Update to 1.21.110, improve touch UI#299
Conversation
Vanilla resources are already cached and this just takes up lots of memory. Even when I add full resource pack support I think the memory impact outweights the performance benefits.
Inspired by PurpleRain-PR/Rainbow-Editor - thanks @PurpleRain-PR. Note that unlike Rainbow-Editor, it can only export the whole scene, not individual blocks. Also flip the UVs manually rather than setting flipY on the texture - GLTFExporter doesn't recognise flipY.
esbuild can append file hashes to file names, preventing browsers from serving outdated scripts when HoloPrint updates. Fixes #298
Caches will now look at older versions if they can and automatically delete unused entries. This is a significant change and I haven't fully tested everything if anything's broken yet.
FINALLY they're adding in these missing stuff! Much more intuitive...
EntityGeoMaker is still in early days (can't handle nested rotations) but it works for copper golem statues so I'm happy.
Because it needs to load the geometry file, many things have been made async.
Also changed blockShapes.json #tex system to use <> instead of {} (looks more like templates) and improve types a bit.
Also make methods I made static last commit non-static again.
For blocks such as beds, chests and pistons, many variants use the exact same textures but in a different image file or position. HoloPrint now compares image fragments pixel-by-pixel and ignores ones that are duplicates of others. They are hashed first so the pixel-by-pixel comparisons are rare.
📝 WalkthroughWalkthroughAdds a versioned lazy caching fetchers module; removes bespoke caching from ResourcePackStack and utils; introduces EntityGeoMaker and async-aware BlockGeoMaker; stages builds via a temp workspace with hashed outputs; adds GLB export and texture-atlas deduplication; updates schemas, types, data, imports, and many public signatures.

