Using the visual training builder, user can add variables of the following types:
String Variable<\/strong>: Stores object names, message data, ..etc
Number Variable<\/strong>: Supports both integer and float numbers, can be used for counting, and storing\/calculating values
Time Variable<\/strong>: can save the time at any stage of the VR experience<\/p>\n\n\n\n

String Variable<\/h2>\n\n\n\n
\n
\n

Initial value <\/strong>can be set to any string in the variable editor in training builder.
When used in Change Variable<\/strong> response, string should be surrounded in single quotations ( ‘<\/strong> )

Expression supported operations <\/strong>include adding strings, and substring<\/p>\n<\/div>\n\n\n\n

<\/p>\n<\/div>\n<\/div>\n\n\n\n

Time Variable<\/h2>\n\n\n\n
\n
\n

Initial value <\/strong>all time variables are set to the start time of the VR experience.
At any point of the VR experience the user can capture current time and store it in a time variable<\/p>\n\n\n\n

More info about using time variables can be found in the post Timing processes in VR<\/a><\/p>\n<\/div>\n\n\n\n

\n
\"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n

Number Variable<\/h2>\n\n\n\n

Initial Value can be set to any float or integer numbers
The following operations are supported for number variables
Increment<\/strong>: Adds one to the current value
Decrement<\/strong>: Subtracts one from the current value
Time Difference<\/strong>: calculates the different in seconds (up millisecond precision) between two time variables
Expression<\/strong>: large number of expressions are supported we will discuss those in a new article to be published soon. <\/p>\n\n\n\n

\n
\n

Variable Writer <\/h2>\n\n\n\n
\n
\n

Variable writer tool enables the user to track the value of a variable in the VR experience<\/p>\n\n\n\n

The value of the variable is updated dynamically, so whenever the variable value is changes the variable writer will be updated to show the new value of the variable<\/p>\n\n\n\n

Variable writer is available under the VR effect menu.<\/p>\n\n\n\n

The user can control its size, and place. So it to be aligned on a wall in the scene or on a monitor<\/p>\n\n\n\n

User selects which variable to view, color of the text, and prefix text.
<\/p>\n<\/div>\n\n\n\n

\n
\"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n
\n
\n

Having multiple variable writers belonging to the same group makes them have the same font size.<\/p>\n<\/div>\n\n\n\n
