Migration notes: godot-input-handling

Incremental upgrade for topics this skill covers. Apply one hop, stabilize/test, then next. Never skip hops.

If the project is < 4.0, follow godot-version-migration era bridges (legacy → 3→4) until 4.0, then these hops. Official 3→4: Upgrading from Godot 3 to Godot 4.

3.x → 4.0

Official: Upgrading from Godot 3 to Godot 4

• Prefer Signal.connect(callable) over string connect (converter may leave strings).
• InputEventWithModifiers: alt/shift/… → alt_pressed/shift_pressed/…
• InputEventMouseButton.doubleclick → double_click.
• Screen/window queries moved OS → DisplayServer (screen_get_size, etc.).

4.0 → 4.1

Official: Upgrading to Godot 4.1

• Viewports with physics picking enabled auto-mark InputEvents handled — adjust _unhandled_input gameplay handlers that expected pick events to bubble.
• SubViewportContainer.mouse_filter behavior changed — mouse events may pass through differently; verify UI-over-world click routing.

4.1 → 4.2

Official: Upgrading to Godot 4.2

No skill-relevant breaking changes for this hop.

4.2 → 4.3

Official: Upgrading to Godot 4.3

4.3 → 4.4

Official: Upgrading to Godot 4.4

• Android motion sensors disabled by default — enable Project Settings → Input Devices → Sensors before tilt/virtual-analog input drives gameplay actions.

4.4 → 4.5

Official: Upgrading to Godot 4.5

No skill-relevant breaking changes for this hop.

4.5 → 4.6

Official: Upgrading to Godot 4.6

4.6 → 4.7

Official: Upgrading to Godot 4.7

• InputEvent.DEVICE_ID_MOUSE / InputEvent.DEVICE_ID_KEYBOARD replace magic -1 / 0 for mouse and keyboard — update device routing in glyph prompts and split-screen controllers.
• NEVER compare event.device == 0 for mouse/keyboard — joypads may legitimately use device ID 0.
• New projects default stretch mode canvas_items + aspect expand (was disabled/keep) — retest touch/action coordinate mapping on resizable windows.
