feat(input): 三指直接平移/缩放（无需旧"平移与缩放"开关） by cjcxj · Pull Request #549 · qiin2333/moonlight-vplus

cjcxj · 2026-08-28T01:19:50Z

功能

新增三指直接平移/缩放，第三指按下即接管画面操作，全部抬起后恢复游戏输入；一指和两指沿用原有输入方式。

返回菜单新增“三指平移/缩放”开关，默认开启并持久化；点整行和点开关都能切换并立即刷新。
关闭功能时保留 master 原有触摸路由和键盘快捷手势。
无明显位移、300ms 内完成的三指快击仍可唤出键盘；增强触摸遵循原有唤键盘指数量设置。
菜单旧“平移与缩放”入口由新开关替代，原按键映射入口保留。
补齐英文、简体中文和繁体中文。

本轮同步与修复

已同步最新 master，并修复三条审查意见：行点击开关显示不刷新、三指手势抢占 DS5 触控板，以及增强触摸重复发送 DOWN。

自审补充修复：

接管时取消之前的触摸/鼠标状态，增强触摸发送 CANCEL_ALL 后清理坐标与路由状态。
DS5 触控板、手动平移/缩放和虚拟控制器编辑模式不启动新手势。
接管后持续消费到 UP/CANCEL，中途改开关不把尾部事件发给主机；释放输入捕获时取消本地手势。
按 pointerId 检查尾部移动、历史采样与抬起坐标；取消标记、额外或替换触点不会误触键盘。
为本地手势检测器补齐按下序列，合成事件不发送给主机。
PanZoomHandler 用结束回调替代对 Game 的直接依赖，保留 PiP 行为，便于测试真实检测器。

验证

:app:testNonRootDebugUnitTest：567 项通过。
模拟器仪器测试：13 项通过，覆盖三指接管、取消、设置变化、pointerId 顺序、快击识别、真实 Android 缩放/平移与光标联动，以及菜单行/开关控件。
:app:lintNonRootDebug、:app:assembleNonRootDebug、:app:assembleNonRootDebugAndroidTest、git diff --check：通过。
Local Sunshine WebUI、串流协议和 USB 按键路由未修改。

人工回归

经典、触控板、增强触摸分别测试三指平移/缩放、快击键盘和重新开始一指操作。
关闭功能后确认原有输入不变；开启后部分抬指、取消触摸或打开菜单不留下持续输入。
DS5 触控板模式不被三指功能接管。
行点击与开关点击立即更新，重启后状态保持。

真实 DS5 与主机端收包尚未进行本轮硬件验收，不能以本地手势测试替代。

Summary by CodeRabbit

New Features
- Added three-finger pan and zoom gestures for supported touch controls.
- Added a game menu toggle to enable or disable the gesture, with the setting saved and enabled by default.
- Three-finger taps can toggle the keyboard when applicable.
- Gestures now end cleanly when touch input is released or canceled.
Localization
- Updated English, Simplified Chinese, and Traditional Chinese labels and notifications to identify the three-finger gesture.

- 第三指按下即进入平移/缩放，1/2 指保持游戏输入，无需旧开关 - 进入时取消已下发的 1/2 指触摸/鼠标并发送 LI_TOUCH_EVENT_CANCEL_ALL，防粘键 - 游戏菜单新增持久化开关“三指平移/缩放”（checkbox_three_finger_pan_zoom，默认开） - 关闭开关时回退旧行为：三指快击唤键盘 - 移除游戏菜单旧“平移与缩放”入口（按键映射 SPECIAL_KEY_PAN_ZOOM_MODE 保留）

1. GameMenu：三指平移/缩放开关的 InlineControl.Toggle 缺少 toggleAction，点击复选框时 handleInlineToggle 直接 return 不生效；切换逻辑抽为局部 Runnable 并同时挂到 runnable（行点击）与 toggleAction（复选框点击），与王冠开关的并存模式一致。 2. TouchInputHandler：三指模式尾巴段（部分手指抬起、pointerCount 降到 2/1）不再检测移动，抬一指后继续双指平移仍可能被当作"快击"误触键盘切换。进入模式时记录原始 pointerId，移动检测按 ID 追踪剩余手指，任一剩余手指位移超阈值即标记为有意图手势。

📝 Walkthrough

Walkthrough

Adds a persistent three-finger pan/zoom setting, a dedicated pointer-aware gesture handler, touch-state cancellation, pan/zoom routing, updated menu resources, and enhanced-touch event handling.

Changes

Three-finger pan/zoom

Layer / File(s)	Summary
Three-finger gesture engine `app/src/main/java/com/limelight/binding/input/touch/ThreeFingerPanZoomGesture.kt`, `app/src/androidTest/java/com/limelight/binding/input/touch/ThreeFingerPanZoomGestureTest.kt`	Adds gesture ownership, pointer-ID tracking, synthetic pan/zoom initialization, movement detection, keyboard-tap handling, cancellation, and instrumentation coverage.
Touch input integration `app/src/main/java/com/limelight/TouchInputHandler.kt`, `app/src/main/java/com/limelight/Game.kt`	Enables the gesture only in compatible modes, preserves DS5 and enhanced-touch precedence, cancels host touch state, routes pan/zoom events, and cancels the gesture when input grab is released.
Configuration, menu, and pan/zoom wiring `app/src/main/java/com/limelight/preferences/PreferenceConfiguration.kt`, `app/src/main/java/com/limelight/gamemenu/`, `app/src/main/java/com/limelight/utils/PanZoomHandler.kt`, `app/src/main/res/values/strings.xml`, `app/src/test/java/com/limelight/gamemenu/ThreeFingerPanZoomOptionTest.kt`, `app/src/androidTest/java/com/limelight/gamemenu/ThreeFingerPanZoomMenuTest.kt`	Adds the enabled-by-default preference, menu toggle, persistence, localized labels and toasts, the PanZoomHandler scale-end callback, and menu tests.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 4d7cb

The three-finger gesture, menu toggle, persistence, cancellation, and pan/zoom wiring are ready to merge.

In `@app/src/main/java/com/limelight/gamemenu/GameMenu.kt`:
- Around line 2159-2184: Update the threeFingerPanZoomToggle MenuOption to use
GameMenuOptionPresentation.COMPATIBLE_ACTION, matching
toggleLocalCursorRendering(), so handleComposeOptionClick refreshes the switch
after row taps while preserving the shared runnable and toggleAction behavior.

In `@app/src/main/java/com/limelight/TouchInputHandler.kt`:
- Around line 468-476: Preserve DS5 touchpad handling in the three-finger
interception around `enableThreeFingerPanZoom`: when `screenDs5Touchpad` is
enabled, route events through `trySendScreenDs5TouchpadEvent` before
`game.panZoomHandler.handleTouchEvent(event)` and its early return, or exclude
DS5 touchpad mode from this branch.
- Around line 577-580: Update the touch-event handling around trySendTouchEvent
so MotionEvent.ACTION_DOWN is not passed to trySendTouchEvent a second time when
the first attempt returns false. Reuse the initial result or exclude ACTION_DOWN
from this fallback block while preserving retries for other event actions.
