Ray Sensor

Ray sensor

The Ray sensor shoots a ray in the direction of an axis and sends a positive pulse once it hits something. It can be filtered to only detect objects with a given material or property.

See Sensor Common Options for common options.

Special Options: It shares a lot of buttons and fields with Radar sensor.

Property

This field can be used to limit the sensor to look for only those objects with this property.

Notes

1) Unless the Property field is set, the Ray sensor can detect objects "through" other objects (walls etc).

2) Objects must have "Actor" enabled to be detected.

Axis

This menu determines the direction of the ray. The ± signs is whether it is on the axis direction (+), or the opposite (-).

Range

Determines the length of the ray. (Blender units).

X-Ray Mode button

Makes it x-ray, so that it sees through objects that don’t have the property or material specified in the filter field.
