1. grab a command block and pressure plate
2. place the command block, place the pressure plate on top
3. write this command: attribute @p minecraft:generic.scale base set <# that's not 1>
4. step on the pressure plate
5. move around a lot. Note that this randomly happens.
6. watch it happen

      7_(BONUS). stand next to a wall and hit the W,A,S,or D key on your keyboard, depending on where you're facing and where you are, when you resize unexpectedly, and you might clip through the wall. change the wall into a slab, and same for the floor. do the same thing and you might also clip through the floor too.

      It may take a few tries.
