Everything is still up in the air so far as I know. I was able to follow the compile instructions, and ask some questions along the way on these forums to get up and running on Mac. These are the steps - they should work for any platform:
1. Checkout Playscript-Mono through git from github.
2. Compile it using the instructions on
mono-project.org3. Set Xamarin Studio (or build your own copy of MonoDevelop, and set it there) to use the mono framework you just compiled (you can also just replace the compiler exe in the bundled Mono version, but I found it cleaner to do it this way).
4. Checkout some of the AS3 playscript demos (like the Away3D demo).
5. Compile and test the demos!
You may also want to install the AS3 syntax highlight support for Xamarin Studio - the mpack is in the google group archives somewhere. I'm not sure how to compile a copy of that from source (anyone?).
Note: I haven't tried to test the demos lately, and have no idea if they are in sync, or are still compiling or not as they are today - but a couple of months ago they definitely worked!
That's not a tutorial, but hopefully it's enough to get started. Good luck!
