Star Nusery

I was very impressed by this example of processing in the exhibtion part of the website, I have been playing with it trying to get the same sort of visual effect in reaction to A int reuturned from a database.
for example if the number returned is with the rage 1-10 and I get an 8 I want there to be a larger "burst" of stars than if I was returned a four . I have been trying to get the code to do this so far by attempting to save a more basic sense of the ersult ( a bright circle ) then passing it as video put it dosnt work
As you might be able to tell from other posts I kinda suck at maths so I know what I want to do but I dont really no how to do it ( isnt that always the case )
cheers

Hmm hi, I'm ryan. i wrote the star nursery sketch. It seems like it would be pretty hard to get the star code as it is to work with that kind of input.. Right now it reacts to light and dark in an imput image. If an area changes from light to dark then the stars grow, and touch each other, causing them to light up and connect to other stars. So maybe that's the burst you're talking about.
I think maybe the best way to do what you want is instead of generating images to input into the star code that's already there, you could just change the code so that stars die after a certain age and then are created based on your number..

Well I can't go too in depth cuz of this other project im working on, but if you want to make more stars with the code that's there, you just have say
Code:| stars[nStars] = new Star(nStars, random(width), random(height), random(-5, 5), random(-5, 5)); |
|
and then increment the number of stars like this
Code:
If you're gonna be making them and deleting them then you should probably revamp the code so that when you delete one it just shifts all of the stars after it up one in the array with System.arraycopy(stars,IndexOfStarYouWantToErase+1,stars,IndexOfStarYouW antToErase,nStars-(IndexOfStarYouWantToErase+1)); and then nStars--;
I think that should work.. There might be errors.. 
Um I'm in LA by the way, in VeniceBeach right now..

replying to my self with yet another question..
my current problem is that the star picture isnt displayed the entire code that I am using is at this address http://sdcc13.ucsd.edu/~jstehhou/oneStar ( its to long to post), ( there is also a sound out put associated with the 'match' value, hence the sonia code it is also going to be taking streaming gps data via the nmea prtocol) If you can hold odwn the tilde key (~) you can see the bounding circles but the star gif isnt being displayed. it is being loaded though, is how I have adjusted the diameter the right way to go about things?
cheers
