I have a bunch of modelsUnderRay stuff (not yet tied up into a tutorial, but
lots of commented code an tips), here:

General tips and advice:

Optimising Models Under Ray calls:

Wall collision demo, using 2 rays in a V formation:

Same demo, with 'visible beams' for clarification

Same, with FPS camera view

One method of optimising, by casting rays at irregular intervals:

Thanks Directors!!!
All useful.

These are all very good. Can anybody recommend one for going up stairs??

Thanks

The 'ground height detection' example in my previous post should handle going
up stairs in a very basic way:

You might want to use a little interpolation of the z height as you go up a
step so it's not so much of a jolt though!
