Detailed Description

A system that handles the ball physics.

This system handles the unique aspects of ball physics, including bouncing off of walls and detecting successful scores. It acts on Entities with LocationComponent, VelocityComponent, and BallComponent.

Constructor & Destructor Documentation

BallSystem()

BallSystem::BallSystem	(	Dispatcher &	dispatcher,
		Entity &	player,
		Entity &	enemy
	)

Constructs a new Ball System.

Parameters

dispatcher	The dispatcher on which the system will post the PLAYER_SCORE_EVENT and ENEMY_SCORE_EVENT.
player	A reference to the player. Its LocationComponent is used for collision detection with the paddle.
enemy	A referece to the enemy AI. Its LocationComponent is used for collection detection with the paddle.

Member Function Documentation

process()

void BallSystem::process ( std::shared_ptr< Entity > &  entity, sf::Time  deltaTime  )

protectedvirtual

Processes a ball.

Processes a ball to see if it needs to bounce off a wall or has scored for either the player or the AI enemy.

Parameters

entity	The current ball to process.
deltaTime	The amount of time that has passed since the last call to process() for this ball.

Implements IteratingSystem.
