Video: Bending physics engines to your will for fun and profit

At GDC 2015 QWOP creator Bennett Foddy shares tips for eliminating those dreaded 'floaty physics' without causing instabilities -- along with some weird tricks for abusing physics engines.

Modern game-making toolsets like Unity typically rely on physics engines (like PhysX) to simulate the game world.

This is useful but, as game developer and teacher Bennett Foddy explained at GDC 2015, it can make it difficult to tune your game so that it has a specific "feel" other than "vaguely floaty."

In his talk, Foddy (creator of physics-based timesinks like QWOP) offered fellow game makers advice on how to make their work feel "solid" without having to write their own physics engine. 

He shared strategies for eliminating those dreaded 'floaty physics' without generating instabilities -- along with some weird tricks for abusing physics engines.

It was a lighthearted and fascinating talk, one that you can (and should) now watch for free over on the official GDC YouTube channel!
