## Cocos2d-like Actions for Unity3d

Cocos2d Actions for Unity3d
Unity3d is a very good game engine. It's almost perfect for quick prototyping.
After switching from Cocos2D to Unity3d, i'm still missing just one cocos's feature - actions.
It's a great combination of simplicity and flexibility, and i haven't found the suitable replacement for it.
Since actions are quite simple, i implemented them myself.

### Included actions (ready and WIP)

Base actions
- [x] Sequence
- [x] Parallel
- [x] Repeat and Loop *implemented in one action*
- [ ] Reverse

Interval actions
- [x] MoveTo
- [x] MoveBy
- [x] RotateTo
- [x] RotateBy
- [x] ScaleTo
- [x] ScaleBy
- [x] TintBy
- [x] Delay and RandomDelay *implemented in one action*
- [ ] TintTo
- [ ] FadeOut
- [ ] FadeIn
- [ ] FadeTo
- [ ] JumpTo
- [ ] JumpBy
- [ ] Bezier
- [ ] Blink

Instant actions
- [x] Place *renamed to SetPlace*
- [x] CallFunc *renamed to SendMessage*
- [x] Hide
- [x] Show
- [x] ToggleVisibility

### Some additional actions

Interval actions
- [ ] SkewBy
- [ ] SkewTo

Instant actions
- [x] SetRotation
- [x] SetTint

### Future plans
After completing these actions, i'm going to add some more to the list.

## License
Just like Cocos2D, this code licensed under the [MIT License](http://en.wikipedia.org/wiki/MIT_License)

## Help and donations
I'm not doing it to make profit, but if you want, [you can send me a couple of bucks via PayPal](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=Z64675TKXFRFU).

Also, if you'll write some action based on mine, feel free to send it to me, if you want me to add it to the library. I'll put your name on this page.
