The plan's Task 2 code block still showed moverFlags: ObjectInfoState.None; the
shipped code (fcea05f) and spec §5.1 use IsViewer|PathClipped|FreeRotate|
PerfectClip (retail init_object(player, 0x5c)). Update the stale snippet so the
plan matches reality (this stale block was the likely source of a re-report).

# A8.F Swept-Sphere Camera Collision — Implementation Plan
|
|
|
|
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
|
|
|
|
**Goal:** Stop the 3rd-person camera eye from clipping through walls by sweeping a 0.3 m collision sphere from the head-pivot to the desired eye and publishing the stopped position — porting retail's `SmartBox::update_viewer` spring arm. This stabilizes the A8.F indoor-visibility decisions (which key off the eye) and fixes the flap / missing-wall symptoms.
|
|
|
|
**Architecture:** A narrow `ICameraCollisionProbe` is injected into `RetailChaseCamera`. After the camera damps the desired eye and before it publishes, it asks the probe to sweep `pivot→eye`. The concrete `PhysicsCameraCollisionProbe` wraps the existing `PhysicsEngine.ResolveWithTransition`, which already collides against both indoor cell walls (`FindEnvCollisions`) and outdoor/baked GfxObj shells (`FindObjCollisions`). Gated by `CameraDiagnostics.CollideCamera` (default ON).
|
|
|
|
**Tech Stack:** C# / .NET 10, Silk.NET, xUnit. Spec: `docs/superpowers/specs/2026-05-29-a8f-camera-collision-design.md`.
|
|
|
|
**Reference (read before starting):**
|
|
- Spec: `docs/superpowers/specs/2026-05-29-a8f-camera-collision-design.md`
|
|
- Camera: `src/AcDream.App/Rendering/RetailChaseCamera.cs` (eye `:113`, damp `:131`, publish `:136`, fade `:367`)
|
|
- Engine: `src/AcDream.Core/Physics/PhysicsEngine.cs:589` (`ResolveWithTransition`, returns `sp.CheckPos` as `.Position` at `:846`/`:865`)
|
|
- Sphere convention: `src/AcDream.Core/Physics/TransitionTypes.cs:517-547` (`InitPath` sets `LocalSphere[0].Origin = (0,0,radius)`)
|
|
- Player self-skip: `src/AcDream.App/Input/PlayerMovementController.cs` (`CellId` `:133`, `LocalEntityId` `:144`)
|
|

|
|
|
## Task 1: Add `CameraDiagnostics.CollideCamera` flag
|
|
|
|
**Files:**
|
|
- Modify: `src/AcDream.Core/Rendering/CameraDiagnostics.cs`
|
|
- Test: `tests/AcDream.Core.Tests/Rendering/CameraDiagnosticsTests.cs`
|
|
|
|
- [ ] **Step 1: Write the failing test**
|
|
|
|
Add to `CameraDiagnosticsTests.cs` (inside the `CameraDiagnosticsTests` class):
|
|
|
|
```csharp
|
|
[Fact]
|
|
public void CollideCamera_DefaultOn_AndPersistsRuntimeChanges()
|
|
{
|
|
CameraDiagnostics.CollideCamera = true;
|
|
Assert.True(CameraDiagnostics.CollideCamera);
|
|
|
|
CameraDiagnostics.CollideCamera = false;
|
|
Assert.False(CameraDiagnostics.CollideCamera);
|
|
|
|
CameraDiagnostics.CollideCamera = true; // reset so other tests aren't poisoned
|
|
}
|
|
```
|
|
|
|
- [ ] **Step 2: Run test to verify it fails**
|
|
|
|
Run: `dotnet test tests/AcDream.Core.Tests/AcDream.Core.Tests.csproj --filter "FullyQualifiedName~CameraDiagnosticsTests.CollideCamera_DefaultOn"`
|
|
Expected: FAIL — compile error, `CollideCamera` does not exist.
