Methods and systems of simulating dynamic properties on computer-implemented
objects that do not support dynamic properties are described. In one embodiment,
one or more first objects that do not support dynamic properties are provided.
One or more second programmable objects are provided and are programmed to effect
property value changes on the first objects. The programmable objects can be programmed
using data structures that, in one embodiment, comprise an array of one or more
sets of data structures. Each data structure set is associated with a property
whose value is desired to be changed. The data structure set can define a new property
value, a time at which the property value is to be changed, and how to effect the
property value change. The programmable object(s) is pre-programmed with the data
structures and knows when to call the first objects so that they can change their properties.
