# Help with Magic8Ball (scenes) browsing

• Magic8Ball is a game that gives you advice.
The first scene (MyScene), says the name of the game.
The second scene (Help), gives instructions.
However, I need help with making the code pick another random advice (answer).

Here's the code:

<pre><code>

choice=randint(1,7)
if choice==1:
elif choice==2:
elif choice==3:
elif choice==4:
elif choice==5:
elif choice==6:
answer="Makes no\ndifference to\nme, do or don't\n- whatever."
else:
answer="Yes, I think on\nbalance, that is\nthe right choice."

class Particle(object):

self.w = wh.w
self.h = wh.h
self.x = randint(0, self.w)
self.y = randint(0, self.h)

self.vy = randint(-10, 20)
self.colour = Color(random(), random(), random())

``````def update(self):

if self.x < 0:
self.x = 0

self.y = 0

You seem like you have past experience in programming, just not in Python. I could never have pulled off that particle effect, but your code looks to me like a beginner wrote it. There's a lot of redundancy.

• Yes, I had past experience with python and I'm actually really good at it but I'm still getting used to Pythonista's scenes, layers and everything.

Great! Good luck :)

• @Webmaster4o @omz @blmacbeth
I'm about to make another post on a small code I need help with. It would be nice if you guys could look at it.

@Pythonistapro777 It would be great if you could post this code into a GitHub repo.

To do so, go to `https://github.com/Pythonistapro777/Magic8Ball` and look for a line that has:

• a `green icon of arrows` on the left followed by
• a `Branch: master` button followed by
• `Magic8Ball / +`

If you click on that `+` you can add a new file to the repo (that part of the UI is not super intuitive!!)

Call the new file `Magic8Ball.py` and paste in your code. We can then send you code suggestions ("pull requests") which you are free to accept, reject, or ignore until you have the code for a perfect eight ball.

• Sure, and thanks for the instructions, because I couldn't seem to be able to upload anything I made. :)

• I'm gonna Finnish my current projects and upload them
with the Magic8Ball. Should be up by the end of this week.

I have a refactored 8ball that I will submit once the repo is ready.

• Cool, can't wait to see it!

Add an empty Magic8Ball.py to the repo and I will submit a pull request.

Internal error.

Oops! Looks like something went wrong!
