Hello! As it currently stands, blast jumping classes, aka demos and soldiers, have access to the roof of the main red and blu buildings in my map; flat, uninteresting, prop-less roofs that can only be accessed due to them being low. While I could make them higher and/or make them interesting gameplay-wise, it would look weird architecture-wise, and tall buildings aren't what I want to do in this map anyway. So... What about triangular roofs that would make players glide off rather than stay somewhere useless? Is it possible? What's the minimum angle for them to work? Is there a special invisible block/entity that could ensure it working correctly? Basically, gliding in hammer 101 plz?
