Questions
 

2 questions.
How do you make the inside of a house and how would you make yourslef enter the door/ect.
And if you are a leveler for a server, how do you upload it and know where to put all the stuff in the right place?

Okay when you open graal. There is an option called "Training" Click on there and press F4. This is where you make the level's them selfs. You click on the a folder located below the player list. In here you should have a file called "levels". If not you can't upload them. You drag the level's from your folder into the RC and it should be uploaded =]

How do you edit levels? Like if you ewant to edit a level, and you dont know what the whole thing looks like. And when I put items down there is no grass by it and it doesn't look good.

Apart from what snake said (which is correct) is that if you want the hole level to be for example (black) then take black and right click, you first need to start with the walls the outline how the level is going to look like, then you can mix up floor styles etc etc.. Try to be creative when you're making insides, try to come up with new stuff that will amaze the viewers eye's.

Oh question, how do I make signs work, and I am thinking about leveling for ourtside.

make an npc, better to use script's than the old graal way.

if (created){setshape 1,32,32}

Change the last 4 digits (32,32) but make sure you don't go under 10. It will be hard to locate it. Each tile is 16x16 in pixels. so 32x32 would be a square box. (The size of the sign).
Then you would add a

if (playertouchsme){say2 Your message here#b;}

The #b mean's there is a break. It will go off that line and continue onto the line below.
The whole script:

if (created){setshape 1,32,32;}
if (playertouchsme){say2 Welcome to Graal#b Have fun;}

A reason for the script is because you can also learn graal script. It's better to know the basic's than not know nothing =].

You could also add a

Message, replace this command with the say2 and see what happens =].

message Welcome to Graal =];

This will display the sign saying "Welcome to Graal =]". This can be used for alot of reason's. But if you want a graal char (An NPC) to say something you would use

setcharprop #c,Welcome To Graal;

Play around with this stuff, You will have fun =]

He could just use the default sign function, which I bet he would understand better ;)

And Yes i could, NP already helped me out with signes, but now, how do you put tile over tile without that green patch by it?

I don't understand what you mean :o
