The game Race the Sun have you flying directly towards the sun, so the long cast shadows warn you of areas to avoid:

I really like this idea, and would very much like to steal it! So I need this command:
SetSunDirection(-0.121, -0.104, -0.987)

And I need to set its values to ... something ... which places the sun just above the northern horizon. That is, right in front of the player, if he's facing in the Z direction.

But how do I figure out these weird values?

it is a vector. so set your sun position (p1) and then get the position you want the sun to look at (p2)
Then
SetSunDirection(p2.x - p1.x, p2.y - p1.y, p2.z - p1.z)

Oh, yeah, vectors. Those bloody vectors. I should know this by now. But it was way easy, it just ... worked. Thanks!
