Description

Adds physical controller stick tuning through a new settings page in the in-game quick menu.

  • Separate deadzone and sensitivity controls for each stick
  • 0–100% deadzone and 0.10×–3.00× sensitivity ranges
  • Axial, circular, and hybrid deadzone modes
  • Unrestricted, 4-way, and 8-way direction modes

Most of the original implementation was created by @phobos665. I picked up his work and completed the integration, UI and fixes. Huge thanks to him for building the foundation of this feature. :)

Summary by cubic

Adds per-stick deadzone, sensitivity, direction snapping, and deadzone shape tuning for physical controllers, replacing the fixed stick deadzone and configurable from a new settings dialog in the in-game quick menu.

Tuning options

  • Deadzone ranges 0–100% and sensitivity 0.10×–3.00× per stick.
  • Supports axial, circular, and hybrid deadzone shapes; unrestricted, 4-way, and 8-way direction snapping.
  • Tuning applies to gameplay, radial menus, and controller profiles; players 2–4 share the active profile's tuning.
  • Profiles carry tuning through export and import, and profiles without custom tuning keep legacy behavior.
  • Settings save is atomic with rollback, surfaces failures to the user, and preserves sub-pixel mouse movement.

Written for commit 0a3713c. Summary will update on new commits.

📝 Walkthrough

Walkthrough

The change adds configurable physical-controller stick tuning for deadzones, sensitivity, deadzone shapes, and direction modes. It adds a settings dialog, profile persistence and validation, runtime input processing, localized strings, and tests.

Changes

Physical controller stick tuning

Layer / File(s) Summary
Tuning data and profile persistence
app/src/main/java/com/winlator/inputcontrols/ControlsProfile.java, app/src/main/java/com/winlator/inputcontrols/InputControlsManager.java, app/src/main/java/com/winlator/inputcontrols/StickVectorProcessor.java, app/src/main/java/app/gamenative/inputcontrols/ControlProfileService.kt, app/src/test/java/com/winlator/inputcontrols/PhysicalControllerStickTuningTest.kt, app/src/test/java/app/gamenative/inputcontrols/ControlProfileServiceTest.kt
Adds per-stick tuning fields, defaults, JSON loading and conditional serialization, vector transforms and direction snapping, and profile-section copying and validation. Tests cover tuning calculations, persistence, and profile operations.
Runtime stick processing and input activation
app/src/main/java/com/winlator/inputcontrols/ExternalController.java, app/src/main/java/com/winlator/widget/InputControlsView.java, app/src/main/java/app/gamenative/ui/screen/xserver/PhysicalControllerHandler.kt, app/src/test/java/app/gamenative/ui/screen/xserver/PhysicalControllerHandlerTest.kt
Applies configured tuning and direction snapping to controller input. Tuned axes use nonzero input activation, and mouse movement retains fractional deltas. The handler synchronizes timer updates with mouse-movement resets. Tests cover tuned and legacy input behavior.
Settings entry point and dialog
app/src/main/java/app/gamenative/ui/component/QuickMenu.kt, app/src/main/java/app/gamenative/ui/screen/xserver/XServerScreen.kt, app/src/main/java/app/gamenative/ui/component/dialog/PhysicalControllerConfigSection.kt, app/src/main/res/values*/strings.xml
Adds a quick-menu settings action and a dialog for editing both sticks. Save and dismiss behavior is wired through XServerScreen. Localized resources provide setting labels and descriptions.

Merge Risk: 🔵 Low · up to 3a4db

Stick tuning only becomes inconsistent if saving the settings fails. In that case the unsaved values stay in the in-memory profile and could be written out by a later save. Restore the previous values on a failed save, or apply them only after the save succeeds. The rest of the change looks safe to merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 3a4db

The change is bounded to local controller configuration and game input. Imported settings have validation controls, and normal profile changes release active input. However, a failed settings save can leave in-memory activation behavior inconsistent with the active tuning configuration. Broader runtime coverage remains incomplete.

Retained concerns

  • Low · reliability · inferred: The new save transition updates the shared profile before persistence succeeds but publishes the runtime tuning snapshot only after success. If saving fails, an initially untuned profile can retain its newly configured flag while the producer still uses legacy tuning. Consumers then treat nonzero stick values as active without the matching configured deadzone. Closing the dialog does not restore the previous profile state, allowing failed configuration changes to affect mapped-input activation within the session.
Security review details

Security Blast Radius

  • inferred — The evidenced exposure is local input behavior in the active game session. Tuning is shared across controller instances, including additional-player controllers, rather than isolated to one device. Controller axes can reach mapped gamepad, key, and pointer outcomes; the inspected changes do not establish broader service or privilege authority.

Trust Boundaries and Controls

  • observed — Externally supplied profile JSON crosses a validation boundary before import preview: input is limited to 2 MB, sections are checked, physical-controller payloads require controller data or tuning keys, and supplied tuning numbers and modes are validated. This constrains the new tuning-only import path.
  • observed — Shared tuning is published as one immutable volatile configuration. Cleanup clears it only when the requesting owner still owns the active configuration, preventing an older owner from clearing a newer owner's tuning.

Resilience and Maintainability Implications

  • inferred — The fallback InputControlsView path has release and timer-lifecycle limitations that largely predate this PR. Normal XServerScreen routing first uses PhysicalControllerHandler, which consumes recognized controller events and implements explicit cleanup. Consequently, the fallback observations do not establish an introduced or materially worsened normal-path security concern; detached-view reuse and exceptional fallback exposure remain incompletely covered.
