Extensions

A collection of static extension method classes that add convenience APIs to Unity types, .NET collections, and system primitives. All classes are in the Paragon namespace and are available project-wide without additional using statements.

Architecture

Quick Lookup

I want to...	Extension	Method
Listen to Animator IK/Move callbacks	AnimatorExtensions	animator.AddIKListener(cb) / animator.AddMoveListener(cb)
Check if directory contains another	DirectoryInfoExtensions	parent.HasSubDirectory(sub)
Walk up the GameObject hierarchy	GameObjectExtensions	go.GetParents()
Move a GameObject to a scene	GameObjectExtensions	go.MoveToScene(scene) / go.MoveToActiveScene()
Negate a Contains check	ICollectionExtensions	collection.NotContains(item)
ForEach on IEnumerable	IEnumerableExtensions	source.ForEach(action)
Exclude items from a sequence	IEnumerableExtensions	source.Except(item) / source.ExceptNull()
Conditionally append/prepend	IEnumerableExtensions	source.AppendIf(cond, item) / source.PrependIf(cond, item)

Classes

Class	Extends	Description
AnimatorExtensions	Animator	Callback subscriptions for OnAnimatorIK and OnAnimatorMove via a hidden proxy component
DirectoryInfoExtensions	DirectoryInfo	Directory hierarchy checks
GameObjectExtensions	GameObject	Parent traversal and scene management
ICollectionExtensions	ICollection<T>	Negated containment check
IEnumerableExtensions	IEnumerable<T>	LINQ-style utilities: ForEach, With, Except, AppendIf, PrependIf, conditional ordering, tuple Select
