This is the time to add textures to our plane from a movieclip.

Since I am making a card game, I want to store all cards in a single movieclip and assign each frame to a different plane.

At the moment I have only two frames, one with the front and one with the back of the card, because the creation of the “perfect card” is not over yet…

I am attaching the commented code, and please notice I NEVER add the card clip on the stage using addChild

All the uncommented code has been explained from part 1 to 4

And this is the result:

Click on the card to flip it.
