Member Function Documentation

◆ initBackend()

virtual void OSystem_Dreamcast::initBackend ( )

virtual

The following method is called once, from main.cpp, after all config data (including command line params etc.) is fully loaded.

Note: Subclasses should always invoke the implementation of their parent class. They should do so near the end of their own implementation.

Reimplemented from EventsBaseBackend.

◆ hasFeature()

bool OSystem_Dreamcast::hasFeature ( Feature f )

virtual

Determine whether the backend supports the specified feature.

Reimplemented from OSystem.

◆ setFeatureState()

void OSystem_Dreamcast::setFeatureState	(	Feature	f,
		bool	enable
	)

virtual

Enable or disable the specified feature.

For example, this may be used to enable fullscreen mode or to deactivate aspect correction, etc.

Reimplemented from OSystem.

◆ getFeatureState()

bool OSystem_Dreamcast::getFeatureState ( Feature f )

virtual

Query the state of the specified feature.

For example, test whether fullscreen mode is active or not.

Reimplemented from OSystem.

◆ getPaletteManager()

PaletteManager* OSystem_Dreamcast::getPaletteManager ( )

inlinevirtual

Return the palette manager singleton.

For more information, see PaletteManager.

Implements OSystem.

◆ setPalette()

void OSystem_Dreamcast::setPalette	(	const byte *	colors,
		uint	start,
		uint	num
	)

protectedvirtual

Replace the specified range of the palette with new colors. The palette entries from 'start' till (start+num-1) will be replaced - so a full palette update is accomplished via start=0, num=256.

The palette data is specified in interleaved RGB format. That is, the first byte of the memory block 'colors' points at is the red component of the first new color; the second byte the green component of the first new color; the third byte the blue component, the last byte to the alpha (transparency) value. Then the second color starts, and so on. So memory looks like this: R1-G1-B1-R2-G2-B2-R3-...

Parameters

colors	the new palette data, in interleaved RGB format
start	the first palette entry to be updated
num	the number of palette entries to be updated

Note: It is an error if start+num exceeds 256, behavior is undefined in that case (the backend may ignore it silently or assert).; It is an error if this function gets called when the pixel format in use (the return value of getScreenFormat) has more than one byte per pixel.

See also: getScreenFormat

Implements PaletteManager.

◆ grabPalette()

void OSystem_Dreamcast::grabPalette	(	byte *	colors,
		uint	start,
		uint	num
	)		const

protectedvirtual

Grabs a specified part of the currently active palette. The format is the same as for setPalette.

This should return exactly the same RGB data as was setup via previous setPalette calls.

For example, for every valid value of start and num of the following code:

byte origPal[num*3]; // Setup origPal's data however you like g_system->setPalette(origPal, start, num); byte obtainedPal[num*3]; g_system->grabPalette(obtainedPal, start, num);

the following should be true:

memcmp(origPal, obtainedPal, num*3) == 0

See also: setPalette

Parameters

colors	the palette data, in interleaved RGB format
start	the first platte entry to be read
num	the number of palette entries to be read

Note: It is an error if this function gets called when the pixel format in use (the return value of getScreenFormat) has more than one byte per pixel.

See also: getScreenFormat

Implements PaletteManager.

◆ initSize()

void OSystem_Dreamcast::initSize	(	uint	width,
		uint	height,
		const Graphics::PixelFormat *	format
	)

virtual

Set the size and color format of the virtual screen.

Typical sizes include:

320x200 (e.g. for most SCUMM games, and Simon)
320x240 (e.g. for FM-TOWN SCUMM games)
640x480 (e.g. for Curse of Monkey Island)

This is the resolution for which the client code generates data. This is not necessarily equal to the actual display size. For example, a backend may magnify the graphics to fit on the screen (see also the GraphicsMode), stretch the data to perform aspect ratio correction, or shrink it to fit on small screens (in cell phones).

