4:10 piglin agro works like this: the piglins (and brutes) naturally attack you. if you wear a piece of gold armor before going to the bastion, the piglins will not attack you. there is no way to stop the brutes from attacking you but you can kill them with lava and other stuff as they're useless.
I know about this. What I meant in the video was that I never learned the speedrun routes inside the bastion, and exploring it takes me way way longer than it needs to. And these routes depend on the piglin ai to move to the best spot possible for trading. I've never speedran, so I never got to learn them, although knowing them is still useful, especially in hardcore.
Thank you! I have nvidia geforce gtx 1050 & intel core i5 8300h 2.30. Not very good but its enough for my laptop to run minecraft and edit. Plus i would really prefer to get a desktop at somepoint, but my rl job revolves arount traveling a lot, and i just play minecraft in my free time, so a simple laptop does the trick for the time being.
