  1. Programming UnrealScript 2009

  2. File Types – Storage Location

  3. Object Storage • Unreal is partitioned using Packages • Each package can contain all of the files listed before • Almost all objects in unreal are stored in groups. • You can see how objects are stored in UnrealEd

  4. Compiler • UCC is a Command Line Compiler • To Compile use ‘Ucc make’ • To compile using a custom config use Ucc make –ini=‘<ini file>’ - Useful to avoid recompiling too much code, and reducing includes • .ucl, .u file in System Folder • UnrealScript runs at about 1/20th the speed of C++ Code

  5. Compiling the fast way • Don’t Forget the ucc.log file in the Unreal System Directory • It WILL save you loads of time when things get weird

  6. Editors • UltraEdit • Text Based Editor, Manage your own compiling, Classes, Files, etc • Fantastic File Search abilities • Wotgreal • All in one, compiler, editor, class manager Setting Up UltraEdit: http://wiki.beyondunreal.com/wiki/UltraEdit

  7. Engine Structure • Object Oriented • Massive Class Hierarchy • Almost everything in Unreal is a sub class of the class Actor • Actor is an extension of the Native Class Object • Native Classes are permanent, and you shouldn’t need to try to override them • Every visible object in the game world is an Actor, or sub class of

  8. Class Extensions • Nearly every Class you write will extend upon one of the Unreal Classes • You first Class will extend the Class Mutator

  9. Types of Mods • Mutator • Minor Changes in Gameplay • The only classes you can inherit from are Mutator, Info, and Actor • You can reference other classes, but more advantageous modders should consider a TC Mod • Total Conversion (TC Mod) • Can vary between minor changes, to a completely new game type • Classes can be extended from everywhere

  10. Running Mods • Muators appear automatically under the Mutator list in Unreal • TC Mods: • -mod=[Your Mod] • Log file view • Execute Unreal using ‘ut2004 –log’ • Mod .ini file • DefaultProperties in your mod.uc file will override the Ut2k4mod.ini file

  11. Keeping your code separate • UCC make –mod= • Only works when your mod has a UT2k4mod.ini file • Compiled files are stored in Mod\System Folder • You need to create a Default.ini and DefUser.ini in the Mod\System folder • For mutators to show up in the Mutator browser a .ucl file is required

  12. You’ll also need to remove the MyMod.ini and MyModUser.ini files when you recompile your mod • For a Simple Mutator this is excessive, and complicated • When you are building a TC Mod, this is Ideal • It makes you mod Portable, and easy for people to Play
