You can get and set the tuple. You want a getX() and a setX()? what is the

Alex,
MMORPGs are still a dark art. There are a lot of factors that have to be
dealt with and it's a huge undertaking for a "garage band" programming
group. A simple multiplayer game is a different story. They can easily be
implemented with either client-server or peer-to-peer communications.
Is this possible?

Hello,
After the scene has been made "alive" (is attached to the locale) you
can only add a BranchGroup to that live scene (and the parent's
ALLOW_CHILDREN_EXTEND capability must be set). This means you can add
anything as long as the top most node is a BranchGroup. Example:

In general it does, but I've had a few weird bugs with it. The one I see
