TIME-BASED SCRIPT SEQUENCES

摘要

A system for synchronizing the execution of arbitrary sequences of code to units of time is disclosed. The system contains means for playing media, such as displaying full-motion video or animation sequences on a computer monitor or playing a sequence of audio through a speaker connected to the computer. The system is capable of executing a script sequence, such as a sequence of commands in a scripting language. The system also contains means for generating a sequence player object for keeping track of time during the execution of the script. The system also contains means for generating at least one tagged object which has a tag for associating the tagged object with the sequence player object. The system discloses means for jumping to an arbitrary point in a time-based script sequence, means for rewinding in a time-based script sequence, and means for generating a key frame script in a time-based programming environment.
