Drag-And-Drop Puzzle: Disabling Correct Pieces
I'm attaching the relevant slide - it is the Sink layer where I am having the issue.
Users will drag and drop puzzle pieces to reveal a picture (it's a lemon) and once the variable reaches 9 (number of pieces), a rectangle with an explanation changes its state to normal.
I'm having a couple issues.
1) I want puzzle pieces to become disabled once they've been dropped into the correct spot. I tried to change state to disabled via a trigger, but that has done nothing. I changed puzzle piece #5 to a shape instead of a picture to see if that would do anything, and it didn't.
1a) Fixing issue #1 would likely solve this problem, but currently, my variable can still increase if I touch the piece and drop it in the correct spot more than once. I really need my puzzle pieces to stay still once they're correct!
2) My puzzle pieces aren't quite aligned with the chart. There's tiny gaps and it's driving me crazy. Any ideas? The puzzle board is a table and all the pieces are identical in size. But I can't quite get the pieces to fit perfectly.
Any ideas? Do I need another variable? Thanks in advance for your help!
