Member Function Documentation

void Hud::addHealthBar	(	std::shared_ptr< Pawn > const &	pawnToTrack,
		sf::Vector2f const &	offsetOrPosition,
		sf::Vector2f const &	size,
		sf::Texture *	texture = nullptr,
		bool	stationary = false
	)

Adds a healthbar to the hud.

Parameters

pawnToTrack	The pawn whose health will be displayed by the bar.
offsetOrPosition	The offset (for following healthbars) or position (for stationary healthbars) at which to draw the bar. Offset is an offset from the pawn.
size	The size of the bar at full health.
texture	Texture to draw the bar with. If NULL, will default to solid red.
stationary	True if the bar is to be non-moving. (Placed statically on the screen).

Remarks

The pawn's health at time of construction is what the healthbar will consider its max health.

void Hud::addImage	(	sf::Texture &	texture,
		sf::Vector2f const &	position,
		sf::Vector2f const &	scale = {1.f, 1.f}
	)

Adds an image to the hud.

Parameters

texture	Texture to be drawn.
position	Upper left corner of image to be drawn.
scale	Absolute scale of the image, where {1, 1} is original texture size.

void Hud::addLifeTracker	(	std::shared_ptr< int > const &	livesToTrack,
		sf::Texture &	texture,
		sf::Vector2f const &	position,
		sf::Vector2f const &	scale = {1.f, 1.f},
		sf::Vector2f const &	spacing = {0.f, 0.f}
	)

Adds a series of images to the hud. The number of images reflects the value of a shared int.

Parameters

livesToTrack	Shared pointer to the number of images to draw. (e.g. Lives, Deaths, Potions...)
position	The upper left corner of the first image. This is the anchor.
scale	How much to scale the image by. All images will be drawn the same size, this is an overall scale.
spacing	The space between each image. This is measured from the top left of the last image drawn.

void Hud::addNumberTracker	(	std::shared_ptr< int > const &	number,
		sf::Vector2f const &	position,
		sf::Font const &	font,
		unsigned int	charSize = 30u,
		sf::Vector2f const &	scale = {1.f, 1.f}
	)

Adds a number to the hud.

Parameters

number	Shared number to be displayed
position	Location of number of screen (upper left corner).
font	The font to use for the text.
charSize	The character size of the text.
scale	How much the scale the text by.
