Fixes #1554
Fixes #1271

Changes

  • Add PhysicsScene.raycastAll using the existing HitResult, layerMask, and isSceneQuery path; hit order remains unspecified.
  • Consume the upstream custom callback collector so raycast and overlap all-hit queries collect every native touch chunk in one query.
  • Preserve the existing physics binding method signatures; no new API, cap increase, Engine retry, overflow flag, or compatibility fallback.
  • Correct ColliderShape.isSceneQuery documentation to cover raycasts, shape casts, and overlap queries.
  • Release every Embind vector element returned by get(i) in normal and callback-throw paths, then release the vector itself.
  • Regenerate and commit the standard/SIMD PhysX runtime files consumed by both Engine and e2e.

Upstream dependency

The runtime binding is galacean/physX.js#22, now updated to 7adf6fe686da90a07bca6c93f44b01969d601a91. That PR must be merged and its four immutable standard/SIMD JS/WASM assets published before the Engine default CDN can be updated. The current default CDN remains unchanged; this is the only remaining external release blocker.

Validation

  • Chromium targeted 257-overlap test: 1/1
  • HEADLESS=true vitest run tests/src/core/physics/PhysicsScene.test.ts: 54/54
  • physics-physx TypeScript check: passed
  • Prettier check: passed
  • pnpm lint: 0 errors, 1623 existing warnings
  • Embind vector element ownership and callback-failure recovery: passed
  • SHA256 comparison: all standard/SIMD JS/WASM files match byte-for-byte from physX.js/wasm_build to packages/physics-physx/libs and e2e/.dev

No merge, auto-merge, CDN publication, or default URL change was performed.

Summary by CodeRabbit

  • New Features

    • Added multi-hit raycasting to retrieve every intersected shape along a ray.

Walkthrough

The physics scene APIs now support multi-hit raycasts. The core collects HitResult objects, while the PhysX backend uses raycastMultiple with filtering, a 256-hit limit, and native resource cleanup. Tests cover filtering, callback errors, overlap cleanup, and more than 256 hits.

Changes

Multi-hit raycast support

Layer / File(s) Summary
Raycast-all contract and result collection
packages/design/src/physics/IPhysicsScene.ts, packages/core/src/physics/PhysicsScene.ts, packages/core/src/physics/shape/ColliderShape.ts
Adds the raycastAll API. The core clears and populates the caller’s result array. The onHit callback is required. The isSceneQuery documentation covers raycasts, shape casts, and overlap queries.
PhysX multi-hit execution
packages/physics-physx/src/PhysXPhysicsScene.ts
Adds a dedicated NO_BLOCK filter, executes raycastMultiple for up to 256 hits, forwards hit data, and releases each native hit and collection. It also applies per-hit cleanup to _overlapMultiple.
Raycast-all and overlap validation
tests/src/core/physics/PhysicsScene.test.ts
Tests multiple hits, distance and layer filters, zero-distance queries, scene-query-disabled shapes, required callbacks, callback errors, 257 raycast hits, and 257-shape overlap queries.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to e3127

The change adds all-hit raycasts and complete native hit collection, but using the new behavior in the default runtime still depends on publishing the updated PhysX assets separately. The PR is mergeable with explicit owner awareness that release adoption must wait for that dependency.

Blocker fixes pushed in a0cd7b8.

  • The upstream all-hit path now streams processTouches chunks through one custom PxRaycastCallbackCollector; the previous Ext -1 retry could not observe eNO_BLOCK touch-buffer clipping.
  • raycastAll now deletes each Embind get(i) PxRaycastHit copy in a local finally, including when the hit callback throws.
  • _overlapMultiple now uses the same element finally cleanup and keeps vector deletion in an outer finally.
  • The focused PhysicsScene test now creates 257 hit shapes and verifies count plus every shape/entity identity.

