The goal is for all gbAnimator objects (node and links) to be able to collide with
one another. At this time, the only vertical and horizontal links are recognized
by gbAnimator as barriers. I'm actively working the feature and hope to complete
it before the end of Feb, 2006.
To turn a link into a barrier, simple select the link and set the "Use as Barrier"
link property. A barrier link will be display as a thick red line (when selected,
a link uses a thin blue line, so you'll have to de-select a link to see the thick
When using a barrier it is normal, but not a requirement, to lock the end points
so that the barrier remains where you've created it (or moved it).
As a convenience for creating more complicated barriers, gbAnimator provides a
"Convert Object to Barrier" toolbar button. This will convert all links, within
the currently selected object, to barriers. It will also lock all nodes within
I'm sorry to report that the barrier features in place have some limitations.
If node speeds go too high the barrier will not stop them. This is a problem
with the algorithm I use and I hope to fix it along with implementing the
full barrier solution later this month.
