C# Scripting

Question

I'm wondering if anyone can help me with a scripting question. I'm trying to make a scripting system for a game engine. This scripting system has to load scripts so I can create objects and it also has to update the script if they edit the script while the game is running. That’s the problem. I know how to load the scripts and make the objects, but I don't see a good way of letting the designers edit the scripts while the game is going. Because there might be 20 instances of that object that have been created and have to change to the new script. Now with out that feature I just don't see a good reason to use scripts. If anyone can make this clearer for me that would be great. Thanks. Joe Micelli
