# Sierpinski Triangle Challenge!

#1

Hey everyone! I have a challenge for you that I myself would like to try. This is called the Sierpinski triangle:

It is a triangle within a triangle with in a triangle, etc.
I was thinking maybe this could be done on Hopscotch with clones and leave a trail blocks, do you have any thoughts? If you are up for the challenge, try it out and let me know how it goes!

Wow this looks cool!! I'll certainly give it a try!!

#3

This is what I've got so far:

It's a start...

#4

I've been thinking of this too, and I might give it a try :D

#5

Cool! I'd love to see what you can come up with! Do you have any ideas for methods that would work well to make it?

#6

I'll try!

#7

I can't wait to see it :3

#8

Hmmmmm it should be possible using clones. I might try it, but I have a few things I want to test before I try it.

Progress:

Nice job!! That's what I got to and then I couldn't figure out what to do after that.

#11

I'm starting to get confused too

#12

I would divide the other triangles into more triangles. Each of those can be made into four others.

#14

Wow!! This is amazing!!! I have been trying to figure this out, how did you it? What was the code? (I'm not going to copy I'm just curious)

#15

I think I've come up with a very elegant solution to this problem:

It uses some simple math to calculate the distance of how far it should move each time, and then it turns 120 degrees. The only recursion here is used for a "while loop".

The drawback to the method I came up with is time. It takes 2-3 minutes to fully draw out the triangle in the thumbnail, mainly because the method I use also has the object redrawing a lot of trails, and the fact that it takes time to calculate the distance it needs to travel.

#16

Very cool! I really like how you designed it with using little triangles to make the bigger ones. Also thanks for crediting me!

#17

Thanks! I think the little triangles is the easiest way to do it. And you're welcome for giving you credit!

#18

This is really really great!! Very clever!!

Hey Madi! Someone took me off your tag list, can you copy the updated one? I just put my name back on.
