The link seems to have broken for the last video so here is a link to it:
Moving on from the player character I have now added enemies into the game which chase the player character around and can be shot. This is the main purpose of the game and where the fun is had. At the moment though the game is a bit buggy with the zombies not always being destroyed when hit as well as when they are destroyed the actual game object is destroyed which means no more enemies are spawned breaking the game. Another issue currently is that the zombies are very simple they only have one behaviour which is to pursue the player whilst this is fun for a while it gets repetitive and therefore boring very quickly. Here is a video of how the zombies behave currently
As you can see in the video the zombies spawn in initially but then as the first few are destroyed they all dissapear.
