With characters rendered out in their corresponding positions, it is time we determine whether or not our player and characters are colliding. This is step one in the process of prompting a conversation—before we actually pop up a dialogue box, we need a way to tell who we're colliding with so we know what speech to use.

Similar to detecting for collision with our map boundaries, we need to loop through each of our characters, then run collision detection code between them and our player.
