Python is commonly used for scripting in AAA game development. It is used in 3D modeling software like Maya and MotionBuilder for tasks like automating build steps. Python scripts can be used for continuous integration tasks like compiling code overnight and reporting errors the next morning. Python is also used for custom build steps, code analysis, debugging, and log file analysis. It allows integrating tools and streamlining workflows.

- 8. Third-Party Tools Scripting • Autodesk Maya (Python, MEL) • Autodesk Softimage XSI (Python, C#, VBScript, JScript, C++) • Autodesk MotionBuilder (Python, C++)
- 9. MotionBuilder – Integrated Python Editor
- 10. MotionBuilder – Python-based Plugin
- 11. Build Steps 1. Sync code (< 1 min) 2. Build editor (5 – 10 mins) 3. Sync data (< 1 min) 4. “Cook” data (1 min – 1 hour, depends) 5. Build game (5 – 15 mins) 6. Deploy to kit (sometimes) If only this was automated…

- 17. Many Other Examples… • Analyze MAP files • Custom build steps for SPU ELFs • Code sweeps • #include < > • Upgrading middleware • Fix C++ initializer lists • Locate debug information • Precompiled header optimization • Debugging • Log file merging
- 18. Logging System eg. For mismatched reference counts.
- 19. Logging System For each event: • Thread ID • Timestamp • Message • Callstack
- 20. Logging System Very big log files! • Log file is compressed using BZ2 • Parsing step handled in C • Script just sees event objects
- 21. Logging System Post-mortem log analysis via Python scripting.
