Pre-production Phase
•
•
•
•
•
•
General game idea or design
Back-story
Concept artwork
Storyboards
Game-play elements
Working prototype demonstrating key game features.
Mainstream production phase
•
•
•
•
•
Software designing
Implementing the game engine, sound engine, or 3D engine.
Implementing networking components.
Implementing input control.
Creating game assets such as textures, interface elements, 3D
models.
• Adding game-play elements such as artificial intelligence, cut scene,
in-game dialog.
• Producing game’s audio
Project Milestone
•
Pre-alpha version
– A lot of functional and asset/content-based decisions still have to be made.
•
Alpha version
– Satisfies most of the project goals and requirements while still requiring
extensive testing and debugging.
•
Beta version
– Generally has numerous bugs, stability and compatibility issues.
– Released to selected group (closed beta) as opposed to a larger community
group (open beta)
•
Release Candidates
– Very close to the final game release but still need some extensive testing to
ensure that no fatal bugs are present.

General Availability Release
Testing
• Unit testing
– Primarily done by programmers themselves
• Functional testing
– Based on scripts targeted at groups of classes
– Focus on user requirements and performance constraints.
• Automated testing
– Focus on the generation of test units reflecting the existing
programming units.
– Is conducted concurrently throughout the implementation phase.
Software Patches
• Patching is the most common form of maintaining and
updating computer games.
• Ensure that software regression doesn’t occur when
patch is released.
• Patches are not solely used for the correction of bugs
and are often released to improve or change some
game-play elements.
