VoiceConstraint | Move Your Voice!【ModularAvatar】

Easily move your Avatar's 'Voice' around with VoiceConstraint! A versatile system to control where others perceive where your voice is coming from!
VoiceConstraint is an easy-to-add NDMF (Modular Avatar) install script that will move your Avatar's 'Voice' to a desired transform on a toggle!

Features:

・Moves your Avatar's 'Voice' to a desired location on a toggle!
・Use 'Existing Parameter' section to integrate with other prefabs easily!
・Two Constraint Type options available (Toggle, Between) with more to come!
・Support for having multiple prefab instances on a single avatar, so assets that use VoiceConstraint should be compatible with one another!
・Quest Compatible!

Installation:

[Dependencies]
・Modular Avatar: https://modular-avatar.nadena.dev/ [Version 1.10.0 or Newer]
・・Non-Destructive Modular Framework [Version 1.9.0 or Newer]

　1.　Make sure you have Modular Avatar and Non-Destructive Modular Framework installed. (NDMF installs with Modular Avatar through the Creator Companion.)
　2.　Import VoiceConstraint.unitypackage into your project.
　3.　Navigate to 'OrendCreations/VoiceConstraint' within your project. Drag-and-Drop the VoiceConstraint prefab onto your avatar.
　4.　Add a Constraint to the list of constraints, and explore the options!

Option Explanation:

・Name: The name of the menu toggle.
・Show In Menu: If the toggle should appear in the Expression Menu in the Voice Constraint folder.
・Existing Parameter: Use an Existing Parameter to drive the Voice Constraint transition logic. Useful if you want to connect VoiceConstraint to an existing prefab, or want it to automatically enable when a certain toggle is on!
　・Fallback State: When using Existing Parameters, what state to fallback to when the parameter is set to false. Default is the default head position. None does not attempt to move the voice when the parameter is set to false.
　・Invert Parameter: Normal usage sees the Existing Parameter as True = Enabled, and False = Disabled. Inverting will invert this logic.

Constraint Types:

・Toggle: Normal on/off state toggle to a single Transform.
　・Constraint Object: The object that the voice is constrained against.
・Between: Normal on/off state toggle between two Transforms.
　・Constraint Object1: The object that the voice is constrained against.
　・Constraint Object2: The object that the voice is constrained against.
・More to come!

Limitations:

・This asset does some odd things to your Avatar's Armature to be able to move the Voice around. It is possible other assets and addons may not work well with this! If you notice any bugs, please reach out to me on Discord or Twitter!
・This asset functions by moving your Avatar's Head Bone. Your nameplate's vertical position is also attached to your Head Bone, so using this asset may move your nameplate around!
・While moving your voice has been possible for a long time, it is an unintended feature, and may possibly break in the future D: If you want to read more about how it works, the VRChat Wiki has a good explanation on it.

Planned Additions:

・Look-At Constraint so the direction of the voice faces a specified transform
・Random Option to select a random transform from a list
