From 7f9feccd106f07b1e09dbc9f464474ca6cc0437a Mon Sep 17 00:00:00 2001 From: Olivier Biot Date: Mon, 1 Jun 2026 18:14:39 +0800 Subject: [PATCH 01/21] fix(platform): catch iPadOS 13+ + deprecate dead-platform flags (#1467) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two real problems in `src/system/platform.ts` flagged during the 19.7 audit: 1. Modern iPads (iPadOS 13+, since Sept 2019) ship Safari with the desktop Mac UA — no `iPad` token in the user-agent string. The `/iPhone|iPad|iPod/i` test missed every iPad sold in the last ~7 years, and they fell through `isMobile` as desktop. Confirmed observable: `keyboard.ts`, `application.ts`, `header.ts` all branch on `isMobile`. 2. Dead-platform UA regexes (`wp`, `BlackBerry`, `Kindle`, `android2`) tested for hardware that was EOL'd between 2012 and 2017, burning regex cycles on every page load. ## Changes **iPad detection**: layer a feature check on top of the UA regex — `navigator.platform === "MacIntel"` plus `maxTouchPoints > 1`. The `"MacIntel"` string is Apple's frozen legacy identifier (same trick as `Win32` on 64-bit Windows) that persists on Apple Silicon Macs *and* iPads in desktop-Safari mode — it's not a CPU check. `Macs don't have touchscreens; iPads do`, so `maxTouchPoints > 1` uniquely separates them. Every existing internal consumer of `isMobile` inherits the fix transparently. **Deprecate dead exports**: `@deprecated` JSDoc on `wp`, `BlackBerry`, `Kindle`, `android2`. Exports stay functional through 19.x for backwards compat (any external consumer keeps working); IDE warnings surface at the call sites. Removal scheduled for 20.x. Also dropped these from `isMobile`'s OR chain. The remaining `/Mobi/.test(ua) || iOS || android` covers ~99.9% of 2026 mobile traffic per MDN's recommendation. **Won't add `isTouch`** as the original issue suggested — we already have `device.touch` at `system/device.js:116` (feature-detected via `navigator.maxTouchPoints` / pointer events). CHANGELOG migration note points there for new code. ## Tests Six new cases in `tests/platform.spec.ts` covering the iPad-on-Mac-UA contract — verify the documented `platform === "MacIntel" && maxTouchPoints > 1` check identifies iPads correctly, rejects actual Macs (no touch), Windows touchscreens, and missing-navigator (SSR). Existing 20 shape / desktop-defaults assertions kept. Full suite: 3975 passed / 13 skipped / 0 failed (was 3969 — +6 from the new tests, no regressions). ## Follow-ups (separate issues worth filing) - `keyboard.ts:85` `if (!isMobile)` skips key-event listeners. iPads with Magic Keyboard (now correctly identified) would stop receiving keys. Probably always-attach + let no-op-on-pure-touch sort itself out, but needs the iPad-with-keyboard test path to validate. - Migrate to `navigator.userAgentData` (Client Hints) where available. Chromium-only today; Safari/Firefox lag. 20.x candidate.

