The warp effect doesn't work on my computer, that's why I am wondering:
Can someone point me in the direction at how to create a warp-effect on a sprite, without using the ready-to-use effect from C2?
Without using a Webgl fx your best bet is a pre-rendered animation.
You can try some experimentation with the canvas effects, but none of those involve altering pixel location.
