The
IEDP has everything you need to know about triggers, and other things.
Triggers are the same as conditions. That's what you want when you want to tailor something to a particlar condition. You'll use them a lot, so you might as well get comfortable with them. I would recommend copying and pasting the whole thing to a searchable text file so you will have the information always on hand, even when the internet is down.
Actions are just what they bill themselves to be. That's stuff you can do in a state. Advance time, cast a spell, advance a global variable, make a character do something, like die, etc. You'll use them a lot, too, so the same advice applies.
Identifiers is something you're just going to have to play with a bit. Basically, it contains all the syntax that makes it all work. It contains the things like class codes (FIGHTER_ALL) and time of day checks, and all that happy horse-doodoo that makes the world go round. You'll use it all the time, but there's no way you'll ever get around looking it up every time, so don't bother. Consign yourself to bookmarking the
IESDP and get it over with.
CLUA console stuff is always useful for playtesting, but a lot of the CLUA console commands are also valid actions, so you might want to get familiar with them.
You will use
Areas literally all the time, so I recommend you copy and paste that one too, so you can reference it offline.
Color gradients, or Colour Gradients, as the rest of the world calls them, is something you'll only need once in a while, but it's still nice to know it's there when you need it.
Thus ends the sales-pitch for the
IESDP.
