Hi Karin,

The "loop while" statement generally loops while a counter is less than a

number. You might set the counter to 0, have the counter increment by +1

each time it goes through the loop, and continue until a specified upper

limit is reached.


In the Flash 4 Magic Matching Game, the first loop makes a name: "smiley" &

a number = "smiley1" - "smiley12" for each of the pieces (and when it gets

to 12 - i.e., all the pieces - it quits). The second loop creates a location

and the 3rd loop (nested) assigns a smiley to that location. The first loop

is while the counter is less than or equal to 12 because that's all the

pieces. The 2nd loop makes spots row by row - so it creates row 1, column 1

to row 1 column 4 so it loops while the counter is less than or equal to 4

(then the nested loop places those tiles) then starts again for the next

row. The 3rd nested loop continues as long as it can find a smiley that

hasn't been placed, then goes back to making locations for the rest. They

both quit when all the spots on the board are taken up.


There are probably other situations, besides counting something, where you

might want to use a loop while, but I can't think of one off the top of my

head.


Hope this helps,
