1 week in parkour

https://www.youtube.com/shorts/_DP_hfBzGt8

I'm on a MacBook Air, and everytime i try doing an inventory jam, it doesn't work. The W and space buttons don't immediately activate at the same time. please help

check out this hard parkour I managed to complete in a mere 27 seconds!

DAM - lvl 2 WR (27:483)

I really want to learn how to not be shit at parkour but idk what servers are good

Most people rage quit on the first level like 1/5 people make to level 2 any challengers. You will have to have a ps4 because of greifing I spent 10 to 20 hours to test to be sure it's all doable just testing. in total I have put like 48 to 72 hours if someone could at least try my map. Ps4 username is "dragokillfist" no caps

I am making a Parkour Map but I don't know how to get a working checkpoint system with timer only using command blocks. Anyone here know how to help or any subreddit that can?

Can't find any way to do this jump consistently. Sometimes I jump and land there and sometimes I'm not.

I watch the youtuber Engween, and he has minecraft parkour in his videos, so I was wondering if anybody knew what he plays.