122-122: Same regex issue with negated empty character class.This line has the same
[^]pattern issue as line 36.Apply the same fix:
-code = code.replaceAll(/<script type="(importmap|application\/ld\+json)">([^]+?)<\/script>/g, (_, scriptType, json) => `<script type="${scriptType}">${processJSON(json).code}</script>`); +code = code.replaceAll(/<script type="(importmap|application\/ld\+json)">([\s\S]+?)<\/script>/g, (_, scriptType, json) => `<script type="${scriptType}">${processJSON(json).code}</script>`);
171-171: Another instance of the negated empty character class pattern.Line 171 also uses
[^]in the template literal regex.Update to use standard pattern:
-code = await replaceAllAsync(code, /html`([^]+?)`/g, async (_, html) => "`" + (await processHTML(html, filename)).code + "`"); +code = await replaceAllAsync(code, /html`([\s\S]+?)`/g, async (_, html) => "`" + (await processHTML(html, filename)).code + "`");
🧹 Nitpick comments (12)
src/data/blockStateDefinitions.json (1)
34-34: Fix the trailing comma.The trailing comma after the array is unnecessary and makes the JSON less clean.
Apply this diff to remove the trailing comma:
- "brushed_progress": [0, 1, 2, 3], // suspicious sand/gravel + "brushed_progress": [0, 1, 2, 3] // suspicious sand/gravelsrc/EntityGeoMaker.js (1)
38-43: Consider extracting inflate handling to improve readability.The inflate calculation logic could be extracted to a helper method for better maintainability.
Consider extracting the inflate logic:
+/** + * Applies inflate to cube position and size + * @param {Data.Cube} cube + * @param {number} inflate + */ +#applyInflate(cube, inflate) { + let inflate3 = tuple([inflate, inflate, inflate]); + cube["pos"] = subVec3(cube["pos"], inflate3); + cube["size"] = addVec3(cube["size"], mulVec3(inflate3, 2)); +} if("inflate" in geoCube) { - let { inflate } = geoCube; - let inflate3 = tuple([inflate, inflate, inflate]); - cube["pos"] = subVec3(cube["pos"], inflate3); - cube["size"] = addVec3(cube["size"], mulVec3(inflate3, 2)); + this.#applyInflate(cube, geoCube.inflate); }src/TextureAtlas.js (1)
489-502: Potential performance issue with nested loops for large textures.The pixel hashing function iterates over every pixel channel individually, which could be slow for large texture regions. Consider processing pixels in chunks.
For better performance on large textures, consider processing pixels in larger chunks:
#hashPixels(imageData, startX, startY, w, h) { let hash = 2166136261; + const data = imageData.data; + const width = imageData.width; for(let y = startY; y < startY + h; y++) { + let rowStart = (y * width + startX) * 4; + let rowEnd = rowStart + w * 4; for(let x = startX; x < startX + w; x++) { let startI = (y * imageData.width + x) * 4; - for(let i = startI; i < startI + 4; i++) { - hash ^= imageData.data[i]; - hash *= 16777619; - hash >>>= 0; - } + // Process RGBA as a single unit + hash ^= data[startI]; + hash *= 16777619; + hash ^= data[startI + 1]; + hash *= 16777619; + hash ^= data[startI + 2]; + hash *= 16777619; + hash ^= data[startI + 3]; + hash *= 16777619; + hash >>>= 0; } } return hash; }src/PreviewRenderer.js (1)
1-1: Missing import forassertAsusage.The
assertAsfunction is imported but appears to be used only for TypeScript type assertions (Line 285). This seems redundant in a JavaScript file.Consider removing the TypeScript-style assertion if not needed:
-import { abs, assertAs, AsyncFactory, cosDeg, distanceSquared, downloadFile, JSONSet, max, min, pi, round, sinDeg, subVec2, tanDeg, toImageData, tuple } from "./utils.js"; +import { abs, AsyncFactory, cosDeg, distanceSquared, downloadFile, JSONSet, max, min, pi, round, sinDeg, subVec2, tanDeg, toImageData, tuple } from "./utils.js";-TS: assertAs(glbData, ArrayBuffer); +// glbData is already an ArrayBuffer when binary: truesrc/entityScripts.molang.js (1)
3-3: Consider keeping ACTIONS as a named export for better tree-shaking.Making
ACTIONSprivate and only accessible through default export prevents tree-shaking optimizations. If other modules only needACTIONS, they'll import the entire module.Consider maintaining both named and default exports:
-const ACTIONS = createNumericEnum([...]); +export const ACTIONS = createNumericEnum([...]); export default { ACTIONS, armorStandInitialization, // ... rest };src/fetchers.js (2)
90-96: Consider exponential backoff instead of fixed delay.The retry mechanism uses a fixed 1-second delay, which might not be optimal for rate limiting scenarios.
