# Survival Game Example

Here is an example of getters and setters in the context of a hypothetical survival computer game:

```javascript
class Character {
  constructor(name, health, maxHealth) {
    this._name = name;
    this._health = health;
    this._maxHealth = maxHealth;
  }
  
  get name() {
    return this._name;
  }
  
  set name(newName) {
    this._name = newName;
  }
  
  get health() {
    return this._health;
  }
  
  set health(newHealth) {
    if (newHealth > this._maxHealth) {
      this._health = this._maxHealth;
    } else {
      this._health = newHealth;
    }
  }
  
  get maxHealth() {
    return this._maxHealth;
  }
  
  set maxHealth(newMaxHealth) {
    this._maxHealth = newMaxHealth;
  }
  
  heal(amount) {
    this.health += amount;
  }
  
  damage(amount) {
    this.health -= amount;
  }
}

class Player extends Character {
  constructor(name, health, maxHealth, inventory) {
    super(name, health, maxHealth);
    this._inventory = inventory;
  }
  
  get inventory() {
    return this._inventory;
  }
  
  set inventory(newInventory) {
    this._inventory = newInventory;
  }
  
  useItem(item) {
    // use the item
  }
}

const player = new Player("Bob", 100, 100, []);
console.log(player.name); // "Bob"
console.log(player.health); // 100
console.log(player.maxHealth); // 100
player.heal(20);
console.log(player.health); // 100
player.damage(90);
console.log(player.health); // 10
player.inventory = ["medkit", "water bottle"];
console.log(player.inventory); // ["medkit", "water bottle"]
```

In this example, we have a base `Character` class that represents any character in the game with a name, health, and max health. The `Player` class extends the `Character` class and adds an `inventory` property. We have defined getters and setters for all of these properties, allowing us to control how they are accessed and modified. The `heal` and `damage` methods use the setter for the `health` property to ensure that the character's health never exceeds their max health. The `Player` class also has a `useItem` method for using items from their inventory.
