Walkthrough

This change adds touch-based structure placement with tile-anchored previews and queued build validation. It adds radial-menu click forwarding and guards against stale asynchronous menu results. The unit display is available at all screen sizes and uses a responsive, horizontally scrollable layout.

Changes

Touch Ghost Placement

Layer / File(s) Summary
Touch placement pointer events
src/client/InputHandler.ts, tests/InputHandler.test.ts
Touch input emits ghost-placement events. A handled touch drag moves the preview after reaching the drag threshold. Pointer release and cancellation have separate placement behavior.
Touch preview targeting
src/client/controllers/BuildPreviewController.ts, tests/client/controllers/BuildPreviewController.test.ts
Touch placement selects and anchors a preview tile. Moving the preview refreshes buildability, and mouse movement exits touch mode.
Validated confirmation queue
src/client/controllers/BuildPreviewController.ts, tests/client/controllers/BuildPreviewController.test.ts
Confirmations capture tile and ghost state, then use serialized buildability queries before building. Tests cover queued confirmations, invalid placements, and stale results.

Radial Menu Interaction

Layer / File(s) Summary
Radial click forwarding and slider handling
src/client/InputHandler.ts, src/client/hud/layers/RadialMenu.ts, src/client/hud/layers/ControlPanel.ts, tests/client/RadialMenu.test.ts, tests/client/ControlPanelAttackRatio.test.ts
Overlay clicks forward only when they target a marked element below the overlay. Attack-ratio sliders map forwarded click positions to values.
Stale menu result guard
src/client/hud/layers/MainRadialMenu.ts, tests/client/MainRadialMenu.test.ts
MainRadialMenu ignores action results when the request token changes before an asynchronous response completes.

Responsive Unit Display

Layer / File(s) Summary
Responsive toolbar and tooltip
index.html, src/client/hud/layers/UnitDisplay.ts, src/client/styles.css, tests/client/UnitDisplay.test.ts
The unit display is visible at all screen sizes. The toolbar uses a responsive grid and horizontal scrolling. Tooltip content renders outside the scroller and disappears when its item is disconnected.

The changes are mergeable with bounded follow-up: a narrow touch-release sequence can leave the placement preview unmoved, and the menu-item test needs stronger regression coverage. Tooltip positioning now updates on resize.

Show unit price and description before selection on small screens.

Below the lg breakpoint, this PR makes the unit toolbar visible. Each unit button selects its unit on tap. The button shows only the icon, an lg-only hotkey, and the owned count. The cost and description appear only in the hover tooltip, and that tooltip is hidden lg:block, so it stays hidden below lg. Touch users on small screens therefore cannot see a unit's cost or description before they select it. The radial menu does not supply this information on touch, because its price tooltips appear only on hover.

Show the cost and description before selection on small screens, for example in the button itself.

Assert that no ordinary TouchEvent fires during ghost placement.

The tap test listens only for TouchGhostPlacementEvent. It asserts the placement list and an empty move list, but no assertion covers TouchEvent. The test file does not reference TouchEvent anywhere. If a regression also emits TouchEvent during a ghost tap, the test still passes. Ordinary TouchEvent subscribers can then act on the tap, for example by opening a context menu or showing a player or unit panel. Add a TouchEvent listener to the test and assert that it receives nothing.

Suggested test change
     eventBus.on(TouchGhostPlacementEvent, (event) => placements.push(event));
+    const touches: TouchEvent[] = [];
+    eventBus.on(TouchEvent, (event) => touches.push(event));

Add a snapped-placement confirmation test for the pointer path.

With snapBuildPreview on, resolveGhostPlacement moves the preview to u.canBuild. Pointer and keyboard confirmation (ConfirmGhostStructureEvent with touch mode off) sends a MouseUpEvent at the pointer position. That path queries the pointer tile, and createStructure emits BuildUnitIntentEvent for that same tile. No snap-enabled test asserts the emitted intent tile. A future change that builds on the displayed tile would not fail the current suite.

Add a test that enables snapping, uses a canBuild tile that differs from the pointer tile, and asserts that BuildUnitIntentEvent.tile equals the pointer tile.

Touch confirmation behaves differently. touchPreviewScreenPosition returns the snapped cell center, so touch confirmation re-queries the snapped tile. A touch-path test with snapping should assert that snapped tile, not the original touch query tile.

Add a button-fit check to the mobile quick-build layout test.

The layout test named keeps the quick-build items in one horizontally scrollable row checks only class names and the child count of .grid. A grid whose ten cells overlap at 361–400px would pass every assertion. The test does not measure button bounds or widths. This is a coverage gap, not a currently failing check. Where the environment allows it, add a browser-level layout check, or a width assertion on the rendered buttons, at a viewport just above 360px.

🎯 Functional Correctness | 🟡 Minor | 💤 Low value

Refresh the tooltip position while it is shown; a resize with a still pointer leaves it off-center.

On desktop, the unit grid is centered in its row. A viewport resize shifts each item horizontally by about half the width change. The tooltip keeps the coordinates captured at mouseenter, so it stays at the old position. The pointer must stay over the same item, so no new mouseenter fires and the position does not update until the pointer leaves and re-enters the item.

