Yea, that would be useful. > * If you click some mouse button on an object it becomes selected > * In the future, could show a panel to edit properties of selected > object, or create new objects attached to it in scenegraph fashion, or > whatever How do you differentiate between "I'm clicking on this to activate it" and "I'm clicking on this to edit its properties"? > * If a selected object has the "ui:actions" type that I added recently, > then display those in a side panel as buttons I'll have to take a look at it -- sounds like a generalization of misc:clickable perhaps? So instead of "I can accept click messages" you say "I can accept messages X, Y and Z" and specify that "X" is the default message for clicking. > * Some way to show/hide sets of objects in the world, or change their > properties together as a group (e.g. alhpa to make them fade in and > out).

This sounds kind of complicated, although I agree it could be useful. Actually, my plans for a redesign of A3DL (for s5) will specifically include a concept of layers, so unless you want to code layers as a server-side behavior (where you can select which layers to show, and the hidden ones are removed from the sector) it might be better to wait on that. Let me also point out that you probably shouldn't kill yourself with crazy new ter'angreal features; the only reason I'm working on it is to have something shiny and polished enough to demo as a stepping stone to solicit funding for s5 development. There are systemic flaws in the CS plugin (due to multithreaded race conditions that are very hard to debug, which is what prompted the whole concurrency discussion and overhaul for s5) that make it unsuitable for anything other than a demo. > > - Added an "<addtype>" directive under the <load> section in XOD files, > > so objects from loaded files can be extended. > > Ah, useful.

The "grab" feature is kind of a hack at the moment. It was intended as a quick-and-dirty way of showing that you could interact with anything in your environment, not a real authoring tool. > I think the Blender approach is a good one btw, where most commands are > single keystrokes you can hit with your left hand while you mouse with > your right (or vice versa).

Do you mean commands for original authoring, or commands to be used in an interactive session to communicate with other users? The former (authoring) I don't think we should focus on too much, our time is better spent working on supporting popular modeling programs and 3D file formats than it is on allowing modeling/authoring within ter'angreal itself. Commands to modify the environment which may be useful in a multiuser scenario to assist in communication are a different story, and that's worth thinking about. -- [ Peter Amstutz ][ [EMAIL PROTECTED] ][ [EMAIL PROTECTED] ] [Lead Programmer][Interreality Project][Virtual Reality for the Internet] [ VOS: Next Generation Internet Communication][ http://interreality.org ] [ http://interreality.org/~tetron ][ pgpkey: pgpkeys.mit.edu 18C21DF7 ]
