- ->A few more ideas:

- ->- I think you missed my earlier suggestion about simplifying get_button().
I tried your suggestion for changing get_button() and
changed it to:
def get_button(click): # What peg was clicked?
for i, peg in peg_coords:
if click in peg:
return i + 1
return 0
but got this error.
Traceback (most recent call last):
File "test.py", line 120, in ?
sel1 = check_valid_start() # Verify valid start
File "test.py", line 40, in check_valid_start
but = get_button([x, y]) # Determine which peg position 1-15
File "test.py", line 60, in get_button
for i, peg in peg_coords:
ValueError: too many values to unpack
So I changed it back for now with plans to take a
closer look again later.
- ->- You have the same code in two places to initialize the board. Code
duplication is a strong "code smell" and it's generally a good idea to
eliminate it. In this case it would be easy to make a function to initialize
the board and call it in two places. The function can return the new board
which you can then assign to the state variable.
Agreed.
- ->- I think the program would benefit from having a Button class. Buttons
have several different states and behaviours which could all be bundled into a
class. The state of a button includes its location and whether it has a peg in
it. The behaviours of a Button are draw, add or remove a peg, and hit testing.
- ->
- ->If you make this change I would expect that peg_coords and state would both
be replaced by a list of Buttons. get_button() would look like this:
- ->
- ->def get_button(click):
- -> for button in buttons:
- -> if click in button:
- -> return button
- ->
- ->redraw_screen() would become
- ->
- ->def redraw_screen():
- -> screen.blit(board, (0, 0)) # Draw board
- -> for button in buttons:
- -> button.draw(screen)
- -> pygame.display.update()
- -> return
- ->
- ->Kent
Great! Thanks again for your suggestions and the link.
Time to do more reading. There is so much to learn,
but I'm gaining more confidence as I go.
Have a good day!