Typical formats include:

CLUT8 (e.g. 256 color, for most games)
RGB555 (e.g. 16-bit color, for later SCUMM HE games)
RGB565 (e.g. 16-bit color, for Urban Runner)

This is the pixel format for which the client code generates data. It is not necessarily equal to the hardware pixel format. For example, a backend may perform color lookup of 8-bit graphics before pushing a screen to hardware, or correct the ARGB color order.

Parameters

width	New virtual screen width.
height	New virtual screen height.
format	New virtual screen pixel format.

Implements OSystem.

◆ getHeight()

int16 OSystem_Dreamcast::getHeight ( )

inlinevirtual

Return the currently set virtual screen height.

See also: initSize

Returns: Currently set virtual screen height.

Implements OSystem.

◆ getWidth()

int16 OSystem_Dreamcast::getWidth ( )

inlinevirtual

Return the currently set virtual screen width.

See also: initSize

Returns: Currently set virtual screen width.

Implements OSystem.

◆ copyRectToScreen()

void OSystem_Dreamcast::copyRectToScreen	(	const void *	buf,
		int	pitch,
		int	x,
		int	y,
		int	w,
		int	h
	)

virtual

Blit a bitmap to the virtual screen.

The real screen will not immediately be updated to reflect the changes. Client code must call updateScreen to ensure any changes are visible to the user. This can be used to optimize drawing and reduce flicker.

If the current pixel format has one byte per pixel, the graphics data uses 8 bits per pixel, using the palette specified via setPalette. If more than one byte per pixel is in use, the graphics data uses the pixel format returned by getScreenFormat.

Parameters

buf	Buffer containing the graphics data source.
pitch	Pitch of the buffer (number of bytes in a scanline).
x	x coordinate of the destination rectangle.
y	y coordinate of the destination rectangle.
w	Width of the destination rectangle.
h	Height of the destination rectangle.

Note: The specified destination rectangle must be completly contained in the visible screen space, and must be non-empty. If not, a backend may or may not perform clipping, trigger an assert, or silently corrupt memory.

See also: updateScreen; getScreenFormat

Implements OSystem.

◆ lockScreen()

virtual Graphics::Surface* OSystem_Dreamcast::lockScreen ( )

virtual

Lock the active screen framebuffer and return a Graphics::Surface representing it.

The caller can then perform arbitrary graphics transformations on the framebuffer (blitting, scrolling, etc.). Must be followed by a matching call to unlockScreen(). Code that is calling this should make sure to only lock the framebuffer for the shortest time possible, as the whole system is potentially stalled while the lock is active.

Returns: 0 if an error occurs. Otherwise, a surface with the pixel format described by getScreenFormat is returned.

The returned surface must not be deleted by the client code.

See also: getScreenFormat

Implements OSystem.

◆ unlockScreen()

virtual void OSystem_Dreamcast::unlockScreen ( )

virtual

Unlock the screen framebuffer, and mark it as dirty, i.e. during the next updateScreen() call, the whole screen will be updated.

Implements OSystem.

◆ updateScreen()

void OSystem_Dreamcast::updateScreen ( )

virtual

Flush the whole screen, i.e. render the current content of the screen framebuffer to the display.

This method may be called very often by engines. Backends are hence supposed to only perform any redrawing if it is necessary and otherwise return immediately. See https://wiki.scummvm.org/index.php/HOWTO-Backends#updateScreen.28.29_method

Implements OSystem.

◆ showMouse()

bool OSystem_Dreamcast::showMouse ( bool visible )

virtual

Show or hide the mouse cursor.

Currently, the backend is not required to immediately draw the mouse cursor on showMouse(true).

See also: Graphics::CursorManager::showMouse

Implements OSystem.

◆ warpMouse()

void OSystem_Dreamcast::warpMouse	(	int	x,
		int	y
	)

virtual

Move ("warp") the mouse cursor to the specified position in virtual screen coordinates.

Parameters

x	New x position of the mouse.
y	New y position of the mouse.

Implements OSystem.

