Distance

The Distance trigger uses parameters for units of measure and distance to test if the object with the behavior is within a certain distance of a second, selected object. 

For example, if Measurement is set to Feet and Distance is set to 21, the trigger event will happen as soon as the object defined by Object Selection is within 21 feet of the selected object.

Object Selection

Presents a list of all stage objects.

Measurement

Displays units in inches, feet, yards, centimeters, and meters. The default Measurement value is Yards.

Distance

The distance between the object with the behavior and the object chosen with Object Selection at which the trigger will occur.
