Directed light question.

[Nevicar]

I've tried using a spot light but it never gives me the results I want, I can't get the actual light to go all the way down to the floor when I load the map and try to play it, unless you don't take the spotlight box and stretch it all the way down to the floor.

Am I missing something? Does there have to be a light behind the spotlight in order for it to actually do what I want it to do, or do I have to set the spotlight right up against the surface?

Edit: Also that picture isn't really true, that's what it looked like when I had my friend building it (he's building I'm scripting, and have no idea how the lights work) so he just slapped that on there.
