Good tutorial. When I was playing around last night, I missed that Letters were one of the things you could script to spawn. I was disappointed that you can't seem to use most basic statics though. I wanted to be able to make openable sliding doors by disabling the closed version and then enabling the two sides of the open versions. Still, you can do a lot.
