Tripwires Module

The Tripwires module allows configuring different tripwires in the Solution, that can be used in the instances for multiple purposes.

When a Tripwire configuration is defined for the solution, its configuration window will be available at the Input configuration window.

Tripwires Configuration

A tripwire defines a line where data will be stored on the number of objects that cross the defined zone points, after calling tripwireInst:checkTripwires() on the Lua code.

To add a new tripwire to the instance add the line points to the corresponding tripwire tab on the Input configuration Window by clicking on the desired point locations while holding the Ctrl key, after setting all the desired points, the new tripwire will be saved by clicking outside the line without the Ctrl key pressed.
