Field types

Fields are the underlying data elements of each object in your script. Each is validated in a different way.


A simple true or false value.


A color, in hexadecimal format. (i.e. #FFFFFF)


Latitude/longitude coordinates.


An offset of time indicated in a brief shorthand of number and unit. For instance, "10s" for ten seconds, "3.5h" for three and a half hours, or "-40m" for minus forty minutes. Negative offsets indicate a period prior to another time.


An email address. For example, "".


A field allowing a choice between a limited set of values. The specific set of options will be different for each field and documented in that field.


A simple integer value: 0, 100, -50, etc.


A geocodable address, including city, state and ZIP/postal code.


A machine-readable name used for looking up variables. Only letters, numbers, dashes or underscores are allowed. For example, date, or num_points. Periods may be used to look up children of data dictionaries: for example, or current.directive. Specific values can also be specified here by including the text in double quotes: the lookup red will look up the contents of the variable "red", whereas the lookup "red" will return the text value "red". Numbers like 1, 400, etc, can be used, as can the values true and false.


Text styled with markdown. See for help on how to use markdown.


Uploaded media: an image, video, or audio clip.


An integer or number with a decimal.


A reference to the name of an element in the script.


Arbitrary text, usually for display to a participant.


A shorthand clock time, as defined in days relative to the start of the experience. For instance, 3:00pm means 3pm the day of the experience. 5:30am means 5:30am the day of the experience. +1d 4:15pm means 4:15pm the day after the day the experience started.


A field that can be a string, number, or "true" or "false".
