I’m working on the card matching game from flashgameu, in which a deck of cards with pairs of identical cards are layed out face down and the player selects pairs in an attempt to match them. (Same project as in a post from last night.)
The project is originally set up such that, when two selected cards match, they are removed from the stage. I changed this a bit – I leave the cards in place, and change their alpha to 0.25.
The problem is that simply changing the alpha value and keeping them on the stage maintains the player’s ability to click them. When clicked, they turn back over.
I want to take these matched cards “out of play” somehow while keeping them on the stage.
Here’s the code:

My first thought is that maybe? the card can be converted from a movieclip to a simple graphic? A bitmap? I have no experience with this so I don’t know if it’s possible. Perhaps the answer is much simpler. But I’m at a loss.
Thanks,
Tim
