GENERAL NOTES
-------------------------------------------------------------------------

// CodeBrainQuasar's code is written protectively -- to make it easy
// to set up and get running.  Six demos and all the associated
// graphics and sound files are included, to get you rolling quickly.
//
// Other than the "Notice" parameter and one image file (any one),
// you can leave out any parameter and the applet will run.
// That is, "If in doubt, leave it out!"
//
// You can make the applet as simple as you wish, without the
// clutter and confusion of a multitude of parameters -- and then
// gradually build upward into more complex renditions.
//
// Parameter names are as descriptive as we can make them without
// having them a mile long, and they ARE case sensitive, so take care.
// On parameters with multiple values, make sure you put a value
// in each slot.
//
// Note that a keyfile is required (see below) to run the applet on
// your website.
//
// Keep image files to the smallest dimensions and file sizes
// possible.  There's a great deal of redrawing going on -- so
// large images backload the applet and slow it down.
// (Note that the BackImage is NOT a traditional background image;
// it is just an image that sits in back of all others -- so keep
// that small, as well.)
//
// To get started, place the CodeBrainQuasar.class file and ALL
// files used by the applet in the SAME directory
//
// Check out the six demos included, and gradually change parameters
// to get a feel for how the applet works.
//
// Good luck, and we hope you have a blast with CodeBrainQuasar.class.
// It's a remarkably flexible and powerful applet, well worth the
// small investment of time it takes to learn to use it well.
//
// Best regards,
//
// CodeBrain
//
// IMPORTANT:  CodeBrainQuasar.class will function properly off your
// disk drive, as is.  To use it on your website, you MUST MUST MUST
// get a KEYFILE from www.CodeBrain.com -- or the applet won't run.
// The KEYFILE, CodeBrainQuasar.key, must be in the SAME DIRECTORY
// as the CodeBrainQuasar.class file.

=========================================================================



<param name="Notice"                 value="Applet by www.CodeBrain.com">
-------------------------------------------------------------------------
// Must be present, EXACTLY, or the applet will not run.  (See note
// above, you also need a keyfile to use the applet on your site.)



<param name="TimeConstant"                                  value = "50">
-------------------------------------------------------------------------
// Sets the overall speed of the applet.
// Smaller values are faster, larger are slower.
// Practical range is usually around 10-200.
// Getting started... try 50.



<param name="BackgroundColor"                        value="rrr,ggg,bbb">
-------------------------------------------------------------------------
// This sets the applet background color.
// Usual RGB format, values 0-255.
// Example: value = "255,0,0" would make the applet background red.



<param name="BackImage"                        value="imagefilename.ext">
-------------------------------------------------------------------------
// This image will sit at z-index zero, behind all others.
// The file can be a .gif, an animated .gif, or a .jpeg.
// Keep image files as small in dimension and file size as possible.



<param name="BackXY"                                         value="X,Y">
-------------------------------------------------------------------------
// Where the BackImage will be positioned, upper left corner of image.
// X is pixels across, Y is pixels down.
// Positioning at values less than zero or larger than the dimensions
//    of the applet will place it completely or partly off-screen.
// Example, if your applet is 200 wide and 300 high, value="100,150"
//    would position the BackImage upper left corner dead center



<param name="FrontImage"                       value="imagefilename.ext">
-------------------------------------------------------------------------
// This image will sit in front, on top of all others.
// The file can be a .gif, an animated .gif, or a .jpeg.
// Keep image files as small in dimension and file size as possible.


<param name="FrontXY"                                        value="X,Y">
-------------------------------------------------------------------------
// Where the FrontImage will be positioned, upper left corner of image.
// X is pixels across, Y is pixels down.
//
// Use integers, i.e., value="75,95"
//
// Positioning at values less than zero or larger than the dimensions
//    of the applet will place it completely or partly off-screen.



<param name="FloatImage"                       value="imagefilename.ext">
-------------------------------------------------------------------------
// The FloatImage is one of two active (moving) images in the applet.
//    It's z-index or layer is adjustable, to fall anywhere above
//    the BackImage and below the FrontImage -- see FloatZ.
//
// There are a total of 9 modes of motion -- see FloatMode.
//
// The file can be a .gif, an animated .gif, or a .jpeg.
// Keep image files as small in dimension and file size as possible.



<param name="FloatXXYY"                value="Xleft,Xright,Ytop,Ybottom">
-------------------------------------------------------------------------
// This is a bounding box, dimensions in pixels.
// Xleft is as far as the image will travel left.
// Xright as far as it will travel right.
// Ytop as far up as it will go.
// Ybottom as far down as it will go.
//
// Use integers, i.e. value= "20,200,30,150)"
//
// You can use negative values and values greater than the size
//    of the applet... useful in moving the image off-screen



<param name="FloatZ"                                           value="0">
-------------------------------------------------------------------------
// FloatZ is at what depth (what layer) the FloatImage will be postioned
//    RELATIVE to the FlyImage (see below).
// For example, if you set up the FlyImage FlyHowMany (see below) for
//    seven images, setting FloatZ to "3" would cause the FloatImage
//    to hover between the third and fourth FloatImage



<param name="FloatMode"                                        value="0">
-------------------------------------------------------------------------
// The FloatImage has 9 modes of motion.
// These modes are:
//    0 = static
//    1 = left to right
//    2 = right to left
//    3 = horizontal bounce
//    4 = top to bottom
//    5 = bottom to top
//    6 = vertical bounce
//    7 = circles clockwise
//    8 = circles counterclockwise
//    9 = random (moves pseudo-randomly through modes 1-4)

// Only modes *7,*8, and *9 have speed control; see FloatSpeed789 (below)



<param name="FloatSpeed789"                                   value="25">
-------------------------------------------------------------------------
// Sets how fast the FloatImage moves -- modes 7,8,9 only
// Larger values are faster; try 25 to get started.




