` over the canvas, and `Dialog` builds a titled panel with buttons inside it. - [Move a 3D character controller](/skill/references/recipes/character-controller-3d): A `CharacterController` is a kinematic capsule that collides and slides. - [Load a model](/skill/references/recipes/load-a-model): A `.glb` or `.gltf` file loads as a `ModelAsset`, and a `Model` component instantiates it under an entity. - [Load a tilemap and give it collision](/skill/references/recipes/load-a-tilemap-with-collision): Three components share the work. - [Move a 2D platformer character](/skill/references/recipes/platformer-controller-2d): `CharacterController2D` is a kinematic capsule or box that collides and slides through Rapier. - [Play a positional one-shot and a music loop](/skill/references/recipes/play-a-one-shot-and-a-loop): The mixer is a tree of named buses declared in a `.audio.json`: every sound plays on one, and a bus's volume multiplies through its children. - [Raycast and catch a trigger in 3D](/skill/references/recipes/raycast-and-trigger-3d): Two ways to ask the physics world a question. - [Rebind a key at run time](/skill/references/recipes/rebind-a-key-at-runtime): `performInteractiveRebind` listens for the next control the player touches and writes it onto one binding as an override. - [Save and load game state](/skill/references/recipes/save-and-load-game-state): `app.storage` is the asynchronous key–value store behind save games, settings and input rebindings. - [Show a gameplay counter in devtools](/skill/references/recipes/show-diagnostics-in-devtools): `@ignifx/devtools` draws the overlay; every number on its Stats panel comes from `app.diagnostics`, which is core. - [Spawn a prefab on click](/skill/references/recipes/spawn-a-prefab-on-click): A click is a ray. - [Spawn a prefab](/skill/references/recipes/spawn-a-prefab): A prefab is a scene file (ADR-0005): the same `ignifx.scene` format, loaded as a `SceneAsset` and stamped out with `world.instantiate`. - [Follow a character with a third-person camera](/skill/references/recipes/third-person-camera): `ThirdPersonCamera` is an orbit rig: it puts the entity carrying the `Camera` behind `target`, at `distance`, offset by `shoulderOffset`, and damps toward that pose. - [Tween a transform](/skill/references/recipes/tween-a-transform): `app.tweens` is core: it interpolates any number, `Vec2`, `Vec3` or `Quat` property of any object, on the game clock, in `PostUpdate` — so a tween honours `time.timeScale` and stops with `app.pause()` unless it asks for `updateWhenPaused`. ## File formats -
