java.lang.IllegalArgumentException

Hi,

I was trying out the spirograph example and when I add a copy node and connect the output of the reflect node to the copy node I get the following error.

There are two reflect nodes: one works just with numbers (the greenish one) and one that works with geometry (the black one). You've probably selected the wrong one. (in general, black nodes need to be connected to other black nodes)

The type of a node is quite important. NodeBox will try to convert between types, but in this case the two nodes do different things, even though their names are equal.

You can read more about types and type conversion on our "How NodeBox Works" page.