|
|
|
|
- [ ] **Step 3: Add the property**
|
|
|
|
In `CameraDiagnostics.cs`, add after the `UseRetailChaseCamera` property (after line 28):
|
|
|
|
```csharp
|
|
/// <summary>
|
|
/// When true (default), the chase camera sweeps a 0.3 m collision
|
|
/// sphere from the head-pivot to the desired eye and stops it at the
|
|
/// first wall (retail <c>SmartBox::update_viewer</c> spring arm), so
|
|
/// the eye never sits behind/inside geometry. Initial state from
|
|
/// <c>ACDREAM_CAMERA_COLLIDE</c>; default-on if unset, off only when
|
|
/// explicitly set to <c>"0"</c>.
|
|
/// </summary>
|
|
public static bool CollideCamera { get; set; } =
|
|
Environment.GetEnvironmentVariable("ACDREAM_CAMERA_COLLIDE") != "0";
|
|
```
|
|
|
|
- [ ] **Step 4: Run test to verify it passes**
|
|
|
|
Run: `dotnet test tests/AcDream.Core.Tests/AcDream.Core.Tests.csproj --filter "FullyQualifiedName~CameraDiagnosticsTests.CollideCamera_DefaultOn"`
|
|
Expected: PASS.
|
|
|
|
- [ ] **Step 5: Commit**
|
|
|
|
```bash
|
|
git add src/AcDream.Core/Rendering/CameraDiagnostics.cs tests/AcDream.Core.Tests/Rendering/CameraDiagnosticsTests.cs
|
|
git commit -m "feat(render): Phase A8.F — add CameraDiagnostics.CollideCamera flag (default on)"
|
|
```

## Task 2: Camera-collision probe interface + `PhysicsCameraCollisionProbe`
|
|
|
|
**Files:**
|
|
- Create: `src/AcDream.App/Rendering/ICameraCollisionProbe.cs`
|
|
- Create: `src/AcDream.App/Rendering/PhysicsCameraCollisionProbe.cs`
|
|
- Test: `tests/AcDream.App.Tests/Rendering/PhysicsCameraCollisionProbeTests.cs`
|
|
|
|
- [ ] **Step 1: Write the failing test**
|
|
|
|
Create `tests/AcDream.App.Tests/Rendering/PhysicsCameraCollisionProbeTests.cs`:

{
|
|
// The probe must convert the desired eye path (where the SPHERE CENTER
|
|
// should travel) into the foot-capsule path InitPath expects (which offsets

Expected: FAIL — `ICameraCollisionProbe` / `PhysicsCameraCollisionProbe` do not exist.
|
|
|
|
- [ ] **Step 3: Create the interface**
|
|
|
|
Create `src/AcDream.App/Rendering/ICameraCollisionProbe.cs`:

|
|
|
```csharp

|
using System.Numerics;
|
|
|
|
namespace AcDream.App.Rendering;

Vector3 SweepEye(Vector3 pivot, Vector3 desiredEye, uint cellId, uint selfEntityId);
|
|
}
|
|
```
|
|
|
|
- [ ] **Step 4: Create the implementation**
|
|

|
## Task 3: Wire the probe into `RetailChaseCamera`
|
|
|
|
**Files:**
|
|
- Modify: `src/AcDream.App/Rendering/RetailChaseCamera.cs` (property, `Update` signature, sweep call)
|
|
- Test: `tests/AcDream.App.Tests/Rendering/RetailChaseCameraTests.cs`
|
|
|
|
- [ ] **Step 1: Write the failing tests**
|
|
|
|
Add to `RetailChaseCameraTests.cs` (inside the class). These need a fake probe and exercise `Update`:
|
|
|
|
```csharp
|
|
// ── Camera collision (A8.F) ───────────────────────────────────────
