Liquidfun – 2D physics engine for games

<p><pre><code> For applications on Google Play that integrate this tool, usage is tracked. This tracking is done automatically using the embedded version string (b2_liquidFunVersionString), and helps us continue to optimize it. </code></pre> Is this tracking functionality restricted to libraries by Google employees? Seems like it would be useful for all third-party library developers to see how their libraries are being used and can be improved.

<p><pre><code> &quot;For applications on Google Play that integrate this tool, usage is tracked.&quot; </code></pre> Imagine if every open source library did that.

They say that this is an extension of Box2D, not a really new engine. This is kind of important, because the simulation of soft spherical particles is a much easier problem than the simulation of rigid bodies. (Unless they are doing some fancy things I&#x27;m not aware of). Maybe, there is some complexity in handling both soft and rigid bodies, but I don&#x27;t think that there should be a problem.

I wonder why they came up with a new library instead of contributing to box2d directly? Unless they had to break box2d&#x27;s API (but off the top of my head, without looking at the code, it&#x27;s hard to see why they would have to)

It&#x27;s interesting how much Google is using Github. Will we see an acquisition of Github in the near future?

I didn&#x27;t spot a liquid (without particles) looking demo in the videos - would that be easy to make? Would you be able to make visuals look like Wii&#x27;s Fluidity game using this easily?

Looks like:<p>- OE-CAKE[1]<p>- Phun&#x2F;Algodoo[2]<p>Which may give some examples of what could be done with this.<p>[1]<a href="http://www.teq.com/blog/2010/03/oe-cake-physics-simulator/" rel="nofollow">http:&#x2F;&#x2F;www.teq.com&#x2F;blog&#x2F;2010&#x2F;03&#x2F;oe-cake-physics-simulator&#x2F;</a><p>[2]<a href="http://www.algodoo.com/what-is-it/" rel="nofollow">http:&#x2F;&#x2F;www.algodoo.com&#x2F;what-is-it&#x2F;</a>

How long before an emscipten js version?

It&#x27;s surprisingly reasonable that they did not use Python or JS for it. I wonder how they came up with this project though - do they want to boost Android&#x2F;NaCl games?

Shamelessly plugging my library for js : <a href="https://github.com/asadlionpk/SPHjs" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;asadlionpk&#x2F;SPHjs</a>

The liquid seems a bit compressible, more like balls of jello or rubber than water. Is that a difficult or costly problem to resolve when simulating liquids?

Anyone see the Strandbeest in the video?

The music fits surprisingly well, its Interstate by The Juice To Make It Happen, whoever they are.

I somehow expected JS...

Someone make a realistic surfing game!
