[Hgengine-devs] Finding Nodes

[Charles L. <ch...@cn...>]

Devs,

I'm looking into adding a way for nodes to be indexable globally and
locally.

In HG1, we were able to say OBJECTREGISTER.GetObjectByName(
"MyCameraControl" );  And it would return a pointer to the object
"MyCameraControl." Also, we were able to, if need be, get a list of all
of the objects.

In HG2, I feel like it would be useful to be able to have the same
functionality there.  Maybe, all objects could be indexed by name.

Also, HG2 could have an additional feature (This is actually what I want
first):  Another function, to say GetChildByName( "NameOfObject" ); That
could search a current node's children and its children's children for
that node.  This function could/should be asymptotically slower than the
overall object register.

This would leave us to implement two things:

1) OBJECTREGISTER (using an std::map<> or an MHash)
2) GetChildByName function added to MercuryNode.

I could implement both.

My only concern with #1 is it does add to the overhead of objects if
they have to register with some central command, so-to-speak.  We could
avoid this by making it so only named objects register with
OBJECTREGISTER.  This does remove the feature of being able to get a
list of all objects, but I am not really sure what the right tradeoff
here is...
