programming

The player interacts with the game Objects (other characters, food, weapons, potions, cars, fuel, puzzle pieces, obstacles, currency, etc.) to attain this Goal.

Object contains BOTH:GRAPHIC: An Object’s appearance is determined

by the image or digital picture the developer assigns to it. The image is called a Sprite.

BEHAVIOR: An Object’s behavior is determined by events and actions (Conditional Statements )

During gameplay, certain Events will happen and cause specific Actions to take place (Ex: If Player collides with enemy, then 1 Life is lost).

Some objects react to player input (keyboard, mouse) and to other objects.

Consider the relationships with real-world physics and how a computer must be told to demonstrate them on the screen.

Mapping these concepts to Computer Science Theory

Each object has properties and behaviors encapsulated inside of it.

This entire collection of properties and behaviorscan be referenced through the object name

Creation Behavior – Start moving

Collision Behavior – Bounce

Left Mouse Behavior – Increase Score Bounce

Building behaviors is an example of Event Programming

Wait for some specific Event to happen

Perform some action(s) in response to it.

GOAL - Games need to have a Goal for the player to work toward.

CHALLENGE: In addition, Challenge is needed to keep the game interesting and engaging for the player. Various strategies are used to make the game more difficult for the player as they progress to higher levels or achievement.

ROOMS - A digital game takes place in a virtual environment laid out in Rooms. There may be one or many rooms. This environment may be a castle, forest, racetrack, or underwater cave.

ENHANCEMENT - Sounds and Backgrounds

may be added to enhance the environment and gameplay experience.

Cause and Affect in gaming is accomplished by CONDITIONAL STATEMENTS

IF cause THEN effect

In gaming, the “cause” is called an Event and the “effect” is called an Action.

IF event THEN action

The computer only knows as much as you tell it

The game is created by defining a set of instructions or conditional statements for the computer to follow.

Computer instructions must be clearly defined and appropriately sequenced, or an undesired outcome may result.
