I havent seen the video but you can use Get Random Point in Navigable Radius or Get Random Reachable Point in Radius functions should help.
Hi, my name is Troy and I am trying to make an A.I patrol between two points, like on this video Unreal Engine 4 Tutorial : AI Patrol (AI pt2) - YouTube, but at 10:44 I could not set the patrol points to target points.
also I was trying to get my A.I to patrol to random points using get random point like on the first part of the video.
But I could not find the get random point, i tried creating random vectors but that did not seem to work.
I need an answer quick, because this is for a school project and I don’t have much time left so an answer other then "Have you tried searching for the answer first? From the top of my search results: 1 2 3 4
