  1. GMNG 4312 –Game Engines Unit 02:Tools of the Trade Alireza Tavakkoli, Ph.D.

  2. Objectives • Tools of the Trade • Version Control • Visual Studio 2010 • Profiling Tools • Memory Leaks and Corruption Detection Tools • Other Tools

  3. Version Control • What is Version Control? • Multiple users to work on a project • Trace changes • Keep track of multiple modifications • Share the latest code • Avoid unintentional code corruptions • Even for one user • Keep a copy of the latest files on the repository • On multiple machines! • Version control keeps track of the history of the files! • Also called source control. • Can be used to keep track of text files and binaries as well. • Invaluable in Gaming Industry!

  4. Why Using Version Control? • Reasons to use version control • Central repository • Keeping history of changes • Tagging specific code versions for retrieval • Branching off from main development for patches and updates • As mentioned source control is also useful in single engineer projects!

  5. Common Version Control Systems • SCCS and RCS • Source Code Control System and Revision Control System • Oldest version control systems • Use command line interface • CVS • Concurrent Version System • Heavy-duty professional grade version control • Command-line based • Mostly in UNIX bases systems • CVSSNT (WinCVS) is the windows counterpart

  6. Common Version Control Systems • Subversion • Open source version control system • Popular for individual, student, small studio projects • We use this! • Git • Open source revision control • Used for linux kernel • Make changes to files  Commit to branches • Git can roll the diff(erences) and reapply them to new bases revisions  rebasing.

  7. Common Version Control Systems • Perforce • A Professional grade source control system • Change lists: • A collection of source files that have been modified as a logical unit. • Useful as a transaction processing unit • Either all changes within the list are submitted or none will. • NxNAlienbrain • A source control system for the game industry • Support very large databases • Specially for binary assets like movies, 3D models, etc.

  8. Common Version Control Systems • ClearCase • Very large scale software production • A Unique UI that extends the windows explorer functionality • Expensive! • Microsoft Visual SourceSafe • Light-weight source control package

  9. Subversion and TortoiseSVN • We use Subversion • It’s free • It’s nice and reliable • Easy to setup • Actually we use GoogleCode! • A number of windows and mac subversion clients • We use TortoiseSVN • Client-Server Architecture • Server contains the repository • Client connect to server to update the repository • Commits, Updates, Tags, Revisions, Branches, etc. • Let’s see how to set up our Source Version Control system.

  10. Setting Up Version Control • Code.Google.Com • http://code.google.com • Setup an account • Sign in • Go to project hosting • Create a project for Google Code (or Eclipse Labs). • Set up administrative options and users. • 4GB with 200MB upload size limit • Download and install TortoiseSVN • http://tortoisesvn.tigris.org

  11. Questions? • Game Engine Architecture • Chapter 2