Assert the narrow-screen grid override in the layout test.

The layout test checks the narrow-screen flow and column width classes, but not max-[360px]:grid-cols-none. Removing that class from src/client/hud/layers/UnitDisplay.ts would not fail this test. The class string is static, so a disabled-unit fixture is not needed to cover it. Add the assertion to the existing layout test.

Add position assertions to the desktop tooltip test.

The test at tests/client/UnitDisplay.test.ts:55-71 checks only that a tooltip exists and sits outside .unit-display-scroll. It does not check the tooltip's left or top values. A regression in tooltip placement would still pass this test.

The hover handler sets the tooltip position from bounding rectangles. It computes left from the item's center minus the root's left edge, and top from the item's top minus the root's top minus 4px. Without mocked rectangles, jsdom returns zeros for both elements. Then a regression that drops the root offset would still produce the same values.

Mock getBoundingClientRect on the hovered item and on its .unit-display-root ancestor, using nonzero values. Then assert that tooltip.style.left and tooltip.style.top equal the values the formula produces from those rectangles.

…r, when radial menu is open (otherwise only radial menu would be closed, but the clicked build button would still not be selected and the attack ratio not be changed so a user had to click again which is confusing especially for a build button. Player didn't know they had to click build button again, tapped on the map and the Radial Menu appeared again instead of the expected build preview).

Also address a possible edge case when myPlayer.actions in MainRadialMenu is slow to load, player taps eg. build button > CloseViewEvent has just made RadialMenu hide itself, build preview is expected > but after myPlayer.actions updatePlayerActions is called > calls showRadialMenu > Radial Menu re-appears instead of the build preview.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Emit the final placement move when a candidate drag releases past the threshold.

A touch that starts on the preview enters candidate. If its last pointermove stays under DRAG_THRESHOLD_PX but pointerup lands beyond it, no move is emitted and the preview stays on its old tile. The active path emits this final move, so candidate should use the same rule.

tests/client/RadialMenu.test.ts: 1

53-57: Trivial · Maintainability & Code Quality · Quick win

Assert the forwarded-click marker in the forwarding test.

The test at lines 55-57 checks only the click count and the coordinates. Removing the FORWARDED_CLICK marker from forwardClickToLayerBelow still passes it. The ControlPanel slider test sets the marker by hand, so no test fails when the producer stops setting it. The slider then ignores overlay taps, because handleRatioSliderClick returns early without the marker.

Suggested test change
 import { RadialMenu } from "../../src/client/hud/layers/RadialMenu";
+import { isForwardedClick } from "../../src/client/InputHandler";
     expect(clicks[0].clientY).toBe(20);
+    expect(isForwardedClick(clicks[0])).toBe(true);

Add a positive opening assertion to this test.

If the desktop @click binding (ControlPanel.ts:647) breaks, both tests still pass. Add a test that targets .hidden.lg\\:block input[type="range"] and asserts the forwarded-tap update.

A regression that drops the result after the move would still pass. Add a case that resolves the pending request after the move and asserts builds contains tile 101.

Assert that the deferred invalid confirmation emits no build.

The test "touch confirmation on an unbuildable structure cancels the selection" resolves a City query with canBuild: false. It checks the cleared ghost and the empty queue, but it never reads builds. A regression that emits BuildUnitIntentEvent on this path would still pass. The helper already returns builds, so the fix is one assertion plus destructuring the array:

Suggested fix
-    const { controller, requests, uiState } = makeDeferredBuildablesController(
-      UnitType.City,
-    );
+    const { controller, builds, requests, uiState } =

Add a two-pointer release test for ghost placement.

…ntented when attack % slider or build button is tapped/clicked as when the radial menu does not 'overlap' with the control panel.

Add edge fade to the build bar on very narrow screens, as a cue to show there's more to swipe to. Still no scrollbar.

Instead of a counter, use a per-request token in MainRadialMenu to see what menu request a pending action belongs to.

Tests added and improved.

Dispatch the menu-item click on a real rendered path.

The test attaches stopPropagation() to its synthetic path, so it does not exercise the real RadialMenu item handler. Removing the production guard would not change the test result. Use a rendered menu item to protect this propagation behavior.

Add long press to show tooltip above build button on touchscreen; it until now only showed on hover with mouse. Shows as long as you press, and as failsafe removes after touch cancel when no touch end arrives. Corrected tooltip z-index so it is displayed on top of events (which are shown above control panel on mobile portrait mode). Tooltip is shown within viewport for smaller screens.

…nly until long press ends.

Address claude and rabbit feedback. Eg, with disabled units, keep old behaviour of centering the build buttons. Unbuildable touch taps now clear the active structure highlight. Touch build selections signal placement mode through InputHandler.ts and BuildPreviewController.ts, preventing the initial ghost from "appearing" at screen (0,0). Updated UnitDisplay.test.ts?s mock config with gameConfig() so CI should no longer fail (tests already ran ok locally).
