Hiya I'm working on a research project to investigate the use of virtual worlds for speech and language therapy to people who have Aphasia following a stroke. We're trying to minimise the use of menus - most of our participants are unable to read - so where possible I want to allow people to use graphical buttons instead of navigating a menu. It would be nice to allow people to control the sun position using a HUD, i.e. to be able to click a button to change to midday, sunset, midnight etc. Is this possible? I can't seem to find any way to script this directly (if this _is_ possible, please let me know!) but I was wondering if it's possible to trigger keyboard shortcuts via a script, so that I could use the viewer's built-in shortcuts for changing the sun position? Again I haven't found anything that says it's possible, so I thought I'd ask here in the meantime while I continue my search. Any advice/pointers gratefully received. Best wishes, Treee
