Sprite

public Sprite()

Construct an instance of Sprite. By default, it is stationary.

Method Detail

setHotSpot

public void setHotSpot(Point inHotSpot)

Set the hot spot for the sprite. This sprite will be drawn such that the hot spot is placed at the position set by setPosition(danger.ui.Point) and subsequently changed depending on the sprite's velocity.

setHotSpot

public void setHotSpot(int inHotX,
                       int inHotY)

Set the hot spot for the sprite. This sprite will be drawn such that the hot spot is placed at the position set by setPosition(danger.ui.Point) and subsequently changed depending on the sprite's velocity.

setVelocity

public void setVelocity(Point inVelocity)

Set the sprite's velocity. This specifies the sprite's direction and how much it moves each time advance() is called.

setVelocity

public void setVelocity(int inVelocityH,
                        int inVelocityV)

Set the sprite's velocity. This specifies the sprite's direction and how much it moves each time advance() is called.

advance

public void advance()

Advance the sprite to the next position, dependent on the the velocity set in setVelocity(danger.ui.Point).

setPosition

public void setPosition(Point inPosition)

Set the position of the sprite.

setPosition

public void setPosition(int inX,
                        int inY)

Set the position of the sprite.

getPosition

public Point getPosition()

Get the current position of the sprite.

getPosition

public Point getPosition(Point inPoint)

Get the current position of the sprite.

Returns:

Always returns the point that was passed into it.

paint

public abstract void paint(Pen inPen)

Paint the sprite at the current location.
