Basic Senses is used to detect Audio Aspects and Visual Aspects in your Unity scene. This is done by adding Visual and Audio Sensors to your AI and using them through the Detect node.

Once you have added a sensor, you can select it by left clicking on its title bar. You can select multiple sensors by holding the Ctrl key down.

You can also move, rotate, and scale any selected sensors by using the transform tools.

You can also change a visual sensors effective area by modifying its Horizontal Angle and Vertical Angle. This allows you to create cone and semi circle sensors instead of spheres.
