Issues with gen~ codebox functions in rnbo

I am having trouble implementing gen~ codebox code that works fine in Max in RNBO. I think it would be very helpful if there was a list of thing that do not work generally and I wanted to see if anyone else was having these issues as well.

Here is the current state of the gen code I am trying to get working:

Here are some I have run into:

• declaring data structures inside of functions causes a compilation error:

wallBounce(i, dt, rc, cut){
    Delay d(samplerate*5);
    dt = mstosamps(dt);
    o = d.read(dt);
    d.write(i);
    if (cut > 0){
        o = onepole(o,cut);
    }
    return o*(rc);
    }

• when working around this issue (using a Data external to the function) the code will compile, but will not work in RNBO as expected (does work in Max). (in the version above)
