At ROBLOX Game Conference 2012, Kevin He dissected the steps he’s taken to refine ROBLOX’s water physics, hinges and motors so that vehicles – especially boats – perform more realistically. In this blog post, we’re recapping the key parts of the development process. You might be surprised at how much work goes into physically simulating real-world machines in a life-like fashion.
ROBLOX’s water, released in June, gives you the ability to create a boat that floats based on actual physical properties, rather than lines of Lua code. While the release of water marked a big step forward for ROBLOX, it has its limits; for example, if you want to create a propeller-powered boat, the propellers have to be on the side of the boat, as though they’re mimicking wheels on a car.
We’re working toward releasing a vehicle seat that gives players greater boat control, namely over rear-facing propellers that function based on real physical forces. It sounds simple, but it’s actually the culmination of two complex physics engine developments.Continue reading
