Before opening a PR: discuss new features on Discord first, and file bugs or small improvements as issues. You must be assigned to an approved issue — unsolicited PRs will be auto-closed.

Add approved & assigned issue number here:

Resolves #3164

Description:

Adds troop and gold donation keybinds to the game for faster donations to avoid having to use the radial menu.

Below is a table showing which new keybinds do what:

Quantity Gold Troops
Attack ratio % Shift + I key Shift + O key
10% (or some other number) Shift + K key Shift + L key

The 10% number is default but can be changed in settings.

UI changes:

Below are the screenshots of the UI/visible changes:

Donation keybind fixed amount:

Donation keybind fixed amount

Donation keybinds:

Donation keybinds

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

Please put your Discord username so you can be contacted if a bug or regression is found:

Walkthrough

Adds four donation keybinds for gold and troops. Supports attack-ratio and fixed-percentage donations. Adds configurable donation amounts, input handling, game intents, settings controls, help text, localization, and tests.

Changes

Donation hotkeys

Layer / File(s) Summary
Donation settings and defaults
src/core/game/UserSettings.ts, src/client/UserSettingModal.ts, tests/UserSettings.test.ts
Adds four default keybinds, validates donation amounts from 1% to 100%, exposes a selector from 1% to 50%, and tests persistence, fallback, clamping, and defaults.
Donation input and execution
src/client/InputHandler.ts, src/client/ClientGameRunner.ts, tests/InputHandler.test.ts
Adds typed donation events and keybind handlers. Resolves the cursor recipient, checks permissions, calculates a positive donation, and emits the matching donation intent.
Donation help and localization
src/client/HelpModal.ts, resources/lang/en.json
Adds four donation hotkey rows and localized descriptions. Fixed-amount descriptions include the configured percentage.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to c05af

The new donation shortcuts work through settings, input handling, and donation intents, but help text will show an untranslated “Shift+” prefix in non-English locales. Localize this label before merge.

Shifted keys awake,
Gold and troops cross the field,
Ratios guide the gift.
Fixed amounts stand ready,
Settings keep the measure,
Hotkeys ring bright.

myPlayer.actions callback to convert the ratio into an integer percentage before
computing both gold and troop amounts, avoiding floating-point multiplication
before flooring. Preserve gold precision by performing the gold calculation
entirely with bigint values rather than converting gold through Number; keep the
existing positive-amount checks and event emissions.

In `@src/client/UserSettingModal.ts`:
- Around line 999-1007: Update the percentage option labels in the
UserSettingModal options configuration to use translateText() with an amount
parameter instead of raw user-visible strings, and add the corresponding English
resource entry in resources/lang/en.json. Do not modify non-English translation
files.

In `@src/core/game/UserSettings.ts`:
- Around line 720-733: Update donationKeybindAmount and setDonationKeybindAmount
to use integer-string storage and parsing instead of getFloat and Math.round.
Preserve validation and clamping to the inclusive 1–100 range, with invalid
values returning 10, and remove all floating-point processing from these
methods.

In `@tests/InputHandler.test.ts`:
- Around line 613-648: Replace the eventBus.emit spies in the gold and troop
donation tests with direct core-simulation setup and keybind execution. Assert
the resulting donation intent or resource transfer for both attack-ratio and
fixed-amount inputs, using the existing simulation APIs and preserving coverage
of both keyboard shortcuts.

🤖 Claude Code Review

Verdict: Approve with one minor fix suggested. Findings: 1 low-severity, 0 medium/high.

src/client/HelpModal.ts

[Low] Help modal renders raw key codes for the new Shift-combo keybinds instead of formatted labels (src/client/HelpModal.ts:47-51, new rows at ~390-430)

getKeyLabel has no handling for a "Shift+" prefix:

if (specialLabels[code]) return specialLabels[code];
if (code.startsWith("Key") && code.length === 4) return code.slice(3);
if (code.startsWith("Digit")) return code.slice(5);
if (code.startsWith("Numpad")) return `Num ${code.slice(6)}`;
return code;   // "Shift+KeyI" falls through here

This PR's four new default keybinds (Shift+KeyI, Shift+KeyO, Shift+KeyK, Shift+KeyL, defined in src/core/game/UserSettings.ts:37-40) are the first Shift-combo binds ever surfaced in the Help modal's keybind table (the one pre-existing Shift default, retaliateAttack: "Shift+KeyR", isn't rendered there). Since UserSettings.keybinds() passes the raw string through unnormalized, all four new rows will display the literal text Shift+KeyI, Shift+KeyO, Shift+KeyK, Shift+KeyL instead of a clean label like Shift+I.

For comparison, the Settings modal already handles this correctly via formatKeyForDisplay in src/client/Utils.ts:358-361:

if (value.startsWith("Shift+")) {
  return "Shift+" + formatKeyForDisplay(value.slice(6));
}

Suggested fix: Add the same Shift+ recursion to getKeyLabel in HelpModal.ts, or have it delegate to formatKeyForDisplay instead of maintaining a separate label map.

This is purely a display/cosmetic issue — the keybinds themselves function correctly (InputHandler handles the combo fine), and the underlying donation logic, permission checks, BigInt/percentage math, and i18n usage all checked out clean across two independent bug-focused reviews and two independent CLAUDE.md compliance reviews.

🤖 Claude Code Review

Verdict: No issues found. Findings: 0 critical, 0 high, 0 medium, 0 low.

Reviewed for CLAUDE.md compliance (i18n via translateText()/en.json, src/core determinism and test-coverage requirements, testing patterns) and for bugs/security issues in the diff (keybind collision checks, BigInt/rounding math in the donation calculation, null-safety around cursor/tile/player resolution, regex validation and clamping for the new donationKeybindAmount setting). No unambiguous violations or high-confidence bugs surfaced.

No issues found. Checked for bugs and CLAUDE.md compliance.

Translate the Shift+ prefix.

Line 26 renders Shift+ directly. This bypasses localization for non-English locales. Add an English resource entry and pass the prefix through translateText(), with the key label as an interpolation.

As per coding guidelines, all user-visible text in src/client/**/*.{ts,tsx} must go through translateText() and have a corresponding entry in resources/lang/en.json.