|
|
|
|
private sealed class FakeProbe : ICameraCollisionProbe
|
|
{
|
|
public int Calls;
|
|
public Vector3 ReturnEye;
|
|
public Vector3 SweepEye(Vector3 pivot, Vector3 desiredEye, uint cellId, uint selfEntityId)
|
|
{
|
|
Calls++;
|
|
return ReturnEye;
|
|
}
|
|
}
|
|
|
|
[Fact]
|
|
public void Update_WithProbeAndFlagOn_PublishesCollidedEye()
|
|
{
|
|
CameraDiagnostics.CollideCamera = true;
|
|
var collided = new Vector3(1f, 2f, 3f);
|
|
var probe = new FakeProbe { ReturnEye = collided };
|
|
var cam = new RetailChaseCamera { CollisionProbe = probe };
|
|
|
|
cam.Update(
|
|
playerPosition: Vector3.Zero, playerYaw: 0f, playerVelocity: Vector3.Zero,
|
|
isOnGround: true, contactPlaneNormal: Vector3.UnitZ, dt: 1f / 60f,
|
|
cellId: 0x100, selfEntityId: 0x5);
|
|
|
|
Assert.True(probe.Calls >= 1);
|
|
Assert.Equal(collided, cam.Position);
|
|
}
|
|
|
|
[Fact]
|
|
public void Update_FlagOff_DoesNotConsultProbe()
|
|
{
|
|
CameraDiagnostics.CollideCamera = false;
|
|
var probe = new FakeProbe { ReturnEye = new Vector3(99f, 99f, 99f) };
|
|
var cam = new RetailChaseCamera { CollisionProbe = probe };
|
|
|
|
cam.Update(
|
|
playerPosition: Vector3.Zero, playerYaw: 0f, playerVelocity: Vector3.Zero,
|
|
isOnGround: true, contactPlaneNormal: Vector3.UnitZ, dt: 1f / 60f,
|
|
cellId: 0x100, selfEntityId: 0x5);
|
|
|
|
Assert.Equal(0, probe.Calls);
|
|
Assert.NotEqual(new Vector3(99f, 99f, 99f), cam.Position);
|
|
|
|
CameraDiagnostics.CollideCamera = true; // reset
|
|
}
|
|
|
|
[Fact]
|
|
public void Update_NullProbe_DoesNotThrow()
|
|
{
|
|
CameraDiagnostics.CollideCamera = true;
|
|
var cam = new RetailChaseCamera { CollisionProbe = null };
|
|
|
|
// Should run with no collision and publish a valid view.
|
|
cam.Update(
|
|
playerPosition: Vector3.Zero, playerYaw: 0f, playerVelocity: Vector3.Zero,
|
|
isOnGround: true, contactPlaneNormal: Vector3.UnitZ, dt: 1f / 60f,
|
|
cellId: 0x100, selfEntityId: 0x5);
|
|
|
|
Assert.NotEqual(default, cam.View);
|
|
}
|
|
```
|
|
|
|
- [ ] **Step 2: Run tests to verify they fail**
|
|
|
|
Run: `dotnet test tests/AcDream.App.Tests/AcDream.App.Tests.csproj --filter "FullyQualifiedName~RetailChaseCameraTests.Update_"`
|
|
Expected: FAIL — `CollisionProbe` property and the `cellId`/`selfEntityId` `Update` parameters do not exist.
|
|
|
|
- [ ] **Step 3: Add the `CollisionProbe` property**
|
|
|
|
In `RetailChaseCamera.cs`, add to the public tunables region (after the `PivotHeight` property, around line 53):
|
|
|
|
```csharp
|
|
/// <summary>
|
|
/// Optional spring-arm collision probe. When set (and
|
|
/// <see cref="CameraDiagnostics.CollideCamera"/> is true), the damped eye
|
|
/// is swept from the head-pivot and stopped at the first wall. Null leaves
|
|
/// the eye uncollided (the default for tests and the legacy path).
