Events

Events are changes in the virtual world. They are generally associated with a time, a place, objects, and may be of several kinds. Not all events need to be noted, but for tracking purposes or reconstruction purposes, it may be useful to follow them.

Possible attributes of an object might be removable, and non-removable.
The addition and creation of objects, changes in their properties, and changes in the properties of space are some of the possible events. These are simple events, but more complex events involving multiple objects, attributes, positions, and times are also possible. For now, I want to keep them simple.

With the elements so far considered, it's possible to consider part of a game of tic-tac-to, with Xs and Os as non-removable objects. I haven't yet considered turn-taking victory conditions, or strategies of play, but it's possible to construct the mechanics of play in at least a crude form. There are a few others of this type. Most interessting games and universes, though, require the next feature I want to consider...movement.

I've been looking at the history of computer games, and when I have more time, I'd like to consider some of these as adding important elements to the possibilities of
Virtual World Building.
