public class MainDisplay

extends JPanel

This class is the panel on which the action part of the game is rendered. At
each tick, this panel is repainted with the contents of the screen that is in
the location for the local player as returned by GameSetup.getLocalPlayer.
This uses the scrolling, scaling, and optimize options specified by GameSetup.
The only method that should really be used from the outside is getClickLocation.
You could also call setForceDraw, but that can also be achieved by turning the
draw optimization off for one tick in the GameSetup.

Constructor Summary

MainDisplay(MainFrame mf)           This mainly figures out what size this panel should "prefer" to be.

Method Summary
void	draw(Player player)           Draw the display assuming the player passed in.
Location	getClickLocation(int x, int y)           This function does a conversion from display coordinates to the locations coordinates in the screen that it is displaying.
int	getDrawX(Location loc)           This function tells you the physical display x for a given location on the screen.
int	getDrawY(Location loc)           This function tells you the physical display y for a given location on the screen.
Dimension	getPreferredSize()           Returns the size that this display would be without any scaling for the drawing options it was first set up to use.
void	paintComponent(Graphics g)           Renders the image drawn by the draw method to the provided Graphics object.
void	setForceDraw()           Tell the display that at the next draw call (typically the next tick) that it must redraw all of the blocks for the background and can't use a buffered image.

public MainDisplay(MainFrame mf)

This mainly figures out what size this panel should "prefer" to be.

public void draw(Player player)

Draw the display assuming the player passed in.

Parameters:

player This is the player whose location is used for the drawing.

public Location getClickLocation(int x, int y)

This function does a conversion from display coordinates to the locations
coordinates in the screen that it is displaying. When you get a MouseEvent
you can pass the getX() and getY() values from it into this and it will
return the Location of the click.

Parameters:

x The physical display x location.

y The physical display y location.

Returns: The location that corresponds to the physical location that was passed in.

public int getDrawX(Location loc)

This function tells you the physical display x for a given location on
the screen. This is used for drawing and shouldn't need to be called from
external code.

Parameters:

loc The Location you are interested in.

Returns: The x physical display position for that location.

public int getDrawY(Location loc)

This function tells you the physical display y for a given location on
the screen. This is used for drawing and shouldn't need to be called from
external code.

Parameters:

loc The Location you are interested in.

Returns: The y physical display position for that location.

public Dimension getPreferredSize()

Returns the size that this display would be without any scaling for the
drawing options it was first set up to use. This is used by the GUI.

Returns: The size that this "wants" to be so there isn't scaling.

public void paintComponent(Graphics g)

Renders the image drawn by the draw method to the provided Graphics object.
This is automatically called by the GUI framework and should generally
not be called by user code.

Parameters:

g The graphics object to render to.

public void setForceDraw()

Tell the display that at the next draw call (typically the next tick) that
it must redraw all of the blocks for the background and can't use a
buffered image.
