So, I’ve been doing some more work on Rotat towards rotation. In this tech demo, the wall collision has been removed in favour of the ability to climb walls.

I am certain that this has opened up some interesting gameplay possibilities – especially as the two behaviours can complement each other.

EDIT: The demo has been updated with more accuracy and wall clipping included. We’re still buggy, but coming…

This is an early demo of the newly rewritten Rotat Engine.

Left / Right walk, space jumps.

Some of the cool features it has:

• Tight, pixel-based collision detection.
• Real-time gravity.
• Camera control.

The core has also been made in a very robust MVC-like pattern.

This game will be a Handsome Lads game; as this is a technology blog, any further announcements about it will probably be made there.

NB: This content was lost in the great blog migration of 2009. I am working on an advanced version of it and will be sure to share when it is available

The pen draws shapes, the hand moves shapes and the X deletes shapes. Once you start drawing a shape, you can close it by clicking on the first point again. Also, the canvas (in white) is movable.

This is one of my personal favourite examples of my drawing API usage. This one uses some great trig to automatically curve as you draw.

The Rotat level editor will rely on this for user experience, and I believe it is intuitive. Please offer any recommendations to make it more intuitive.
