  • Choppy playback of spine animation in cocos2d-x.

Hello,

We released our app two years ago, and the animations played very smoothly. But now we have been working on adding new animations, and I just noticed that now all the animations play much choppier in this newer version. It seems that it is playing them at at 24 frames per second.

Before the movements seemed much smoother. But now all my animations, even if they don't have much going on, they play choppier.

Has Spine changed the frames per second on playback in cocos2d-x? Is there a way to tell cocos2dx to play the json during runtime at lease at 30 frames per second refresh rate or even higher?

I wonder if this is a cocod2-x issue or if we are missing some line of code during runtime.

Thank you.

What was the old version (of the editor) you were using? I believe a long time ago we changed rendering to improve batching.

The Spine Runtimes don't use frames per second, they render interpolated at any frame rate. Choppy animations could be due to too much CPU usage per frame. If you spend more than 1/60th of a second (16.6ms) rendering and vsync is on, then you can miss an entire frame, dropping you from 60Hz to 30Hz. Use animation clean up, weights purge, and follow the other performance tips to ensure you aren't wasting CPU with your skeletons.

Most importantly, profile your app to actually see where the CPU time is going, else you will waste time "fixing" things that have no affect.