中央独立复核通过当前 head a0cd7b8,无 blocker。raycastAll 通过 upstream collector 一次 query 收齐全部 touch;主线程复跑 PhysicsScene 53/53,257-hit case 校验全部 shape/entity identity。Embind Vector get(i) 的拥有型 copy 在 raycastAll 与 overlapMultiple 中均由局部 finally 删除,vector 由外层 finally 删除;回调异常也不会泄漏。四份 standard/SIMD Engine/e2e 产物与 physX.js wasm_build SHA256 完全一致。#1271 仅修正文档是正确结论:isSceneQuery 实际控制 raycast、shape cast 与 overlap,不应重命名。未合并、未启用自动合并。

结论

P0 阻塞。本轮完整复核了 dev/2.0@490d2bc8 到目标 HEAD a0cd7b808297dba1ba5438b0e90f19f646cb7bd8 的全量 diff,并增量核对了 cfc261ac...a0cd7b80 的 blocker 修复;代码内的新 binding 与资源释放已闭环,但默认用户加载的 PhysX runtime 仍是旧协议,raycastAll() 会必现调用不存在的方法。本次实际 review 动作为 REQUEST_CHANGES,目标 HEAD 为 a0cd7b808297dba1ba5438b0e90f19f646cb7bd8。自动 CR 不替代人工 Reviewer 的合入门禁;修复后仍需人工 Reviewer 审核并决定是否 APPROVE。

已关闭问题清单

  • eNO_BLOCK 下固定 touch buffer 会截断全量命中 — 已由上游 galacean/physX.js#22@bb070c3 修复:权威 PxScene::raycast 路径改为 PxRaycastCallbackCollector::processTouches 连续收集每个 chunk,删除无效的 Ext overflow retry;本 PR 的 257-hit 公开链路测试逐一核对 shape/entity identity,能够反向守住该问题。
  • Embind vector.get(i) 返回拥有型 copy,逐命中泄漏 — 已由 a0cd7b80 修复:raycastAll_overlapMultiple 均在元素级 finally 删除 copy,并由外层 finally 删除 vector;回调抛错路径也完成释放。

问题

  1. [P0] 默认 PhysX runtime 仍是旧协议,默认配置下 raycastAll() 必现崩溃packages/physics-physx/src/PhysXPhysics.ts:66-73 仍指向原 standard/SIMD CDN URL,而新调用已经在 packages/physics-physx/src/PhysXPhysicsScene.ts:293 直接执行 _pxScene.raycastMultiple(...)。我实际加载两份默认 CDN 模块后,standard 与 SIMD 的 typeof PxScene.prototype.raycastMultipletypeof VectorPxRaycastHit 都是 undefined;同样检查本 PR 提交的两套本地产物则都是 function。因此用户按默认方式 new PhysXPhysics() 初始化后调用公开 PhysicsScene.raycastAll(),会得到 _pxScene.raycastMultiple is not a function,新功能不可用。现有测试在 tests/src/core/physics/PhysicsScene.test.ts:23-24,130-133 显式覆盖 URL 指向仓库内产物,所以 CI 绿无法发现这个真实发布路径断裂。请先合入上游 source owner galacean/physX.js#22@bb070c3,将本 PR 的 standard/SIMD 四个配对文件(JS + WASM)发布到新的不可变 URL,更新这里的两个默认入口,并从 CDN 回读核对 SHA256 与 packages/physics-physx/libs / e2e/.dev 的提交产物完全一致;同时补一条默认 runtime contract/发布守卫。不要在生产代码里为旧 CDN 增加 raycastSingle fallback 或 compatibility branch。

  2. [P2] raycastAll 把唯一输出回调声明成可选,增加了无可观察结果的空语义packages/design/src/physics/IPhysicsScene.ts:76-81 的方法返回 void,却允许省略 onHitPhysXPhysicsScene.ts:306 因而保留 if (hit && hits) 分支。省略时仍执行完整 native 查询和分配,随后丢弃全部结果;而唯一生产调用方 PhysicsScene.raycastAll 始终提供回调。请让 IPhysicsSceneonHit 成为必选契约,删除后端的 hit 可选态与对应分支,并在该公开接口 TSDoc 中补齐四个 @param。应保留的 owner 是 IPhysicsScene.raycastAll 的“逐命中回调”契约,不需要第二种无结果模式。

