Sure. Give me a bit.Process was trial and error, and I needto figure out what I did.- Create multi layer file in InDesign
- Turn of visibility to all layers except base layer
- EXPORT as interactive pdf - be sure to click on save layers box
- Open file in Acrobat
- EDIT pdf - find LINK tool
- open the Layers dialog box - pancake on left
- click on box next to the first layer you want to activate
- click "LINK / ADD/EDIT web or doc"
-crosshair tool should appear. Create shade box over item, (You will have a chance later to adjust box. Don't worry if not perfect.)
- When you release mouse, dialog box will appear
- "INVISIBLE RECTANGLE" / "NONE" / "NEXT"
- You now have opportunity to adjust your rectangle
- "SET LINK"
-Turn off layer
- You will see black outline of rectangle, but it will go away when fie is saved and opened in Reader.
- When you play the game, only one item will be revealed at a time.
- There may certainly be a better way to do this, but this worked for me. Let me know if any instructions need clarification. Have fun.