◆ setMouseCursor()

void OSystem_Dreamcast::setMouseCursor	(	const void *	buf,
		uint	w,
		uint	h,
		int	hotspotX,
		int	hotspotY,
		uint32	keycolor,
		bool	dontScale,
		const Graphics::PixelFormat *	format,
		const byte *	mask
	)

virtual

Set the bitmap used for drawing the cursor.

Parameters

buf	Pixmap data to be used.
w	Width of the mouse cursor.
h	Height of the mouse cursor.
hotspotX	Horizontal offset from the left side to the hotspot.
hotspotY	Vertical offset from the top side to the hotspot.
keycolor	Transparency color value. This should not exceed the maximum color value of the specified format. In case it does, the behavior is undefined. The backend might just error out or simply ignore the value. (The SDL backend will just assert to prevent abuse of this). This parameter does nothing if a mask is provided.
dontScale	Whether the cursor should never be scaled. An exception is high ppi displays, where the cursor might be too small to notice otherwise, these are allowed to scale the cursor anyway.
format	Pointer to the pixel format that the cursor graphic uses (0 means CLUT8).
mask	A mask containing values from the CursorMaskValue enum for each cursor pixel.

Implements OSystem.

◆ setCursorPalette()

void OSystem_Dreamcast::setCursorPalette	(	const byte *	colors,
		uint	start,
		uint	num
	)

virtual

Replace the specified range of cursor palette with new colors.

The palette entries from 'start' till (start+num-1) will be replaced - so a full palette update is accomplished via start=0, num=256.

Backends which implement this should have the kFeatureCursorPalette flag set.

See also: setPalette; kFeatureCursorPalette

Reimplemented from OSystem.

◆ setShakePos()

void OSystem_Dreamcast::setShakePos	(	int	shakeXOffset,
		int	shakeYOffset
	)

virtual

Set current shake position, a feature needed for screen effects in some engines.

The effect causes the displayed graphics to be shifted downwards and rightwards by the specified offsets (the offsets can be negative to shift upwards or leftwards). The area at the border of the screen which is moved into view by this (for example at the bottom when moving upward) is filled with black. This does not cause any graphic data to be lost. To restore the original view, the game engine only has to call this method again with offset equal to zero. No calls to copyRectToScreen are necessary.

Parameters

shakeXOffset	Shake x offset.
shakeYOffset	Shake y offset.

Note: This is currently used in the SCUMM, QUEEN, KYRA, SCI, DREAMWEB, SUPERNOVA, TEENAGENT, TOLTECS, ULTIMA, and PETKA engines.

Implements OSystem.

◆ getMillis()

uint32 OSystem_Dreamcast::getMillis ( bool skipRecord = false )

virtual

Get the number of milliseconds since the program was started.

Parameters

skipRecord Skip recording of this value by the event recorder. This might be needed particularly when we are in an on-screen GUI loop where the player can pause the recording.

Implements OSystem.

◆ delayMillis()

void OSystem_Dreamcast::delayMillis ( uint msecs )

virtual

Delay/sleep for the specified amount of milliseconds.

Implements OSystem.

◆ getTimeAndDate()

void OSystem_Dreamcast::getTimeAndDate	(	TimeDate &	td,
		bool	skipRecord = `false`
	)		const

virtual

Get the current time and date, in the local timezone.

On many systems, this corresponds to the combination of time() and localtime().

Implements OSystem.

◆ pollEvent()

bool OSystem_Dreamcast::pollEvent ( Common::Event & event )

virtual

Query an event from the source.

Parameters

event Reference to the event struct where the event should be stored.

Return values

true	If an event was polled, false otherwise.

Implements Common::EventSource.

◆ quit()

void OSystem_Dreamcast::quit ( )

virtual

Quit (exit) the application.

Implements OSystem.

◆ getOverlayHeight()

int16 OSystem_Dreamcast::getOverlayHeight ( )

virtual

Return the height of the overlay.

See also: getHeight

Implements OSystem.

◆ getOverlayWidth()

int16 OSystem_Dreamcast::getOverlayWidth ( )

virtual

Return the width of the overlay.

