Spritedow Animator is a simple and standalone alternative to Mecanim to animate sprites frame by frame.

Just drop your sprites or spritesheets to the editor and you will have an awesome animation in a jiffy (hehe).

NOTE
This plugin is oriented to programmers: althought it has a visual animation editor all the cool features need some code to work.

FEATURES
- Simple and easy to use Animation editor
- Animation preview
- Play animations forward or backward
- Play random animations
- Animate ignoring time scale
- Custom animation framerate
- Custom frame duration
- Basic events (onPlay, onStop...)
- Custom events
- Works with SpriteRenderer and UI Images
- Renderer control methods
- Make simple behaviours without code (loop, random, play on awake, delay between loops, disable renderer on end...)
- Completely standalone, this plugin does not use the Unity's animation system
