First of all, you'll need FPI Editpad if you want to start scripting.
D
ownload FPI EditPad
These are some great tutorials;
xplosys Scripting Tutorial
Plystire's AI Scriptin Tutorial
Try recreating the sample scripts in both tutorials, as a starting point which you can build upon.
Secondly, sorry team requsts are NOT permitted on these forums.
Thirdly, Missiles and escalators have not yet been introduced into FPSC, to my knowledge) and so this could be the perfect oppertunity for you to create some scripts. Cars work well with Project Blue (or PlyMod), through scripting.
Mostly, you'll have to learn how to script before anything great is achievable in FPS Creator.
Best of Luck
