godot-adapt-mobile-to-desktop

NEVER Do

• NEVER keep touch-only controls — Add mouse/keyboard alternatives. Touch controls on desktop feel awkward and limit precision.
• NEVER lock to mobile resolution — Desktop can handle 1920x1080+ and higher frame rates. Upscale UI, increase render distance.
• NEVER hide graphics settings — Desktop players expect quality options (resolution, VSync, shadows, anti-aliasing).
• NEVER use mobile-sized UI — Touch targets (44pt) are too large for mouse. Reduce button/text size by 30-50%.
• NEVER forget window management — Players expect fullscreen, borderless, maximize, and multi-monitor support.

Available Scripts

MANDATORY: Read the appropriate script before implementing the corresponding pattern.

[desktopinputadapter.gd](scripts/desktopinputadapter.gd)

MANDATORY first read for input remap — Bridges mobile actions to keyboard/mouse without rewriting gameplay. Emits mouselookbridgerequested when FPS capture is needed — pair with mousecapture_look.

[hoverbridge.gd](scripts/hoverbridge.gd)

MANDATORY when UI needs hover — Restores desktop hover/focus affordances mobile never had. Prefer this over ad-hoc mouse_entered dumps.

[mousecapturelook.gd](scripts/mousecapturelook.gd)

Captured look via InputEventMouseMotion.relative — use for FPS/orbit when adapter alone is not enough.

[dynamicwindowmanager.gd](scripts/dynamicwindowmanager.gd)

MANDATORY — Windowed / exclusive fullscreen / borderless via DisplayServer.

[keybindingremapper.gd](scripts/keybindingremapper.gd)

Runtime InputMap remap + ConfigFile persistence.

[cursorstatemanager.gd](scripts/cursorstatemanager.gd)

Hardware cursor show/hide/combat vs menu states.

[uncappedframerate.gd](scripts/uncappedframerate.gd)

VSync / Engine.max_fps unlock for 144Hz+.

[resolutiondropdown.gd](scripts/resolutiondropdown.gd)

Native resolution OptionButton from DisplayServer.screengetsize.

[desktopuiscaler.gd](scripts/desktopuiscaler.gd)

MANDATORY — Shrink thumb-sized mobile Controls for mouse density.

[scrollwheelzoom.gd](scripts/scrollwheelzoom.gd)

Mouse-wheel zoom replacing pinch.

[quitconfirmation.gd](scripts/quitconfirmation.gd)

MANDATORY — setautoaccept_quit(false) + save prompt on WM close.

[multimonitorhandling.gd](scripts/multimonitorhandling.gd)

Launch/place window on the screen under the cursor.

Decision Tree — Input Script Picks

When desktopinputadapter emits mouselookbridgerequested, attach or enable [mousecapturelook.gd](scripts/mousecapture_look.gd) on the player/camera rig — do not stop after InputMap injection.

Port Procedure (ordered)

1. MANDATORY desktopinputadapter (+ hover_bridge for UI) so every touch action has a precision equivalent.
2. desktopuiscaler + expanded layouts (hotbar/chat/minimap) — godot-ui-containers for structure.
3. dynamicwindowmanager + multimonitorhandling + quit_confirmation.
4. resolutiondropdown + uncappedframerate + graphics quality ladder (persist ConfigFile).
5. Deeper OS integration → godot-platform-desktop.

Platform Services Decision Tree (Steam / Discord)

Deep Recipes

MANDATORY when porting beyond the ordered procedure: read [desktop-port-deep.md](references/desktop-port-deep.md). Do NOT Load it for a first-pass keyboard/mouse remap.

Testing (before ship)

MANDATORY before declaring the port complete: run [desktop-port-testing-checklist.md](references/desktop-port-testing-checklist.md). Do not inline a partial checklist — use the reference file.

Expert Techniques (short)

• Optional lightweight launcher via OS.create_process + user://settings.cfg before main pack.
• Short FPS benchmark → write user://override.cfg quality suggestions.
• Graphics quality ladder (MSAA, shadow atlas, post-FX) and UI density tables live in [desktop-port-deep.md](references/desktop-port-deep.md) — open when port procedure rows are insufficient.

Official Documentation

• Using InputEvent — Event pipeline for replacing InputEventScreenTouch/ScreenDrag with mouse motion, buttons, and keyboard actions on desktop.
• Mouse and input coordinates — Viewport vs canvas transforms so mouse aim and hover hit the same UI/game space as former touch targets.
• Custom mouse cursor — Hardware cursor shapes and hide/show rules for combat vs menus (Input.setcustommouse_cursor).
• Input examples — Practical WASD, mouse-look, and action patterns that map onto mobile virtual-joystick / button actions.
• Handling quit requests — NOTIFICATIONWMCLOSEREQUEST / setautoacceptquit(false) so the OS close button can prompt save instead of silent exit.
• Multiple resolutions — Stretch mode, aspect, and content scale when leaving fixed mobile base resolutions for 1080p–4K and ultrawide.
• DisplayServer — Window modes, VSync, screen count/size/position, and refresh-rate queries behind fullscreen and multi-monitor ports.
• Window — Per-window size, position, and mode APIs used with borderless / exclusive fullscreen toggles.
• InputMap — Runtime remapping of actions to keycodes so PC players can rebind what mobile hard-coded as touch zones.
• Size and anchors — Anchor/offset contracts when shrinking thumb-sized controls for mouse density without breaking layout.
• Using Containers — Box/Grid/Margin layout rules for expanded desktop HUDs (hotbars, chat, minimap) vs compact mobile stacks.
• Feature tags — pc / mobile / OS tags for branching input, UI scale, and graphics quality without separate projects.

Prerequisites

Complements

• godot-platform-desktop — Deeper Windows/macOS/Linux DisplayServer and OS integration once the mobile→desktop control and settings remap is in place.
