Constructor Detail

CAnimatedSprite

public CAnimatedSprite(IGameDisplay gameRect,
                       CBoundingBox box,
                       CVector2D velocity,
                       java.awt.Image imgSprites,
                       float[] aFrameTimes)

Parameters:

gameRect - : the rectangle the sprite will evolve in

box - : the sprite's bounding box (can be different than image size)

velocity - : sprite's initial velocity

imgSprites - : the sprite's image array

aFrameTimes - : the frame time indexes array

CAnimatedSprite

public CAnimatedSprite(IGameDisplay gameRect,
                       CBoundingBox box,
                       CVector2D velocity,
                       java.awt.Image imgSprites,
                       float fFrameTime)

Fixed frame time version of the above.

Parameters:

fFrameTime - : the constant frame time.

Method Detail

splitSprites

private final void splitSprites(java.awt.Image img)

Takes an Image and splits it in a sprite array. Uses a CImageProcessor to split the Image.

Parameters:

img - the image containing the sprite animation

CImageProcessor

generateTimeIntervals

private final float[] generateTimeIntervals(float fFrameTime)

Generates an array of equal time intervals.

Parameters:

fFrameTime - the fixed time interval

Returns:

an array of fixed time intervals

initTimeIntervals

private final void initTimeIntervals(float[] aTimeIntervals)

animate

public final void animate(float dt)

Animates the sprite. Contains the major part of the magic.

Specified by:

animate in interface IGraphicObject

Overrides:

animate in class CDynamicShape

Parameters:

dt - : the amount of time to advance of.

draw

public void draw(java.awt.Graphics g)

Simply draws the current image.

Specified by:

draw in interface IGraphicObject

bounceOnGameRect

protected void bounceOnGameRect()

Same as inherited function. Except that it reverses the animation for demonstration purpose.

Overrides:

bounceOnGameRect in class CDynamicShape

isCritical

public boolean isCritical()

Specified by:

isCritical in interface ICriticalObject
