Checks whether the UE5 editor is reachable via the Web Remote Control API. Call this first to verify the connection before attempting other operations.

Executes an Unreal Engine console command in the editor. NOTE: UE5 does not return success/failure for console commands — the response will be empty even if the command is invalid.

Calls a UFUNCTION on a UObject via the Web Remote Control API. IMPORTANT: Some functions on component sub-objects (e.g., LightComponent, RootComponent) are marked 'unavailable remotely'. Use actor-level functions like SetActorScale3D, SetActorTransform instead.

Gets the value of a UPROPERTY on a UObject. NOTE: Component properties (e.g., RootComponent, LightComponent) are often unavailable remotely. Use ue5_call_function with getter functions instead.

Sets the value of a UPROPERTY on a UObject. Supports undo (Ctrl+Z). NOTE: Component properties (e.g., RootComponent, LightComponent) are often unavailable remotely. Use ue5_call_function with setter functions like SetActorScale3D instead.

Gets all actors currently in the active editor level. Returns an array of actor object paths.

Spawns an actor in the level from a static mesh asset or an actor class. Use objectPath for static meshes (e.g., '/Engine/BasicShapes/Cube.Cube') or actorClass for native classes (e.g., '/Script/Engine.DirectionalLight').

Removes an actor from the current level by its object path.

Applies a material to a StaticMeshComponent on an actor. The component is accessed as '.StaticMeshComponent0'.

Lists assets in a Content Browser directory. Use '/Game' for project assets, '/Engine' for engine assets.

Creates and opens a new empty level at the given asset path.

Saves the currently open level.

Renames an asset in the Content Browser.

Duplicates an asset in the Content Browser.

Deletes an asset from the Content Browser.

Saves a specific asset.

Builds light maps and reflection captures for the level. NOTE: This may take a long time and block the editor.

Pilots an actor in the active editor viewport. Useful for seeing through a CameraActor.

Ejects the currently piloted actor in the editor viewport.

Spawns multiple actors in sequence. Useful for generating forests or large scenes quickly.
