Scratch

Thanks Legolas_Greenleaf! 

Hi Slinger,
I found your post while looking for how to implement lists. So I have an idea for you we can cooperate around if you like. I want to simulate a location based game in Scratch. So I have to find a way to keep track of the locations (x,y) of all my sprites. As a first functionality I would like to implement a function nearest that find the two sprites that are nearest. I would like to use the stage as a kind of server that implement these functionalities. I want to do something like
vectorX contains all x's
vectorY contains all y's
position 1 is initialized to MAX
position 2 is initialized to MAX
distance is iniziatized to MAX
for i = 1 to lengthOfList
for j= 2 to lengthOfList
{
a= vectorX(i)-vectorX(j)
b=vectorY(i)-vectorY(j)
if sqrt(a*a+b*b)<distance
{
position1 = i
position 2 = j
distance= sqrt(a*a+b*b)
}
}
}

But how to implement in Scratch something like
vectorX(i)?

Make a hunting game where you shoot ducks in a grassy field, with the help of your dog.

No, wait.

Maybe some mathematical generator (A complex one)

ideas are hard to come by, bit sometimes you get a idea worth 100 million while sitting in washroom. so spend more time in washrooms.  .
