In the link, the first download. The very first called Castle : Exterior, in the chipset there is the door. You can map the sides and use the charset to make the animation of the door.

....You mean take a "screenshot", not "stamp" ^^"[/QUOTE]

Sorry, the key is called stamp so we name it stamp too XD

To open the chest you have to make the animation of the chest.

http://rpgmaker.net/tutorials/rm2k3/ try to read some tuts, this:

http://rpgmaker.net/tutorials/321/

is a chest tutorial. They are surelly better than my explainations XD

I thought the keyboard says 'printscreen', not 'stamp'. Oh well.

Hmm that treasure chest tutorial, I think it's using another version of rm2k3? It was even more complicated than your explanation lol. But thanks anyway, I've already did it by watching a tut video.

Also, what's the difference of 'switches' and 'variables'? Variables seems so complicated to use :/

[QUOTE]I thought the keyboard says 'printscreen', not 'stamp'. Oh well.[/QUOTE]

Well mine says stamp xD It uses 2003, maybe it's just long and all-written XD

Switches are only on and off, like a light switch, you can turn lights on or off. Variables can contain numbers and other, so you can use them to do a quest. Like, if quest is 0 a character talks you about the quest, if it's 1 the character ask you if you have done or other, if it's 2 you have complated it and character tells you other, with 3 the character tells you something general, and so on.

http://rpgmaker.net/tutorials/601/ there is the tut, with the light example too, lol XD

ARGHHHHHH!!!!!@$#@%@^@!!! Soooo wanna swear a million times!!! (don't mind me, chinese saying)

Anyways, I've found out I've had something called "Map Tree Data Break" when I've found out I couldn't open my maps for some reason. Yeah, it literally 'breaks' all your maps, and poof! They're gone.

Luckily, I've been taking screenshots of my maps so at least I can remake them and fortunately the maps aren't too many. I'll just have to do everything from scratch.

I'm still not sure how to prevent this when this happens again though. I've heard people say you make a back up of the game first. Then start a new project and add the number of maps you've had in your old ones to the new ones. So if you've made 7 maps in your old project, make 7 in your new one. Does this mean I can just right- click, new map, right-click, new map... again?

Also, they said to copy your corrupt '.lmt file' to your new project?! Um, does this mean after I've added the blank maps in my new project, I need to create a gamedisk again, then after that, copy and paste the ".lmt file' in the new one? Also, do I need to copy and paste my old maps (from the back-up) to the new file and open them again with rm2k3?

This is getting frustrating, now I know how 'Bad Luck' feels >.<