res = await retrieve(fullUrl); let fetchAttempsLeft = 5; -const fetchRetryTimeout = 1000; +let fetchRetryTimeout = 1000; while(BAD_STATUS_CODES.includes(res.status) && fetchAttempsLeft--) { console.debug(`Encountered bad HTTP status ${res.status} from ${fullUrl}, trying again in ${fetchRetryTimeout}ms`); await sleep(fetchRetryTimeout); + fetchRetryTimeout = Math.min(fetchRetryTimeout * 2, 10000); // Exponential backoff with max 10s res = await retrieve(fullUrl); }
112-114: Simplify version sorting logic.The sorting function creates unnecessary intermediate arrays and could be more readable.
function sortVersions(versions) { let versionsAndParsed = versions.map(v => [v, Array.from(v.matchAll(/\d+/g)).map(m => +m[0])]); - versionsAndParsed.sort(([, a], [, b]) => Array(max(a.length, b.length)).fill().map((_, i) => (a[i] ?? 0) - (b[i] ?? 0)).find(d => d) || 0); + versionsAndParsed.sort(([, a], [, b]) => { + const maxLen = max(a.length, b.length); + for(let i = 0; i < maxLen; i++) { + const diff = (a[i] ?? 0) - (b[i] ?? 0); + if(diff !== 0) return diff; + } + return 0; + }); return versionsAndParsed.map(([ver]) => ver); }src/ResourcePackStack.js (1)
34-46: Consider caching merged JSON responses.The current implementation merges JSON files on every request, which could be inefficient for frequently accessed resources.
Would you like me to implement a simple in-memory cache for merged JSON responses to improve performance?
src/BlockGeoMaker.js (1)
498-509: Consider using Proxy for cleaner property access.The current implementation using
Object.definePropertiesworks but could be simplified.#addEasyPropertyAccessors(cube) { - Object.defineProperties(cube, Object.fromEntries(["x", "y", "z", "w", "h", "d"].map((prop, i) => [prop, { - get() { - return (i < 3? this["pos"] : this["size"])[i % 3]; - }, - set(value) { - (i < 3? this["pos"] : this["size"])[i % 3] = value; - } - }]))); - // @ts-expect-error - return cube; + return new Proxy(cube, { + get(target, prop) { + const propMap = { x: 0, y: 1, z: 2, w: 3, h: 4, d: 5 }; + if (prop in propMap) { + const index = propMap[prop]; + return (index < 3 ? target.pos : target.size)[index % 3]; + } + return target[prop]; + }, + set(target, prop, value) { + const propMap = { x: 0, y: 1, z: 2, w: 3, h: 4, d: 5 }; + if (prop in propMap) { + const index = propMap[prop]; + (index < 3 ? target.pos : target.size)[index % 3] = value; + return true; + } + target[prop] = value; + return true; + } + }); }src/HoloPrint.js (3)
150-153: Harden item_tags.json fetch against failures.If the fetch fails, pack generation for customized controls could abort. Consider a tolerant fallback to keep building.
- itemTagsPromise = fetchers.bedrockData("item_tags.json").then(res => res.json()); + itemTagsPromise = fetchers.bedrockData("item_tags.json") + .then(res => res.json()) + .catch(() => ({}));
1526-1538: Ensure integer sizes for generated overlay textures.
safeSizecan become non‑integer when scaling, leading to decimal file names and potential atlas issues. Round once and reuse.- let safeSize = lcm((await paddedTexturePromise).width, itemTextureSize) * config.CONTROL_ITEM_TEXTURE_SCALE; // ... - controlItemTextureSizes.add(safeSize); + let safeSize = lcm((await paddedTexturePromise).width, itemTextureSize) * config.CONTROL_ITEM_TEXTURE_SCALE; // ... + let safeSizeInt = Math.max(1, Math.round(safeSize)); + controlItemTextureSizes.add(safeSizeInt); - (usingTerrainAtlas? terrainTexture : itemTexture)["texture_data"][itemName] = { - "textures": [originalTexturePath, `${controlTexturePath.slice(0, -4)}_${safeSize}`], + (usingTerrainAtlas? terrainTexture : itemTexture)["texture_data"][itemName] = { + "textures": [originalTexturePath, `${controlTexturePath.slice(0, -4)}_${safeSizeInt}`], "additive": true // texture compositing means resource packs that change the item textures will still work }; @@ - await Promise.all(Array.from(controlItemTextureSizes).map(async size => { - let resizedImagePath = `${controlTexturePath.slice(0, -4)}_${size}.png`; - let resizedTextureBlob = await resizeImageToBlob(await paddedTexturePromise, size); + await Promise.all(Array.from(controlItemTextureSizes).map(async sizeInt => { + let resizedImagePath = `${controlTexturePath.slice(0, -4)}_${sizeInt}.png`; + let resizedTextureBlob = await resizeImageToBlob(await paddedTexturePromise, sizeInt); controlItemTextures.push([resizedImagePath, resizedTextureBlob]); }));
2052-2053: Mark pixelsHash optional to match intent.Docstring says “optional” in PR notes, but JSDoc marks it required. Make it optional to avoid misleading consumers.
- * @property {number} pixelsHash FNV-1a hash of all pixels in this fragment + * @property {number} [pixelsHash] FNV-1a hash of all pixels in this fragment

