Member Function Documentation

drawBitmapToBackground()

void StarTrek::Graphics::drawBitmapToBackground	(	const Common::Rect &	origRect,
		const Common::Rect &	drawRect,
		Bitmap *	bitmap
	)

Parameters

origRect	The rectangle containing the original bitmap (must contain the whole bitmap, even if some is outside the drawable space)
drawRect	The clipped rectangle to draw at (must be within the drawable space)

loadPalette()

void StarTrek::Graphics::loadPalette

(

const String &

paletteFile

)

Note: this doesn't flush the palette to the screen (must call "setPaletteFadeLevel")

setPaletteFadeLevel()

void StarTrek::Graphics::setPaletteFadeLevel	(	byte *	palData,
		int	fadeLevel
	)

This flushes the palette to the screen. fadeLevel ranges from 0-100.

setMouseBitmap()

void StarTrek::Graphics::setMouseBitmap

(

Common::String

bitmapName

)

Changes the mouse bitmap. The change won't take effect until drawAllSprites is called again.

lockMousePosition()

void StarTrek::Graphics::lockMousePosition	(	int16	x,
		int16	y
	)

This function is a workaround for when the mouse position needs to be locked in a set position (used in the action menu). This only affects the position it is drawn at; the sprite's "real" position is still updated normally.

This does not call updateScreen.

drawSprite()

void StarTrek::Graphics::drawSprite	(	const Sprite &	sprite,
		::Graphics::Surface *	surface,
		const Common::Rect &	rect,
		int	rectLeft = 0,
		int	rectTop = 0
	)

Parameters

sprite	The sprite to draw
surface	The surface to draw to
rect	The part of the sprite to draw (only draw the part of the sprite that intersects with it) @
rectLeft	X-offset to subtract before drawing to surface. @
rectTop	Y-offset to subtract before drawing to surface.

drawAllSpritesInRectToSurface()

void StarTrek::Graphics::drawAllSpritesInRectToSurface	(	const Common::Rect &	rect,
		::Graphics::Surface *	surface
	)

This function should only be called after "drawAllSprites" (so that sprite rects are updated).

forceDrawAllSprites()

void StarTrek::Graphics::forceDrawAllSprites

(

bool

updateScreenFlag = true

)

Sets "bitmapChanged" to true on all sprites before calling drawAllSprites.

updateScreen()

void StarTrek::Graphics::updateScreen

(

)

Flushes the screen. Usually called by "drawAllSprites".

getSpriteAt()

Sprite* StarTrek::Graphics::getSpriteAt	(	int16	x,
		int16	y
	)

Returns the sprite at the given position (ignores mouse).
