STEP 13: Before we make the top block, we need to make sure there's a gap between the top and bottom blocks.
- Go to the LOGIC tab and the toolkit. Drag Addition onto the next line in make_blocks().
- Change my_var to y2. Replace the 2 with y1 and replace 3 with 150. (150 is half the bottom block's height)
- y1 plus 150 gets us to the top of the bottom block. Then, add + block_gap + 150 to the equation.
By adding block_gap and half of the top block's height, we calculate y2 which is the y-position of the top block.

# Program variables (DON'T DELETE!!!)
block_speed = -6 # controls how fast the pipes move across the stage
block_gap = 200 # controls the space between the top and bottom of each pipe
block_interval = 1 # controls how often a new pipe appears
gravity = 8 # controls how fast the sprite falls
flappiness = 5 # controls how much the sprite moves up
# Store and display score
score = 0
score_text = codesters.Text("Score: " + str(score), 100, 200, "yellow")
