The direction rule detects objects moving in a specific direction.
Configure the direction and acceptance angle by moving the arrows on the direction control widget.
The primary direction is indicated by the large central arrow.
The acceptance angle is the angle between the two smaller arrows.
Objects that travel in the configured direction (within the limits of the acceptance angle), through a zone or over a line, trigger the rule and raise an event.
The following image illustrates how the white car moving in the configured direction triggers the rule whereas the other objects do not.
