# Animation State {#Animation-State}
When an entity with any kind of animation is created, an 'animation state' object is assigned to each animation. This allows you to control both the weight and the time position (where applicable) for applying the animation to that specific entity. You can reuse the same animation definitions across multiple entities, and OGRE handles the internal management of this reuse.
