Code help/tutorials needed for SDL

Ok. Now that I started getting into SDL I have a load of questions. I really want to add outside atmosphere (particularly stars/moon and falling snow). I know I have all the files for it in SDL. Just don't know how to get it to work. Also, I use chaosedit and I know there are some options to enable it to work in there, i think?

I also want to enable 64+ walltile code. I see the Brother Tank code on DHW, but it's so long. Just wondering if SDL has an easier way of adding more walltiles...

Please help!

For the walls try this. I used it in ToS and if you open ToS demo with
ChaosEdit for instance you notice it enables more than 64 walls
(and more than 64 doors)...

I suppose you have commented out the correct defines
in version.h. Have you included the corresponding *.cpp/*.h
files in your project? If you have done this - make sure
that in ChaosEdit you have selected "use feature flags"
and the features you want to use...

This should work unless you have forgotten something.

Ok. Now I have starry sky and snow falling on level 1. haha. awesome! So easy just to uncomment stuff! Thanks!
