bassbong Have a look through the example mod in [Install location]/Cosmoteer/Standard Mods
. Also, make sure when you start making mods, you install it in Documents/My Games/Cosmoteer/Mods
.
Start simple, like changing the range or damage of the laser blaster. Don't dive head first into modding buffs or railguns or things like that.
Make sure you have a proper text editor, like Notepad++, Sublime Text 3 or Atom (or similar), not MS Notepad. If you use Notepad++ or Sublime Text, I believe there are some syntax highlighting packs somewhere on the forum (I'll have to find them somewhere else, sorry). Using a proper text editor makes it easier to code and check that you've balanced brackets.
If you want to sprite, use Paint.net, Krita or GIMP. They're free.