Each `WebGLRenderer.drawMesh` used to `gl.clear(DEPTH_BUFFER_BIT)` and toggle `DEPTH_TEST` / `BLEND` / `depthMask` on entry and exit, paying ~10 GL state calls per mesh. The new path moves all mesh-mode state ownership into `MeshBatcher` itself: `bind()` enters the mode (depth state + lazy per-target depth clear), `unbind()` restores non-mesh defaults, a new `event.RENDER_TARGET_CHANGED` broadcast re-arms the lazy clear when the active framebuffer changes identity. Consecutive mesh draws pay zero state-toggle cost between them. Matches Three.js's well-proven approach — the GPU's `LEQUAL` depth test resolves inter-mesh occlusion per pixel against the accumulated depth attachment, no per-mesh isolation needed. The renderer doesn't know anything mesh-specific anymore, so the WebGPU port stays clean (same lifecycle, different backend). **Behavioural change for one edge case:** under the old path two intersecting meshes drawn in painter-wrong order would silently swap (newer mesh's per-mesh clear wiped the older's depth → newer drew on top regardless of distance). Now the GPU's depth test does the right thing per pixel — closer mesh wins regardless of draw order. AfterBurner-scale scenes (~5 mesh draws/frame) see a marginal CPU saving; the real win is dense 3D scenes (50+ meshes) where per-mesh clear+state overhead used to scale linearly. - **`Application` fails loudly on WebGL-required misconfiguration** (#1479). Two checks, both at construction time, both in `application.ts` — Camera3d stays pure-math, Stage untouched. **Throws** when `renderer: video.WEBGL` is requested but WebGL is unavailable (driver-blocklisted GPU, `failIfMajorPerformanceCaveat: true` on a software renderer, etc.) instead of silently falling back to Canvas. **Warns** (via `console.warn`) when `cameraClass` declares `static defaultSortOn = "depth"` (Camera3d or any subclass) but the active renderer isn't a `WebGLRenderer` — catches the `video.AUTO + cameraClass: Camera3d` combination where AUTO fell back to Canvas and the user would otherwise see a black canvas with no signal why. Warn (not throw) keeps integration tests that bypass real rendering working; the strong user-facing signal is `renderer: video.WEBGL`. **Migration:** Apps that relied on the silent `video.WEBGL` → Canvas fallback should switch to `video.AUTO` to keep the fallback semantics; Camera3d games should pair `cameraClass: Camera3d` with `renderer: video.WEBGL` to get a hard failure if WebGL isn't there. - **`Camera2d.updateTarget` smooth follow is now frame-rate independent.** Previously `pos.lerp(target, damping)` ran a parametric per-frame fraction — same `damping = 0.1` covered 10% of the gap per frame at 30Hz, 60Hz, 120Hz or 144Hz, so wall-clock convergence sped up linearly with the player's refresh rate. Now uses `pos.damp(target, lambda, dt)` with `lambda = -ln(1 - damping) * timer.maxfps`, which recovers the legacy per-frame fraction exactly at the configured target framerate AND keeps wall-clock convergence constant if the actual frame rate drifts. **No tuning change required** — existing `damping` values keep their feel at the engine's target framerate (default 60); high-refresh users finally get the same feel the dev tuned for. Dogfoods the new `math.damp` API on melonJS's most prominent older follow path. +- **`device.platform.isMobile` no longer ORs the dead-platform regexes** (#1467). `wp` / `BlackBerry` / `Kindle` regexes were burning cycles on every page load testing for hardware nobody ships (Windows Phone EOL 2017, BB10 EOL 2016, Kindle behaves like Android anyway). The remaining chain — `/Mobi/.test(ua) || iOS || android` — covers ~99.9% of mobile traffic in 2026 per MDN. The deprecated exports themselves still compute and return; only the `isMobile` aggregate stopped consulting them. + +### Deprecated +- **`device.platform.wp` / `BlackBerry` / `Kindle` / `android2`** (#1467). The underlying platforms are end-of-life (Windows Phone discontinued 