XML tutorial for Anniversary Edition

What is XML modding?

Binary data becomes converted into more human-readable form which allows easier modding. All supported file types can be seen HERE.

Okay, what do I need?

OniSplit will be your tool. It's part of AE. Installing AE spares you some work because it splits the level achieves right away and globalize some more data. Global data can be used in any level.

AE installed. What now?

OniSplit cannot be opened in a classic way. But you are lucky. Now we have a GUI (graphical user interface) for it.
Mac user will want to get "AETools"
Install instructions are on same page.
Windows user will want to get "OniSplit GUI" or Vago GUI
Unpack and put the executables into your "GameDataFolder" inside "edition" folder.

What mod possibilities do I have?

See HERE again. It's an overview what you could do. But note that some types can be more difficult to mod than other.
If you need some ideas look at this page: modding brainstorms.
If you want to contribute AE: bug-fixes and feature requests.
Check also the AE's current To-Do page and maybe there are fields that need a modder.

Is there an easy exercise to get me started?

Just see at the following table. Read left side if you use a Macintosh PC, read right side if you use a Windows PC.


Mac: PC:
converting an ONI file into an XML file
Open Edition's AETools_Data folder and create a new folder named "ONIfiles".


Run AETools, choose "Extract" tab.
Click on checkbox "Expract as .xml file".
Then click on "Extract .oni file(s)" and choose "ONCCk4_L.oni".
See "XMLfiles" in "AETools_Data". There you should find "ONCCk4_L.xml".

XML_tutorial_mac_1C_TN.png Open Edition's GameDataFolder and create two new folders named "XML" and "ONI".


Run the GUI, choose "ONI - XML" tab and its upper section.
Click first browse button and search for "ONCCk4_L.oni" inside the level0_Characters folder.
Click second browse button and choose the XML folder as target.
Now click on Convert button.

XML_tutorial_1C_TN.png
modifing the XML file
Open the extracted file with a simple text editor. Search for "HasSupershield" tag and set its value to "1". Save file. XML_tutorial_mac_2C_TN.png Open the extracted file with a simple text editor. Search for "HasSupershield" tag and set its value to "1". Save file. XML_tutorial_2B_TN.png
creating the ONI file
Choose "Convert" tab.
Now click onto "Select File(s) for Conversion" button and mark "ONCCk4_L.xml". Click "Choose" button.
Then click "Select Destination Folder". Search for your ONIfiles folder, mark it, and click "Choose button."


Made a mistake when modified the XML file? The terminal window would appear now and telling you the trouble making line. Find the line in you XML file and fix it. Line number isn't always accurate. (It can shift - often by 1.) Then try again creating the file.

XML_tutorial_mac_3C_TN.png

Goto "XML -> ONI" section.
Click first browse button and search for "ONCCk4_L.xml" inside the XML folder.
Click second browse button and choose the ONI folder as target.
Now click on Convert button.


Try THIS method if no oni file was created. Use then "onisplit -create ONI XML/ONCCk4_L.xml" and look for error messages. Find the line in you XML file and fix it. Line number isn't always accurate. (It can shift - often by 1). Then try again creating the file.

creating and installing a mod package

Choose "Package" tab. The GUI is actually pretty much self-explaining.
Fill the editboxes with following:

90000
Test
[Test]
1
That's a package to test new mods.
YourNameHere


Then click "Create package" button and search for your ONIfiles folder. Mark it and click "Choose" button.


AEInstaller should automatically open now, select your test package. Hit "Install!" button.

testing the modification
Let's test our modification. Therefore we start TCTF HQ redux (pre-last level). The supershield becomes automatically switched on at 51% overpower (301 healh points). "chenille" cheat works too. XML_tutorial_img6_TN.png Let's test our modification. Therefore we start TCTF HQ redux (pre-last level).

Answer: "Check out this overview."


Documentation status:

Aqua Dot-Green.png : available

ONCC Aqua Dot-Yellow.png
Character class. It contains weapon skills, behavior Ids, view radius, jump power, sounds, 3D model (TRBS), animation collection (TRAC), textures (TRMA), and much more.
The XML file contains also the character's body part material (CBPM), body part impacts (CBPI), and particles for animations (ONCP and ONIA).
ONCV Aqua Dot-Green.png
Character variant. 1) It's used to build up the hierarchy of randomness pools. Some characters with different appearance can form a pool for randomness. A flag in CHAR determinze if a character use one of these pools. 2) It can be also used to upgrade characters on difficult level hard - enabled by a flag in CHAR.
ONGS Aqua Dot-Green.png

working with XML files: good to know

  • capitalization rules (use of capital and small initial letters): You need to care about it because also Onisplit does.
  • text position in a line: most tags have some distance towards line begin. It is not needed but preserve the overview.
  • structure: some tags have children. Destroying the structure doesn't affect the reconversion but it is not good for the overview. Example:

good:

   <Instance id="4" type="IGSA">
       <Strings>
           <Link>#7</Link>
       </Strings>
   </Instance>

bad:

   <Instance id="4" type="IGSA"><Strings><Link>#7</Link></Strings></Instance>
  • code folding: A simple text editor (and being aware of the search function) is actually enough to work with Oni's xml. Anyway, big files might be easier to handle with code folding. So, if you like code folding, you maybe try Microsoft Visual ... Express (PC) or Xcode (Mac). Both are for free.
You can fold whole instances and parent tags.
Folded code can be previewed in Microsoft Visual Express applications. Xcode provides an extra scroll popup.

way without Windows GUI: window address bar

window_address_bar_preview.png

Put the newest OniSplit.exe into the "edition\GameDataFolder" folder and use the window's address bar (that's where you can see the directory in full length).

Delete that address, type (for example) the code below, and hit enter.

onisplit -extract:xml xml_dir level0_Final/ONCCkonoko*.oni

The star is good for mess extraction/creation and good for shorten long unique file names. ("ONCCkonoko_generic" will be extracted in new folder "edition\GameDataFolder\xml_dir".)


It's also a good idea to keep the code in a temporary opened text file. There you can easily modify the code for other files and doesn't need you to type it from beginning into the address bar. (Be aware of Windows' short cut "CTRL + C" for coping marked text and "CTRL + V" for pasting text.)

way without Mac GUI: the terminal

Put the newest OniSplit.exe into the "Oni/GameDataFolder" folder.

Open the Terminal program then "change directory" to the GameDataFolder (Type "cd " then drag the GameDataFolder into the Terminal window, now press the RETURN key)

At this point you can enter the OniSplit commands, such as:

   mono onisplit.exe -extract:xml xml_dir level0_Final/ONCCkonoko*.oni

("ONCCkonoko_generic" will be extracted in new folder "GameDataFolder/xml_dir".)
