Help with Randomization of Non-Overlapping Images

[tamiskovich at gmail.com]

Hi all, 

I just got an email from a user today who had trouble posting to the board, 
but his solution appears to work so far. Here it is:

(I had trouble with google groups responding – I hope you’re the Tara who 
emailed the eprime group – if not please ignore – sorry…)

Hi Tara,

I'm not certain this will fix the problem, but I think the loop fails due 
to the precedence of OR vs AND in the conditional. The sets of X's and Y's 
need to be grouped together. Add the parenthesis shown beloww to hopefully 
fix the problem:

 

Loop While ((x2 = x1 Or x2 = x1 + 1 Or x2 = x1+2 Or x2 = x1 - 1 Or x2 = x1 
- 2) _

And (y2 = y1 Or y2 = y1 + 1 Or y2 = y1 + 2 Or y2 = y1 + 3 Or y2 = y1 - 1 Or 
y2 = y1 - 2 Or y2 = y1 - 3))_

Or ((x3 = x1 Or x3 = x1 + 1 Or x3 = x1+2 Or x3 = x1 - 1 Or x3 = x1 - 2) _

And (y3 = y1 Or y3 = y1 + 1 Or y3 = y1 + 2 Or y3 = y1 + 3 Or y3 = y1 - 1 Or 
y3 = y1 - 2 Or y3 = y1 - 3))_

Or ((x3 = x2 Or x3 = x2 + 1 Or x3 = x2+2 Or x3 = x2 - 1 Or x3 = x2 - 2) _

And (y3 = y2 Or y3 = y2 + 1 Or y3 = y2 + 2 Or y3 = y2 + 3 Or y3 = y2 - 1 Or 
y3 = y2 - 2 Or y3 = y2 - 3))_

or ((x4 = x1 Or x4 = x1 + 1 Or x4 = x1+2 Or x4 = x1 - 1 Or x4 = x1 - 2) _

And (y4 = y1 Or y4 = y1 + 1 Or y4 = y1 + 2 Or y4 = y1 + 3 Or y4 = y1 - 1 Or 
y4 = y1 - 2 Or y4 = y1 - 3))_

Or ((x4 = x2 Or x4 = x2 + 1 Or x4 = x2 + 2 Or x4 = x2 - 1 Or x4 = x2 - 2) _

And (y4 = y2 Or y4 = y2 + 1 Or y4 = y2 + 2 Or y4 = y2 + 3 Or y4 = y2 - 1 Or 
y4 = y2 - 2 Or y4 = y2 - 3))_

Or ((x4 = x3 Or x4 = x3 + 1 Or x4 = x3 + 2 Or x4 = x3 - 1 Or x4 = x3 - 2) _

And (y4 = y3 Or y4 = y3 + 1 Or y4 = y3 + 2 Or y4 = y3 + 3 Or y4 = y3 - 1 Or 
y4 = y3 - 2 Or y4 = y3 - 3))

 

Regards,

Bill
