How can use actor

To use an actor in Reality Composer Pro, you can leverage the Actions API to create and manage animations for your entities. Here are the steps to do this:

1. Create an Animation Definition: First, create an animation definition for an entity using a built-in action. This could be actions like spinning or playing an animation.

2. Create an Animation Resource: Generate an animation resource from the definition. You can group these animation resources to play simultaneously or sequence them to play in a specific order.

3. Play the Animation: Use the playAnimation method on your entity to start the animation.

For custom actions, you can create your own protocol conformance of an entity action, generate an animation resource from it using the makeActionAnimation API, and then sequence it with other animations.

Here is a brief code example to illustrate these steps:

// Create a custom action
struct RobotMoveToHomeComplete: EntityAction {
    // Define your custom action logic here
}

// Create an instance of the custom action
let moveToHomeCompleteAction = RobotMoveToHomeComplete()

// Generate an animation resource from the custom action
let animationResource = try! AnimationResource.makeActionAnimation(moveToHomeCompleteAction)

// Play the animation on the entity
entity.playAnimation(animationResource)
