Centipede++ is based on the arcade games 'Centipede', 'Millipede' or also known as 'Multipede'. This re-implementation of the game was mainly inspired by 'Multipede' available online: https://archive.org/details/arcade_multiped

Centipede++ is implemented using C++ and the SFML library (https://sfml-dev.org)

A Game class manages which State or Scene requires Input, Updates, or Rendering.

A State interface can be implemented to form specific states/scenes such as a:

• PlayState --> Game Play
• SplashState --> Beginning Instructions Screen
• PauseState --> Pause Screen
• and GameOverState --> Game Over Screen

From which the Game class will switch between, to form different scenes.

A specific state is responsible for handling input, providing renderable (SFML Drawable) objects, and updating the position of these objects over time to create motion.

To simplify the responsibility of a state for cases where there are many renderable objects such as the game sprites, another abstraction could be made.

An EntityManager stores a list of GameEntity objects. The EntityManager is responsible for calling an entity's update function; where an entity can update its own position or even update its texture to create animations. Since the GameEntity objects do not know where the other entities are, it is also the responsibility of EntityManager to check for GameEntity-GameEntity collisions; It would then call the entity's collision-handling function providing information about the other entity. The entity manager will also handle requests that the GameEntity objects might make such as: requesting to be deleted, or requesting to spawn in another entity at a certain location.

Finally the GameEntity class therefore forms a base for all the entities:

• Ship --> the player's moveable ship that fires bullets.
• Bullet --> Spawned in by the ship, it has can collide and destroy other entities
• CentipedeSegment --> A single segment of the whole centipede. Many of them form the centipede.
• Mushroom --> the player can shoot these to prevent the centipede from bouncing off them and moving closer downward.
• DDT Bomb --> when shot will release an explosion cloud that obliterates all entities it touches.
• Spider --> An enemy that moves in a ziz-zag manner near the player area, an occasionally eats mushrooms.
