Scripting revision..

Having used javascript to a degree in my previous projects I was fairly familiar with how I wanted the game to work. I looked back at my previous scripts and decided I would have to add additional scripts. I decided to review the unity website for reference.

The tag system built into unity allows me to tag an object with a label, to allow me to reference them through the scripts.

Colliders are used to detect when objects collide. They can be applied in variety of shapes, from boxes, spheres, capsules or even to a mesh of an object. I used these in previous projects mainly for the combat system. A typical scenario would involve two colliders colliding to trigger the health of the player to decrease, or increase when collided with a med kit. This will be used for our combat and health system, but without the scripts these functions will do nothing.
An example of a mesh collider being added to the scene geometry:

Collider.OnTriggerEnter is needed in the script to detect the collision of the collider attached to the enemy. Here is Unity's reference to the code:

 CharacterController.OnControllerColliderHit is used on the player as it uses a character controller to move the character around the scene. Here is Unity's reference to the code:
