Well, I can but it doesn't work properly. Here is what I mean:
-I can move up, down, and right, smoothly
-When I change the code to be able to move left, the following problems happen:
1. The screen skips bizarrely on some kind of delay.
2. The blue triangle marker on the right of the screen is supposed to become visible when the red square leaves the screen, and then it's supposed to follow the red square's Y coordinate. That all works until I change the code in order to go left, because when I make it go left the code for the blue marker no longer works.
I got some help for this from another good member and he did great job helping me to get it to the point it is now, but this one last piece is maddening :-(