架构、熵增与测试治理

上游数据流是 Ray + layerMask + ColliderShape.isSceneQuery 进入 Core PhysicsScene;Core 是过滤规则与 HitResult 映射的 owner。下游由 PhysXPhysicsScene 拥有同步查询和 Embind 生命周期,再由 physX.js binding 拥有 PhysX touch 分块协议。本 PR 用 _setHitResult 合并了单命中/全命中的重复映射,新的 _pxRaycastAllFilterData 是热路径复用的单一 filter policy,且上游 collector 已替换并删除旧 Ext retry;这些部分没有新增平行状态机或 legacy 路径。

当前真正的熵增发生在发布协议:上游 source 与仓库内 standard/SIMD 产物已经升级到 raycastMultiple,默认 CDN 仍停留在旧契约,形成两版 runtime 真相。应保留 physX.js 合入 commit 作为源码 owner、由 PhysXPhysics 默认 URL 指向的不可变 CDN build 作为发布 owner,并机械校验 packages/physics-physx/libse2e/.dev 两份投影;删除旧 URL 引用,不增加同步层或 fallback。257-hit 测试是有效的公开链路回归,但它只消费本地产物;必须补默认 runtime/发布边界守卫,才能覆盖本次 P0。现有 fixture/mock/snapshot 未锁定已退场契约,也没有理由为旧测试保留 compatibility branch。

P2 addressed in e8e711a.\n\n- IPhysicsScene.raycastAll now requires onHit and documents all four parameters.\n- PhysXPhysicsScene uses the same required name and no longer keeps the no-output callback branch.\n- Full-repo rg found one production caller, PhysicsScene.raycastAll, which always supplies the callback; PhysXPhysicsScene is the only backend implementation. No mock, example, docs, or supported Galacean default-branch consumer relies on omitting it.\n- The existing physics contract test now proves a hit-producing call without the callback does not silently succeed, then verifies the required callback receives both shape IDs.\n\nLocal validation:\n- HEADLESS=true node_modules/.bin/vitest run tests/src/core/physics/PhysicsScene.test.ts: 53/53 passed in Chromium against rebuilt 2.0.0-alpha.43 modules.\n- pnpm build: passed, including module build and all package declaration tsc tasks.\n- pnpm lint: exit 0, 0 errors; existing repository warnings remain.\n- Prettier check and git diff --check: passed.\n- Generated IPhysicsScene and PhysXPhysicsScene declarations both show a required fourth parameter.\n\nRemote readback: PR head and refs/heads/codex/issue-1554 both resolve to e8e711a. New-head CI is green: lint, Linux/macOS/Windows builds, all four E2E shards, codecov job, codecov project/patch, and labeler passed.\n\nP0 intentionally remains open and unchanged. The default standard and SIMD CDN runtimes still expose neither PxScene.prototype.raycastMultiple nor VectorPxRaycastHit, while both committed local runtime pairs expose them. galacean/physX.js#22 remains OPEN / REVIEW_REQUIRED at bb070c3f7219c18bd02e0b034e8710829e5e72d6. This PR must remain blocked until #22 is merged, four immutable JS/WASM artifacts are published, default URLs and hashes are updated, and a default-runtime release guard is added. No old-runtime fallback or capability-probe workaround was added; no merge, auto-merge, or CDN publication was performed.

中央复核当前 HEAD e8e711a927851cbf99e18b4322475bdd43983335:上一轮 P2 已收掉,IPhysicsScene.raycastAll 的唯一输出回调现为必选,PhysX 后端删除无结果分支并补齐公开 TSDoc;主线程独立复跑 PhysicsScene 53/53 通过。P0 仍是发布边界 blocker:上游 physX.js#22 当前仍 OPEN / REVIEW_REQUIRED,四份 standard/SIMD JS/WASM 尚未发布到新的不可变 CDN URL,因此本 PR 不能通过 fallback 绕开,也还不能视为可合入。未合并、未启用自动合并。

Update the default PhysX runtime URLs before enabling raycastAll.

initialize() loads the default standard or SIMD CDN pair. Neither paired WASM module exposes raycastMultiple or VectorPxRaycastHit. raycastAll calls _pxScene.raycastMultiple(...) without a capability check, so it can fail before returning hits.

