Function:

The uTimerScript application allows the user to script a set of pre-configured posts to a MOOSDB. In its most basic form, it may be used to initialize a set of variables to the MOOSDB, and immediately terminate itself if a quit event is included. Additionally, uTimerScript may be used with the following advanced functions: (1) Each entry in the script may be scheduled to occur after a specified amount of elapsed time. (2) Event timestamps may be given as an exact point in time relative to the start of the script, or a range in times with the exact time determined randomly at run-time. (3) The execution of the script may be paused, or fast-forwarded a given amount of time, or forwarded to the next event on the script by writing to a MOOS variable. (4) The script may be conditionally paused based on user defined logic conditions over one or more MOOS variables. (5) The variable value of an event may also contain information generated randomly. (6) The script may be reset or repeated any given number of times. (7) The script may use its own time warp, which can be made to vary randomly between script executions. In short, uTimerScript may be used to effectively simulate the output of other MOOS applications when those applications are not available.
