Hi there,
I have been working on a Pure Pursuit code. I understand the concepts of PP, and how to use it. However, I am using the math from someone else’s code. Previously, I got it to work fine for me, but when I tried to do it again, it showed an error with int R4. The error pretty much says that R4 is undefined and it cannot take the square root. I am using a C++ compiler for all my debugging because it does not work for me to have V5 or V5pro downloaded. I think the error may be in the A8 B8 C4 and D4 lines. Can anyone help? I understand that this is not a very usual format for PP.
