Game development life cycle

  1. 1. GAME DEVELOPMENT LIFE CYCLE Prepared by Sarah Alazab
  2. 2. Acknowledgment  This presentation is based on a document titled “Lifecycle for Game Development to Ensure Enhanced Productivity” by K. Subhash Babu1 and R.Maruthi2  Professor & Head, Dept. of MCA, SSN college of Engineering, Chennai, Tamilnadu, India1  Associate Professor, Dept. of MCA, SSN college of Engineering, Chennai, Tamilnadu, India2
  3. 3. Index I. Introduction II. Game Development Life Cycle III. Conclusion IV. References
  4. 4. I. Introduction Many researchers described GDLC according to different software development models. Based on all these models, the most important phases are  The idea  Proposal  Design phases [2]
  5. 5. II. Game Development Life Cycle Developing the Story Developing the Script Feasibility Study Promotional Demo Designing Layout Designing Modeling Texturing Animation High, Module and Low Level Design Coding Testing Debugging Integration GameTesting
  6. 6. A. DEVELOPING THE STORY  A core theme with a well defined story line  Target a specific age group  Story starts with an idea then develops further  Characters, situations, events and places, relationships are determined  Conflict and resolution scenarios are added The translation of a story into a game is a mere conflict resolution.
  7. 7. B. DEVELOPING THE SCRIPT  The story is refined to obtain a tight script that ensures a seamless flow between levels.  Script writing needs a great deal of imagination and creativity.  The key is to capture the imagination of the audience.  Characters and backdrops are created and decided during this phase. The better the script the better will be the game.
  8. 8. C. FEASIBIBLITY STUDY  Assess the feasibility of a game.  Helps to freeze the requirements, the scope, profitability and other conclusions of the proposed game [4]. The areas to be analyzed in the feasibility study are:  Requirements  Pricing  Technical, organizational, cultural and legal issues  Schedule of the project
  9. 9. C. FEASIBIBLITY STUDY In this phase project leaders, project design and development personnel and research group will be working together to create a game as a complete product [5]. Programmers analyze and explain the programming limitations to the project managers. The outcome of the feasibility study is the feasibility study report, which contains :  Management summary  Technical specification [4]  The findings and recommendation
  10. 10. D. PROMOTIONAL DEMO  Promotional demo is needed to attract the potential customers.  Plan the promotional demo for the game and execute it.  A basic trial version or trailer since the game is not implemented yet.
  11. 11. E. DESIGNING  Character design Figure-2: Character designs
  12. 12. E. DESIGNING Figure -3 Background design-1 Figure -4 Sets and Props Designs • Background design • Sets and Props design
  13. 13. F. LAYOUT DESIGNING  Layout for the entire game and for all the levels.  The layout represents the various sets and passage ways with hurdles  Every type of game have certain constraints. Covering all is quite challenging [9]. Figure-5: Layout Design
  14. 14. G. MODELING  Character modeling, sets modeling and props modeling.  Models have to provide enough data so the finer details can be rendered in an effective manner.  Advanced techniques like the use of normal mapping[10]. Figure- 6 Props Modeling
  15. 15. H. TEXTURING Texturing is a technique for adding detail, providing surface texture or color so that a realistic look can be given to the characters, sets and props. It is very common in almost all the 3D applications. An example of textured design is given in figure-3. Figure-7:Textured model
  16. 16. I. ANIMATION Characters animation represent the sequence of actions in the game.  Frame by Frame Animation Key frames are snapshots of an image at a single point in time. Key frame animation is the cycling of key frames to give the illusion of movement. Figure-8 Frame by Frame Animation-1
  17. 17. I. ANIMATION  Motion Capture Animation Capture and record movement of the characters or objects enacted by humans or trained animals with either optical or magnetic sensors placed on them. These movements are later applied to the models. Requires expensive camera/magnetic systems and very specific hardware and software.
  18. 18. I. ANIMATION  Mesh Animation Mesh methodology (supports the deformations of Muscles & Joints. e.g., facials, biceps, skin movement on rib-joints for animals, etc).
  19. 19. J. HIGH AND LOW LEVEL DESIGN The high level design identifies all the elements in an abstract way hiding most details Shows relationships between modules in the form of data flow, flow charts, data structures etc. • In module design high level design is segregated into various modules.
  20. 20. J. HIGH AND LOW LEVEL DESIGN The low level design details the high level design (i.e) the logic behind each of the module is defined.
  21. 21. K. CODING  Coding for making the gaming interactive  Coding for implementing the interface design  2D Game Engines like GameMaker, Multimedia Fusion 2, Construct, Flixel, FlashPunk and Stencyl. Figure:10 Design interfaceFigure:9 GameMaker IDE
  22. 22. K. CODING  3D Game Engines are Unity , UDK , XNA , BlitzMax , jMonkeyEngine andTorque to name a few[11]. Figure:11 Unity Game Engine Figure:12 Unreal Development Kit
  23. 23. L. TESTING AND DEBUGGING This phase is carried out at the module level before integrating all the modules. Testing is to be done to make each and every module in the game to be free from errors and bugs. Most of the Games designing tools come with built in testing and debugging tools.
  24. 24. M. INTEGRATION  After testing, all the modules are integrated to get the final product. It is very similar to assembling the various parts of a product to get a complete product.
  25. 25. N. GAME TESTING  The game is tested for the complete flow from the beginning to the end  Identify bugs and fix them  Since it is a complex task which involves twists and turns, it is tested thoroughly to meet the expectations of the users. Examples of software’s for testing are:  GameTester 1.1  SeeTest  eggPlant
  26. 26. III. CONCLUSION  This paper gives an outline of the phases involved in the game development process and briefly discusses each of them  Following these phases can benefit all the team included in the game development to proceed in their game development process without worrying about any defects and shortcomings.
