                         int w,
                         int h,
                         Camera c)

Builds a new portal displaying what is seen through a camera

Parameters:

x - top-left horizontal coordinate of portal, in parent's JPanel coordinates

y - top-left vertical coordinate of portal, in parent's JPanel coordinates

w - portal width

h - portal height

c - camera associated with the portal

                         float a)

Builds a new portal displaying what is seen through a camera

Parameters:

x - top-left horizontal coordinate of portal, in parent's JPanel coordinates

y - top-left vertical coordinate of portal, in parent's JPanel coordinates

w - portal width

h - portal height

c - camera associated with the portal

a - alpha channel value (translucency). alpha ranges between 0.0 (fully transparent) and 1.0 (fully opaque)

Method Detail

getVisibleRegion

public double[] getVisibleRegion()

Get bounds of rectangular region of the VirtualSpace seen through this camera portal. Although the region seen is actually an oval, we approximate it to the bounding rectangle.

Overrides:

getVisibleRegion in class CameraPortal

Returns:

boundaries in VirtualSpace coordinates {west,north,east,south}

coordInside

public boolean coordInside(int cx,
                           int cy)

Description copied from class: Portal

detects whether the given point is inside this portal or not

Overrides:

coordInside in class CameraPortal

Parameters:

cx - cursor x-coordinate (JPanel coordinates system)

cy - cursor y-coordinate (JPanel coordinates system)

coordInsideBorder

public boolean coordInsideBorder(int cx,
                                 int cy)

Overrides:

coordInsideBorder in class CameraPortal

move

public void move(int dx,
                 int dy)

Move the portal inside the view (relative).

Overrides:

move in class Portal

Parameters:

dx - x-offset (JPanel coordinates system)

dy - y-offset (JPanel coordinates system)

moveTo

public void moveTo(int x,
                   int y)

Move the portal inside the view (absolute).

Overrides:

moveTo in class Portal

Parameters:

x - new x-coordinate (JPanel coordinates system)

y - new y-coordinate (JPanel coordinates system)

updateDimensions

public void updateDimensions()

Overrides:

updateDimensions in class Portal

setBorderWidth

public void setBorderWidth(float w)

Description copied from class: CameraPortal

Set the border width of the portal (use SetBorder to draw the border)

Overrides:

setBorderWidth in class CameraPortal

Parameters:

w - portal border width

paint

public void paint(Graphics2D g2d,
                  int viewWidth,
                  int viewHeight)

Overrides:

paint in class CameraPortal
