Ordered systems: Humanization

February 7, 2010

From looking at the GDC paper on Bungie’s modular meta-data approach I think i can simplify this down to something like:

system.Element

For example leg.upper.twist.1 so that ‘leg’ is the system and ‘upper’ as an element of that system. Systems themselves still have attributes, but also contain .elements. Elements in turn have .name, .node, .system (which refers back to the system there part of).

I think this may take on the form of a pseudo XML/HTM tag based approach:- list.element with attributes list.elements element.list, element.name etc..

Ordered systems: properties

As with an object existing as an index of a system, additional nodes, assets etc may affect the system directly or indirectly. For these the only reference thats needed is the system itself e.g.

011 = Root
011-21 = upperLeg
011-22 = lowerLeg
011.property[1] = polevector

This is very rough atm, and currently called a ‘property’ of the system. Anything can be a property of a system including, nodes, controllers, values – it’s just something thats related to the system.

Im assuming we can ask an object/controller/value etc if its the property of a system with x.isProperty returning the systems index its connected to.

Properties just aid the system – there created when the system is created. E.g if my system is a leg, a property in the form of a poleVector may get created. And this may be based on custom information with the system when its saved like “poleVector=True” etc.

Properties are what control the system, and there what get saved I’m assuming if we need to save animation.

How this animation is stored is something I’m not sure about – it would be a transform matrix, but whether it would be the transform relative to the system itself, character, base or the world i don’t know.

The interesting thing with this approach of
parent-system-index|property is that it can work with agile scrum type tracking.

A character maybe a system, with a set of indices denoting steps in its creation. eg.

project X|Assets|Characters|
project X|Assets|Characters|-|PlayerMale|Model
project X|Assets|Characters|-|PlayerMale|Model|-|Mesh|lowRez
project X|Assets|Characters|-|PlayerMale|Animation|-|ambient|aa

With properties of playerMale being ‘name’, ‘role’, ‘height’ etc..
