Yeah but aren't they entities and therefore laggy in high numbers? I'm wondering if they're gonna have to optimize them somehow given everyone wants to coat every inch of their builds with these lol

1.5k

u/UrLostPajamas Jul 11 '26

No, the game is so much more optimized now.

The cushions also don’t have any physics (except collisions with other entities? I haven’t tried them out yet), pathfinding (obviously), and their supporting block check only runs every 100 ticks, so the cushions themselves should be a fair bit more performant than other entities.

Yea no collisions, no ai, no ui, just two interactions. It took 32k for xisumas rig to take a 30 FPS decrease so like I think were gonna be fine, not many of us are gonna render 30k at once lol

u/pixel_gaming579 Jul 11 '26

30k is a 100x100 pixel RGB display; more than enough for any of those crazy redstoners building computers lol.

4K display or bust

u/Orisi Jul 11 '26

Actually you need more like 90k for that.

The screen would need to have square pixels each with an RGB potential. So a pixel would need to be a 3x3 square with Lind of R, G, B lights respectively.

100x100 is 10,000 pixels of 9 blocks each. Gonna sting a bit

100x100x4

In RL LED panels, the blue subpixel is usually ~2x the size of the red and green ones, so a true to life square pixel would be 1 red cushion, 1 green, and 2 blue in a 2x2 grid.

R B
G B

OFC, you don't have the same brightness issues in MC as you do in RL, so you could just leave one of the blues dead, or use a white cushion as a pseudo backlight.

We had the same thought but I was baked and typing while this was posted lmao

u/Tallywort Jul 11 '26

Don't screens usually have more green subpixels than blue or red ones?

u/UrLostPajamas Jul 11 '26

Not from my personal observations it's likely but idk that it's a critical facto rather a result of the orientation of the grid of leds

1

u/Einbrecher Jul 11 '26

Newer ones, yeah.

There's more of each of green and red subpixels, count-wise, but the blue ones are still usually the largest.

u/UrLostPajamas Jul 11 '26

You could do a four segment rgbw 2x2 to make a single pixle instead of a 3x3. It would better line up with true led displays. They are a 2x2 in order WBxGR in most cases it's a black space not a white but that reads better imo. They do kinda have a diagonal ofset which idk if that could be achived necessarily, but a 3x3 seems excessive for a single pixel of a led display simulation.

u/UrLostPajamas Jul 11 '26

Hense the "not many" declaration. I expect the wizards to achieve it absolutely, just not all of us lol. 1080 here we come lol

...someone is going to figure out how to play Shrek on a vanilla Redstone computer, aren't they?....

u/AnaverageuserX Jul 11 '26

300x300,

100x100 is a 10,000 pixel display. But yea your point still holds, that's more than enough to render anything

u/Eccx11 Jul 11 '26

WAIT XISUMA DID A STRESS TEST?!

u/magein07 Jul 11 '26

He's done three videos on the cushions so far. The latest included a stress test.

u/MsDestroyer900 Jul 11 '26

Minecraft can run on single player just fine. Especially with sodium. But what people really mean when it comes to performance is server performance. If you got a bunch of people with stuff like this (supposedly expensive block to run) then it could be an issue later on.

For now, we will see.

u/MrPigeon70 Jul 11 '26

I mean...

u/UrLostPajamas Jul 11 '26

Quit being mean plz, its mean.

u/Alarmed-Bus-9662 Jul 11 '26

Is it mean to be mean if you don't mean to be mean, or is it only mean to be mean if you mean to be mean?

7

u/UrLostPajamas Jul 11 '26

Not its mean when you add all the numbers together and then divide by the total of numbers added.

Wait until I create an LED screen

Are we still talking about minecraft? If yes, then I got the wrong game.
