​
Overview

Set Interactable Objects is an HMD action that enables or disables interactions for selected scene objects. Choose the objects under Target Objects, then turn Object Interactions on or off. Selecting a parent object also affects its children. Other objects retain their existing interaction settings.

​
When to Use

  • Prepare for instructions: Disable interactions with task objects while the trainee reads instructions or watches a demonstration.
  • Begin practice: Enable interactions with the objects the trainee needs for the next task.
  • Control individual components: Change a specific child object’s interaction setting within a larger asset.

​
Parameters

​
Configuring the Action

1

Add Set Interactable Objects

Select the step where the interaction settings should change. Open On Entry in the Properties panel and add Set Interactable Objects.
2

Select target objects

Use Edit in Scene in the action header to select the objects to update. Review the selected objects under Target Objects.
3

Set the interaction behavior

Check Object Interactions to enable interactions, or clear it to disable them. Enable Wait Until Complete if the next action depends on this update finishing.

​
Selection Behavior

  • Selecting a parent object updates that object and its children.
  • Selecting a specific child object targets that component within the parent asset.
  • To disable interactions with several objects, select every object you want to disable.
  • To enable an object again later, add another Set Interactable Objects action targeting the same object and check Object Interactions.

​
Example: Enable a Valve After the Instructions

A trainee first reads instructions, then practices operating a valve. Disable interaction with the valve during the instructions and enable it when practice begins. In the instructions step’s On Entry actions, add Set Interactable Objects with:
  • Target Objects: The valve.
  • Object Interactions: Unchecked.
In the practice step’s On Entry actions, add another Set Interactable Objects action with:
  • Target Objects: The same valve.
  • Object Interactions: Checked.
The valve’s interactions are disabled during the instructions and enabled when the trainee enters the practice step. Other scene objects retain their existing settings.

​
Best Practices

  • Choose the right level: Select the parent to update the whole asset, or a child object to target a specific component.
  • Plan when to re-enable: Add the enabling action before the trainee needs to interact with a previously disabled object.
  • Verify the selection: Test that the intended objects respond during practice and that unrelated objects retain their settings.
  • Events — Configure the interactions that trigger transitions
  • Entry Actions — Prepare a step before trainee interaction
