I have recently been working on a small Processing-project, but I've got to a point where I'm pretty stuck...

The idea is that I have a group of points (extracted from an .svg file with the Geomerative library - the problem has nothing to do with the library, and therefore I posted it in this forum), from which I all want to draw brownian lines simultaneously.

I got to the point where I can draw a brownian line from any one point, but not from all at the same time. I think there's a small problem with the way I used the double for-loop, but I'm not sure...

I hope that someone could help me out. I will add my code below.

Thank you in advance.

It's been some time since I have last used processing, and thus stumbled upon a problem that might be simple to fix.

The idea is that I imported a random image when the mouse is clicked. With my current code, importing one random image is working fine, but i cannot manage to write anything with mouseClicked, that results in combining this with "void takerandomimage"...

I hope someone could help me out here. Thanks!