  • raycastAlleNO_BLOCK 下被固定 touch buffer 截断 — 已由上游 galacean/physX.js#22@bb070c3 修复:PxRaycastCallbackCollector::processTouches 连续收集各 chunk,Engine 的 257-hit 公开链路测试逐一覆盖 shape/entity identity。

问题

  1. [P0] 默认 PhysX runtime 仍是旧协议,默认配置下 raycastAll() 必现崩溃packages/physics-physx/src/PhysXPhysics.ts:66-73 仍指向旧 standard/SIMD CDN pair,而 packages/physics-physx/src/PhysXPhysicsScene.ts:293 已无条件调用 _pxScene.raycastMultiple(...)。我在提交前重新加载了这两个默认模块:两者的 PxScene.prototype.raycastMultipleVectorPxRaycastHit 均为 undefined;目标 HEAD 提交的 standard/SIMD 模块则均为 function。默认 CDN 四文件的 SHA256 仍与 dev/2.0 产物相同,也与本 PR 新产物不同,所以 new PhysXPhysics() 用户会得到 _pxScene.raycastMultiple is not a functiontests/src/core/physics/PhysicsScene.test.ts:24-26,127-135 显式覆盖 URL 到仓库内产物,当前全绿 CI 无法覆盖该发布断层。请先合入 galacean/physX.js#22@bb070c3,将 standard/SIMD 的 JS + WASM 配对产物发布到新的不可变 URL,更新两个默认入口,从 CDN 回读校验四份 SHA256 与 packages/physics-physx/libs / e2e/.dev 完全一致,并补构建/发布侧默认 runtime contract guard。应保留 physX.js commit 作为源码 owner、PhysXPhysics 默认 URL 作为发布 owner;删除旧 URL 引用,不要增加旧 runtime fallback、capability compatibility branch 或第二条查询路径。

  2. [P0] 同一 all-hit 根因仍留在 overlap*All,超过 256 个重叠 shape 会静默缺失packages/physics-physx/src/PhysXPhysicsScene.ts:576-600_overlapMultiple 仍把 256 作为 overlapMultiple 的结果 buffer 上限;上游 SceneBinding.h:245-255 仍调用 PxSceneQueryExt::overlapMultiple 并直接返回这段固定 vector。PhysX 真源在 ExtSceneQueryExt.cpp:155-173 强制 eNO_BLOCK,而 PxHitBuffer 的固定 touch buffer overflow 会任意丢弃后续 touch 且不报错。用目标 HEAD 提交的 standard runtime 放入 257 个同时重叠的 box 后,我实际得到 returned=256, unique=256;Core 的 overlapBoxAll / overlapSphereAll / overlapCapsuleAll 只会映射这些 ID,调用方既看不到容量也看不到 overflow。此项不是重提已关闭的 raycast collector:raycast 路径已改为分块 collector,残留的是本 PR 在 a0cd7b80 直接修改资源 ownership 的 sibling overlap 路径。请让 physX.js 的直接 callback collector 成为 all-hit 唯一 owner,将 collector 机械复用于 PxOverlapHit,删除 PxSceneQueryExt::overlapMultiple 的固定结果路径,让 256 只表示 chunk size;随后重建四份 runtime,并补一条从公开 overlap*All 入口验证 257 个 shape identity 的反向测试。不要用提高常量、截断标记或 Engine 侧重试形成第二套协议。

