The Health System makes it easy to not just set up destructible vehicles and objects of all kinds, but also create damageable parts on a bigger vehicles, such as capital ships.
The core components of the Health System are:
A Damageable component represents an object which can be damaged (or healed). This component has a specified 'Health Type' you can set in the inspector, and has a health value which can range from zero to a specified maximum value.
Add a Damageable component for any object (or part of a vehicle) that you wish to be damaged by weapons or collisions.
When a weapon such as a projectile or a beam hits a damageable object, it searches for a Damage Receiver component on the same game object as the collider. This enables it to efficiently pass damage (or healing) information to the Damageable that the collider represents.
Add a Damage Receiver component to the game object of every collider representing a Damageable object.
The Damage Receiver is basically a channel for passing damage (or healing) information through the collider to the Damageable.
Health Modifiers are added to bullets, missiles, explosions or anything else that is capable of damaging something.
