Effect()

activate(boolean)

Sets the activation state of the effect to true (activated) or false (not activated)

fxSetActive(boolean)

not applet visible

fxSetLimits(int, int)

not applet visible

getOutputView()

Gets the output View for this effect.

isActive()

returns the current activation state of this effect.

objApplyEffect(int)

not applet visible

objRemoveEffect(int)

not applet visible

rippleChange()

Not applet visible.

setInputView(Rectangle)

Not applet visible.

setOutputView()

Not applet visible.

setParams()

Not applet visible.

toggle()

Toggles the activation state of this effect (if it is active, it is deactivated and vice versa)

toString()

Returns the String representation of this Effect's internal state.

  public Effect()

  protected int fxSetActive(boolean cond)

not applet visible

  protected int objApplyEffect(int hObj)

not applet visible

  protected int objRemoveEffect(int hObj)

not applet visible

  protected int fxSetLimits(int width,
                            int height)

not applet visible

  public boolean toggle()

Toggles the activation state of this effect (if it is active, it is deactivated and vice versa)

Returns:

false if the toggle failed, true otherwise

See Also:

isActive, activate

  public boolean activate(boolean cond)

Sets the activation state of the effect to true (activated) or false (not activated)

Parameters:

cond - if true, it activates the effect; deactivates otherwise.

Returns:

false if the activate failed, true otherwise

See Also:

isActive

  public boolean isActive()

returns the current activation state of this effect.

Returns:

true if the effect is active; false otherwise.

See Also:

activate

  protected abstract boolean setOutputView()

Not applet visible. Sets the ouput view of an effect based on its current input view. This is an abstract method that each effect implements based on the way that it effects the data

Returns:

false if Parameters are out of range for this effect. true otherwise

  public Rectangle getOutputView()

Gets the output View for this effect. This is a rectangle that defines the output of this effect. It is in the coordinate system of the sprite.

Returns:

OutputView of effect.

  protected boolean rippleChange()

Not applet visible. Internal method used by all effects to ripple their changes in input and output views downstream to other effects and the sprite.

Returns:

false if rippling this change downstream caused a downstream effect to have out of range parameters. true otherwise

  protected boolean setParams()

Not applet visible. Used by concrete subclasses of this class to actually set parameters for the effect if they have changed and are within range

Returns:

false if setParams failed, true otherwise.

  protected boolean setInputView(Rectangle rect)

Not applet visible. Specifies the input rectangle for this effect. This is a rectangle that defines the input region for this effect. The input rectangle is on the coordinate system of the sprite. This method then adjusts the effect's output view accordingly and ripples changes to downstream effects and the sprite. This method is used by an effect A that is applied immediately before effect B to inform effect B about the input Rectangle that is going to be presented to it

Returns:

false if the passed in rectangle has 0 or negative height or width or if it parameters for this effect or a downstream effect to be out of range. true otherwise

  public String toString()

Returns the String representation of this Effect's internal state.

Overrides:

toString in class Object
