# Creating Animation The Animation tool allows you to create animation on assets such as 3D objects, audio, particles etc. This could be something simple like changing position, rotation, or scale, as well as animating a texture, or adjusting volume on an audio asset. There are *many* elements of many asset types that can be animated. For more information on how to create animation in Unity, go to [Animation in Unity](/create/building-spaces/improve-your-space/animation-in-unity.md). It is also possible to import animations from other programs such as Blender, Maya, 3D Studio MAX etc. For more information on importing animation from external applications, go to [Importing Animation](/create/building-spaces/improve-your-space/importing-animation.md). To use Reactor, you need to have more than one animation, allowing Reactor to switch between them, and the method of navigating multiple animations is through the Animator window. A simple door could have different approaches to it such as : * a single frame closed animation and a single frame open animation where the Animator component will transition between the two. * A single frame closed animation, an open animation (that isn't looped), and a close animation (that isn't looped). There are more ways to make it work, it just depends on how you want the door to work. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.monaverse.com/create/building-spaces/adding-interactivity/mona-reactor/creating-animation.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
