I have an issue with the Scatter extension. I am basically trying to make a spiky ball, so I make a circle and a triangle. I want to use scatter to make the spiky ball, but I end up with this.

Traceback (most recent call last):
  File "pathscatter.py", line 165, in <module>
    PathScatter().run()

    s += dx
UnboundLocalError: local variable 'dx' referenced before assignment

Here are the hardware specs.

I am running Windows 10 x64 Pro 21H1 ver. 19043.1110. As for extra devices, I have a Gaomon S620 Tablet. 

I use official installation packages from inkscape.org - my version of Inkscape is Inkscape 1.1 (c68e22c387, 2021-05-23).

Is the triangle above the circle as described in its help tab?

Yes, it is.

Can´t help as it works here:

Just in case; can you try my example file which works here?

Ok something is definitely off...

Just wanted to say I'm getting that same python unbound local variable 'dx' issue when following these steps with the latest Inkscape (v1.1) on Win 10 when I have the Follow Path Orientation box checked.

Disabling that feature by unchecking the box allows me to use the tool as normal.

As an aside I wish this tool allowed a random position offset per object scattered, you know to actually scatter the pattern/path/object instead of basically doing almost the same thing as Pattern Along Path with Repeat.

@Igolugo Please report bugs with Inkscape at https://inkscape.org/report .

I tried the latest development build and it seems to work fine there. I guess the bug has been taken care of after the release of Inkscape 1.1
