RPG Maker: Questions from an RPGM noob.

Yes, I admit it, I am a noob at RMXP. But I do Have RMXP Postality Knights, and I am learning how to use it. I do have a few questions though.

I can't remember all of them, so I'll ask them when they come up, but here I go.

1. Is there some sort of variable for the hero's name? If I make a name hero event, (let's say rename Arshes to bob.) is there some sort of hero name variable such as [heroname] or something that will allow the changed name to appear in a message? For example, instead of tytping out "Arshes, come here." I would type "[heroname], come here." so that what people name the character is what appears.

2. How do I make it so that when I am standing on an event square triggered by the action key, a message will only pop up if I am facing a certain direction? I made a dresser in a room, and when you stand on the event square, a description will pop up. But, no matter what direction you are facing, If you press the action key while standing on that square, the description will still pop up. How do I make it so that the descriptionwill only pop up if the character is facing up?

3. How do I make it so that when I stand on a certain square, an event will happen ONLY ONCE unless something is triggered to make it happen again? (Eg: getting out of a bed, it would pop up and say "It's a nice day outside" and then that message wouldn't pop up again when you stgand on that square again until you get out of the bed again?)

I'll ask more questions when I find them. Thanks for helping!

For your first question I think you use......
\n[n]  - replace "n" with the characters number in the database

For the 2nd question I don't really know what you mean

For the 3rd question it involves switches....which you can find out about here....http://rmrk.net/index.php/topic,12488.0.html

Conditional Branch

#3: you can make conditional branches with switches that turn on and off or you can make the event on the bed itself so when you get into the bed you go to sleep (music plays screen fades and whatever the hell else you want) then you have a move event that moves you one space out of the bed and a message after it that says whatever you want that way the event only happens if you walk into the bed instead of beside it

remember events can be as long as you want and they can last through multiple maps as well
