A Performance Benchmark of Javascript Game Engine in Mobile Devices

Collie.js is a high performance web animation library in mobile devices. but, How much faster is it than other libraries? so I have tested a simple animation on mobile devices.

A Simple specification of the test case

The Rabbit has a width of 129.4 pixel and a height of 165 pixel each frame.

There are 100 rabbits walking right. (Moving, Sprite Animation)
The Screen has a width of 320 pixel and a height of 480 pixel.
They will be always displayed inside of the screen. (the range of horizontal position is from 0 to (320 - 129.4))
You can check out a sample test case with Collie.js below

A simple rules for testing animation

Select a fastest result.
Each test are scored out of 100 points. When a test shows 60 FPS, It's scored 100 points.
Round off to the nearest whole number.

Conclusion

The Conclusion that Collie.js is the fastest javascript game engine in mobile devices could be drawn from the results described above. but, Faster isn't always better. Collie.js is just an animation library now. It should be improved in many features to create various games conveniently. In addition to this, Some Game Engines provide a native application like the Ejecta. so you couldn't decide easily what is the best javascript game engine. Try to make a sample with as various game engines as possible. It might help you to select a better one.
