[torn crown]

looks like it?

[ripe abyss]

Take your time to read the massive changelog

[slate elbow]

I will continue to note the lack of stable entity.target and no one can stop me

[dense plinth]

Read between the lines!

[royal basalt]

yay

huge

wait, wasn't this going to be used for the creaking?

[copper pier]

Not rizz approved 😤

[royal basalt]

I'm going to guess you're Eddy 😂

[weary kelp]

what would that field do?

[copper pier]

Mhm

[woven stream]

Happy preview day

[weary kelp]

if anything, they're probably using event filters to replicate the behavior

[dense plinth]

I think it says something else there, does anyone else have a magnifying lens

[lilac remnant]

Skipped 1.21.40.24

[forest marsh]

"Huge" update, trust

[sudden dune]

next preview is pale garden 🙏

[mint finch]

Why?

kayla already said its about to be small

[torn crown]

next preview is gonna be peak 🙏

[mint finch]

How so?

do you expecte some new script api features?

[torn crown]

(maybe)

[forest marsh]

Well, I didn't know about it :/

[lilac remnant]

Creaking

Most likely

[weary kelp]

im hoping for pale garden since java got it

[paper grotto]

New Preview cycle

[weary kelp]

(I wanna see how data-driven the creaking is)

[mint finch]

Ya, so new script api features maybe

[real isle]

fr?

[paper grotto]

We’ll see

[weary kelp]

invisible ink??

[mint finch]

well happy preview day anyway!!!

[royal basalt]

omg, the most long awaited tag here is

[lone obsidian]

GIANT PREVIEW DYAYYAYAYYA

HUGE (but some nice stuff :3)

[weary kelp]

wondering why they even bothered making the allow_invulnerable field versioned, considering it never even made it out of preview

[devout pewter]

Unfortunately not, I think the preview might've been delayed so that they can fix that graphical issue without revealing shader source 😭
Well at least we got a 1.21.31 hotfix with exposed shaders

[weary kelp]

wait nvm, it was in the original component

[fickle torrent]

Minecraft Preview v1.21.40.25 is out now on the Microsoft Store!

[ornate crag]

Happy preview!

Should I read this changelog slowly?

[mint finch]

Its hidden

[dense plinth]

https://youtu.be/55TD_EkHtSg?feature=shared

[raven turtle]

They had to delay the preview because they needed more time to write the changelog

[tame reef]

My guess is that they will redesign the component to better match the current system so it can be used by the Creaking (and hopefully be able to be used by creators? 🙏)

[native seal]

smol :(

[real isle]

It's the same thing every preview cycle. From "we're so back" to "it's over" to "we're so back" and so on. xD

[orchid cedar]

djsnwjdjdjjs

wait is that black rendering bug fixed

i see it in deferred

was it for normal game too

if so then the update is still a decent W

ruined my prizma deferred survival run immersion

[foggy hemlock]

performances are still not good in preview

I still hope it will not be the future of bedrock's performances

[tacit berry]

I wonder whether the new cycle will come out next week or the week after…

[brazen brook]

Let's go!! Absolutely nothing interesting!

[copper pier]

That’s deliciouso right there that’s rizz approved

[inland inlet]

What is this for? And is this only available on the desktop? Because I don't see this on my screen

[wild sorrel]

Huge update!!!

[unique atlas]

wow this ones a smol boi

[balmy flower]

usually after that there's a big one

[lone obsidian]

mhhh structure blocks prolly

they are quite close

[silver furnace]

I wonder if they can fix the /reload all command being even slower then leaving and joining back manually, like its not even usable for development purposes at that point.

[ruby lion]

well it does depend on the hardware. some might be faster than manually reloading, some might be opposite.

honestly i don't see any room for some optimization since that command will also load resources when on the world screen.

[lone obsidian]

Is it really that bad?

I mean.. I haven't used it, but this seems like a giant flaw

[ripe abyss]

Over time we want to increase the number of things that can be "hot" reloaded. And we also want to improve overall resource loading speeds. So, yeah, we know this loop isn't ideal and we want to make it better.

But I also don't understand how you're seeing it being much slower...

[mint finch]

Well its so better then manual re-opening world, bc i can check the discord in the meanwhile 😅, also its faster for me like 180% so far so good 👍

[real isle]

From my own experience with it, it takes close to a minute after the world closes for it to open back up. It's faster for me to just open the world manually

[royal basalt]

Hot reloading is just a little slower for me

[ripe abyss]

That may not flush all data. Some of it stays cached. /reload guarantees that all of it is reloaded.

[real isle]

If only there was a way to see what it's doing while waiting

[dull tendon]

Idk if the size of com.mojang folder affects the reload times. I’ve been trying to figure how to reduce the game starts time without removing too many files but it’s unsuccessful

[silver furnace]

I thought it was suposed to be like that? Its supposed to be faster then leaving and joining if thats the case, maybe I need to report a bug with slow loading?

[ripe abyss]

no, not a bug. It's a pretty heavy-handed approach to flushing everything. But over time we want to add more hot-reloading things like what you can do with scripts today

[silver furnace]

Ah, okay that makes sense.

[silver furnace]

I noticed not a large one, but some performance increase when there is alot of Minecraft Marketplace cache files.

Deleting those sped it up some.

[ripe abyss]

load times increase, you mean?

[silver furnace]

I mean the speed of which it takes to load a world in general seems to be faster. When deleting those files.

But not by much.

[ripe abyss]

that's not suprising. another thing that impacts load times significantly is lots of stuff in development BP/RP folders. since (I beleive) everything in those folders is scanned on load.

[silver furnace]

Yeah, I hope in the future maybe there would be a way to manually set files and folders in them to be ignored/skipped.