架构、熵增与测试治理

上游 PhysicsSceneLayer + ColliderShape.isSceneQuery 过滤与 HitResult 映射的 owner;IPhysicsScene 只拥有后端回调契约;PhysXPhysicsScene 拥有同步查询、可复用 filter data 与 Embind 生命周期;physX.js 拥有 PhysX touch 分块协议;PhysXPhysics 默认 URL 则是用户实际加载版本的发布 owner。e8e711a9 删除了可选回调模式,_setHitResult 合并了单命中/全命中的重复转换,独立 _pxRaycastAllFilterData 只承载 NO_BLOCK 的差异策略,这些改动没有新增镜像状态或 compatibility 分支。

当前净熵增有两处:源码/仓库产物已经是新 binding、默认 CDN 仍是旧 binding,形成两版 runtime 真相;同一“返回全部 touch”事实又由 raycast collector 与 overlap 固定 Ext buffer 两条协议分别拥有。前者应以新不可变 CDN pair 收口,后者应以 physX.js callback collector 收口并删除固定结果路径。Engine/e2e 的四份产物当前分别共享相同 blob,适合作为机械投影而不是独立 owner。257-hit raycast 测试是有效公开链路测试,回调契约测试没有迫使生产代码保留旧可选分支;但还缺 257-overlap 链路测试与默认 runtime 发布守卫。现有 fixture/mock/snapshot 没有锁定已退场契约,也没有理由为旧测试保留 fallback、wrapper 或第二条转换/校验路径。

Updated at e312778389e162f949aa2bd8facc132e6521385a, pushed non-force.

This update consumes physX.js PR #22 at 7adf6fe686da90a07bca6c93f44b01969d601a91. The public overlapBoxAll/overlapSphereAll/overlapCapsuleAll path now preserves all 257 identities; the focused PhysicsScene suite is 54/54, including Embind element/vector cleanup and callback-throw recovery. Standard/SIMD JS+WASM files in packages/physics-physx/libs and e2e/.dev match physX.js/wasm_build byte-for-byte.

No binding signature or default CDN URL changed. The sole remaining external blocker is upstream merge followed by immutable publication of the four runtime assets, after which the default CDN URLs can be updated and read back. No merge, auto-merge, or CDN publication was performed.

Current-head re-review at e312778: the overlapAll truncation P0 is closed. Engine consumes physX.js 7adf6fe6 artifacts byte-for-byte in packages and e2e, public box, sphere, and capsule overlapAll preserve all 257 shape identities, callback-throw cleanup is covered, PhysicsScene passes 54/54, physics-physx tsc and all substantive CI builds and E2E shards pass. One P0 remains outside this commit: the default CDN still serves the old protocol and must only be changed after physX.js PR 22 is merged and four immutable runtime assets are published and read back.

结论

P0 阻塞。本轮以 dev/2.0@490d2bc8 为 merge base 完整复核了目标 HEAD e312778389e162f949aa2bd8facc132e6521385a 的全量 diff,并增量核对了 e8e711a9...e3127783:上一轮 overlap 截断 P0 已关闭,除仍开放的默认 PhysX runtime 发布断层外,未发现新的 P0/P1/P2。本次实际 review 动作为 REQUEST_CHANGES,目标 HEAD 为 e312778389e162f949aa2bd8facc132e6521385a。自动 CR 不替代人工 Reviewer 的合入门禁;修复后仍需人工 Reviewer 审核并决定是否 APPROVE。

已关闭问题清单

  • raycastAlleNO_BLOCK 下被固定 touch buffer 截断 — 已由上游 galacean/physX.js#22@bb070c3 修复:PxRaycastCallbackCollector::processTouches 连续收集各 chunk,Engine 的 257-hit 公开链路测试逐一覆盖 shape/entity identity。
  • Embind vector.get(i) 返回拥有型 copy,逐命中泄漏 — 已由 a0cd7b80 修复:raycastAll_overlapMultiple 都在元素级 finally 删除 copy,并由外层 finally 删除 vector;回调/映射抛错路径也能释放。
  • raycastAll 的唯一输出回调被声明为可选 — 已由 e8e711a9 修复:IPhysicsScene.raycastAllonHit 成为必选并补齐四个 TSDoc @param,PhysX 后端删除无输出分支;唯一生产调用方始终提供回调。
  • overlap*All 超过 256 个 shape 时静默截断 — 已由本轮 e3127783 消费上游 galacean/physX.js#22@7adf6fe6 修复:PxQueryCallbackCollector<HitType> 现在是 raycast/overlap 分块协议的唯一 owner,旧 PxSceneQueryExt::overlapMultiple 固定结果路径已删除;目标 package/e2e 的 standard/SIMD 资产分别共享相同 Git blob,CI 的公开 box/sphere/capsule 链路均保留 257 个 shape identity,PhysicsScene 54/54 通过。