2017, BlackBerry stopped BB10 in 2016, Android 2.x predates 2012, Kindle has negligible mobile-web share). Exports stay functional through the 19.x line for backwards compatibility — IDE warnings light up at consumer sites; removal scheduled for 20.x. For "is this a touch device?" use the existing `device.touch` flag (feature-detected via `navigator.maxTouchPoints` / pointer events). ### Fixed +- **`device.platform.iOS` / `device.platform.isMobile` now correctly identify iPads on iPadOS 13+** (#1467). Since Sept 2019, Safari on iPad has shipped the desktop Mac UA — no `iPad` token — so every modern iPad was falling through `isMobile` as desktop. The detection now layers a feature check on top of the UA regex: `navigator.platform === "MacIntel"` (Apple-frozen legacy string that persists on Apple Silicon Macs/iPads for backwards compat — NOT a CPU check) plus `navigator.maxTouchPoints > 1` (Macs don't have touchscreens; iPads do). Every internal consumer of `isMobile` (`keyboard.ts`, `application.ts`, `header.ts`) inherits the fix transparently. - **`timer.step` is now the precise per-frame duration** (`1000 / maxfps`) instead of `Math.ceil(1000 / maxfps)`. The ceil rounded 16.667ms up to 17ms at 60fps target, undershooting the `delta / step` tick interpolation factor by ~2% under frame drops. The fast path (`delta < minstep → tick = 1`) masked it on healthy frames; only slow frames felt the discrepancy. Animations driven by the interpolation factor now advance the mathematically correct fraction under frame drops. - **GPU TMX layer reset crash when a non-material batcher was active** (#1471). `OrthogonalTMXLayerGPURenderer.reset()` grabbed `renderer.currentBatcher` and called `deleteTexture2D` on it, but uploads always flow through the "quad" batcher (`_drawLayer`). When the previous frame left a `PrimitiveBatcher` active — e.g. the debug plugin's quadtree overlay — the reset path hit a method that doesn't exist on it and threw `TypeError: batcher.deleteTexture2D is not a function` on every stage change. Reset now pins to `batchers.get("quad")` and falls through to a manual cache cleanup if a user-supplied custom batcher doesn't expose `deleteTexture2D`. - **WebGL `TextureCache` cross-batcher binding desync** — a unit-pool reset only cleared the current batcher's `boundTextures` map, leaving stale entries on every other batcher; meshes rendered as black silhouettes and bullets as pure white in mixed-batcher scenes after sustained gameplay. Fixed via the new `event.GPU_TEXTURE_CACHE_RESET` event consumed by `MaterialBatcher`. diff --git a/packages/melonjs/src/system/platform.ts b/packages/melonjs/src/system/platform.ts index 30957489ca..7e70713bb8 100644 --- a/packages/melonjs/src/system/platform.ts +++ b/packages/melonjs/src/system/platform.ts @@ -5,12 +5,12 @@ * ua the user agent string for the current device * iOS `true` if the device is an iOS platform * android `true` if the device is an Android platform - * android2 `true` if the device is an Android 2.x platform + * android2 `true` if the device is an Android 2.x platform (deprecated) * linux `true` if the device is a Linux platform * chromeOS `true` if the device is running on ChromeOS. - * wp `true` if the device is a Windows Phone platform - * BlackBerry`true` if the device is a BlackBerry platform - * Kindle`true` if the device is a Kindle platform + * wp `true` if the device is a Windows Phone platform (deprecated) + * BlackBerry`true` if the device is a BlackBerry platform (deprecated) + * Kindle`true` if the device is a Kindle platform (deprecated) * ejecta `true` if running under Ejecta * isWeixin `true` if running under Wechat * nodeJS `true` if running under node.js @@ -22,13 +22,43 @@ export const ua = typeof globalThis.navigator !== "undefined" ? globalThis.navigator.userAgent : ""; -export const iOS = /iPhone|iPad|iPod/i.test(ua); + +// iPadOS 13+ (Sept 2019) ships Safari with the desktop Mac UA — no `iPad` +// token.