Like ignoring .git folder would be amazing even if that was it.

[ripe abyss]

yeah git folders in your dev BP/RP folders will absolutely lead to slowdown.

[stuck gorge]

I kind of wonder why it's so slow too. Java takes its time loading large data packs and resource packs, but it's still faster than Bedrock.

[devout pewter]

Bedrock's behavior and resource packs are also quite a bit more complex than java's tho

[stuck gorge]

Resource packs, sure. However, datapacks are slowly getting features that require a full world reload to take effect.

[ornate crag]

I've found reload all to be just as fast or marginally slower then leaving and joining but with the benefit of I can do other things

[ornate crag]

Git in the com.mojang folder? 😭🫠
That feels like a sure fire way to be able to lose local changes if not pushed if Mc does something weird. Plus those pack files

[lilac remnant]

For me, it crashes after reaching the worlds screen so it's way slower

[final pawn]

what in the world happenned to item frames this preview

loaded into my world with 500 errors and all my items in item frames are now "gone" but the frames are indestructible

unless I break the backside

[tall fog]

Frames being indestructible happens when an item that was there doesn't exist anymore

like if the items broke

I have that happen in stable too

[final pawn]

the item does exist though

I should have copied the clipboard error

It was one of those situations where all the items "don't exist" when you load in

but then leaving and rejoining the world doesn't have any errors and the items are all back

[oak shoal]

How else can you even do it? You can't symlink it into the folder, because UWP hates symlinks for no reason. And you can't symlink the folder into a git repo elsewhere, because git hates symlinks for no reason

[weary kelp]

You have the option of using tools like regolith. Also, you can symlink in com.mojang, but you have to apply certain permissions to make it work

[cinder quarry]

Regolith mentioned

[oak shoal]

Show me the steps to put a symlink in dev behavior packs and have the game read it please

[weary kelp]

I can't give you any steps to do straight from a command prompt or anything, but I can send you some code I wrote for my launchers to do it

[oak shoal]

I know how to hotswap the entire folder, but that's too coarse to be useful

[weary kelp]

I'm not hotswapping

[oak shoal]

Sure I would be interested but only if it's for a pack folder inside the dev folder, not anything above that

[weary kelp]

here's how it was done in rust (I also have implementations in C# and go)
https://github.com/MajestikButter/mc-launcher/blob/main/src-tauri/src/model/profile.rs#L97

[weary kelp]

here's what it looks like in practice

these all link to my build folders elsewhere

[oak shoal]

Thanks! I'll try myself later

[weary kelp]

it's possible, just tedious

the most annoying part of it is that you need to apply those permissions to both the symlink and its destination, since UWP doesn't allow the game the access anything that isn't explicitly given access, though that's simpler if you allow the permissions to be recursively added/inherited

[dense plinth]

Yea I just set up a junction between dev packs and my git repo

[ornate crag]

Regolith or dash of something similar that move the rp bp into com.mojang folder. Also comes with the benefit of filters and compiler extensions to do other things at the same time

I have I think last time I checked 27gb or project repos checked out, I'd hate to see how long Mc takes to load with that.

We do have a forbidden repo from back when we did dev in com.mojang 👀🫠

[cinder quarry]

Dash...

https://tenor.com/view/clown-mcdonalds-thumbs-down-i-dont-think-so-gif-16021541

[ornate crag]

I put regolith first!

[oak shoal]

I find it hard to justify using those. Load times are bad enough without sitting through a flaky "compile" step, and you have to look through the output anyway to debug. After making the fix in the output, testing that it works, you then have to figure out how to make an equivalent fix on the input or pipeline code, compile again, and verify it still works. Not my preferred workflow

[ornate crag]

I don't think I've often needed to shift through the compiled output to debug. Just start watchmode and then if I change one file just that one file gets rebuilt.

Plus now with scripting i just have js in Minecraft folders and the ts is in dev folders so debugging there's isn't that helpful.

Either way, if you put a bunch of extraneous files in a folder it's going to slow down load times

[oak shoal]

Yes to be clear I don't do this anymore because of the horrible load times of the dev folders

[stuck gorge]

Let us be able to install Bedrock multiple times so we can have "workspaces" that aren't affected by other projects.

That's actually what I do on Java and it's really helpful.

[dense plinth]

That is what I do with a version switcher!

[keen merlin]

rip bedrock version switchers

Microsoft wiped out versions data for bedrock minecraft

[woven stream]

What?

[royal basalt]

They did?

[copper pier]

https://tenor.com/view/duck-crying-sad-duck-sad-meme-duck-gif-20933151

[woven stream]

So that means no bedrock version switcher will work now

?

[weary kelp]

I think they're talking about old version downloads

if you already had the versions installed, you can still switch to them

[woven stream]

Yea but what about ppl like me you don't have the old versions

We just can't downgrade now?

[weary kelp]

then you're out of luck, you can probably only switch between recent versions

(assuming they actually did wipe the old downloads, I haven't checked)

[woven stream]

Why Microsoft

We were promised java and bedrock parity (might be a well thought out decision so...)

[weary kelp]

parity doesn't include external things, don't see why it would

[woven stream]

I see

[keen merlin]

by parity, it means only gameplay wise by in-game features. It does not include any technical support externally

[frigid belfry]

Only old Previews I belive

@keen merlin any example of specific removed version?

Non-Preview / beta

[keen merlin]

just like you said, old versions

maybe try 1.18.20.22

[frigid belfry]

Yeah Previews is normal
Does this apply to any release versions?

[keen merlin]

maybe yes

i haven't looked into it much. @paper grotto and @cinder quarry were the witnesses of the situation
