Open the actionscript panel on the actions layer. You will see that a character called blob is positioned on the stage at x = 500 and y = 325.
You will also see that the xDirection of the blob is 0 and the yDirection is -1.
In the game loop, the xDirection value and the yDirection value are used to make the blob move.
DON'T RUN THE PROGRAM YET!! Which direction do you think the blob will move in.
Run the program. Did you guess right?!
