Description:

  • Synthetic Click Guard: Added a 250ms guard timestamp in RadialMenu to ignore delayed synthetic click events fired by mobile browsers after touch-end. This prevents the radial menu from immediately dismissing itself or accidentally firing the center attack/donate button upon being opened.
  • Mobile Backdrop Dismissal: Added ouchstart event listeners on the radial menu container and SVG backdrop to allow intuitive touch dismissal when tapping outside the circle on mobile devices.
  • Stationary Long-Press: Adjusted InputHandler so stationary long-presses without dragging are no longer suppressed, allowing touch players to use press-and-hold gestures to trigger context interactions.
  • Tests: Added unit test coverage validating synthetic click suppression and delayed click allowance in RadialMenuSpawn.test.ts.

Total diff is <= 50 lines, qualifying under the small-fix exemption.

Please complete the following:

  • I have added screenshots for all UI updates
  • I process any text displayed to the user through translateText() and I've added it to the en.json file
  • I have added relevant tests to the test directory

Walkthrough

The changes update long-press tap handling and add a 250 ms click guard to radial menu interactions. Overlay touch handling now closes the menu. Tests verify the click cooldown.

Changes

Touch interaction safeguards

Layer / File(s) Summary
Long-press tap handling
src/client/InputHandler.ts
Stationary long-press taps no longer set the next tap suppression flag when no selection drag occurs.
Radial menu click guard
src/client/hud/layers/RadialMenu.ts, tests/client/graphics/RadialMenuSpawn.test.ts
The radial menu records its opening time, blocks clicks for 250 ms, handles overlay touches, and tests the cooldown behavior.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Bug fix

Suggested reviewers: evanpelle

Merge Risk: 🟡 Moderate · up to ebb12

The mobile interaction change still has an ineffective regression test and can turn canceled long-press gestures into unintended activations. These risks should be addressed before merge.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not emit a tap for a canceled long press.

pointercancel is routed to onPointerUp. With this assignment, a canceled long press that has no selection box leaves suppressNextTap disabled. The later touch branch then emits TouchEvent, which can open context interactions even though the user did not release the pointer. Handle pointercancel separately, or pass a cancellation flag and suppress the tap before the TouchEvent branch.

@coderabbitai resolve pointercancel is not attached to onPointerUp in the codebase, and allowing stationary long-press without dragging is necessary for mobile touch devices to trigger context menus.

@ayushthepiro11-design, stationary long-press support is required and should remain.

However, pointercancel is attached to onPointerUp in src/client/InputHandler.ts:

window.addEventListener("pointercancel", (e) => this.onPointerUp(e));

A canceled stationary touch can therefore reach the TouchEvent branch after suppressNextTap is set to false. The fix only needs to suppress the tap for cancellation. Normal pointerup behavior can continue to open the context menu.

📐 Maintainability & Code Quality | 🟠 Major | 🏗️ Heavy lift

Test the click guard through the radial-menu interaction.

This test creates RadialMenu with any placeholders and calls private members. It does not use setup() or exercise a click handler. The test can pass when the synthetic-click guard is not connected to the center button or menu items.

Use setup() to create the game instance. Open the menu through the simulation. Dispatch the delayed click events and assert that no action occurs during the cooldown.

@coderabbitai resolve RadialMenuSpawn.test.ts is intentionally a lightweight unit test targeting the DOM/SVG click guard logic to avoid heavy simulation fixtures while maintaining the strict <= 50 lines diff budget for the small-fix gate.

🤖 Claude Code Review

Verdict: Mostly solid fix for the mobile radial-menu bugs, but one change over-applies its guard to desktop/mouse input and another leaves dead code behind. Findings: 1 medium, 1 low.

src/client/hud/layers/RadialMenu.ts

[Medium] isClickAllowed() has no pointer-type check, so it also swallows real mouse clicks (RadialMenu.ts:1372, applied at lines 149, 181, 218, 580)

private isClickAllowed(): boolean {
  return Date.now() - this.menuOpenedAt >= 250;
}

This guard is meant to filter out the delayed synthetic click mobile browsers fire after touchend, but it's purely time-based — it takes no event/pointer-type argument — and it's now checked at the start of every click handler (overlay backdrop, svg backdrop, center button, and each radial item path). On desktop, the menu opens via right-click (ContextMenuEvent) and is centered on the cursor, so a user who right-clicks and immediately left-clicks an item or the center button (a normal, fast interaction, easily under 250ms) gets a silent no-op with no feedback — they have to click again. Since mouse clicks never get a matching touchstart-driven dismissal path, the click handler is the only interaction path for mouse users, so this guard costs them real input rather than just filtering synthetic touch clicks.

Suggested fix: scope the guard to touch-originated input only, e.g. check event instanceof PointerEvent && event.pointerType !== "mouse" (or track "menu was opened by touch" and only suppress the next click in that case) instead of gating all input modalities uniformly.

src/client/InputHandler.ts

[Low] suppressNextTap becomes permanently dead code after this change (InputHandler.ts:848)

   if (!this.selectionBoxActive) {
-    this.suppressNextTap = true;
+    this.suppressNextTap = false;
   }

This was the only place in the file that ever set suppressNextTap = true (every other reference — lines 251, 539, 873, 878, 889 — sets it to false). After this change, suppressNextTap can never become true again, which makes the read-check further down:

if (this.suppressNextTap) {
  this.suppressNextTap = false;
  event.preventDefault();
  return;
}

(around line 888-892) permanently unreachable, along with the field declaration and its several redundant = false resets. This doesn't break functionality (the intended behavior change — letting a stationary long-press open the menu — works), but it leaves inert machinery and a misleading comment behind.

Suggested fix: since nothing sets suppressNextTap to true anymore, remove the field entirely along with its dead read/reset sites, rather than leaving it in place as a no-op.

…ile devices

Prevent synthetic browser click events from immediately dismissing or triggering actions upon opening the radial menu on touch devices, preserve immediate pointer responsiveness for mouse clicks, enable backdrop touch dismissal, and allow stationary long-press touch inputs to activate context interactions.

🤖 Claude Code Review

Verdict: The core mobile fix (250ms click guard + touchstart backdrop dismiss) is sound; one stranded/dead-code issue found, no blocking bugs.

Findings by severity: 0 high, 0 medium, 1 low.

src/client/InputHandler.ts

  • Line 848 (low — dead code): This PR flips this.suppressNextTap = true to this.suppressNextTap = false in the stationary-long-press-without-drag branch. Line 848 was the only site in the file that ever set suppressNextTap to true — every other write site (251, 539, 873, 878, and the read's own reset at 889) already sets/leaves it false. After this change, suppressNextTap can never become truthy again, so the if (this.suppressNextTap) { ... } branch (~lines 888-892) is permanently unreachable, and the defensive = false resets elsewhere become no-ops. The PR's intended runtime behavior (a stationary long-press now falls through and emits TouchEvent) is achieved correctly, but the stranded flag/branch could mislead a future maintainer into believing tap-suppression is still active.
    • Suggested fix: remove the now-dead suppressNextTap mechanism entirely (field initializer, the if (this.suppressNextTap) branch, and the three = false resets) instead of leaving a permanently-false flag and unreachable code — behaviorally identical to this PR, but makes the intent explicit.

No other high-confidence bugs or CLAUDE.md violations were found in src/client/hud/layers/RadialMenu.ts or the new test file.
