Question on Detection Script
The Detection Script in the downloaded "Detection.unity" Tutorial Scene is generating the Console Warning shown below. It can be assigned to and adjusted within the Enemy Players' Component window, but the Viewing Radius/Angle and color are not visible in the Screen window. The script appears to be identical to that shown in the video, but I may be missing something, or maybe recent updates necessitate minor script changes. If you have a fix please let me know. Thank you.
