# Blueprint API Summary

Everything on this page is `BlueprintCallable` / `BlueprintPure` /
`BlueprintAssignable`: MovaInteract is designed so a pure-Blueprint project can
drive the whole system with no C++.

## Interaction

| Node | Class | Purpose |
|---|---|---|
| `TargetInteraction` | Interactor | Trigger the closest aimed interactable. |
| `TargetAction` | Interactor | Trigger a named Cycle/Group directly. |
| `TargetTags` | Interactor | Trigger by raw tag string. |
| `SetRadialSelectDirection` / `GetRadialSelectedIndex` | Interactor | Gamepad radial-menu selection. |

## Grab

| Node | Class | Purpose |
|---|---|---|
| `ToggleGrab` / `GrabAimed` / `ReleaseHeld` / `ThrowHeld` | Grab | Pick up / drop / throw. |
| `IsGrabbable` / `IsHolding` / `GetHeldComponent` | Grab | Queries for prompts and UI. |

## Save / load

| Node | Class | Purpose |
|---|---|---|
| `SaveInteractiveGame` | `UMovaIxSaveLibrary` | Snapshot every IC in the level. |
| `LoadInteractiveGame` | `UMovaIxSaveLibrary` | Restore them. |

## Presets

| Node | Purpose |
|---|---|
| `ListPresets` | Every built-in + user preset. |
| `ApplyPresetToComponent` | Replace an IC's bundle with a preset's. |
| `SaveUserPreset` / `DuplicateToUserPreset` / `DeleteUserPreset` | Manage user presets. |
| `GatherUnresolvedPresetNames` | Flag what a preset transplant needs wired before applying. |

## Decision hooks (override in a C++ subclass)

`CanExecuteGroup` and similar `BlueprintNativeEvent` hooks let a game apply
project-specific rules (permissions, quest state) without touching plugin code.
See {doc}`runtime-components`.

## Events to bind

| Event | Fires when |
|---|---|
| `OnInteractEnter` / `OnInteractLeave` | The Interactor's aim enters/leaves an interactable: drive your prompt widget. |
| `OnInteractHoldProgress` | A group with `ConfirmTime` is being held: drive a progress ring. |
| `OnGrabbed` / `OnReleased` / `OnThrown` | Grab lifecycle. |
| `OnRadialSelectionChanged` | The highlighted wedge changed. |
