Hi. I’m wondering if there might be a way to download the engine documentation (particularly the programming guide) in HTML or PDF form for offline use. Is this available? Could it be made available? A PDF would be especially good so I could print hard copies. (On the other hand, I could probably do some conversion of the HTML.)
Bump people !!!
We don’t currently offer an offline version of the documentation. There has been interest in this in the past as well so we will look into it. Our current focus is on making sure all the features of the engine are documented, though.
If you look around the forums hard enough, you may just find some people who have figured out ways to do get an offline version already.
