2D platform engine in unity part 13 - Tagging and Rushing

In tonights short coding session I added two new components.

A tagging system for entities.
Unity already has a way to add a tag to gameObjects, but for me “tagging” means being able to add several tags to an object, which Unity does not support. Something can be tagged both as NPC AND a Human.

Second, I added a new (very simple) AI-component that will rush towards player or NPC if standing in front of it.
It utilises the tagging system to get a list of all entities tagged as either “player” or “NPC”, check direction and distance, and start charging!

As you can see, the Hedgehog speeds up if either NPC_Joey or the player is in front of it (although the graphics does not flip correctly yet).