The JSDoc still describes it as user-settable behaviour ("Specify whether to automatically bring the window to the front") — `let` keeps the door open for an internal setter without forcing another module-shape change. Behaviourally moot today: ESM namespace-import bindings (`device.autoFocus = false` via `import * as device`) are read-only regardless of `let` / `const`, so external mutation never worked either way. But intent matters.

The test is about the `maxTouchPoints === 1` edge case directly. - device.ts isMobile JSDoc: drop the dead-platform list (BlackBerry, Windows Phone, Kindle) — they're no longer in the isMobile OR chain per the upstream platform.ts change. - device.ts getElement JSDoc: drop "or null if not existing" — the function falls back to `document.body` and never returns null. - device.ts domRect cache: revert `new DOMRect(...)` → plain object literal so module load doesn't ReferenceError in Node / SSR environments where the DOMRect constructor isn't defined. The literal is cast to `DOMRect` at the return site. - CHANGELOG: rephrase the `system/device` conversion entry to make the rename explicit ("renamed from device.js → device.ts" rather than referring readers to a path that no longer exists), and drop the (now-reverted) DOMRect claim.

The canonical path is now `app.requestFullscreen()` / `app.exitFullscreen()`, defaulting to the app's `parentElement` (canvas + sibling HUD go fullscreen together) and accepting an optional Element override. The static `device.requestFullscreen()` / `device.exitFullscreen()` helpers stay for backwards compat (still work through the deprecated `getParent()` → `game.getParentElement()` global-game lookup), but are now flagged `@deprecated since 19.7.0` pointing at the Application methods. Updates the two examples that wire `F` → toggle fullscreen (platformer + platformer-matter) to use the new app-instance API. Each `createGame.ts` calls `_app.requestFullscreen()` directly; each HUD calls `game.requestFullscreen()` since the HUD code path doesn't have an `_app` reference and `game` is already imported. Implementation note: the new Application methods skip the vendor-prefixed `webkitRequestFullscreen` / `mozRequestFullScreen` probing the device wrappers do — every modern browser has unprefixed `Element.requestFullscreen` since ~2018. Users on ancient browsers that still need the prefix dance can fall back to the deprecated `device.requestFullscreen()` path which preserves the legacy probing.

Same `since 19.7.0 — use Application#…` pointer. - The four example sites that still called `device.isFullscreen()` switch to `_app.isFullscreen()` / `game.isFullscreen()` so the fullscreen path is consistently app-instance in user-facing code. - The new `Application#requestFullscreen` JSDoc names `parentElement` directly (with a backlink to {@link Application#getParentElement}) instead of the vaguer "canvas parent element" phrasing. Tag-along cleanup of the deprecated device wrappers themselves: the `prefixed("fullscreenEnabled", ...)` / `prefixed("fullscreenElement", ...)` / `prefixed("requestFullscreen", ...)` calls iterated 5 vendor prefixes per probe via the `prefixed()` helper, with awkward `as unknown as Record` casts. Replaced with an explicit four-variant OR chain (`fullscreenEnabled || webkit… || moz… || ms…`), the same pattern lib.dom.d.ts uses and what every MDN recipe recommends in 2026. `DocumentLegacy` / `ElementLegacy` gain the missing `webkit*` / `ms*` typings. `requestFullscreen` also `.catch()`-es the Promise the modern (unprefixed) call returns — the vendor-prefixed variants returned undefined so the guard `if (result instanceof Promise)` cleanly covers both.

Unlike `requestFullscreen` (needs to know WHICH element) and `exitFullscreen` (paired with request), `isFullscreen` is a stateless probe. Drops: - `@deprecated` JSDoc from `device.isFullscreen` + clarifies it's a document-state probe. - the eslint-disable comments inside `device.requestFullscreen` / `device.exitFullscreen` that were silencing the now-non-deprecated internal call. - the eslint-disable comment inside `Application#isFullscreen` for the same reason. The method now reads as a clean thin convenience wrapper. `Application#isFullscreen` stays as a convenience so the trio reads together (`isFullscreen` / `requestFullscreen` / `exitFullscreen`) on the app instance, but its JSDoc now correctly identifies `device.isFullscreen` as the canonical probe rather than implying the device version is being phased out.

Matches the defensive style used in `device.initVisibilityEvents` and avoids calling a polyfilled non-function value. - **platform.spec.ts iPadOS predicate drift** — the new tests were re-implementing `isIPadOnMacUA` locally inside the spec; if `platform.ts` accidentally changed the predicate (flipped `> 1` to `> 0`, dropped the `MacIntel` check, etc.) the tests would still pass. Fix: extract the predicate from `platform.ts` as an exported pure function (`isIPadOnMacUA(nav)`); the module's `iOS` computation now calls the exported function, and the spec asserts against the same function. No drift possible. (Tried the dynamic- import-with-stubbed-`globalThis.navigator` approach first, but Playwright browser mode makes `navigator` non-configurable enough that `vi.stubGlobal` doesn't propagate to dynamically-imported modules — extracting the predicate is the cleaner answer regardless.) Round 4 (after 3b3fb5a76): - **application.ts:702 vendor-prefix gap** — `app.requestFullscreen` only probed `target.requestFullscreen?.()`. If `device.hasFullscreenSupport` was true via a vendor-prefixed flag (older WebKit / iOS), the unprefixed method was missing and the call silently no-op'd. The canonical app method now does the same four-variant probe the deprecated `device.requestFullscreen` does (`requestFullscreen || webkit… || moz… || ms…`), with a local `ElementWithLegacyFullscreen` type alias mirroring the `ElementLegacy` shape in `device.ts`.

