- Anfy Flozoids - Copyright (C) by Fabio Ciucci 1997/98
-
-
- This applet can animate in realtime an artificial life algorithm, where
- some "flozoids" are flying (or swimming) around.
- I have to thank Jeff Cragg and Alex Vulliamy for this idea.
- Remember that are needed both flozoids.class and Lware.class.
- You must upload these 2 .class files and insert the <applet> tag on your
- html document to add this applet to your page.
- This applet is fully parametrized, so you can change many things to
- adapt the effect to your pages and purposes.
- Here an example of what you have to write in the html (the things anfter
- the ; are comments with min-max values acceptet):

-
-
- Here detailed instructions about how to change parameters:
-
- The credits parameter can't be changed otherwise the applet will not work.
-
- To activate the reg parameters read the shareware registration notes.
- In the "regcode" parameter you have to place the registration code you
- purchase from the author. If it is correct and the applet is run from the
- registered domain name, you can use "reglink" parameter, where you can specify
- an URL where bring user when the applet is clicked.
- If you set to "YES" regnewframe, you can specify a frame where load the
- reglink:
-
- "_blank" : To load the link in a new blank unnamed browser window.
- "_self" : To load the link into the same window the applet occupies.
- "_parent" : To load the link into the immediate FRAMESET parent.
- "_top" : To load the link into the top body of the window.
-
- Otherwise the frame name, for example "myframe1".
-
- The size of the applet is determined by width and height tags.
-
- The number of flozoids is determined by "numfloz" parameter: more flozoids
- mean slower execution.
-
- The behaviour of flozoids can be altered with these parameters:
-
- "flozdistance" : it determine how much a flozoid can go far from others
- "tocenter" : it determine the tendence to go to center of screen
- "acceleration" : it determine the acceleration power of flozoids
- "speed" : it determine the max speed a flozoid can reach
- "sidebouncing" : it determine the intensity of bouncing when edges of the
- applets are reached.
- "fheads" : it determine if flozoids have heads or not.
- "overtext" : it determine if flozoids can overwrite textscroll.
-
- You can change the colours for best results over your web page, the RGB
- values are same as HTML tags, but in decimal values.
- Use backR,backG,backB to change background color.
-
- If you want to display an image in the background, place it's name in the
- place of "NO" at backimage parameter (for example "back.jpg").
- The only requirement is that the background image must be same size as the
- applet to completely cover it.
-
- About flozoids color, you can choose the first and last color of a gradient
- that will be spread over all the flozoids: flozR1,flozG1,flozB1 for first
- color, flozR2,flozG2,flozB2 for last color of gradient.
- Examples: to make ALL the flozoids white, place 255 as value for all the
- flozR1,flozG1,flozB1 and flozR2,flozG2,flozB2.
- To make flozoids coloured from black to white (all the intermediate grays),
- place a value of 255 for flozR1,flozG1,flozB1 and a value of 0 for second
- color: flozR2,flozG2,flozB2.
- Offcourse you can make rainbows (from red to blue, etc.).
-

