C# Class flxSharp.flxSharp.FlxCamera

The camera class is used to display the game's visuals in the Flash player. By default one camera is created automatically, that is the same size as the Flash player. You can add more cameras or even replace the main camera using utilities in FlxG.

Public Methods

Method	Description
Fade ( Color color, float duration = 1, System.Action onComplete = null, bool force = false ) : void	The screen is gradually filled with this color.
Fill ( Color color, bool blendAlpha = true ) : void	Fill the camera with the specified color.
Flash ( Color color, float duration = 1, System.Action onComplete = null, bool force = false ) : void	The screen is filled with this color and gradually returns to normal.
FlxCamera ( float x, float y, int width, int height, float zoom ) : System	Instantiates a new camera at the specified location, with the specified size and zoom level.
copyFrom ( FlxCamera camera ) : FlxCamera	Copy the bounds, focus object, and deadzone info from an existing camera.
destroy ( ) : void	Clean up memory.
focusOn ( FlxPoint point ) : void	Move the camera focus to this location instantly.
follow ( FlxObject target, uint style = StyleLockon ) : void	Tells this camera object what `FlxObject` to track.
getContainerSprite ( ) : object	Fetches a reference to the Flash `Sprite` object that contains the camera display in the Flash display list. Uses include 3D projection, advanced display list modification, and more. NOTE: We don't recommend modifying this directly unless you are fairly experienced. For simple changes to the camera display, like scaling, rotation, and color tinting, we recommend using the existing `FlxCamera` variables.
setBounds ( float x, float y, float width, float height, System.Boolean updateWorld = false ) : void	Specify the boundaries of the level or where the camera is allowed to move.
shake ( float intensity = 0.05f, float duration = 0.5f, System.Action onComplete = null, bool force = true, uint direction = ShakeBothAxes ) : void	A simple screen-shake effect.
stopFX ( ) : void	Just turns off all the camera effects instantly.
update ( ) : void	Updates the camera scroll as well as special effects like screen-shake or fades.

Method Details

Fade() public method

The screen is gradually filled with this color.

public Fade ( Color color, float duration = 1, System.Action onComplete = null, bool force = false ) : void
color	Color	The color you want to use.
duration	float	How long it takes for the fade to finish.
onComplete	System.Action	A function you want to run when the fade finishes.
force	bool	Force the effect to reset.
return	void

Fill() public method

Fill the camera with the specified color.

public Fill ( Color color, bool blendAlpha = true ) : void
color	Color	The color to fill with in 0xAARRGGBB hex format.
blendAlpha	bool	Whether to blend the alpha value or just wipe the previous contents. Default is true.
return	void

Flash() public method

The screen is filled with this color and gradually returns to normal.

public Flash ( Color color, float duration = 1, System.Action onComplete = null, bool force = false ) : void
color	Color	The color you want to use.
duration	float	How long it takes for the flash to fade.
onComplete	System.Action	A function you want to run when the flash finishes.
force	bool	Force the effect to reset.
return	void

FlxCamera() public method

Instantiates a new camera at the specified location, with the specified size and zoom level.

public FlxCamera ( float x, float y, int width, int height, float zoom ) : System
x	float	X location of the camera's display in pixels. Uses native, 1:1 resolution, ignores zoom.
y	float	Y location of the camera's display in pixels. Uses native, 1:1 resolution, ignores zoom.
width	int	The width of the camera display in pixels.
height	int	The height of the camera display in pixels.
zoom	float	The initial zoom level of the camera. A zoom level of 2 will make all pixels display at 2x resolution.
return	System

copyFrom() public method

Copy the bounds, focus object, and deadzone info from an existing camera.

public copyFrom ( FlxCamera camera ) : FlxCamera
camera	FlxCamera	The camera you want to copy from.
return	FlxCamera

destroy() public method

Clean up memory.

public destroy ( ) : void
return	void

focusOn() public method

Move the camera focus to this location instantly.

public focusOn ( FlxPoint point ) : void
point	FlxPoint	Where you want the camera to focus.
return	void

follow() public method

Tells this camera object what FlxObject to track.

public follow ( FlxObject target, uint style = StyleLockon ) : void
target	FlxObject	The object you want the camera to track. Set to null to not follow anything.
style	uint	Leverage one of the existing "deadzone" presets. If you use a custom deadzone, ignore this parameter and manually specify the deadzone after calling `follow()`.
return	void

getContainerSprite() public method

Fetches a reference to the Flash Sprite object that contains the camera display in the Flash display list. Uses include 3D projection, advanced display list modification, and more. NOTE: We don't recommend modifying this directly unless you are fairly experienced. For simple changes to the camera display, like scaling, rotation, and color tinting, we recommend using the existing FlxCamera variables.

public getContainerSprite ( ) : object
return	object

setBounds() public method

Specify the boundaries of the level or where the camera is allowed to move.

public setBounds ( float x, float y, float width, float height, System.Boolean updateWorld = false ) : void
x	float	The smallest X value of your level (usually 0).
y	float	The smallest Y value of your level (usually 0).
width	float	The largest X value of your level (usually the level width).
height	float	The largest Y value of your level (usually the level height).
updateWorld	System.Boolean	Whether the global quad-tree's dimensions should be updated to match (default: false).
return	void

shake() public method

A simple screen-shake effect.

public shake ( float intensity = 0.05f, float duration = 0.5f, System.Action onComplete = null, bool force = true, uint direction = ShakeBothAxes ) : void
intensity	float	Percentage of screen size representing the maximum distance that the screen can move while shaking.
duration	float	The length in seconds that the shaking effect should last.
onComplete	System.Action	A function you want to run when the shake effect finishes.
force	bool	Force the effect to reset (default = true, unlike flash() and fade()!).
direction	uint	Whether to shake on both axes, just up and down, or just side to side (use class constants SHAKE_BOTH_AXES, SHAKE_VERTICAL_ONLY, or SHAKE_HORIZONTAL_ONLY).
return	void

stopFX() public method

Just turns off all the camera effects instantly.

public stopFX ( ) : void
return	void

update() public method

Property Details

BgColor public_oe property

The natural background color of the camera. Defaults to FlxG.bgColor. NOTE: can be transparent for crazy FX!

public Color BgColor
return	Color

Bounds public_oe property

The edges of the camera's range, i.e. where to stop scrolling. Measured in game pixels and world coordinates.

public FlxRect,flxSharp.flxSharp Bounds
return	FlxRect

Buffer public_oe property

The actual bitmap data of the camera display itself.

public RenderTarget2D,Microsoft.Xna.Framework.Graphics Buffer

Deadzone public_oe property

You can assign a "dead zone" to the camera in order to better control its movement. The camera will always keep the focus object inside the dead zone, unless it is bumping up against the bounds rectangle's edges. The deadzone's coordinates are measured from the camera's upper left corner in game pixels. For rapid prototyping, you can use the preset deadzones (e.g. STYLE_PLATFORMER) with follow().

public FlxRect,flxSharp.flxSharp Deadzone
return	FlxRect
