"oh I'll make a video on mipmaps"

:later:

So if you export from substance and run the output through the ktx2 CLI you can then run it through kram with specific block compression settings per data type...

substance -> exr -> ktx array textures -> bevy's standard material processing -> with a basic height test to pick a material.

(this wasn't really the height-related example, this was the array textures pipeline test). First image is a merge of the other two materials.

as a result, the fight feels long and drags on, and your actions don't feel impactful. Its like running a race but not being told the race distance.

After having beat typhon at least a dozen times, including high fear runs, the lack of health bar is only an annoyance and I wish I could "turn it on"

Chris Biscardi @chrisbiscardi.bsky.social · 8d

It also removes any recognition of what kind of damage your build is doing. The numbers on screen are effectively meaningless: "you did N damage against ?? total".

Because the phases have different amounts of health, you can't use past experience to judge progress either.

Hades 2 is very good. One of the few decisions I question is the Typhon health bar not appearing.

A 4 or 5 stage fight, with no progress indicator, where you have to guess "is this a storyline, 'I must lose' kind of fight?", where the same attacks will double in damage without warning.

Bevy 0.17 porting progress of the community crates I'm maintaining and/or depending upon. Green crates are released, yellow are in progress.

`bevy_web_asset` was upstreamed into Bevy itself, so looks like I won't be porting that one :)

Scrolling UVs* whoops

Chris Biscardi @chrisbiscardi.bsky.social · 10d

Light textures are new in bevy 0.17, and using them with image handles is easy.

To drive them with a material we have to render that material to a texture and use it in both places. This enables generating textures or animating scrolling IVs, etc

Observers became Events and EntityEvents in Bevy 0.17, while 0.16's Event became Messages.

Here's how hooks and observers work in 0.17

Got hot reloading working w/ @chrisbiscardi.bsky.social 's excellent skein plugin. Wrote a small Blender plugin to attach gizmos to any Bevy component managed by skein - also picks up numeric values from components to drive gizmo dimensions + can show gizmo in Bevy space (no Y↔Z conversion) #bevy

I switched to the Avian physics engine! Its excellent documentation made this a pretty simple process.

The physics now run at a fixed rate, independent of the frame rate. This helps a lot with determinism and things keep their velocity, even if the rendering isn't fast enough.

It has been a month since Bevy's fifth birthday. We asked the community to reflect on the past year and outline their hopes and dreams for the next year.

The runbacks are long and mildly annoying... if you haven't gotten the traversal mechanics that greatly impact how you can traverse the runback.

A runback doesn't really have an objective difficulty, it changes (at minimum) based on item and movement acquisition.

Chris Biscardi @chrisbiscardi.bsky.social · 25d

video game difficulty is subjective, which makes takes on difficulty that treat it as objective somewhat uninteresting.

ex: saying silksong is "difficult" doesn't yield any interesting design points. Talking about the wide gap in fight lengths between tool use and pin-only is far more interesting.

I might remove this from the site even though its fun. The whole screen seems to flash on page transition in Windows Chrome

Chris Biscardi @chrisbiscardi.bsky.social · 25d

I'm dealing with a multi-page application here, so it can all be CSS for me, but yes that's the Routes transition=true

The Router example shows it: github.com/leptos-rs/le...

and has associated example css: github.com/leptos-rs/le...

Chris Biscardi @chrisbiscardi.bsky.social · 26d

the navigation: auto setting is *supposed* to work on push navigation events, even though its only consistent on traverse events here, so some debugging is needed
