Actions

Overview

Actions are the fundamental building blocks of VRse Studio experiences. They define what happens in your VR world - from moving objects and playing sounds to updating user interfaces and controlling player behavior. This comprehensive reference covers all available actions and their implementation based on the current VRse Studio codebase.

Understanding Actions

Actions are executable instructions that define specific behaviors in your VR experience. Each action performs a discrete task such as:

Manipulating objects in the 3D environment
Playing audio or visual media
Updating user interface elements
Controlling player movement and interactions
Managing game logic and flow

Structure

Every action follows a consistent JSON structure:

{
  "Name": "ActionName",
  "Query": "TargetObjectName", 
  "Option": "SpecificOperation",
  "Data": "{\"parameter\":\"value\"}",
  "Type": 0
}

Components:

Name: The action type identifier
Query: Target object name (when applicable)
Option: Specific operation within the action type
Data: JSON string containing parameters
Type: Legacy field (currently unused, reserved for future functionality)

Note: The Type field is currently not used in the system and has no functionality. It is maintained for backward compatibility and may be utilized for future features. Always set this to 0 for actions.

Common Parameters

Most actions support these universal parameters:

waitForCompletion: Boolean indicating whether to wait for action completion before proceeding
targetTransform: Reference to target position/rotation object
duration: Time-based parameter for timed operations
lerpSpeed: Animation speed for transform operations

Action Types

Actions are organized into several categories based on their functionality:

Category	Purpose	Examples
