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

Two steps in Game design process:Step1: Build the concept

1.Get an idea2.Build the game concept 3.Creat a goal4.Creat an emotional experience for the

player.Step 2: Creating the game specification 1.Write the design document

2.Build the prototype3.Chose and appropriate lifecycle model

6/1/2014 5Prepared by Pawar R.B. Gharda Institute of Technology

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

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

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

Every game has goal. All aspect focused the player towards achieving the goal

Games having following goals:1. To collect pointes2. To gain power 3. To reach the destination/target first4. To overcome obstacles5. To discover something's6. To eliminate opponents

6/1/2014 9Prepared by Pawar R.B. Gharda Institute of Technology

Point scoring game having no visible objectiveRacing and conquest type game having visible

objective1.In racing the player knows his/her position,

compare with opponent at any time2.In RPG pointes earned spend on improving the

attribute3. In strategy games, gather resource.4.In adventure games, collect items are used to

solve the something's

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.

The concept put dawn on the paper This will generate the outline and sketch of game

design This will help to move ahead or give up This stage technical constraint are not require only

unique feature take into account. Description of game working is given and result is

committed.

6/1/2014 14Prepared by Pawar R.B. Gharda Institute of Technology

Feature based description easy to understand Feature comes into account from rules Rule changes when detailed the program Reason for changes is the diff. rule interact with

each other.

6/1/2014 15Prepared by Pawar R.B. Gharda Institute of Technology

1.Vital feature(integral feature): This make the game work properly. In football game formation is selected first and the choice of

player made accordingly.2.Chrome feature:

Some feature not effect on the game but increase the enjoyment.

Story, look and feel of the game. Example: player choose the stadium.

3. Gameplay substitute: o Some features does not affect the game but provide lot of

choices to the player. o Ex: player can chose one on one with the computer or

multiplayer mode in LAN.

6/1/2014 16Prepared by Pawar R.B. Gharda Institute of Technology

1.Explain the developer how the game works

2. Provide the vision statement through out

development

3. Identify the feature that are chrome or integral

6/1/2014 17Prepared by Pawar R.B. Gharda Institute of Technology

Good interface design provide the user view with there is no restriction on controlling the game

Good interface are very useful in strategic games

6/1/2014 18Prepared by Pawar R.B. Gharda Institute of Technology

Initial stage rule should be guess Then more and more rule are added and new

rules is interact with old one and changes made, finally they became a hole.

Rules provide the different features One unit is affected then, affect all other unit

6/1/2014 19Prepared by Pawar R.B. Gharda Institute of Technology

Level design affect the core gameplay. Low level provide the more watching than playing Story oriented game provide more narrative character

so that user involve into game with lot of interest. Level should not be use to create deficiencies into

game. Accurate specification is given to level designer who

understand the rules Primary goal of the game design create interest in

reader and convey the design aspect without ambiguity.

Interest should be from start to end.

6/1/2014 20Prepared by Pawar R.B. Gharda Institute of Technology

Detailed game description: Basic concept: ◦ The idea should be informative and interesting

Background story:◦ This is necessary for adventure kind of game and not puzzle kind of

game Objective:◦ Reader should have clear idea of gameplay and provide more

detailed as possible in design documents

6/1/2014 21Prepared by Pawar R.B. Gharda Institute of Technology

Game play: ◦ Working of game from beginning to end, title screen

and option screen should be displayed, computerized opponent should be provided by Artificial Inteliggence, result of particular option should be known to player, information provide by help option window.

Strategy required to reach end points are called the gameplay Rules are interact with each other or environment to generate

result.1.Implementing the gameplay: The game is series of choices The decision has gameplay value when it has an upside and

downside Each decision affect the next Decision include correct choice at the circumstances

6/1/2014 28Prepared by Pawar R.B. Gharda Institute of Technology

Dominated strategy: The choice witch is not using in circumstance is called dominated strategy

Dominant strategy: The choice witch is use in circumstance is called dominated strategy

Near dominant strategy are used in certain circumstances where above not work

It is widely use by the player Eg of near dominant strategy are given by asking

following question: What is the most common feature? Is the facility use only once then how much developing

time required? How much special efforts are needed to create interface

6/1/2014 29Prepared by Pawar R.B. Gharda Institute of Technology

Different option involve in gameplay Option may or may not be taken depending on factor Option can have time constraints Option does not affect the game much Option that is worth being taken Option that is never worth being taken2.Toolbox to assist with choices There is no particular method to create choices that are

left to the player Strategic choices are made for long term Tactic choices are made for short term or current There should be enough scope for good judgment
