~Understanding the Basics of Scripting~
by destinedjagold

Introduction...
Hello there pipz.
I'm destinedjagold, the maker of the Ruby Destiny series. This is my first scripting tutorial, so I hope this'll be useful for those who are new to hacking/modding...

Opening Message...
Okay, so I have read a comment where scripting tutorials were only understandable by those who already have experience in scripting/hacking.
So I decided to make a scripting tutorial that hopefully, will be easy to understand for those who are new to the fields of scripting...

Note...
  • This tutorial is for those who are new to scripting/hacking...
  • This tutorial uses HackMew's XSE tool...


I. The Syntax of Scripting
#dynamic 0x800000

#org @start
//commands here
end
That's the structure of the script...
To understand what those are, the commands #dynamic 0x800000 tells XSE where it'll store/write the script in your ROM.
#org @start is the beginning of your script. It's like a
front cover of a book. @start should not have any duplicates... It tells XSE that the script starts there.
The commands will be discussed later on...
And every book has a back cover, and that's what end is. It tells XSE that your script ends there.


II. A Simple Talking Script
#dynamic 0x800000

#org @start
lock
faceplayer
message @1 0x6
release
end

#org @1
= Hello World!
In the example script, you can then see that I have added some commands to our little script. Let's discuss the commands...
  • lock - It locks the PLAYER in place...
  • faceplayer - It makes the NPC face you if you talk to him...
  • message - tells XSE that a message box will show up containing texts...
  • @1 - the address of the message (remember that there shouldn't be any duplicates of any adress)
  • 0x6 - a message type. This is just an ordinary message...
  • release - tells XSE to unlock the PLAYER, so he can move again...


III. Addresses
And now, we have an address... If you recall, one of our commands in the example script is message @1 0x6 where @1 is an address of your message command.

#org @1
= Hello World!
What does address mean in scripting?
  • It tells XSE where to locate your messages, movements, or continuation scripts...
So, since you're the one scripting, you are telling XSE where your message is...


IV. Flow of Scripting
How does the ROM read the script?
Well, just like us, we read from top to bottom. The same towards scripts. XSE reads it from top to bottom...
#dynamic 0x800000

#org @start
lock
faceplayer
message @1 0x6
release
end

#org @1
= Hello World!
In this example script, XSE will start reading the script from the top, towards the bottom. So it first reads the #dynamic 0x800000.
Let's not discuss about how XSE searches for free space... This is a scripting tutorial, anyways...
The script will be read in a top-bottom method. So...
  1. lock will be read first, which locks the PLAYER in place...
  2. faceplayer is read next, where the NPC will face the PLAYER...
  3. then the message...
  4. since the message tells the script a location address of it's content, it goes to the address, which is #org @1, and then goes back...
  5. and then the PLAYER's released...
  6. and the script ended...
And so, in the game, the script will work like this...
  1. When you talk to an NPC, the PLAYER is locked...
  2. And then, the NPC will face the PLAYER...
  3. And then a message will display...
  4. And then, you are released...
  5. And the script ended...


~Putting The Script In Our ROM~
Newly Added - July 26, 2010

Opening Message...
Now you understand the basics of scripting. But now comes the question: how to we put it into our ROMs...?
It's quite simple. Here's a step by step procedure on how to do so...

Note...
You will need the following...
  • HackMew's XSE tool...
  • LU-HO's Advance Map tool...

Step-by-Step Procedure...

I. Step 1...
1. Open XSE...
2. Press CTRL + O or go to 'File' and click 'Open'.
3. Select your ROM (the one with the .gba extension).
Spoiler:


II. Step 2...
1. Write your script...
2. After you are done, click the 'gears' icon...
Spoiler:


III. Step 3...
1. After clicking the gear icon, a pop-up will appear...
2. The first address is usually highlighted first, and is usually the one you'll need.
3. Click the 'Copy' button...
Spoiler:


IV. Step 4...
1. Open Advance Map, and open your ROM through that tool...
2. Search for the event that you want your script to be inserted...
3. Write/paste the offset you copied from XSE onto the event's Script Offset in Advance Map (the '$' symbol should be there)...
Spoiler:


And voila~
You have inserted your script~

Okay, so that's the basics of scripting...

