Member Function Documentation

clear()

void Ultima::Ultima4::Screen::clear

(

)

Reset the screen

setMouseCursor()

void Ultima::Ultima4::Screen::setMouseCursor

(

MouseCursor

cursor

)

Sets a given mouse cursor

screenReInit()

void Ultima::Ultima4::Screen::screenReInit

(

)

Re-initializes the screen and implements any changes made in settings

screenDrawImage()

void Ultima::Ultima4::Screen::screenDrawImage	(	const Common::String &	name,
		int	x = 0,
		int	y = 0
	)

Draw an image or subimage on the screen.

screenScrollMessageArea()

void Ultima::Ultima4::Screen::screenScrollMessageArea

(

)

Scroll the text in the message area up one position.

screenShake()

void Ultima::Ultima4::Screen::screenShake

(

int

iterations

)

Do the tremor spell effect where the screen shakes.

screenShowChar()

void Ultima::Ultima4::Screen::screenShowChar	(	int	chr,
		int	x,
		int	y
	)

Draw a character from the charset onto the screen.

screenTextColor()

void Ultima::Ultima4::Screen::screenTextColor

(

int

color

)

Change the current text color

screenUpdate()

void Ultima::Ultima4::Screen::screenUpdate	(	TileView *	view,
		bool	showmap,
		bool	blackout
	)

Redraw the screen. If showmap is set, the normal map is drawn in the map area. If blackout is set, the map area is blacked out. If neither is set, the map area is left untouched.

screenPointInMouseArea()

int Ultima::Ultima4::Screen::screenPointInMouseArea	(	int	x,
		int	y,
		const MouseArea *	area
	)

Determine if the given point is within a mouse area.

screenScale()

Image* Ultima::Ultima4::Screen::screenScale	(	Image *	src,
		int	scale,
		int	n,
		int	filter
	)

Scale an image up. The resulting image will be scale * the original dimensions. The original image is no longer deleted. n is the number of tiles in the image; each tile is filtered separately. filter determines whether or not to filter the resulting image.

screenScaleDown()

Image* Ultima::Ultima4::Screen::screenScaleDown	(	Image *	src,
		int	scale
	)

Scale an image down. The resulting image will be 1/scale * the original dimensions. The original image is no longer deleted.
