# - AMZN_GetTimeFromFrame
|
|
# Takes frame number as input
|
|
# Returns time based on current Maya settings

# PURPOSE: To return the current time from a given frame
|
|
#
|
|
# PROCEDURE: Using C++ api calls, create new MTime entity
|
|
# Set the MTime entity to the current unit of time and current frame
|
|
# returns the current time in secconds
|
|
#
|
|
# PRESUMPTIONS: original c++ used MTime.as, which does not currently seem to be supported in Python
|
|
# looks like MTime.asUnits is equivalent function
|

|
# PURPOSE: To parse out the string containing the animation export options
|
|
#
|
|
# PROCEDURE: First we split the string up via it's sentinal value " - ", then we take the first
|
|
# element, which is the frame range, and pull out the start and end frames. We then
|
|
# add them all back into one string
|
|
#
|
|
# PRESUMPTIONS: 1) the items in the string are seperated by an " - " value
|
|
# 2) that there are no " - ' values in things lke path names (wasn't my idea for a sentinal value)
|
|
# 3) that the first element in the string is the time range in the format [startFrame-endFrame]