Learning: In the SuperLlama88888/holoprint repository, placeholder strings like "this gets put in by the JS" in JSON UI files are replaced by JavaScript during the pack generation/build process, before Minecraft loads the files. The replacement happens at build-time, not runtime.

Learning: In src/data/blockShapes.json, the explicit suffix mappings for various sign types (like "spruce_wall_sign": "wall_sign_suffix") are intentionally kept to preserve Minecraft's inconsistent behavior, rather than letting regex patterns normalize them to prefix-based shapes. This inconsistency should not be "fixed" as it's meant to match how Minecraft itself handles these blocks.

Learning: In blockShapeGeos.json geometry definitions, zero-height faces at different Y coordinates (like y=4 and y=3.125) do not overlap and do not cause Z-fighting. Be more careful when analyzing 3D positioning before claiming geometry issues - verify that faces actually occupy the same coordinates before suggesting overlapping face problems.

1-1: LGTM! Cleaner pattern for ignoring node_modules.The pattern
**/node_modulescorrectly ignores all node_modules directories throughout the repository hierarchy, which is more maintainable than listing specific paths.src/translations/zh_CN.json (1)
54-54: Translation key matches English version correctly.The GLB export translation key is consistent with the English version and follows the established pattern.

10-12: Good practice extracting directory names as constants.Making
srcDiranddistDirconfigurable constants improves maintainability.
21-34: Staging directory approach improves build isolation.The new workflow that creates a temp directory for processing before copying to dist is a solid improvement - it prevents partial builds from corrupting the output directory if the build fails.
49-51: Good addition for Molang file handling.Treating
.molang.jsfiles as assets that should be copied without processing is appropriate for domain-specific language files.
59-75: Clever approach to update script import paths after hashing.The logic correctly maps old entry points to their hashed output filenames and updates all HTML references. The word boundary assertions in the regex pattern help prevent false matches.
36-36: Regex pattern contains problematic negated empty character class.The regex
/([^]+?)/contains[^]which is a negated empty character class that matches any character including newlines. While this works in JavaScript, it's non-standard and can cause confusion or compatibility issues.Use the standard multiline dot pattern instead:
-let importMapJSON = fs.readFileSync(`${distDir}/index.html`, "utf-8").match(/<script type="importmap">([^]+?)<\/script>/)[1]; +let importMapJSON = fs.readFileSync(`${distDir}/index.html`, "utf-8").match(/<script type="importmap">([\s\S]+?)<\/script>/)[1];Or with the dotAll flag:
-let importMapJSON = fs.readFileSync(`${distDir}/index.html`, "utf-8").match(/<script type="importmap">([^]+?)<\/script>/)[1]; +let importMapJSON = fs.readFileSync(`${distDir}/index.html`, "utf-8").match(/<script type="importmap">(.+?)<\/script>/s)[1];⛔ Skipped due to learnings

32-41: Pattern additions look correct; regexes are precise.Lantern family, lightning rod, chain, bars, and copper golem statue variants read well and won’t over‑match.
Please confirm these new patterns don’t shadow any existing per‑block overrides unintentionally (e.g., via your pattern resolution order).
60-71: Chest family updated to angle‑bracket texture spec.Looks consistent with the new schema.
Double‑check that all referenced textures exist in 1.21.110 vanilla RP (e.g.,
textures/entity/chest/copper_defaultand variants).
78-80: Piston arm texture paths: verify casing and location.
textures/entity/pistonarm/pistonArm(Sticky)may be case‑sensitive on some tooling.Can you confirm these exact texture paths exist in the vanilla assets you target?
85-85: Shulker “silver” quirk handled.Correctly maps
light_gray_shulker_boxtoshulker_silver.
95-103: Sign mappings: prefix form plus explicit suffix entries retained.Good: honors the known Mojang inconsistencies (as per prior decision).
122-123: Confirm copper_torch availability.If
copper_torchisn’t a vanilla block in 1.21.110, this entry is harmless but unnecessary.Is
copper_torchpresent in your loadedmojang-blocks.jsonmetadata?
230-236: Head/skull texture spec migration looks consistent.Paths align with entity skull textures and the player head fallback is reasonable.
259-262: New mappings (wildflowers → pink_petals, dried_ghast) look fine.No schema conflicts apparent.

In src/ResourcePackStack.js around lines 36 to 42, add explicit error handling
for jsonc() calls so JSON parse rejections are not left unhandled: wrap the call
to jsonc(vanillaRes.clone()) in a try/catch and surface a clear error (or
rethrow) if the vanilla JSON cannot be parsed; for the resourcePackJsons
Promise.all, instead of letting Promise.all reject, map each file to an
individual try/catch (or Promise that resolves to {ok:false,err} /
{ok:true,value}) so you can log parse errors with context (resourcePath and pack
id) and skip malformed pack files while continuing processing, then proceed with
only successfully parsed JSONs; ensure logs include enough context and fail fast
only for vanilla file parse errors.

src/data/schemas/blockShapes.schema.json (1)
16-25: No schema change required for current data — extract a shared TexturedShapeString if you want future-proofing.Scan of src/data/blockShapes.json shows all textured entries use only letters/digits/underscore/slash (e.g. chest<textures/entity/chest/normal>); no <> or characters outside [A-Za-z0-9_/] were found, so ^\w+<[\w/]*>$ accepts current values.
- If you expect namespaces (minecraft:...), dashes or dots in future texture names, expand the charset (example: ^\w+<(?:(?:[A-Za-z0-9_\-\.]+/)*[A-Za-z0-9_\-\.]+)>$).
- Optional: move the pattern into definitions (TexturedShapeString) and $ref it in both places to avoid duplication.

