From 29a1e8dfda49c96ff3f4306c2ad53ba01922306f Mon Sep 17 00:00:00 2001 From: Ivan Batsulin Date: Wed, 22 Apr 2026 00:06:07 +0300 Subject: [PATCH] feat: multi-warship selection with Shift+drag box (#3677) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Resolves #3666 ## Description: Adds RTS-style box selection for warships. Hold Shift and drag (desktop) or long-press and drag (touch/mobile) to draw a selection rectangle — all player-owned warships inside get selected at once. A subsequent click/tap on water sends them all to that location. - `SelectionBoxLayer` — pixel-dashed rectangle in world-space, player territory color; shared between desktop and touch - `UILayer` — same pulsing selection outline on each box-selected warship; clears correctly when switching between single/multi selection - `UnitLayer` — finds warships in screen rect, filters inactive ships before sending; touch support included - `InputHandler` — Shift+drag and touch long-press+drag both emit selection box events; cursor becomes crosshair on Shift; discards active ghost structure on Shift press; configurable via `shiftKey` keybind - `Transport` — single atomic `move_multiple_warships` intent (no split on socket drop) - `Schemas` + `ExecutionManager` + `MoveMultipleWarshipsExecution` — server fans out atomic intent into individual `MoveWarshipExecution` per ship - `DynamicUILayer` — `MoveIndicatorUI` chevron animation on target tile for both single and multi move - `UnitDisplay` — warship tooltip Shift hint via `translateText` - `HelpModal` — new hotkey row: Shift + drag → select multiple warships ## Please complete the following: - [x] I have added screenshots for all UI updates - [x] I process any text displayed to the user through translateText() and I've added it to the en.json file - [x] I have added relevant tests to the test directory - [x] I confirm I have thoroughly tested these changes and take full responsibility for any bugs introduced ## UI update ### Mouse + Keyboard https://github.com/user-attachments/assets/3f35ab5e-1f3c-4c5d-bc4f-aabccf64dc60 ### Touch https://github.com/user-attachments/assets/0d6aec3f-44fa-4fee-b5c6-b267b9b14d79 ## ## Please put your Discord username so you can be contacted if a bug or regression is found: fghjk_60845 --- resources/lang/en.json | 4 + src/client/HelpModal.ts | 22 ++ src/client/InputHandler.ts | 227 ++++++++++++++- src/client/Transport.ts | 4 +- src/client/graphics/layers/UILayer.ts | 316 +++++++++++++++++---- src/client/graphics/layers/UnitDisplay.ts | 9 +- src/client/graphics/layers/UnitLayer.ts | 100 ++++++- src/core/Schemas.ts | 2 +- src/core/execution/ExecutionManager.ts | 2 +- src/core/execution/MoveWarshipExecution.ts | 35 ++- src/core/game/UserSettings.ts | 1 + tests/InputHandler.test.ts | 187 ++++++++++++ tests/Warship.test.ts | 12 +- tests/WarshipMultiSelection.test.ts | 144 ++++++++++ 14 files changed, 971 insertions(+), 94 deletions(-) create mode 100644 tests/WarshipMultiSelection.test.ts diff --git a/resources/lang/en.json b/resources/lang/en.json index 16a3206a4..bd2c2b74a 100644 --- a/resources/lang/en.json +++ b/resources/lang/en.json @@ -106,6 +106,9 @@ "action_ratio_change": "Decrease/Increase attack ratio", "action_reset_gfx": "Reset graphics", "action_auto_upgrade": "Auto-upgrade nearest building", + "action_warship_multiselect": "Select multiple warships (drag to draw selection box)", + "action_warship_selectall": "Select all your warships", + "drag": "drag", "ui_section": "Game UI", "ui_leaderboard": "Leaderboard", "ui_your_team": "Your team:", @@ -761,6 +764,7 @@ "city": "Increases max population", "factory": "Creates railroads and spawns trains" }, + "warship_shift_hint": "Hold Shift and drag to select multiple warships at once", "not_enough_money": "Not enough money" }, "win_modal": { diff --git a/src/client/HelpModal.ts b/src/client/HelpModal.ts index 261a0b0d7..c58a588fd 100644 --- a/src/client/HelpModal.ts +++ b/src/client/HelpModal.ts @@ -434,6 +434,28 @@ export class HelpModal extends BaseModal { ${translateText("help_modal.action_auto_upgrade")} + + +
