Where to start

Three paths, pick one based on where you're coming from:

If you're…	Start here
New to UI Toolkit entirely — never touched it, want orientation first	What is UI Toolkit? — two-minute mental-model intro
Familiar with uGUI, weighing whether to switch	Why UI Toolkit? — side-by-side comparison
Already know UI Toolkit, just want Luna running	Quick Start — 5 minutes to first Play; 10 with the anatomy tour

After Quick Start: First View for writing your own, or jump straight to Components / Views to browse what ships.

What makes Luna different

UI Effects — eight stackable shader effects — outer (shadow & glow), outline, inner overlay, gradient, shine, flash, tile, dissolve — drawn by one uber shader and authored from USS classes, with no source textures to slice.

UI Effects — outer shadow & glow, outline, gradient, and dissolve stacked on a row of buttons

UI Effects — a second set of stacked shader effects on a row of elements

Transition Animations — 53 ready-to-play presets across 7 categories (modals, notifications, attention, loading and more), reusable as ScriptableObjects or built in code with a fluent API.

Transition Animations — the 53-preset gallery

Interaction Juice — press, release and hover reactions as designer-authored profiles you attach to any element, plus juice slots baked into the components: progress bars flash and shake, cooldowns pulse and pop when ready, tabs punch and slide — all wired from UXML, zero code.

Component Library — every built-in control restyled, plus custom components UI Toolkit doesn't ship: linear and radial progress bars with damage indicators and juice slots, tooltips with smart positioning, tab views, cooldown wipes, pie charts, pagination, input prompts and more.

Component library — Luna progress bars in many styles

Tooltip — rich tooltips on a grid of skill icons

Ready-Made Views — the screens every game needs, already built: main menu, settings, save/load, pause, credits, loading, notifications, confirmation popups — plus a full dialogue stack with visual novel view, speech bubbles and tutorial modals.

Settings view — ready-made settings screen with audio, display and input sections

Visual Novel — dual character portraits, speaker label, and dialogue box

Navigation Graph — author screens, modals and tabs as nodes on a graph canvas, then push and pop by string id; back-button semantics come for free.

Navigation Graph — the authoring canvas beside the running game

3D-in-UI Render — a pooled Camera → RenderTexture pipeline drops live 3D models, particle systems and VFX Graph effects straight onto your UI elements.

UI Render — live 3D content rendered inside UI

UI Attractor — coins, gems and XP orbs that burst from a source and fly home to the HUD — pure pooled VisualElements with two-stage scatter → home motion, no cameras or particle systems.

Spotlight — onboarding tours that dim the whole screen except the element you're teaching, glide the highlight from step to step, and gate input until the player follows along.

Text Effects — 12 per-character animations — wave, bounce, shake, rainbow, swing and more — applied with simple rich-text tags inside any label; dialogue text that actually feels alive.

Gamepad-Ready — focus navigation across every view, device-aware input prompts that swap glyphs when the player switches from keyboard to controller, and a layered escape/back stack.

Input Prompts — device-aware button glyphs

Theming — one theme stack drives colors, sizes, fonts and borders across everything; swap palettes at runtime, or generate your own with the Palette Generator.

Theming — change one global theme color and the entire project re-themes

Responsive Scaling — one UI that fits phones and desktops: density-aware breakpoints for layout, automatic per-device scaling for size, and a player UI-Scale slider — no separate mobile and desktop builds.

Responsive — the same screen adapting across phone and desktop widths

GameFull Sample — a complete game shell to learn from or build on: save-aware main menu, reactive HUD, pause menu, inventory with drag-and-drop and a loot loop, save/load, settings with input rebinding — all wired through navigation graphs and real saves.

Also in the box

Drag & Drop — pointer-driven dragging with visual feedback and drop-slot detection
Stagger Entry — list and grid items that cascade in one after another
UI Effect Baking — bake shader effect stacks to plain USS for zero runtime cost
GridView — data-driven grids with pagination; the base the Inventory view builds on
Value Comparison — stat-change arrows and before/after lines for equipment screens
