number of overlapping objects

[Gabriel]

I am trying to make a sudoku solver and I am stuck because I don't know how to compare the number of objects overlapping another. Eg Number of "active" overlapping "active 2" > 2.

loop through all objects using a fast loop and check each individual object... if it overlaps add 1 to a counter/alterable value... if value &gt; 2... you're good to go <img src="/center/images/graemlins/wink.gif" alt="" />

+ Start of frame
-   Spread value A = 0 in "active"

+ whatever trigger here
-   Start fast loop "check objects" (count "active") times

+ On loop "check objects"
+ Value A of "active" = loopindex("check objects")
+ "active" is overlapping "active2"
-   Add 1 to Counter

something like that

Thanks, that worked. Now I need to do the same, but only start the loop if two of the actives are overlapping and facing the same direction.