|
|
/// </summary>
|
|
public ICameraCollisionProbe? CollisionProbe { get; init; }
|
|
```
|
|
|
|
- [ ] **Step 4: Extend the `Update` signature**
|
|
|
|
In `RetailChaseCamera.cs`, change the `Update` signature (line 86-92) to add two optional params at the end:
|
|
|
|
```csharp
|
|
public void Update(
|
|
Vector3 playerPosition,
|
|
float playerYaw,
|
|
Vector3 playerVelocity,
|
|
bool isOnGround,
|
|
Vector3 contactPlaneNormal,
|
|
float dt,
|
|
uint cellId = 0,
|
|
uint selfEntityId = 0)
|
|
```
|
|
|
|
- [ ] **Step 5: Insert the sweep between damp and publish**
|
|
|
|
In `RetailChaseCamera.cs`, between the end of the damping block (line 133 `}`) and the `// 6. Publish renderer surface.` comment (line 135), insert:
|
|
|
|
```csharp
|
|
|
|
// 5b. Spring-arm collision (A8.F). Retail SmartBox::update_viewer
|
|
// (0x00453ce0) sweeps viewer_sphere from the head-pivot to the
|
|
// desired eye and uses the stopped position. Keeps the eye out of
|
|
// walls so the A8.F camera-cell + portal side-tests stay stable.
|
|
// A null probe or disabled flag leaves the eye unchanged.
|
|
if (CameraDiagnostics.CollideCamera && CollisionProbe is not null)
|
|
_dampedEye = CollisionProbe.SweepEye(pivotWorld, _dampedEye, cellId, selfEntityId);
|
|
```
|
|
|
|
(The fade at step 7, line 140, already reads `_dampedEye`, so it now uses the collided eye automatically.)
|
|
|
|
- [ ] **Step 6: Run tests to verify they pass**
|
|
|
|
Run: `dotnet test tests/AcDream.App.Tests/AcDream.App.Tests.csproj --filter "FullyQualifiedName~RetailChaseCameraTests"`
|
|
Expected: PASS (the new `Update_*` tests plus all existing `Heading_*` / `BuildBasis_*` tests).
|
|
|
|
- [ ] **Step 7: Commit**
|
|
|
|
```bash
|
|
git add src/AcDream.App/Rendering/RetailChaseCamera.cs tests/AcDream.App.Tests/Rendering/RetailChaseCameraTests.cs
|
|
git commit -m "feat(render): Phase A8.F — RetailChaseCamera consumes the camera-collision probe"
|
|
```
|
|
|
|

|
|
|
|
## Task 4: Wire the probe in `GameWindow`
|
|
|
|
**Files:**
|
|
- Modify: `src/AcDream.App/Rendering/GameWindow.cs` (two camera constructions, one `Update` call)
|
|
|
|
No unit test — `GameWindow` wiring is verified by build + the visual acceptance in Task 7.
|
|
|
|
- [ ] **Step 1: Inject the probe at the first construction site**
|
|
|
|
In `GameWindow.cs`, the construction around line 10693 currently reads:
|
|
|
|
```csharp
|
|
_retailChaseCamera = new AcDream.App.Rendering.RetailChaseCamera
|
|
{
|
|
Aspect = _chaseCamera.Aspect,
|
|
};
|
|
```
|
|
|
|
Change it to:
|
|
|
|
```csharp
|
|
_retailChaseCamera = new AcDream.App.Rendering.RetailChaseCamera
|
|
{
|
|
Aspect = _chaseCamera.Aspect,
|
|
CollisionProbe = new AcDream.App.Rendering.PhysicsCameraCollisionProbe(_physicsEngine),
|
|
};
|
|
```
|
|
|
|
- [ ] **Step 2: Inject the probe at the second construction site**
|
|
|
|
In `GameWindow.cs`, the construction around line 10826 currently reads:
|
|
|
|
```csharp
|
|
_retailChaseCamera = new AcDream.App.Rendering.RetailChaseCamera
|
|
{
|
|
Aspect = _window!.Size.X / (float)_window.Size.Y,
|
|
};
|
|
```
|
|
|
|
Change it to:
|
|
|
|
```csharp
|
|
_retailChaseCamera = new AcDream.App.Rendering.RetailChaseCamera
|
|
{
|
