Since using Unity, I’ve been trying to replicate a pipeline that’s similar to Flash. Being able to use Flash’s environment for hand-polished 2d animation just can’t be beat, unless you count custom developed tools. LWF from GREE shows promise in allowing you to bring your Flash animation into Unity, but there is some work involved in getting it to work!
With the mobile version of DONUT GET!, I tried a homemade Sprite Animation approach. This worked reasonably for the requirements of the port but it was more trouble than anticipated given the size of the texture sheets needed for so many frames of animation. Sprite sheets ate up RAM like nobody’s business and easily crashed lower-end devices.
Late last year GREE announced a godsend, LWF. It’s an Open Source tool to export Flash animation from SWF’s into Unity or HTML5. This was around the time I released DONUT GET! on mobile (which was GREE integrated) and I was excited to try it out. Unfortunately, the first release required you to compile it yourself and the only info I could find was in Japanese. Later on I found out that GREE posted more information and a super helpful video walkthrough on the Unity forums.
