Detailed Description

Follow camera that can target an Actor.

Member Function Documentation

void Camera::doMouseMove ( sf::Vector2f mousePos )

Moves the camera if the mouse is close to the screen edge. Assumes that the mouse position is NOT translated from screen to game coordinates.

Parameters

mousePos The position of the mouse

sf::Vector2f Camera::getDisplacement ( ) const

Gets the top left corner of the camera.

void Camera::update ( float deltaSeconds )

Updates camera's center to where the target is. Clamps camera edges to stay inside of bounding area.