-
-
- Optional Scrolltext parameters:
-
-
- You can optionally activate a scrolltext that will scroll over the applet.
- If you don't need the scrolltext, deactivate it placing "NO" at the
- "textscroll" parameter.
- Otherwise you must supply the name of an ASCII text file, where you must
- write the text that you want to be scrolled.
- Is supported one only line of text, that can be long as you want.
- Remember to upload the text file too, if you activate the scrolltext!
-
- If activated, here are the parameters:
-
- With "textoffset" you choose the Y offset from the top: placing it to 0 the
- scroll will be placed on the top, for example, and placing a value near the
- height of the applet it will scroll at the bottom.
-
- With "textspeed" parameter you decide the scrolling speed.
-
- With "textfont" you choose the font of text. Don't choose a strange or not
- standard font, not present in all systems.
- The most common fonts are "Arial", "TimesRoman" and "Courier".
- If the required font is not present, the most "near" will be used.
-
- Setting "textbold" to "YES" you will enlarge a bit the font, otherwise set
- it to "NO" for normal contours.
-
- With "textsize" you can change the size of text font.
- The most common sizes are: 8,9,10,11,12,14,16,18,20,22,24,26,28,36,48,72.
- Intermediate values will be scaled to nearest available size.
-
- Setting "textshadow" to "YES", a shadow will be added to textscroll.
- Otherwise, setting it to "NO", any shadow will be "projected".
-
- You can choose the color of text with:
-
- TextColR = Red component of color (0-255)
- TextColG = Green component of color (0-255)
- TextColB = Blue component of color (0-255)
-
- For example, 0,0,0 is black, 255,255,255 is white, 255,0,0 is red,
- 255,255,0 is yellow, 128,128,128 is grey.
- You can compose any color you want, do it trying manually or use any paint
- program's color selector to find Red Green Blue components of your desired
- colors.
-
- With TextSColR,TextSColG,TextSColB you can select the color for text shadow.
-
- If you like, you can activate the text jumping function.
- If "TextJumpAmp" is set to "0", any jumping will be shown.
- But increasing the value will result in text jumping: more aplitute, more
- high jumps.
-
- With "TextJumpSpd" parameter you can select the jumping speed.
-
- If you like, you can also activate the sine scroll function.
- If "TextSineAmp" is set to 0, no sine distortion will be generated.
- But increasing the value will result in the that the text is waving. The
- higher amplitude, the more waving.
-
- With the "TextSineSpd" parameter you can select the speed of the wave.
-
- With the "TextSineAngle" parameter you control how many degrees in a sinewave
- shape the text will be deformed for each pixel. A higher value gives more
- distortion.
-

-
- Compatibility parameters:
-
-
- The "memdelay" parameter is useful only to run the applets without problems
- on some bugged versions of Netscape 3, that don't deallocate correctly
- the memory allocated, resulting in filling all the memory after a minute
- the applet is running. This can cause also a system crash in some cases.
- Last versions of browsers have fixed this problem, but if you want to run
- the applets on old bugged browsers too, set "memdelay" to low values, like
- "10" or "16", for example.
- But this will slow down a lot the applet speed, so you have to choose
- between speed (memdelay set to 1000 or higher) or slow compatibility with
- old browsers (memdelay set to 20 or lower).
-
- The "priority" parameter is useful mainly when you are running more than
- one applet in same page, and one slows down or hangs.
- If this applet run too slow or hangs because other one steal all the CPU
- power, try increasing the priority.
- Otherwise, if this applet runs well and others slows down, decrease the
- priority. Consider the min priority is 1, normal priority is 5, and the
- max priority is 10. Usually a priority of 3 is ok for single applets.
-
- The "MinSYNC" parameter must be set to a value between 8 and 16 to slow
- down animation in the case it runs too faster on faster computers or because
- the applet size is very small. The optimal value seems to be 10, but you can
- disable this feature placing a value of 0 if you see flickerings or excessive
- slow down.
- If the applets steal 100% of CPU power or slows down the browser and Operating
- System, try increasing MinSYNC until all runs ok.
- Usually values between 40 and 400 fixes all problems, even if applet slows
- down for compatibility.

- the author of the applet, I placed a secret linkware window that will appear
- if the applet is clicked with mouse, only when the applet is online on a site:
- it is external to the web browser, so it will not hit the design of your
- beautyful html page.
- This small window will simply show my name and ask for a link to my java
- applets page.. the user can connect to it or cancel, or hide the window and
- connect after visiting all your pages.
- I hope this credit part is not a problem for you...
- In any case, if link is accepted a new browser window will appear and your
- page will remain on the original window, so you will not lost the visitor.
- Consider you will use an effect programmed by me, without pay, for FREE!

- NOTE: You can include the applets archive on CD-ROMS or shareware collections
- and shareware sites without ask me, but only if you leave the archive(s)
