Add Hidden Objects

What was It like to add Action-Script to your Objects? Well It was kinda hard Because I didn't knew how to add Action-Script and code my objects. The hardest part was where to hide them. It was hard because I want my players to have a hard time finding the objects. What king of game action would you like to add next? I actually don't know because I want my players to have a Hard time. I might do it more easy so my players can enjoy it.
