We do animation detection during the preload now, but this wasn't always working correctly: some movies don't actually fully mount the children onto the stage until we start playing. This caused the play/pause button to be missing on the outfit page and the item page, but the animations would still play, depending on the user's saved play/pause state in localStorage.
Not sure why movie clip building is failing! But it happened outside our try-catch, so it left us in an infinite spinner state.
The repro item is the Spring Topiary Garden Background!
I guess something got more picky about the loading sequencing: the fade in animation was happening faster than the cached image could load. Now, we explicitly wait for the image to load (even though we know it's probably cached) before fading it in.
Oops, our movie layer promises don't have a .cancel() method, so calling it crashed our error handler. Now, when there's an error loading a layer and there are HTML5 layers visible, we'll correctly show the "Could not load preview. Try again?" message.
So I broke the Download button when we switched to impress-2020.openneo.net, and I forgot to update the Amazon S3 config.
But in addition to that, I'm making some code changes here, to make downloads faster: we now use exactly the same URL and crossOrigin configuration between the <img> tag on the page, and the image that the Download button requests, which ensures that it can use the cached copy instead of loading new stuff. (There were two main cases: 1. it always loaded the PNGs instead of the SVG, which doesn't matter for quality if we're rendering a 600x600 bitmap anyway, but is good caching, and 2. send `crossOrigin` on the <img> tag, which isn't necessary there, but is necessary for Download, and having them match means we can use the cached copy.)
Previously I tried to be clever and pre-optimize by putting all the layers onto one canvas… I think this probably helped by batching their paints, but it made fades less smooth by not taking advantage of native CSS transitions, and it made us dip into JS way more often than necessary.
Here, I take the simpler approach: just layers of <img> and <canvas> tags, with each animated layer on its own canvas, and letting the browser handle transitions and compositing, and separate `setInterval` timers to manage their framerates.
I have a suspicion that batching the paints could help performance more, but honestly, maybe that batching is already happening somehow, because things look pretty great on my big-screen stress test now; and so if it _is_ relevant, I want to wait and see after testing on low-power devices.
Honestly kinda surprised this worked on the first go! I was worried something about the process would make the sorta like, instant-cache expectation not work.
Still thinking it might be considerate to like, keep a LRU cache of MovieClip options, so that we don't double-execute these scripts when adding stuff… we even re-execute the ones already applied lol 😅 and that adds lots of script tags to the body!
But yeah I'm not gonna push on it yet until I see evidence that it actually causes performance issues in practice
reflecting further on the abstraction, I'm noticing that this isn't an Easel abstraction like I envisioned early, and that we're baking some Neopets stuff into it. And I think that's the right call, esp with the tricky MovieClip stuff coming up, where I think more barriers would hurt more than they help. So, a new name!
Did it revert? Or did I just never notice that it only worked on mount, not on new loading states?
Also, fixed a bug where we were injecting the script tag way too much, and triggering loading too much that way too!
still just for static stuff, but it's good to be working!
PosePicker got a bit broken, CSS scaling doesn't work quite right anymore, we might need to just up the internal resolution or something?
Fading the whole preview to a black overlay for the loading state was feeling aggressive, especially since loading delay wasn't working correctly!
In this change, I fix loading delay, and I add a nice subtle "corner" variant for outfit preview spinners :)
Initially the spinner was only used in OutfitPreview, where the background was always pretty dark. Now that we use it in more general contexts, we need a light/dark distinction!
Also went and standardized out the `size` props
Huh, maybe this is a Firefox bug or something? but the container wasn't applying partial opacity correctly to its children, it was only doing 0 or 1, I think maybe because the children weren't static? I refactor here to make the DOM structure a bit more natural, and fade ins work again 🤷♀️
I'm not sure when this regressed, but changing the outfit was clearing out the whole preview and showing an empty loading state, instead of the intended behavior of showing a loading spinner over the old preview. This affected both the home page and the wardrobe page.
Yeah, so, huh. Fixed! I hope I didn't goof anything else with these effect trigger changes though 😅
The reason I'm doing this now is not just that it's annoying, but as a pair with the color change fix from just now, I want those color changes feeling buttery smooth!
Still just read-only stuff, but now you can look at all the different poses we have for a species/color!
Soon I'll make the pose/glitched stuff editable :3
Some sizable refactors here to add the ability to specify appearance ID as well as pose… most of the app still doesn't use it, it's mostly just lil extra logic to make it win if it's available!
(The rationale for making it an override, rather than always tracking appearance ID, is that it gets really inconvenient in practice to //wait// on looking up the appearance ID in order to start loading various queries. Species/color/pose is a more intuitive key, and works better and faster when the canonical appearance is what you want!)
Dice reported this, thank you!
My mistake here was that `loadImage` _does_ reject when the image fails to load… but it ends up throwing `undefined`, since I forgot to pass the error along from `onerror` to `reject`!
So we would cancel stuff, but then store `undefined` as our error in state, which our component interprets as no-error.
I tested this by using Firefox DevTools request blocking!
Hey wow this was not so hard, just set some global styles, removed some hardcoded colors, and walked through the remaining hardcoded colors to pick a dark mode variant :) neat!!
Using the newly extracted OutfitPreview! I'm really happy with how this turned out :3
It also makes the pageload after clicking Start super smooth, no spinner! Thanks Apollo cache!!
