Constructor & Destructor Documentation

Camera()

Camera::Camera ( Camera & other )

delete

Singletons should not be cloneable or assignable.

Member Function Documentation

getInstance()

Camera & Camera::getInstance ( )

staticnodiscard

Returns an instance of the Camera class.

Returns

Camera instance

getTileHeight()

float Camera::getTileHeight ( ) const

nodiscard

Returns the height of a tile according to the current scaling factors.

Returns

Height of a tile

getTileWidth()

float Camera::getTileWidth ( ) const

nodiscard

Returns the width of a tile according to the current scaling factors.

Returns

Width of a tile

operator=()

void Camera::operator= ( const Camera & )

delete

resized()

void Camera::resized

(

)

Update the Camera scaling factors based on the current window size.

When the window is resized it is important that this is properly reflected by the Camera. Will call setScaling afterward.

setScaling()

void Camera::setScaling	(	float	mapWidth,
		float	mapHeight )

Update the Camera scaling factors based on the current world.

This must be done to assure that the whole world will always fit on screen. Regardless of map or window size.

Parameters

mapWidth	The loaded world map width in tiles
mapHeight	The loaded world map height in tiles

xToPixel()

float Camera::xToPixel ( float normalizedX ) const

nodiscard

Parameters

normalizedX

Normalized world X coordinate.

Returns

X coordinate scaled appropriately for the current window width.

yToPixel()

float Camera::yToPixel ( float normalizedY ) const

nodiscard

Parameters

normalizedY

Normalized world Y coordinate.

Returns

Y coordinate scaled appropriately for the current window height.
