Detailed Description

Collision System class. Provides collision checks for SFML ConvexShapes. Provides SAT collision for narrow-phase checks and bounding box collision for broad-phase checks.

Remarks

Contains references to game lists.

Due to a bug with bullets (but not missiles for some reason), SAT has been disabled for all bullets (solely bounding box collision is used).

Constructor & Destructor Documentation

CollisionSystem::CollisionSystem	(	std::list< Ship * > &	shipList,
		std::list< Bullet * > &	bulletList,
		std::list< Pickup * > &	pickupList
	)

Creates a collision system with references to lists of entities from Game

Parameters

shipList	A reference to a list of ship pointers.
bulletList	A reference to a list of bullet pointers.
pickupList	A reference to a list of pickup pointers.
