Core Game Design (Game Architecture)

  1. 1. Chapter : 1 Core Game Design 6/1/2014 1Prepared by Pawar R.B. Gharda Institute of Technology
  2. 2.  Information about game design  To make game interesting  Good game is that which provide good experience.  Programmer should know the game environment and various choices related to player and what is the content of that choices related to player. 6/1/2014 2Prepared by Pawar R.B. Gharda Institute of Technology
  3. 3.  Keep simple  Unique  Real time environment  Always used two player to play  Fun 6/1/2014 3Prepared by Pawar R.B. Gharda Institute of Technology
  4. 4.  For game development the skills required is creativity , craft, and technique.  Getting idea is the important requirement into game development.  Game design process is followed by concept, goal, plan, specification, code, test. 6/1/2014 4Prepared by Pawar R.B. Gharda Institute of Technology
  5. 5. Two steps in Game design process: Step1: Build the concept 1.Get an idea 2.Build the game concept 3.Creat a goal 4.Creat an emotional experience for the player. Step 2: Creating the game specification 1.Write the design document 2.Build the prototype 3.Chose and appropriate lifecycle model 6/1/2014 5Prepared by Pawar R.B. Gharda Institute of Technology
  6. 6.  Getting an idea:  Ideas come from dreams and inspiration  Programmer should come with unique idea  There is brief description What the game should be written.  This should measured in originality, potential audience(all age group, specific group, only girls and only boys)  Final idea are check and the concept is created. 6/1/2014 6Prepared by Pawar R.B. Gharda Institute of Technology
  7. 7.  Game concept:  Game is good if player win by doing unexpected things.  The game should have action(use many keys)  Adventure (story)  Puzzle(analytical thinking)  Educational(learning by doing )  Games likes movies combine different feature.  Adventure game combine action and puzzle 6/1/2014 7Prepared by Pawar R.B. Gharda Institute of Technology
  8. 8. Difference between movies and games  Require input from user  Player make decision in game  Game some time have no ending, one ending and multiple ending but movies have predetermine ending.  Game has rule and goals, players, objects, physics, sound, speech and emotion. 6/1/2014 8Prepared by Pawar R.B. Gharda Institute of Technology
  9. 9.  Every game has goal. All aspect focused the player towards achieving the goal Games having following goals: 1. To collect pointes 2. To gain power 3. To reach the destination/target first 4. To overcome obstacles 5. To discover something's 6. To eliminate opponents 6/1/2014 9Prepared by Pawar R.B. Gharda Institute of Technology
  10. 10. Point scoring game having no visible objective Racing and conquest type game having visible objective 1.In racing the player knows his/her position, compare with opponent at any time 2.In RPG pointes earned spend on improving the attribute 3. In strategy games, gather resource. 4.In adventure games, collect items are used to solve the something's 6/1/2014 10Prepared by Pawar R.B. Gharda Institute of Technology
  11. 11.  If emotional experience does not match the goal player not enjoy the game.  Design a game in such way that players get addicted.  Cool graphics, fast action stimulating strategy added to the game. 6/1/2014 11Prepared by Pawar R.B. Gharda Institute of Technology
  12. 12.  Score: ◦ player expect more from game experience than score. ◦ Fighting racing and sports  Moves: ◦ controlling virtual athletes' in sports and vehicle in racing required a steady practice.  Explore levels: ◦ Hide the some of the levels, move through the levels realize the hidden area, ◦ eg. Racing game having additional cars. 6/1/2014 12Prepared by Pawar R.B. Gharda Institute of Technology
