Hello,
A quick question on vector asssignment using openvrml. I have a
javascript function where I am dynamically changing the key values of a
position interpolator, but the assignment does not seem to work.
I have tried
PosInter.keyValue[1][0] = targetPosition[0]; // x
PosInter.keyValue[1][0] = targetPosition[1]; // y
PosInter.keyValue[1][2] = targetPosition[2]; // z
and also
PosInter.keyValue = [0 0 0, targetPosition[0] targetPosition[1]
targetPosition[2]];
but both don't work.
cheers
Cherian

a typo, presumably. :-)

First off, you need to be using directOutput TRUE in order to set the
node field like this.
But assuming you've done that, I think this still doesn't work because
you end up setting the elements of a temporary SFVec3f that keyValue[1]
returns. I think there's an argument to be made that this syntax should
work; but I haven't found a good way to do that with SpiderMonkey.
It should work to set the entire SFVec3f element at once:
PosInter.keyValue[1] = targetPosition;

MF* types are not JavaScript arrays; so I wouldn't expect that to work.

Hello Braden,
The problem seems to be occurring when the field of an
external node is changed in a script node. I have attached an example where
I try to toggle between the binding of two viewpoints from a script. The
bind values remain unchanged when using simple assignment.

Hi Braden,
Sorry about this. Figured out why it didn't work. Then tried to
edit the post but couldn't.
