Following the agent

We want our Agent to follow its leader agent in whichever direction it goes. While still following the other logic to bounce off walls and the movement behavior we plan to introduce, we will create an example showing how this will affect the agent's movement as follows:

This step requires us to create a few variables and one function. We want to hold our Follower and Leader actors when operating in a free setup. We also need LeaderDirection to hold the direction that the agent should be moving in. Lastly, we can mark agents to be followers or leaders by enabling or disabling a Boolean called isLeader.

With these variables, we can keep track and prevent leaders from following followers, which can create interesting movement behavior but not what we intend to make happen in this demonstration.
