# Tweener

### Introduction

The Tweener object stores information about a tween. It is created whenever the [Tween](https://docs.flatredball.com/flatredball/api/stateinterpolationplugin/gluevault-component-pages-advanced-interpolation-plugin-tween-function) extension method is called, or it can be manually created and added to the [TweenerManager](https://docs.flatredball.com/flatredball/api/stateinterpolationplugin/tweenermanager).
