Method Detail

act

public void act()

actively interact with the world. Before act() is called the component is moved forward according to it's direction.

getDirection

public java.awt.Point getDirection()

returns a Point representing the direction the component is travelling. The x and y coordinates range between -100 and 100 and are interpreted as hundreths of a pixel to move per iteration.

setDirection

public void setDirection(java.awt.Point d)

sets the direction of the component. The given point's coordinates should range from -100 to 100, and will be interpreted as hundreths of a pixel per act().

getTimeBetweenActs

public int getTimeBetweenActs()

returns the time in milliseconds between act()s. Represents the velocity / frequency of the component.

Returns:

int milliseconds between calls to the act method.