|
Aspect = _window!.Size.X / (float)_window.Size.Y,
|
|
CollisionProbe = new AcDream.App.Rendering.PhysicsCameraCollisionProbe(_physicsEngine),
|
|
};
|
|
```
|
|
|
|
- [ ] **Step 3: Pass cell + self-entity into the per-frame `Update`**
|
|
|
|
In `GameWindow.cs`, the camera update around line 6862 currently ends with `dt: (float)dt);`. Change the call to:
|
|
|
|
```csharp

## Task 5: Add the live-toggle menu item
|
|
|
|
**Files:**
|
|
- Modify: `src/AcDream.App/Rendering/GameWindow.cs` (the `Camera` ImGui menu, ~line 7934)
|
|
|
|
- [ ] **Step 1: Add the checkbox menu item**
|
|
|
|
In `GameWindow.cs`, the `Camera` menu (around line 7934) currently reads:
|
|
|
|
```csharp
|
|
if (ImGuiNET.ImGui.BeginMenu("Camera"))
|
|
{
|
|
if (_cameraController is not null)
|
|
{
|
|
string flyLabel = _cameraController.IsFlyMode
|
|
? "Exit Free-Fly Mode" : "Enter Free-Fly Mode";
|
|
if (ImGuiNET.ImGui.MenuItem(flyLabel, "Ctrl+Shift+F"))
|
|
ToggleFlyOrChase();
|
|
}
|
|
ImGuiNET.ImGui.EndMenu();
|
|
}
|
|
```
|
|
|
|
Insert the toggle before `ImGuiNET.ImGui.EndMenu();`:
|
|
|
|
```csharp
|
|
if (ImGuiNET.ImGui.BeginMenu("Camera"))
|
|
{
|
|
if (_cameraController is not null)
|
|
{
|
|
string flyLabel = _cameraController.IsFlyMode
|
|
? "Exit Free-Fly Mode" : "Enter Free-Fly Mode";
|
|
if (ImGuiNET.ImGui.MenuItem(flyLabel, "Ctrl+Shift+F"))
|
|
ToggleFlyOrChase();
|
|
}
|
|
// A8.F: spring-arm camera collision (live A/B toggle).
|
|
if (ImGuiNET.ImGui.MenuItem("Collide Camera (spring arm)", "",
|
|
AcDream.Core.Rendering.CameraDiagnostics.CollideCamera))
|
|
AcDream.Core.Rendering.CameraDiagnostics.CollideCamera =
|
|
!AcDream.Core.Rendering.CameraDiagnostics.CollideCamera;
|
|
ImGuiNET.ImGui.EndMenu();
|
|
}
|
|
```
|
|
|
|
- [ ] **Step 2: Build to verify**
|
|
|
|
Run: `dotnet build`
|
|
Expected: build succeeds (0 errors).
|
|
|
|
- [ ] **Step 3: Commit**
|
|
|
|
```bash
|
|
git add src/AcDream.App/Rendering/GameWindow.cs
|
|
git commit -m "feat(render): Phase A8.F — Camera menu toggle for spring-arm collision"
|
|
```

## Task 6: Correct the prior camera spec's collision note
|
|
|
|
**Files:**
|
|
- Modify: `docs/superpowers/specs/2026-05-18-retail-chase-camera-design.md` (lines 454-457)
|
|
|
|
- [ ] **Step 1: Mark the stale note as superseded**
|
|
|
|
In `2026-05-18-retail-chase-camera-design.md`, replace the bullet at lines 454-457:
|
|
|
|
```markdown
|
|
- **Camera-vs-world collision.** Retail's per-frame update doesn't
|
|
raycast world geometry (see investigation report 2026-05-18 in chat).
|
|
The auto-fade handles "camera passes through player"; we don't
|
|
attempt "camera collides with wall" — same as retail.
|
|
```
|
|
|
|
with:
|
|
|
|
```markdown
|
|
- **Camera-vs-world collision.** ~~Retail's per-frame update doesn't
|
|
raycast world geometry; we don't attempt "camera collides with wall"
|
|
— same as retail.~~ **SUPERSEDED 2026-05-29:** this was a research
|
|
error — retail DOES collide the camera in `SmartBox::update_viewer`
|
|
(0x00453ce0), which the earlier pass missed by tracing only the
|
|
desired-eye producer. Implemented as a swept-sphere spring arm; see
|
|
`docs/superpowers/specs/2026-05-29-a8f-camera-collision-design.md`.
