feat: screenshot --annotate-elements lists UI Toolkit controls on screen-space panels - #3308
Merged

Conversation
Annotated screenshots are about to list UI Toolkit controls next to uGUI ones, and a caller needs to tell them apart because only uGUI paths can be fed back to simulate-mouse-ui --target-path. Add a UiSystem field to UIElementInfo and set it to "UGUI" for every uGUI element; PhysicsCollider elements leave it empty. The value strings live in the Screenshot assembly rather than in ToolContracts, which only holds the contract shape.
Unity has no panel-to-screen API, and a PanelSettings can replace the screen-to-panel function with an arbitrary one. To report a control's bounds in screen pixels, sample the forward function at three points to derive a per-axis scale and offset, and check a fourth point to reject functions that are non-linear, sheared, rotated, swapped, or non-finite. A rejected panel cannot have its controls placed on the screenshot.
Map Button/RepeatButton, Toggle/RadioButton, Scroller, the sliders, TextField, and DropdownField/EnumField to the same type words the uGUI annotator uses, so the existing interaction mapping covers both UI systems. Every other element, including plain elements with a Clickable, is not annotated.
Mirror the uGUI reachability check for UI Toolkit: walk the same probe points, skip a point when any panel in front picks something there (Unity routes the input to that panel), and accept the first point where the control's own panel picks the control or one of its descendants. The logic takes picker functions so it can be tested without a panel.
…ettings Creating a PanelSettings in the Editor runs PanelSettings.Reset, which assigns the first ThemeStyleSheet in Assets and, when there is none, writes this default theme and refreshes the AssetDatabase. Committing it keeps tests that create PanelSettings from regenerating it, and the refresh, on every fresh checkout.
Annotated screenshots only listed uGUI elements, so controls on a UIDocument were invisible to agents. Collect them alongside uGUI: - Walk every active top-level UIDocument whose panel shows on the Game View's display and is not world-space; nested documents are reached through their parent's root so nothing is listed twice. - Settle every panel's layout first (Pick is the only public call that validates it), so controls added in the same frame report real bounds. - Report the controls UIToolkitElementClassifier recognizes, skipping disabled, hidden, and display:none subtrees and the parts inside a control such as a Scroller's buttons. - Convert bounds to bottom-left screen pixels with the inverted panel mapping, then probe the same points as uGUI. Panels with a higher sorting order, including ones that render into a texture, cover the control because Unity routes screen input to them first. - Panels rendering into a texture or without an invertible mapping list nothing but still cover others. PlayMode tests build panels in code and pin each row of this behavior; the PlayMode test assembly now references the Screenshot assembly.

243-243: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value
⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Fractional panel sorting orders can mislabel front-to-back order.
PanelSettings.sortingOrderis a float.CreateFrontPickerscompares the raw floats, butSortingOrderis truncated withMathf.FloorToInthere. Two panels with orders 0.2 and 0.7 both getSortingOrder = 0.AssignLabelsthen orders their elements bySiblingIndexonly. As a result, an element on the back panel can receive an earlier label than an element on the front panel. Labels then no longer follow the documented front-to-back order. This edge case is narrow. Coverage between the panels stays correct.

Unity RuntimePanelUtils.ScreenToPanel coordinate system screen position Screen.height panel input official documentation
💡 Result:
Unity’s **Unity 6.0** docs show that `Input.mousePosition` uses screen pixels with the origin at the **bottom-left**, while UI Toolkit panel coordinates use a **top-left** origin. The documented pattern is to flip Y **before** calling `ScreenToPanel`:
```csharp
Vector2 screenPosition = Input.mousePosition;
screenPosition.y = Screen.height - screenPosition.y;
Vector2 panelPosition =
RuntimePanelUtils.ScreenToPanel(panel, screenPosition);
```
`ScreenToPanel` then converts that screen position to the panel’s local coordinates, accounting for panel scaling. So, when using `Input.mousePosition`, don’t pass it unchanged if you need the top-left-origin UI Toolkit position. ([docs.unity3d.com](https://docs.unity3d.com/jp/current/ScriptReference/UIElements.RuntimePanelUtils.ScreenToPanel.html?utm_source=openai))
Citations:
- 1: https://docs.unity3d.com/jp/current/ScriptReference/UIElements.RuntimePanelUtils.ScreenToPanel.html?utm_source=openai
Separate panel-input and response-coordinate heights.
RuntimePanelUtils.ScreenToPanel requires the top-left point produced with Screen.height. The response conversion uses GameViewSize.y. Using one height for both shifts stored UI Toolkit bounds and points, while replacing Screen.height with GameViewSize.y also shifts reachability probes and can make Panel.Pick reject reachable controls.

A screen-to-panel function that mirrors an axis has a negative scale. Inverting it swaps the panel rectangle's minimum and maximum, so the reported bounds had BoundsMin greater than BoundsMax. Treat a negative scale like a zero one: the panel's controls are not listed.
Write each classifier branch as a braced block like the rest of the package, and state in the PlayMode test summary that PanelSettings.Reset assigns the project's default theme, which is why element sizes are set explicitly.
The world-space check only ever ran its "no renderMode property" path: the project's Unity 2022.3 has no PanelSettings.renderMode, and CI's Unity 6 EditMode legs do not run these tests. Move the check into HasWorldSpaceRenderMode, which looks the property up on the object's runtime type, and test it with stand-in types for an internal WorldSpace value, a public screen-space value, and a missing property.

Annotated UI Toolkit controls came out with the wrong Y in a real screenshot (a button at top 100 reported Y -218..-168 in a 1080-high Game View). The collector flipped to a bottom-left origin with Screen.height, but uloop commands run outside the player loop, where Screen reports the last Editor view drawn (1398 high here), while ConvertToSimCoordinates flips back with the Game View height. Pass the Game View height into the collector, the same source the overlay renderer and coordinate conversion use, and stop reading Screen there. PlayMode tests ran inside the player loop, where both heights match, so a new test passes a height unlike Screen.height.

Summary

AnnotatedElementsor on the PNG, so an agent could not find them.Changes
visibility: hidden,display: nonesubtrees, zero-size, fully covered or clipped controls, panels on another display than the Game View, Unity 6 world-space panels, panels rendering into a texture, and nested UIDocuments (reached once through their parent).FindObjectsByType/FindObjectsOfTypeare split with#if UNITY_6000_4_OR_NEWERlike the existing uGUI collector.Assets/UI Toolkit/UnityThemes/UnityDefaultRuntimeTheme.tssis committed: creating a PanelSettings in the Editor generates it when no theme exists, so tests would otherwise regenerate it (and refresh the AssetDatabase) on every fresh checkout.Y flip found in a live run
Screen.height, but uloop commands run outside the player loop, whereScreenreported 1533x1398 (the last Editor view drawn), while the conversion back to top-left uses the Game View height.Screen. PlayMode tests run inside the player loop, where both heights match, so the new test passes a height unlikeScreen.height; the wiring in the annotator is covered by the follow-up E2E PR, which checks real screenshot coordinates.Input space covered by tests
