  1. Use of Super

Vehicular Combat Game example

ere is an example of using the super keyword in the context of a vehicular combat game in JavaScript:

class Vehicle {
  constructor(x, y) {
    this.x = x;
    this.y = y;
    this.health = 100;
  }

  move(x, y) {
    this.x = x;
    this.y = y;
  }

  attack(target) {
    target.health -= 10;
    console.log(`${this.constructor.name} attacks ${target.constructor.name} for 10 damage.`);
  }
}

class Tank extends Vehicle {
  constructor(x, y, turretX, turretY) {
    super(x, y);
    this.turretX = turretX;
    this.turretY = turretY;
  }

  attack(target) {
    const turretDistance = Math.sqrt(Math.pow(target.x - this.turretX, 2) + Math.pow(target.y - this.turretY, 2));
    if (turretDistance <= 5) {
      super.attack(target);
    }
  }
}

class Helicopter extends Vehicle {
  constructor(x, y) {
    super(x, y);
    this.minAltitude = 10;
    this.maxAltitude = 100;
  }

  move(x, y) {
    super.move(x, y);
    console.log(`${this.constructor.name} flies to (${x}, ${y}).`);
  }

  changeAltitude(altitude) {
    if (altitude >= this.minAltitude && altitude <= this.maxAltitude) {
      this.y = altitude;
      console.log(`${this.constructor.name} changes altitude to ${altitude}.`);
    }
  }
}

const tank = new Tank(0, 0, 5, 5);
const helicopter = new Helicopter(10, 10);

helicopter.changeAltitude(50);
// Output: "Helicopter changes altitude to 50."

helicopter.move(5, 5);
// Output: "Helicopter flies to (5, 5)."

tank.attack(helicopter);
// Output: "Tank attacks Helicopter for 10 damage."

helicopter.changeAltitude(200);
// Output: "Altitude out of range."

In this example, the Vehicle class has a constructor that accepts an x and y position, and sets the initial health of the vehicle to 100. It also has move and attack methods. The move method sets the position of the vehicle to the specified x and y coordinates, and the attack method reduces the target vehicle's health by 10.

The Tank class extends the Vehicle class and adds a constructor that accepts x, y, turretX, and turretY coordinates for the tank's body and turret. It also overrides the attack method to check the distance between the target and the turret before attacking. If the distance is 5 or less, the tank can attack the target using the super.attack method to call the attack method of the helicopter.?
