Post Errors when compiling polargraphcontroller

Windows, running processing 3.1.2, getting some errors when compiling the latest code downloaded from https://github.com/euphy/polargraphcontroller/releases/tag/2016-03-29-10-23

For instance:
size(windowWidth, windowHeight);
(cannot be defined as variables, must be sett in numbers).

Which version of processing should be used to make it compile without error?

Needs v2.2.1 of Processing.

Details here:
https://github.com/euphy/polargraph/wiki/Running-the-controller-from-source-code
Or in the readme.txt that's in the zip,

I'm not clear what the thing going wrong here is - I can see there's some exceptions thrown. Does the app run?

I got the precompiled versions to run, so I haven't tested this any further.

Hi there! I'm new here and this is my first post!

I'm having the same NullPointerExceptions that mskogly is having and I might have found out why:
-The file processing-source\polargraphcontroller\default.properties.txt

controller.vector.filename=C\:\\Users\\sandy_000\\Documents\\Processing\\polargraphcontroller\\data\\midsquare.svg

controller.image.filename=C\:\\Users\\sandy_000\\Documents\\grace-kelly-375x470.jpg

Those two files are missing and the path needs to be changed.

The midsquare.svq user path needs to be fixed to your own settings; in my case :
controller.vector.filename=C:\\Users\\Ruiji-Sama\\Documents\\Processing\\polargraphcontroller\\data\\midsquares.svgg

Still trying to figure out where the image is supposed to show up. will post results soon

Ok, so the controller.image.filename is the image that's loaded into the controller when it starts up.

I fixed the nullpointer by adding a basic image in the folder and editing the path in default.properties.txt.

controller.vector.filename=C:\\Users\\Ruiji-Sama\\Documents\\Processing\\polargraphcontroller\\data\\midsquares.svgg

controller.image.filename=C:\\Users\\Ruiji-Sama\\Documents\\Processing\\polargraphcontroller\\data\\images.jpg

This fixed it for me, got no more NullPointerExceptions

The app still compiles and runs fine when it can't find the file - on windows anyway. The exception is shown in the console, but it doesn't stop execution.

Of course in truth it's a mistake to have left the default.properties.txt file in the bundle!
