Last night I started building a shooting game in AS3 using tangible objects placed on my touch screen. This was inspired by the video I showed in the previous post. The video below shows my first test with directional shooting, though I havent added targets in yet. Since my set up uses FTIR technology I could not use fiducial markers, so I decided to build ‘active’ objects that have two IR LEDs in the bottom and a push button on top. The first LED is always on and provides location, and the second LED is controlled by the push button which triggers the gun provides the shooting angle relative to the first LED.
