fixed point question

[Lolboer9999999]

Hello

I was using this library to make a cord that hangs from the top of the page you can pull on and it works great but the one issue i have is that the point that is fixed can still be moved by the mouse, is there a way to prevent that

edit: setting the radius to 0.001 seems to work to hide the first point but if someone has a better suggestion let me know