问题

  1. [P0] 默认 PhysX runtime 仍停留在旧协议,默认配置调用 raycastAll() 必现崩溃packages/physics-physx/src/PhysXPhysics.ts:68-73 仍指向旧 standard/SIMD CDN pair,而 packages/physics-physx/src/PhysXPhysicsScene.ts:293 已无条件调用 _pxScene.raycastMultiple(...)。本轮重新实例化四个模块后,目标 HEAD 的 standard/SIMD 均暴露 PxScene.prototype.raycastMultipleVectorPxRaycastHit,两个默认 CDN 模块则两项均为 undefined;默认 CDN 的 JS/WASM 四文件仍与 dev/2.0@490d2bc8 逐字节相同、与目标产物不同。因此用户以 new PhysXPhysics() 使用默认 URL 时会得到 _pxScene.raycastMultiple is not a functiontests/src/core/physics/PhysicsScene.test.ts:24-26,127-135 显式覆盖 URL 到仓库内产物,所以当前 54/54 与 100% patch coverage 都无法覆盖这个发布边界。请先合入 source owner galacean/physX.js#22@7adf6fe6,发布新的不可变 standard/SIMD JS + WASM 配对资产,更新 PhysXPhysics 的两个默认入口,并从 CDN 回读校验四份 SHA256 与 packages/physics-physx/libs / e2e/.dev 完全一致;同时在构建/发布侧增加默认 runtime contract guard。应保留 physX.js 作为 binding 源码 owner、不可变 CDN pair 作为发布产物、PhysXPhysics 默认 URL 作为发布指针;删除旧 URL 引用,不要增加旧 runtime fallback、capability compatibility branch、wrapper 或第二条查询路径。

架构、熵增与测试治理

数据流已核对为:调用方把 Ray + distance + layerMask + result array 交给 Core PhysicsScene;Core 是 Layer / isSceneQuery 过滤及 HitResult 映射的 owner;IPhysicsScene 只拥有逐命中后端契约;PhysXPhysicsScene 拥有同步查询、filter data 与 Embind 生命周期;physX.js 拥有 PhysX touch 分块收集协议;PhysXPhysics 的默认 URL 则决定用户实际加载的发布版本。下游只消费 Core 映射后的 shape/entity/point/normal,不再重复转换。

相对上一轮,all-hit 协议已从“raycast collector + overlap 固定 Ext buffer”两条路径收口为一个泛型 collector,删除了重复协议;必选回调、共享 _setHitResult 和逐元素释放也没有引入镜像状态、平行状态机或 compatibility 分支。Engine package 与 e2e 资产是同一构建的机械投影,不是独立 owner。当前唯一净熵增仍是仓库源码/本地产物已经升级、默认 CDN 仍是旧 binding,形成两版 runtime 真相;应通过发布新 pair 并删除旧 URL 引用收口,而不是在 Engine 再加同步层或 fallback。

测试治理方向正确:257-raycast 与三种 257-overlap 都从公开入口验证完整 identity,异常测试覆盖元素/vector 清理,CI 在 build 后运行当前产物并得到 PhysicsScene 54/54、全量 1689/1689,修改行 patch coverage 为 100%。现有 fixture/mock/snapshot 没有锁定已退场契约,生产代码也未为旧测试保留 legacy 路径;唯一缺口是这些测试主动覆盖成本地产物,尚不能守住默认 CDN 发布契约。
