Constructor Detail

SolarSystem

public SolarSystem()

Create a view of the Solar System. Once an instance of the SolarSystem class is created, a window of the appropriate size is displayed, and objects can be displayed in the solar system

Method Detail

paint

public void paint(java.awt.Graphics gr)

A method called by the operating system to draw onto the screen -

YOU DO NOT (AND SHOULD NOT) NEED TO CALL THIS METHOD.

Overrides:

paint in class java.awt.Window

drawSolarObject

public void drawSolarObject(double distance,
                            double angle,
                            double diameter,
                            java.lang.String col)

Draws a round shape in the window at the given co-ordinates that represents an object in the solar system. The SolarSystem class uses Polar Co-ordinates to represent the location of objects in the solar system.

Parameters:

distance - the distance from the sun to the object.

angle - the angle (in degrees) that represents how far the planet is around its orbit of the sun.

diameter - the size of the object.

col - the colour of this object, as a string. Case insentive.

One of: BLACK, BLUE, CYAN, DARK_GRAY, GRAY, GREEN, LIGHT_GRAY, MAGENTA, ORANGE, PINK, RED, WHITE, YELLOW

drawSolarObjectAbout

public void drawSolarObjectAbout(double distance,
                                 double angle,
                                 double diameter,
                                 java.lang.String col,
                                 double centreOfRotationDistance,
                                 double centreOfRotationAngle)

Draws a round shape in the window at the given co-ordinates. The SolarSystem class uses Polar Co-ordinates to represent the location of objects in the solar system. This method operates in the same fashion as drawSolarObject, but provides additional co-ordinates to allow the programmer to use an arbitrary point about which the object orbits (e.g. a planet rather than the sun).

Parameters:

distance - the distance from this object to the point about which it is orbiting.

angle - the angle (in degrees) that represents how far the object is around its orbit.

diameter - the size of the object.

col - the colour of this object, as a string. Case insentive.

One of: BLACK, BLUE, CYAN, DARK_GRAY, GRAY, GREEN, LIGHT_GRAY, MAGENTA, ORANGE, PINK, RED, WHITE, YELLOW

centreOfRotationDistance - the distance part of the polar co-ordinate about which this object orbits.

centreOfRotationAngle - the angular part of the polar co-ordinate about which this object orbits.

finishedDrawing

public void finishedDrawing()

Makes all objects drawn recently drawn to be made visible on the screen. Once called, all suns, planets and moons are displayed in the window.
