Detailed Description

Geometric circle class.

Constructor & Destructor Documentation

Constructor.

Parameters:

centerPosition	Position of the circle's center.
radius	The circle's radius (> 0.f).

virtual sf::Vector2f thor::Circle::GetRandomPoint ( ) const [virtual]

Returns a random point inside the zone (uniformly distributed).

Returns:: Point in global coordinate system (translation, rotation already applied).

Implements thor::Zone.

sf::Vector2f thor::Zone::TransformToGlobal ( sf::Vector2f point ) const [protected, inherited]

Transforms a point according to the position and rotation of the zone.

Parameters:

point Point in unit coordinate system with origin (0, 0).

Returns:: Point in a coordinate system rotated by the zone's rotation and offset by the zone's position (in this order).
