InstructionModule

The InstructionModule class enables effects to provide instructions to the user.

Example

//==============================================================================
// The following example demonstrates how to hide an instruction when more than
// one face is detected and show it if not.
//
// Project setup:
// - Set the 'Max Faces' of the 'Face Tracking' capability to 2 or more
// - Add the 'Instructions' capability
// - Select 'Custom Instructions'
// - Add the 'Try it with friends' instruction
//==============================================================================

// Load in the required modules
const Instruction = require('Instruction');
const FaceTracking = require('FaceTracking');

// Define a boolean that will be true until 2 faces are detected
var show = FaceTracking.count.lt(2);

// Bind the visibility of the instruction to the boolean
Instruction.bind(show, 'try_with_friends');

Properties

Property	Description
automaticInstructionsEnabled	(get) automaticInstructionsEnabled: boolean (set) (Not Available) Specifies whether or not automatic instructions are enabled.

## Methods

Method	Description
bind	bind(enabled: BooleanSignal, token: StringSignal): void When enabled, shows instruction for given token (you can find and select custom instruction tokens in project capabilities) To hide instruction simply set enabled to false. You can have at most one binding for instructions, meaning that setting a different binding would replace any previously created and setup binding for instructions.
