One way to display information on the NXT screen is by using a “RIC” image file. Most of the default graphics that you see on the NXT use this file type. For example, the the sample “Try Touch” program file that comes with the firmware uses “faceopen.ric”:
Unfortunately there is no way to create or edit RIC files with the NXT-G. LabVIEW (LVLM or LV4E) has a RIC editor to make simple bitmaps, but RIC files are even more advanced. For example, it is possible to create objects that move around on the screen.
This video shows a shooting game where you try to shoot objects falling down using the buttons on the NXT. You move the cannon with the LEFT and RIGHT buttons and shoot with the ENTER button.
Stay tuned for more details on how to create your own games on the NXT screen using RIC files!