29-31: Default texture size to avoid undefinedSome geos omit texture dims. Safe default avoids undefined downstream.
- let textureWidth = matchingGeo["description"]["texture_width"]; - let textureHeight = matchingGeo["description"]["texture_height"]; + const desc = matchingGeo["description"] ?? {}; + const textureWidth = desc["texture_width"] ?? 64; + const textureHeight = desc["texture_height"] ?? 64;
31-33: Guard against missing/empty bonesIf bones is absent, current code will throw. Early-exit with context keeps behavior consistent with other error paths.
- let cubes = []; - matchingGeo["bones"].forEach(bone => { + let cubes = []; + const bones = Array.isArray(matchingGeo["bones"]) ? matchingGeo["bones"] : []; + if (bones.length === 0) { + console.error(`No bones found in geometry ${entityModelInfo["identifier"]} (${entityModelInfo["geo_file"]})`); + return []; + } + bones.forEach(bone => {
41-41: Confirm always-on east/west UV flipHardcoding "box_uv_flip_east_west: true" may invert textures unexpectedly depending on source "mirror" or face UVs. Confirm this is intended for entity models; otherwise, tie it to source data.
- "box_uv_flip_east_west": true, + "box_uv_flip_east_west": !!geoCube["mirror"],
53-56: Set pivot only when presentAvoids injecting undefined when a cube has rotation but no pivot.
- if("rotation" in geoCube) { - cube["rot"] = geoCube["rotation"]; - cube["pivot"] = geoCube["pivot"]; - } + if ("rotation" in geoCube) { + cube["rot"] = geoCube["rotation"]; + if ("pivot" in geoCube) { + cube["pivot"] = geoCube["pivot"]; + } + }
48-51: Inline inflate vec (no tuple dependency)Functionally equivalent and simpler.
- let { inflate } = geoCube; - let inflate3 = tuple([inflate, inflate, inflate]); + let { inflate } = geoCube; + let inflate3 = [inflate, inflate, inflate];
32-59: Follow-up: bone-level transforms are ignoredIf accuracy matters, accumulate bone pivot/rotation (and hierarchy) and apply to cubes. Current output uses only cube-level transforms; complex entities will look wrong.
Would you like a follow-up patch that composes bone transforms (pivot/rotation order, degrees-to-radians, and parent hierarchy) into cube transforms?

Learning: In src/data/blockShapes.json, the explicit suffix mappings for various sign types (like "spruce_wall_sign": "wall_sign_suffix") are intentionally kept to preserve Minecraft's inconsistent behavior, rather than letting regex patterns normalize them to prefix-based shapes. This inconsistency should not be "fixed" as it's meant to match how Minecraft itself handles these blocks.

Learning: In src/data/schemas/blockShapes.schema.json, the regex pattern `^\\w+<[\\w/]*>$` intentionally allows empty texture paths (e.g., `block_name<>`) using the `*` quantifier. This is by design and should not be "fixed" to require at least one character with `+`.

