The event trigger in the scene. The sensor allows you to select scene objects by a given volume or ray.

For a good overview of sensors, you can take a look at the 'Sensors.scene' file, which can be found in 'Assets\Samples\Starter Content\Scenes'.


The parameter 'Source Data' indicates what type of objects will be determined: scene objects or physical bodies.

In order to see which objects the sensor has selected, you need to enable the 'Display Objects' parameter.


Use Objects property to get current list of the affected objects.

Use ObjectEnter and ObjectLeave to get updates of the affect objects, or override OnObjectEnter and OnObjectLeave methods in a derived class.

To refine the filtering, you can create a handler for the FilterObjectEvent event, or override the OnFilterObject method in a derived class.
