KoboldTouch v6.2 marks the third major milestone for KoboldTouch. It also marks the longest development cycle between two updates: exactly 30 days.
That’s 30 days packed with new features, improvements and bugfixes, there’s a new development blog for the work-in-progress “Angry Trains” starterkit and slowly but surely the documentation is coming together.
So let’s check out the exciting new features in KoboldTouch v6.2:
Objective-C Box2D Physics wrapper
The Objective-C wrapper for Box2D (aka “Boxjective2D”) is now in a state that I feel very comfortable with. And proud. It’s the only Box2D Objective-C wrapper that’s both fairly complete and supported and will be continuously improved. It’s also stable, super-slick and easy to use, highly efficient without compromising integrity (ie no @private vars) and you can always access the underlying Box2D objects.
The following Box2D components are wrapped in Objective-C classes, which is about 80% of the public API of Box2D (and I won’t stop there): Continue reading »

If you ever wanted to build your own 2D top-down view train driving game, here’s … well, the things you need to consider plus a rudimentary source code example. Because a train following tracks is not as simple as it might seem, unless you restrict curves and switches to 90° angles and allow only very short cars and locomotives.
Here’s a video of my example project. Any stuttering is due to the screen recording software taking a toll on my system combined with the video playback framerate not rendering 60 fps (I assume it’s the standard 24 or 30 fps for Youtube videos). The video shows a sequence of three runs with a medium curve radius, a large curve radius and a ridiculously small curve radius. The yellow line indicates the track being followed by the axles, the purple line indicates the car chassis position (center point between axles). Continue reading »
