Mark's update - Week 6

This week I focused on adding physics interactions with the pinatas and other movable objects in the scene. For this, I used Unity's AddExplosionForce method. This will also be used for the tootsie bomb code. Physics interactions are very important for the gameplay feel because these days the average player expects to be able to knock stuff around if they have a melee weapon.

I also added a simple health bar. We can change the skin and stuff later but for now it works.

Also, I added a piece of code that makes it so that when the zombies are chasing you and you get far enough  away they lose interest and go wander.
