Protected Member Functions | |
| Zone (sf::Vector2f position, float rotation) | |
| Base class constructor. | |
| sf::Vector2f | TransformToGlobal (sf::Vector2f point) const |

Abstract base class for geometric zones.
A zone represents an geometric figure on the screen, e.g. a rectangle, circle or just a point. Derive from this class to implement your own zone.
| virtual sf::Vector2f thor::Zone::GetRandomPoint | ( | ) | const [pure virtual] |
Returns a random point inside the zone (uniformly distributed).
Implemented in thor::Rectangle, thor::Circle, and thor::Point.
| sf::Vector2f thor::Zone::TransformToGlobal | ( | sf::Vector2f | point | ) | const [protected] |
Transforms a point according to the position and rotation of the zone.
| point | Point in unit coordinate system with origin (0, 0). |
