# Glossary

| Term | Meaning |
|---|---|
| **IC** | "Interactive Component": shorthand for {cpp:class}`UMovaIxComponent`, the one component that makes an actor interactive. |
| **State** | A named pose (Location/Rotation/Scale/Visibility) plus optional audio/FX/physics/lights/animation/params. See {doc}`../concepts/states`. |
| **KeyFrame** | A `Time` paired with a `State` name inside an Action's timeline. |
| **Action** | One `Target` driven along an ordered list of KeyFrames. |
| **Group** | A set of Actions that play together as a unit, with its own easing, looping and gate settings. See {doc}`../concepts/groups-and-cycles`. |
| **Cycle** | An ordered list of Group names. Each trigger moves it one step (closed → opening → open → ...). |
| **Interactor** | {cpp:class}`UMovaIxInteractorComponent`, added to a pawn, that finds and triggers the interactable a player is aiming at. See {doc}`../guides/interactor`. |
| **Target** | An address string naming what an Action animates, or what a Cycle/Group runs on. See {doc}`../concepts/tag-grammar`. |
| **Gate** | A Group-level `Gates` list (every entry must pass before the group starts) or an inline `?<address>:State` condition on a tag (gates one target). See {doc}`../concepts/gates`. |
| **Flow** | The first character of a verb token: `!` parallel, `>` choice, `+` extension. |
| **Proximity** | A Box/Sphere/tagged-Volume trigger on the IC with Enter/Leave tag lists, firing interactions on overlap alone. See {doc}`../concepts/proximity`. |
| **Carry** | The mechanism by which an animated target ferries objects resting on or inside it. Decided once, at group start. See {doc}`../concepts/carrying`. |
| **Bone target** | An address like `@DoorMesh/hinge_01` that drives a bone of a Poseable Mesh directly. See {doc}`../concepts/bones`. |
| **Preset** | A JSON snapshot of an IC's whole interaction bundle (cycles + groups + states + tags + proximity), reusable across actors and projects. See {doc}`../guides/presets`. |
| **Grab** | Physics pick-up/carry/throw via {cpp:class}`UMovaIxGrabComponent`, independent of the IC system but composable with its tag grammar via `OnGrabbed`/`OnReleased`/`OnThrown`. See {doc}`../guides/grab-component`. |
| **Special state** | A runtime marker (`@Zero`, `@Current`, `@Start`, `@Loop`, `@Stop`, `@StopNow`) usable as a KeyFrame's State without being a written entry. |
| **`@`** | Selects an internal component by name (or `@=Tag` by tag). |
| **`%`** | Selects an external actor by tag. |
| **`#`** | A logic-resolved special (`#Self`, `#Parent`, `#Root`, `#Actor`, `#Carry`). |
| **`^`** | Delegation suffix: hand the rest of the address to that element's own IC. |
| **`:`** | State suffix: `:State` tests/filters by resting state; `:!State` negates. |
| **`?`** | Inline gate prefix on a tag. |
| **`*`** | Wildcard glob inside a name (`@Door*`). |
