I wrote these since I always get stuck and then later on I find it out.
1. Try to use stuff that doesn't need downloading, this is like lights, emitters and models..
2. Don't bother trying to copy protect your script. It will not work. I've ripped open Bleh7777's installer and used that.
3. DSOs are your friend, you can still find functions by looking inside them.
4. To find function names, open the console, press space then tab or type a bit of the function's start name in and keep pressing tab. I've found a few good ways.
I'll add more in the future.
