The if and if else statements

[T122002]

Hello everyone! I have a question to ask.

Most script functions I have a general idea on how to use, but I do not understand how the "if" and "if else" statements work, or how or when to use them. I think after I learn those two statements, than I'll start working with loops and try to mess with puzzles a bit more.

Well, for example, say I want the player to pick up a key, then when they leave the room the key was in, a monster spawns. Or maybe when you do something, like solve a puzzle (I also don't know how to do puzzle scripts), then something will happen.

Can anyone explain to me how to do this, like dumb it down so I can understand and maybe throw in a few examples for me to study? That would be much appreciated!