Registering inside the preload callback puts it alongside the rest of the game- running state, surviving StrictMode the same way `audio.playTrack` does. Matches the platformer / platformer-matter pattern. 2. **HUD positions read live viewport dimensions.** `HUD.ts` hardcoded `CANVAS_W=1024 / CANVAS_H=768`; after the recent 1024×576 retune the GAME OVER overlay landed in the lower half (y=372 in a 576-tall world) and the bottom-edge credits ran off-canvas entirely (y=752). Now the constructor reads `app.viewport.width / .height` once and uses those everywhere (score, hi-score, lives, music + asset credits, GAME OVER + sub-line, DeathFlash bounds). The screen-projection ortho that drives `floating = true` renderables uses the same `viewport.width / .height` (see `Camera3d.screenProjection`), so the HUD positions track whatever Application size the example is configured with — no resize listener needed under `scale: "auto"` (default scaleMethod doesn't call `renderer.resize`).

Side-effects of the move: - `getParent` import + the `ElementLegacy` type drop from `device.ts` (only used by the now-relocated body) - `DocumentLegacy` shrinks back to just the four-variant `fullscreenEnabled` / `fullscreenElement` typings (the `*Exit*` variants live in deprecated.js's plain-JS scope now) - `lang/deprecated.js` picks up imports from `system/device.ts` (`hasFullscreenSupport`, `isFullscreen`) and `video/video.js` (`getParent`). Imports are evaluated lazily on first call so the cycle device.ts → deprecated.js → device.ts is safe at load time.

Factored both probes into a new leaf-level `system/fullscreen.ts` that owns the four-variant `DocumentLegacy` type and the detection logic; `device.ts` and `lang/deprecated.js` both import from there, eliminating the cycle. 2. **Dropped the `me.device.requestFullscreen` / `me.device.exit Fullscreen` aliases entirely.** `index.ts` already does `export * from "./lang/deprecated.js"`, so the two function names surface at the top level as `me.requestFullscreen()` / `me.exitFullscreen()` — a deprecated shim with runtime warning that points at `Application#requestFullscreen` / `Application#exitFullscreen`. Re-exporting them under `me.device.*` defeated the whole point of "they live in deprecated.js" — it leaked the deprecated names back into the namespace they were moved out of. Users still calling `me.device.requestFullscreen()` directly need to either migrate to `app.requestFullscreen()` (canonical) or drop the `.device.` segment. `device.ts` keeps `hasFullscreenSupport` and `isFullscreen` exposed under `me.device.*` via the new re-export from `system/fullscreen.ts` — those are non-deprecated probes and remain valid public API.

Per the user clarification: implementations stay in `lang/deprecated.js` (correct — that's where the engine's other deprecation surface lives) but the names need to be reachable as `me.device.requestFullscreen` / `me.device.exitFullscreen` for backwards compatibility with consumers still calling through that namespace. Net structure: - `lang/deprecated.js` — function bodies + `warning(...)` runtime call + the four-variant vendor probe - `system/device.ts` — one re-export line so the names appear on `me.device.*`. eslint-disable on the re-export covers the `no-deprecated` rule (which fires when re-exporting deprecated symbols — intentional here, since the whole point is to surface them under the deprecated alias) - `system/fullscreen.ts` — `hasFullscreenSupport` / `isFullscreen` (canonical, non-deprecated), imported by BOTH device.ts and lang/deprecated.js.

The named `NavigatorLike` alias would have shown up in the published types as a brand-new engine-defined type — making any later rename / removal a breaking change. Inlined the navigator shape as `Partial> | undefined` so only DOM-lib types appear in the signature. The `@internal` tag still flags the predicate as test-seam-only for TypeDoc (`--exclude Internal`), and the contract under test is unchanged.
