In the past I’ve mentioned some excellent libraries for creating special effects with Cocos2D with many featured in a massive Cocos2D example code listing, and this great example of how to create realistic water ripples.
There are many apps in which a trail is drawn following the motion of a user’s finger on the iPhone and iPad screen.
With a few tweaks games such as Sushi Chop, Veggie Samurai, and Fruit Ninja were able with a few tweaks to the width and some smoothing turn this simple effect into a sword slashing effect.
Recently I came across a library that allows you to easily recreate this effect using Cocos2D (versions provided using Cocos2D-iPhone and Cocos2D-X).
The library is known as CCBlade and you can see the Cocos2D-X version of this library in action in the game Rolly Poly:
You can download the Cocos2D iPhone version of the library complete with an example project on Github here.
If you are thinking of creating a slicer game with Cocos2D be sure to keep this library in mind.
