I think it would be great if you had a script editor of some sort, within the actual world editor.

An example would be, attaching a script to a radius based zone. when the zone is entered, the script would execute.

But, I think it is also equally important to choose the right language. don't make the easy mistake of using lua or any other basic varient. Either a custom language or some form of OOP pre-existing language would be much better suited.

I'd vote for the former. It's not as hard as it might seem, and the end result is a language 100% tailored to your engine.

allready been suggested...
this kinda things can easely be done in C++, using headers, and functions.

Yeah, I've wrote sciprt engines in C# and a more obscure language bmax. But the difference between writing one yourself and 'lobbing' it into the game, and having one built deep within the engine and supported throughout the tool chain, is immense.

still i dont see any obvious reason, for adding a scripting language to the Esenthel engine...
also theres, in my oppinon, a lot of other things which should have higher priority!