<param name="FlyImage"                         value="imagefilename.ext">
-------------------------------------------------------------------------
// The FlyImage is the second of the two active (moving) images.
//    It creates multiple copies of itself (see FlyHowMany),
//    and has three main parameter sets to control how it moves.
//    All though all of the motion is based on Sine/Cosine (circular)
//    relationships, changing these parameters results in
//    a remarkable range of variation.
//
// The file can be a .gif, an animated .gif, or a .jpeg.
// Keep image files as small in dimension and file size as possible.



<param name="FlyHowMany"                                       value="3">
-------------------------------------------------------------------------
// How many copies the Fly Image will present.
// Practically, you probably want to keep this between 1-20 or so.
// Make sure you set FlySeparateMaxMinROC (below) so you can see.



<param name="FlyDirection"                                     value="1">
-------------------------------------------------------------------------
// Which direction the Fly image orbit will rotate.
//  0= ccw, 1 = cw



<param name="FlyCenterXY"                                    value="X,Y">
-------------------------------------------------------------------------
// This is the starting CENTER position of the image.
// The applet automatically takes into account the width and height of
//    the image!
// Thus, if you have an applet that is, say, 300 wide by 300 high,
//    value="150,150" will exactly center the image, no matter what
//    the image dimensions are.  (Say thank you.)



<param name="FlyOscillateXXYY"               value="Xmax,Xmin,Ymax,Ymin">
-------------------------------------------------------------------------
// This is the most important parameter for motion.  You WILL need to
//    experiment with it, and it DOES take some fiddling, though it's
//    very well behaved when you get the hang of it.
//
// Take NOTE... this is NOT a bounding box -- it is an oscillator, and
//   the values are for the limits.  The values are relative to the
//   FlyCenterXY point, and they are the radii -- not the diameters --
//   of the circles/elipses that the FlyImage moves through.
//
//   Xmax - maximum to which the radius will expand, left-to-right
//   Xmin - minimum to which the radius will contract, left-to-right
//   Ymax - maximum to which the radius will expand, top-to-bottom
//   Ymin - minimum to which the radius will contract, top-to-bottom
//
// Getting started... look at the demos included and work with them,
//    changing values a little at a time.
//
// Use integers, negative numbers are allowed -- with sometimes very
//   interesting results!



<param name="FlySpeedMaxMinROC"                       value="Max,Min,ROC">
-------------------------------------------------------------------------
// This adjusts how fast the FlyImage will move.
// Max is the maximum speed, Min is the minium speed, and ROC stands
//    for RateOfChange between the Max and Min speeds.  That is,
//    if you used value="20,2,11", the FlyImage would speed p to 20,
//    then slow down to 2 -- and the CHANGE in the speed would occur
//    at a RATE of 11.  This changing speed adds life to the applet,
//    and reduces the sensation of repetition.
// Again, work with the demos, changing this a little at a time.  The
//    effects can be starting.
// For a static (unchanging) speed, set Max and Min the same, and the
//    rate to any value; for example, value = "9,9,0"
// Decimal (i.e., 1.15) and negative values are allowed.



<param name="FlySeparateMaxMinROC"                   value="Max,Min,ROC">
-------------------------------------------------------------------------
// This adjusts how far apart each copy of the FlyImage will be.
//   (For those interested, the value is in radians.)
// Similar to setting up the parameter above, Max is the maximum
//   distance between images, Min is the minimum distance, and ROC is
//   the rate at which the distance between the images changes.  Work
//   with the demos!  Pushing the ROC up past 11 or so can have
//   fascinating results.
// For a static (unchanging) distance, set Max and Min the same, and the
//    rate to any value; for example, value = "9,9,0"
// Decimal (i.e., 1.15) and negative values are allowed.



<param name="SoundFile"                         value="soundfilename.au">
-------------------------------------------------------------------------
// This is the name of a sound file you may optionally associate
//    with the applet.  There are three modes, see below.
// The sound file MUST be a standard, JAVA .au file.
// Keep the sound file as small as possible, especially for sync mode.



<param name="SoundMode"                                        value="1">
-------------------------------------------------------------------------
// The associated SoundFile (above) can be set to trigger in three
//   different modes, as follows...
//   1 = plays the sound only when the applet opens
//   2 = plays the sound continuously (loop)
//   3 = sync mode -- plays the file syncrhonized with FloatImage motion




<param name="StatusBarTextS"           value="Static status bar message">
-------------------------------------------------------------------------
// Optional, a text message the applet displays in the browser status
//    bar whenever the mouse is NOT over the applet.



<param name="StatusBarTextM"        value="MouseOver status bar message">
-------------------------------------------------------------------------
// Optional, a text message the applet displays in the browser status
//    bar whenever the mouse IS over the applet.



<param name="Link"                      value="http://www.codebrain.com">
-------------------------------------------------------------------------
// Optional, a link to which the applet will send the browser when you
//    click on the applet.  Make sure you use the full path, as shown!



<param name="Target"                                        value="_new">
-------------------------------------------------------------------------
// Optional, used in conjuntion with the Link parameter above.
// This is in standard syntax -- _new, _top, etc.; or the name of
//    the target frame if you are using a framed layout.
