Random Walk Generator C# Scripting Tool

Hi Everyone,

This is my first post and I'm extremely new to C# so please be gentle!!

I'm trying to create a Random Walk tool that draws RandomWalks across a circle. Once the Walks has past the circumference of the circle, a new Walk is started. The tool then ends when the total length of all walks has exceeded the StopWhenLongerThan value.

I have attempted to transfer the tool from a javascript code written by my supervisor. I'm sure the tool is crawling with errors..

So I was wondering if somebody could have a look and help me find out where I've gone wrong or perhaps suggest a simpler way of doing things!

Thanks in advance for your help!

I've attached the grasshopper file too.