See also: getWidth

Implements OSystem.

◆ isOverlayVisible()

bool OSystem_Dreamcast::isOverlayVisible ( ) const

inlinevirtual

Return true if the overlay mode is activated, false otherwise.

Implements OSystem.

◆ showOverlay()

void OSystem_Dreamcast::showOverlay ( bool inGUI )

virtual

Activate the overlay mode.

Implements OSystem.

◆ hideOverlay()

void OSystem_Dreamcast::hideOverlay ( )

virtual

Deactivate the overlay mode.

Implements OSystem.

◆ clearOverlay()

void OSystem_Dreamcast::clearOverlay ( )

virtual

Reset the overlay.

After calling this method while the overlay mode is active, the user should be seeing only the game graphics. How this is achieved depends on how the backend implements the overlay. It either sets all pixels of the overlay to be transparent (when alpha blending is used) or, in case of fake alpha blending, it might just put a copy of the current game graphics screen into the overlay.

Implements OSystem.

◆ grabOverlay()

void OSystem_Dreamcast::grabOverlay ( Graphics::Surface & surface )

virtual

Copy the content of the overlay into a surface provided by the caller.

This is only used to implement fake alpha blending.

Implements OSystem.

◆ copyRectToOverlay()

void OSystem_Dreamcast::copyRectToOverlay	(	const void *	buf,
		int	pitch,
		int	x,
		int	y,
		int	w,
		int	h
	)

virtual

Blit a graphics buffer to the overlay.

In a sense, this is the reverse of grabOverlay.

Parameters

buf	Buffer containing the graphics data source.
pitch	Pitch of the buffer (number of bytes in a scanline).
x	x coordinate of the destination rectangle.
y	y coordinate of the destination rectangle.
w	Width of the destination rectangle.
h	Height of the destination rectangle.

See also: copyRectToScreen; grabOverlay

Implements OSystem.

◆ getOverlayFormat()

virtual Graphics::PixelFormat OSystem_Dreamcast::getOverlayFormat ( ) const

inlinevirtual

Return the pixel format description of the overlay.

See also: Graphics::PixelFormat

Implements OSystem.

◆ createMutex()

Common::MutexInternal* OSystem_Dreamcast::createMutex ( )

virtual

Create a new mutex.

Returns: The newly created mutex, or 0 if an error occurred.

Implements OSystem.

◆ setWindowCaption()

void OSystem_Dreamcast::setWindowCaption ( const Common::U32String & caption )

virtual

Set a window caption or any other comparable status display to the given value.

Parameters

caption The window caption to use.

Reimplemented from OSystem.

◆ getMixer()

Audio::Mixer* OSystem_Dreamcast::getMixer ( )

inlinevirtual

Return the audio mixer.

For more information, see Audio::Mixer.

Implements OSystem.

◆ makeRootFileNode()

AbstractFSNode* OSystem_Dreamcast::makeRootFileNode ( ) const

overridevirtual

Returns a special node representing the filesystem root. The starting point for any file system browsing.

On Unix, this will be simply the node for / (the root directory). On Windows, it will be a special node which "contains" all drives (C:, D:, E:).

Implements FilesystemFactory.

◆ makeCurrentDirectoryFileNode()

AbstractFSNode* OSystem_Dreamcast::makeCurrentDirectoryFileNode ( ) const

overridevirtual

Returns a node representing the "current directory". If your system does not support this concept, you can either try to emulate it or simply return some "sensible" default directory node, e.g. the same value as getRoot() returns.

Implements FilesystemFactory.

◆ makeFileNodePath()

AbstractFSNode* OSystem_Dreamcast::makeFileNodePath ( const Common::String & path ) const

overridevirtual

Construct a node based on a path; the path is in the same format as it would be for calls to fopen().

Furthermore getNodeForPath(oldNode.path()) should create a new node identical to oldNode. Hence, we can use the "path" value for persistent storage e.g. in the config file.

Parameters

path	The path string to create a FSNode for.

Implements FilesystemFactory.
