first of all, I'd like to say this: STL kicks massive amounts of butt. I got all the NPC's and other entities in the map in a vector of objects and it was just so easy to do!

Ahem.

Anyway, onto the scripting language. Each object on the map has a name, and when the player activates the object (either by stepping on it or "talking" to it) it will find that object in the map's scripting file. Nothing new so far, but what I'm planning is to use STL vectors to store variables dynamically introduced in the scripting. There will be two vectors, one for the local variables (like whether a door is open) and one for global variables (like setting a flag when a major objective is complete). Local variables are erased whenever you change maps, while the global variables stay. Both get put into save game files. If a variable is undefined at an IF statement, then it is considered a zero value.

Here's a wee example of what it will generally look like:

How about having script variables. Mirc scripting and lord2 both have them. $string1 = (Henry The Eight)

Another option is to use flex, its will allow you to create a C file that will read in a file and return a stream of seperate symbols it can even to advanced pattern matching so you can do stuff like ignoring whitespace or not, getting strings in as whole symbols (like everything between " and ") and ignoring everything after a // for comments.. whatever you want.

I think there might be a c++ version of flex too.. but I never was bothered to find out.

yeah, flex rocks. There is (i think) a C++ wrapper for flex used in the flipcode article...or it might just be one for VC++, i forget. I know on Linux there is one.....could be portable.

I just make a simple script language like:
