TextCamera

public TextCamera()

Method Detail

renderBackBuffer

public void renderBackBuffer()

Render the entire view to the offscreen buffer.

Specified by:

renderBackBuffer in interface Camera

Specified by:

renderBackBuffer in class CameraBase

visibleThing

protected Thing visibleThing(RLPoint p)

A thing is visible if it is the highest priority known thing at a particular location. Priorities: 1. under the pointer 2. creature 3. item 4. terrain

Specified by:

visibleThing in class CameraBase

render

protected void render(Thing t,
                      java.awt.Graphics g,
                      double x,
                      double y,
                      int ox,
                      int oy)

Render t as if it was located at (x,y) on the Board. Note that although actual Board locations are always integral, Things may be drawn at fractional locations for smooth animation capabilities.

createImage

protected java.awt.image.BufferedImage createImage(Thing t)

Create and return an image representation of this Thing. This need not represent the final appearance; for instance, the image returned by this implementation does not include creature health bars or the highlighter.

renderSprite

public void renderSprite(Thing t,
                         double x,
                         double y)

Draw t above the current image immediately.

Specified by:

renderSprite in interface Camera

Specified by:

renderSprite in class CameraBase

restoreBackBuffer

public void restoreBackBuffer(double x,
                              double y,
                              double w,
                              double h)

Copy the contents of the back buffer to the screen. This method is useful for erasing sprites.

Specified by:

restoreBackBuffer in interface Camera

Specified by:

restoreBackBuffer in class CameraBase

regionChange

public void regionChange(ChangeEvent event)

Respond to a change in Board region coverage.

Specified by:

regionChange in interface CameraModelListener

Overrides:

regionChange in class CameraBase

boardChange

public void boardChange(ChangeEvent event)

Respond to a change in underlying Board.

Specified by:

boardChange in interface CameraModelListener

Overrides:

boardChange in class CameraBase

visualChange

public void visualChange(Thing t)

Respond to an indication that the appearance of a Thing has changed.

Specified by:

visualChange in interface CameraModelListener

Overrides:

visualChange in class CameraBase

loadResources

protected void loadResources()

setModel

public void setModel(CameraModel model)

Set the model.

Specified by:

setModel in interface Camera

Overrides:

setModel in class CameraBase

update

public void update(int x,
                   int y,
                   int width,
                   int height)

Figure out what should be drawn in a region.

Specified by:

update in interface Camera

Specified by:

update in class CameraBase

flush

public void flush()

Copy the back buffer to the screen. Note that this method can have undesirable effects if it is called when the overlay is visible; the camera contents will be drawn over the overlay! Instead, because when the overlay is visible, performance is probably not a concern, updates should be accomplished by calling component.repaint().

Specified by:

flush in interface Camera

Overrides:

flush in class CameraBase

createFontHelpers

protected void createFontHelpers()
