Detailed Description

This defines CollisionObject boundaries and data for objects/backgrounds.

This class is tasked with the following:

• being a parent for collision bound types.

enum CollisionObject::CollisionObjectType

This is to be used for Type checking so as to make no need for dynamic_cast and it's inefficiency.

Todo:

make sure to put all CollisionObject children in here!

Member Function Documentation

bool CollisionObject::checkCollisions	(	const vector< CollisionObject * > &	c,
		const Point2D	cPos,
		const Point2D	pos,
		vector< string >	names = vector<string>()
	)

Check collision with objects.

Parameters

c	the collision data associated with the sprite to check collision with.
cPos	the position of the sprite we want to check collision with.
pos	the current sprite's position.
names	the names that should be checked (empty checks all)

Returns

Returns true if any of the object's collision datas are colliding .

Definition at line 74 of file CollisionObject.cpp.

virtual pair<WorldObject*, CollisionObject*> CollisionObject::collision ( const CollisionObject *  c, WorldObject *  wo, WorldObject *  mObj  ) const

pure virtual

Check collision with objects.

Parameters

c	a single collision data for an object
wo	Pointer to Object with checking bound
mObj	the current collision's world object

Returns

Returns true if any of the object's collision datas are colliding .

Implemented in CollisionSegment, CollisionCircle, and CollisionRectangle.

Here is the caller graph for this function:

virtual void CollisionObject::draw ( const Point2D &  pos )

pure virtual

Draws the collision data to the screen.

Implemented in CollisionSegment, CollisionCircle, and CollisionRectangle.

virtual CollisionObjectType CollisionObject::getType ( ) const

pure virtual

This provides a simple interface to determine types of objects.

Returns the name of the Class and Descendants i.e. Something inheriting from Sprite would look like Sprite:Thing

Implemented in CollisionSegment, CollisionCircle, and CollisionRectangle.
