Hi everyone there,
I am trying to work with the advanced example of this addon.
I am trying to control with the audio input a shape that I create with a vector of random points.
So ideally instead of controlling the mesh vertices I should control the random shape vertices.
I am a bit stuck for few reasons.
I am not sure what is the meaning of the & when you build a vector.
(e.g., vector & vertsOriginal;)
I get this error :
‘reference to type of Point requires an initializer’ and I think it’s connected with the & but can’t figure out how.
I am not sure what would be the equivalent of getVertices of the ofMesh for controlling the random shape vertices
That’s called a reference in C++. An english translation of the case you mention above would be “vertsOriginal is a reference to a vector”.
So in code, if you have something like:
int a = 5;
int b = a;
You end up with two ints, a and b, and they both equal 5. b is just a copy of a.
But in this case:
int a = 5;
int& b = a;
You only have one int (a), and a reference to the same int (b). If you were to do:
b = 10;
afterwards, the int “a” would also be 10, since a and b both refer to the same int.
Your error is probably due to the fact that a reference has to refer to something right when it gets created. You can’t just do int &b; and then decide what b refers to afterwards.
