So, let's start by creating a simple perception system in which we print on the screen when something enters or leave the perception field of the AIs, along with the number of currently seen objects (including/excluding the one that just entered/exited).

Once again, we will do this twice, once with Blueprint and another time with C++, so that we can get to know about both methods of creation.

First of all, we need to create a new AI controller (unless you want to use the one we've already been using). In this example, I'm going to call it "SightAIController...