24-28: Good: defensive check for missing geometry addedThis resolves the prior runtime risk flagged earlier. Thanks for adding it.
38-38: Verify translate baselineTranslate [8, 0, 8] is typical for block-space centering; for entity-space this may need [0, 0, 0] or per-bone offsets. Confirm alignment with consumers of Data.Cube.
1-1: Do not removetupleimport — it's exported and used.
src/utils.js exportstuple(export const tuple = x => x;at src/utils.js:163) and src/EntityGeoMaker.js calls it (src/EntityGeoMaker.js:49:let inflate3 = tuple([inflate, inflate, inflate]);); removing the import will break the file.Likely an incorrect or invalid review comment.
src/data/blockShapeGeos.json (4)
5350-5362: Template for dried ghast tentacle looks sane.Box UVs and 32×32 texture size align with small segment use. No issues spotted.
5401-5496: Shelf: verify powered_shelf_type mapping order matches runtime.The four powered variants (0–3) are mapped; comments suggest center/right/left ambiguity. Please confirm against actual block states so indicators match expected positions.
5497-5529: copy_entity_model usage for copper_golem_statue: validate runtime support and asset presence.Assuming BlockGeoMaker/EntityGeoMaker support copy_entity_model and texture param injection (#tex), this is correct. Ensure the referenced geometry and textures exist in the active resource packs.
2611-2624: Rename to metal_bars — no remaining "iron_bars" references found.
Searched tracked files (and common variants); no matches for "iron_bars". Pattern mapping *_bars → metal_bars is consistent.src/data/blockShapes.json (8)
61-72: Chest mappings migrated to angle-bracket textures; copper variants included.Paths look correct and waxed variants reuse same textures. Good.
Please confirm these texture paths match Bedrock 1.21.110 pack names (copper_default/exposed/weathered/oxidized).
79-81: Piston textures switched to entity piston arm textures; validate Bedrock paths.If your fetchers point at Bedrock resources, verify:
- textures/entity/pistonarm/pistonArm(.png)
- textures/entity/pistonarm/pistonArmSticky(.png)
exist and case matches.
86-86: light_gray_shulker_box special-case is correct.Using shulker_silver texture is necessary. Nice catch.
96-105: Signs: angle-bracket base plus explicit suffix overrides retained.Matches prior decision to preserve Bedrock inconsistencies for legacy sign textures. Good.
123-123: Add copper_torch to torch family; OK.Shares torch shape; align with MCPE-180783 note. No issues.
231-236: Heads/skulls migrated to <textures/...> forms; OK.Default player head fallback to steve is fine. Ensure these texture paths exist in the pack.
260-263: wildflowers → pink_petals shape and dried_ghast mapping added.
- Mapping wildflowers to pink_petals is plausible; please confirm in-game parity.
- dried_ghast links to new geo; consistent with geos file.
32-41: Approve — patterns verifiedNo explicit "lantern"/"soul_lantern" mappings found; regex entries for lantern, chain, _bars, _shelf and copper_golem_statue variants exist in src/data/blockShapes.json and cover the intended forms. LGTM.
src/TextureAtlas.js (3)
340-342: Good: stable per-fragment region hashing added.Hashing the cropped region up-front is the right primitive for dedup.
514-527: Pixel indexing in equivalence check is correct now.The indices include loop offsets; this resolves the earlier report.
32-37: Field rename confirmed — no lingering atlasWidth/atlasHeight referencesNo matches for atlasWidth/atlasHeight; callers use textureWidth/textureHeight/textureFillEfficiency (seen in src/TextureAtlas.js, src/BlockGeoMaker.js, src/EntityGeoMaker.js, src/HoloPrint.js).

34-34: Complex filter logic should be extracted for readability.The inline filter function combines multiple conditions and file system operations, making it difficult to understand at a glance.

60-65: Extract script replacement logic for better maintainability.The inline logic for building script import replacements could be extracted to improve readability and testability.

66-86: Extract HTML processing logic into a separate function.The HTML file processing logic is complex and handles multiple responsibilities (reading, processing imports, updating import maps, writing). This makes the main build flow harder to follow.

10-12: LGTM: Clear source/dist config.Good to have centralized constants.
22-33: Make staging dir robust: avoid import.meta.dirname portability pitfall; use unique temp dir and always clean up.
- import.meta.dirname isn’t guaranteed across Node versions. Prefer fileURLToPath.
- Using a fixed "temp" risks collisions and leaves debris on errors. Use a unique tempDir and try/finally cleanup.
Apply this diff in-place:
-process.chdir(path.resolve(import.meta.dirname, "../")); -rmDir("temp"); -fs.cpSync(srcDir, "temp", { +process.chdir(rootDir); +const tempDir = `temp-${process.pid}-${Date.now()}`; +rmDir(tempDir); +fs.cpSync(srcDir, tempDir, { recursive: true }); -await processDir("temp"); +await processDir(tempDir); rmDir(distDir); -fs.cpSync("temp", distDir, { +fs.cpSync(tempDir, distDir, { recursive: true, filter: filename => !(path.extname(filename) == ".js" || (fs.statSync(filename).isDirectory() && fs.readdirSync(filename).every(file => path.extname(file) == ".js"))) });Add these helper lines outside the range:

127-137: HTML minification pipeline looks solid.Inline JSON minification before HTML minify is a good touch; named ESM import for html-minifier-next is known to work here.