I might add something else in this tutorial but for now...

I cant believe I'm the first to reply, this helped me so much thanks!

The only problem for me is how do i link the Dynamic offsets to the sprites in A-Map?
you have to compile by going to xse and going to tool and click batch compiler and then you get a offset like for example.
If i compile destinedjagold script above and I get offset 800000 [which the first offset you used] I then put on a person event.
Hope I help!

Hey guys, I'm new here and just wanted to ask a 2questions?

I've searched alot to try and find the answer here but no luck...

My questions are:

1. In Xse, I do everything right, codes etc...follow them strictly step by step.
-----------------------------
#dynamic 0x800000

#org @start
lock
faceplayer
message @1 0x6
release
end

#org @1
= Hello World
--------------------------------

. When I test it, the character simply turns to me but he doesn't talk...Can't seem to figure out whats wrong. Any help would be greatly appreciated guys. ( Also, if I use FSF to find free space and I put it copy it to Xse, when I finish the codes and press compile, a box comes on saying that "THE ROM DOESN'T HAVE ENOUGH SPACE"..And the FSF option within Xse is unclickable , its not highlighted at all. Any tips also?
-----------
2. When I create a new house using a new map on advance map, I can't seem to enter the house when I test it. The screen goes black and the game freezes... All warps are correctly inserted and I've checked it so many times. Do you know what i'm doing wrong?

Thank you Everyone

okay this seems like a wrong question,but i need something REALLY simple. One script.I tried this, but I keep on messing up. All I want is for an old man to talk like "Hi!" or something. My first script; failed
Something like this should work:

#dynamic 0x800000

#org @start
msgbox @text 0x6
end

#org @text
= Hi!
When you compile it (the little gear button in XSE), It should give you an offset for @start (something after 800000, because that was the start of our dynamic offset).
Copy that offset, and in Advance Map select the old man as a person event and put your copied offset in his Script Offset box.

Can you help me? I want to learn how to make one of those scripts that activate battles in Pokemon Ruby. (Like starting a battle with Regice by pressing a in front of him.)
You need the wildbattle command.
The syntax is
wildbattle [national dex number] [level] [held item]
All three variables need to be in hex.
For the sake of example, let's say you want to battle a level 30 Raichu, holding a Potion.
Raichu's National Dex number is 26, which in hex is 1A.
30 (the level) in hex is 1E.
The Potion's item number is 13, which in hex is D.
So our code would be
wildbattle 0x1A 0x1E 0xD
A full example script would look like
#dynamic 0x800000

#org @start
msgbox @raichu 0x6
cry 0x1A
wildbattle 0x1A 0x1E 0xD
end

#org @raichu
= Raaiiiichuuuu!
-----

What is the code for your Rivals name? As its only [RIVAL] in advanced text..
In XSE, it can be either
\v\h06
or
[rival]
.


I just wrote all that from memory, but I can't see any errors in it right now.


If yo need more help, check out the Script Help Thread.

My feelings on
ROM hacking:

-I like scripting a lot.
-Mapping is almost as fun.
-Hex editing isn't bad at all.
-I do NOT enjoy spriting.
-I've been meaning to start learning ASM for a while, but I don't ever seem to have enough time.

Favorites:

-My favorite color is green.
-My favorite type is fire.
-My favorite Pokémon are:
Growlithe, Charizard, Mew,
Giratina, Haxorus, and Aggron.

I have another scripting problem, this one includes the money commands.

I am using ruby and it is a script box script. The point is a guy walks up to you, gives you money, then walks away. however, here are the problems:

Spoiler:
1. the showmoney command doesnt work, meaning the money box never appears.

2. the person ID is 0211 in Amap, and in my script I setflag 0x211 but he doesnt disapear


Here is the script:

applymovement 0x3 @move
waitmovement 0x0
msgbox @1 0x6

msgbox @2 0x6
msgbox @3 0x6
applymovement 0x3 @move2
waitmovement 0x0
setflag 0x212

#dynamic 0x800000
#org @start
giveitem 0x16 0x1 0x1
hidesprite 0x2
end


when i take a step after receiving it, the sprite reappears
That's where flags come in.
I haven't spare some time to add about flags, but there are scripting tutorials that covers this field in scripting.