|
|
```
|
|
|
|
- [ ] **Step 2: Commit**
|
|
|
|
```bash
|
|
git add docs/superpowers/specs/2026-05-18-retail-chase-camera-design.md
|
|
git commit -m "docs(render): Phase A8.F — supersede the old 'no camera collision' note"
|
|
```

|
## Task 7: Full verification + acceptance
|
|
|
|
**Files:** none (verification only).
|
|
|
|
- [ ] **Step 1: Full build**
|
|
|
|
Run: `dotnet build`
|
|
Expected: 0 errors.
|
|
|
|
- [ ] **Step 2: Full test suite**
|
|
|
|
Run: `dotnet test`
|
|
Expected: green. Note the App.Tests baseline should increase by the new camera tests; no regressions in Core/Net.
|
|
|
|
- [ ] **Step 3: Visual verification (the real acceptance — requires the user)**
|
|
|
|
Launch against the live ACE server with the A8.F branch on (PowerShell):
|
|
|
|
```powershell
|
|
$env:ACDREAM_DAT_DIR="$env:USERPROFILE\Documents\Asheron's Call"; $env:ACDREAM_LIVE="1"
|
|
$env:ACDREAM_TEST_HOST="127.0.0.1"; $env:ACDREAM_TEST_PORT="9000"
|
|
$env:ACDREAM_TEST_USER="testaccount"; $env:ACDREAM_TEST_PASS="testpassword"
|
|
$env:ACDREAM_A8_INDOOR_BRANCH="1"
|
|
dotnet run --project src\AcDream.App\AcDream.App.csproj --no-build -c Debug 2>&1 | Tee-Object -FilePath "a8f-cameracollide.log"
|
|
```
|
|
|
|
Walk `+Acdream` into a Holtburg cottage and down into its cellar, panning the camera through walls and crossing the doorway inside↔outside. Confirm:
|
|
- the flap is gone — walls/ground stay solid while panning and while crossing the doorway;
|
|
- back walls no longer go missing when looking through a window from outside;
|
|
- the player fades (rather than the camera sitting inside the player mesh) when backed into a corner.
|
|
|
|
Then toggle `Collide Camera (spring arm)` off via the Camera menu (or relaunch with `ACDREAM_CAMERA_COLLIDE=0`) and confirm the flap returns — proving the fix is what closed it.
|
|
|
|
- [ ] **Step 4: Update the roadmap / milestones on visual pass**
|
|
|
|
After the user confirms the visual result, update the A8.F entry in `CLAUDE.md` (the M1.5 "currently working toward" block) and `docs/plans/2026-04-11-roadmap.md` shipped table to note the swept-sphere camera collision shipped + visual-verified, and move/close the related A8.F flap notes. Commit:
|
|
|
|
```bash
|
|
git add CLAUDE.md docs/plans/2026-04-11-roadmap.md
|
|
git commit -m "docs(render): Phase A8.F — camera collision shipped + visual-verified"
|
|
```

## Notes for the implementer
|
|
|
|
- **Do not** re-implement collision in the probe. The whole point of reusing
|
|
`ResolveWithTransition` is that the env+obj sweep is already tested. The probe
|
|
is param-marshalling + the z-offset round trip.
|
|
- **Self-skip is load-bearing.** The sweep starts at the player's head, inside
|
|
the player's own 0.48 m collision sphere / ShadowEntry. Passing
|
|
`selfEntityId` (= `LocalEntityId`) is what stops the eye from snapping onto
|
|
the head every frame. If the eye appears glued to the player, this is the
|
|
first thing to check.
|
|
- **Slide vs hard-stop (open question).** Reusing the transition gives the
|
|
player path's edge-slide (the eye glides along a wall, no jitter). If visual
|
|
verification shows the eye behaving oddly, read retail's `find_valid_position`
|
|
and match its stop/slide semantics — but do not change the architecture for it.
|
|
- **If the eye hugs/penetrates in a tight room**, the spec's optional
|
|
`AdjustPosition` fallback (spec §7) is the escalation; add it only if needed.
