Hi I have created some code, which moves a rectangle around and when it hits
the edge it picks a random new direction. It does this by the count function
within my class. I am wanting to create a button to randomly change count but I
my class seems to be getting errors.
I also wanted to create a second class object tank2 but it doesn't seem to move
when I create it with tank2.Tank(x,y,vx,vy) and call tank1.move()
Can anyone help me many thanks.
