Constructor Detail

DisplayHandler

public DisplayHandler()

Method Detail

getRenderFrame

public int getRenderFrame()

Get the number of the frame that is being rendered.

Returns:

frame number

setSize

public void setSize(int w,
                    int h)

Sets the size of the viewport (JPanel/GLCanvas).

Parameters:

w - width

h - height

setMouseListeners

public void setMouseListeners(java.awt.event.MouseListener m1,
                              java.awt.event.MouseMotionListener m2)

Sets camera-tracking mouse action handlers. It is recommended that both listeners be implemented in the same class and the same object be passed in twice.

Parameters:

m1 - the MouseListener.

m2 - the MouseMotionListener.

getPreferredSize

public java.awt.Dimension getPreferredSize()

Gets the viewport's hard-coded preferred size.

Returns:

the display's preferred size.

add

public void add(Drawable entity)

Adds a Drawable to the handler. Its draw() method will be called every update.

Parameters:

entity - the Drawable to add.

add

public void add(ParticleManager p)

Sets the display's ParticleManager.

Parameters:

p - the ParticleManager to use.

init

public void init(net.java.games.jogl.GLDrawable glDrawable)

Called by the drawable immediately after the OpenGL context is initialized for the first time. Initializes the perspective and view matrices, and activates lighting and rendering options. Part of the GLEventListener interface.

Specified by:

init in interface net.java.games.jogl.GLEventListener

reshape

public void reshape(net.java.games.jogl.GLDrawable glDrawable,
                    int i,
                    int i1,
                    int i2,
                    int i3)

Called by the drawable during the first repaint after the component has been resized. The client can update the viewport and view volume of the window appropriately. Part of the GLEventListener interface.

Specified by:

reshape in interface net.java.games.jogl.GLEventListener

display

public void display(net.java.games.jogl.GLDrawable glDrawable)

Called by the glDrawable to initiate OpenGL rendering by the client. After all GLEventListeners have been notified of a display event, the glDrawable will swap its buffers if necessary. Part of the GLEventListener interface.

Specified by:

display in interface net.java.games.jogl.GLEventListener

displayChanged

public void displayChanged(net.java.games.jogl.GLDrawable glDrawable,
                           boolean b,
                           boolean b1)

Currently unimplemented by JOGL, but required by GLEventListener. Does nothing.

Specified by:

displayChanged in interface net.java.games.jogl.GLEventListener

update

public void update()

Tells the GLCanvas that it should repaint itself ASAP.

getCamera

public Camera getCamera()

Gets the rendering Camera object associated with this DisplayHandler.

Returns:

the Camera object.

getLightManager

public LightManager getLightManager()

Get reference to the LightManager.

Returns:

reference of LightManager

yCord - the y-coordinate of the point at which to look.

zCord - the z-coordinate of the point at which to look.

setCameraLocation

public void setCameraLocation(float xCord,
                              float yCord,
                              float zCord)

Set the rendering camera's game world position.

Parameters:

xCord - the x-coordinate of the camera location.

yCord - the y-coordinate of the camera location.