45-49: Keep using loader "copy"; esbuild v0.25.4 supports it
esbuild added the “copy” loader in v0.14.44 and you’re on ^0.25.4, so it’s safe—and preserves runtime imports better than “file.”

433-436: Avoid clobbering transparency for deduped textures.When a fragment is deduplicated we zero out its
w/h, so#getImageFragmentTransparenciesreturnsNaN(division by zero). Because Line 415 reuses the same UV object for the duplicate, assigning thatNaNhere overwrites the canonical fragment’s transparency too. Packs with repeated textures will therefore end up withNaNtransparency. Guard the assignment for indices recorded inidenticalFragmentIndices.- transparencies.forEach((transparency, i) => { - imageUvs[i]["transparency"] = transparency; - }); + transparencies.forEach((transparency, i) => { + if(!identicalFragmentIndices.has(i)) { + imageUvs[i]["transparency"] = transparency; + } + });

9-11: Imports refactor to fetchers + EntityGeoMaker looks solidShifts to centralized fetchers and adds EntityGeoMaker cleanly; no issues spotted with usage downstream.
Also applies to: 15-16
61-61: Default ResourcePackStack in makePack is a good simplificationThe new default avoids extra boilerplate and aligns with the new ResourcePackStack behavior.
171-173: Updated call to retextureControlItems matches new signatureParameter ordering (including resourcePackStack) matches the updated function. Looks correct.
192-196: EntityGeoMaker integration and async BlockGeoMaker pipeline LGTMInstantiating EntityGeoMaker and awaiting makePolyMeshTemplates aligns with the new async flow.
216-217: Atlas dimensions wired into geometry descriptionUsing textureAtlas.textureWidth/textureHeight is correct and keeps geo metadata in sync with the built atlas.
838-841: Bedrock metadata now fetched via fetchers.vanillaDataConsistent with the new data-loading layer; no issues noted.
881-881: BlockUpdater instantiationNo issues found; works with the refactored fetchers-based schema loading in BlockUpdater.
1410-1410: retextureControlItems: signature and legacy mapping fetch updated
- Adds resourcePackStack param and uses fetchers.bedrockData for legacy mappings; both changes look correct.
Also applies to: 1459-1471
Thank you @Hellothere1234627284yehnsndnsnwnd for suggesting these UI changes! The touch controls are now available via buttons at the top, rather than on the side, reducing the possibility that they would overlap the Minecraft touch controls. This took super long to figure out..............

No internal callers use the legacy(structureFiles, config, previewCont, previewLoadedCallback)order, but sincemakePackis a public API you must preserve back-compat.

Avoid double-applying $holoprint:material_list_offset
material_list_wrapper now carries the same offset as the root material_list panel, but the imported template (see holoprint_material_list.json, Line 8) already applies $holoprint:material_list_offset. With both offsets active, the list is pushed down an extra 23px, and the additional padding makes the layout sit noticeably lower than intended even when the menu is collapsed. Please drop the wrapper offset (or the inner one) so the offset is applied only once.

[error] 72-72: Expected a property but instead found '// the material list needs to move down when the menu is visible. these padding elements are visible depending on which bits of the menu are showing. because they're all in a stack_panel, when they're visible, they push the material list lower down.'.
Expected a property here.

In src/packTemplate/ui/holoprint_touch_buttons.json around lines 64 to 121, the
material_list_wrapper is applying $holoprint:material_list_offset while the
imported holoprint_material_list template already applies that same offset,
causing a double 23px shift; remove the duplicate offset by deleting the
"offset": "$holoprint:material_list_offset" entry from the material_list_wrapper
(or alternatively remove the offset from the inner imported material_list) so
the offset is applied only once.

I already told you, don't say ANYTHING about ANYTHING in the packTemplate/ui folder.
