Topic One: Game designer

A game designer is a person who is involved in the development of a video game.

Game Designer

Artist

The artist is the person who creates images and graphics used in a game.

Artist

Sprite:

A sprite is simply an image that are attached to an object.

Sprite

Objects:

An object is a programmable container that can have an interaction or event.

The two types of objects used to construct a scene are active objects and backround objects.

Graphics

Active Objects

An active object can receive programming.

Active object:

Active objects are things like the player avatar, obstacles, and rewards

instance

instance:

An instance is an exact from inherits all the properties of the original object.

For example, if you are creating a brick wall, you will create several instances of a brick object to construct the wall.

Backround objects

Background object:

A background object cannot receive programming.

The background objects are used mainly to provide artistic design to the scene.

These objects develop the scene, but do not affect gameplay.

Static objects

Objects that are not animated are static objects.

static objects:

Not every object in a game will be animated.

In many cases, there is no reason for an object to be animated.

Animation:

An animation set is a series of images, or frames, with slight differences that are played in sequence to create frames of a single stepping motion, as shown in Figure 1-1.

Animation

Loop

Loop:

A loop is a repeating of an animation or sound when it reaches the end.

By looping the animation, a character can take several steps even though own a single step is animated.

Synchronization

Synchronization:

The process of matching the footsteps that the character is

Translation

Translation:

Movement of an object is referred to as a translation.

When the object translates motion to the right, this animation set should be played.

User interface:

A user interface (UI) is hwo the player (user) connects to (interfaces with) the game.

User Interface

Input interfaces

Input interfaces:

Input interfaces allow the user to give information to the computer.

When you press the keys on the keyboard, you are inputting letters and numbers into the computer.

Touch screen

Touch screen:

A touch screen is a video screen that senses pressure or electrical resistance from your finger to activate commands.

tilting

tilting:

Tilting uses an accelerator to sense how quickly you move the device and at what angle it is being held.

The accelerometer senses the movement of the mass like the marble and can calculate how much the mass has moved.

Output interfaces

output interfaces:

Output interfaces allow the computer to give you information.

Programming language:

Programming, or coding is the process of inputting commands that a machine will execute.

Programming language

Game engine

Game engine:

Game-design software, known as game engine, makes the job of computer programming much easier.

Object Oriented programming

assigns programming to objects.

Object-Oriented programming:

An object is a container that has properties and methods.

compiling

Compiling:

The process of changing computer code, scripts and other programming into a file that can run on a specific type of device is called compiling.

When a computer compiles, it takes the script the programmer wrote and rewrites it as an executable file.

Executable file

executable file:

As the name implies, an executable file is a program file that a computer can read and run.

The executable tells the computer exactly what it is supposed to do in its own language.

porting

porting:

When an executable is changed to make it compatible with a different device, it is called porting.

Clickteam Fusion 2.5 allowes the designer to create an executable for a personal computer and port the same file as an Iphone or Andriod executable.

Event Programming.

The objects displayed on the screen are just pixels.

Event programming

Pseudocode

Pseudocode is not actual programming code, rather it is based on English and used to record the programming logic.

Pseudocode:

Pseudocode is a quick way of documenting the action and reaction of an event so it can be coded later in the programming language.

When you press the keys on the keyboard, you are inputting letters and numbers into the computer.

Event editor

Event editor:

The event editor breaks down the psuedocode logic into condition event and action events.

The condition event described what must exist or become true.

Pixels

Pixels:

Pixels are the smallest picture elements displayed on a video screen.

The word pixel is a combination of the words picture and element as a single pixel is the smallest picture element of a digital image.

If/Then

IF/then:

The programming follows a logical design process that makes it easy to interpret an IF/THEN logic statement.

Almost all game interactions follow the IF... THEN logic of an event.

Output interfaces

output interfaces:

Output interfaces allow the computer to give you information.

Sound:

Sounds can be added as backround music or as part of the action.

Sound

Music:

Music

A long sound file is typically referred to as music.

This may be as long as a complete song.

Sample:

A short sound file is typically referrec to as a sample.

Sample

A sample may be less than one second in duration.

IF/Then:

IF a collision between the ball and brick, THEN destroy the brick.

If/then

common real-life action-reaction relationship:

IF you turn in homework- THEN you get a good grade

IF you buy a ticket- THEN you watch a movie

IF you miss the bus- THEN you are late to school

Common real life action-reaction relationship

common Computer action-reaction relationship:

IF user presses the [R] key- THEN letter R appears on screen.

IF user double clicks a program icon- THEN launch the program.

Common Computer action-reaction relationship

IF dart object collides with a balloon object- THEN destroy the balloon object.

Action-reaction relationship:

IF action- then reaction

IF cause- then effect

Action-reaction relationship

IF condition is true- then action is executed.
