Re: [FreeWRL-develop] Touchsensor Proto in Proto

[doug s. <hig...@ho...>]

John,
Thanks for your suggestion about add_parent.

I checked in a change that seemed to work; all the diff is in one spot in OpenGL_Utils.c about L.3080.

FIXED - freewrl now sensitizes the box like the others (and cylinder still not seen or sensitized, like a few of the others, and still not sure if that's correct.)

> Freewrl doesn't sensitize the Box likely because it doesn't have code to propagate sensor sibling association through the Proto wrapper.

STILL SEEN AND SENSITIZED (still not sure if that's correct, it's different than the others)
> Box: they all showed the Box, not sensitized
