Methods & Parameters in My Game

What Are Methods?

Methods are functions that belong to classes or objects.

Methods allow objects in a game to:

  • move
  • update
  • interact
  • perform actions

In my game, methods are used for:

  • collecting coins
  • enemy movement
  • scoreboard updates
  • collision systems
  • rendering behavior

What Are Parameters?

Parameters are pieces of data passed into methods.

They allow methods to work with different values.

Example:

move(direction, speed)

Here:

  • direction is a parameter
  • speed is a parameter

Parameters make code flexible and reusable.

Example 1: collectCoin Method

One method in my game is collectCoin().

collectCoin(points = 10) {
  this.coinsCollected++;
  this.score += points;
  this.updateDisplay();
}

Explanation

This method:

  1. increases collected coins
  2. adds points to the score
  3. updates the scoreboard

The parameter:

points = 10

allows different coin values to be added.

Example 2: deductPoints Method

Another method in my game removes points.

deductPoints(points = 10) {
  this.score -= points;

  if (this.score < 0) {
    this.score = 0;
  }

  this.updateDisplay();
}

Explanation

This method:

  • subtracts points
  • prevents negative scores
  • updates the scoreboard

The parameter points controls how many points are removed.

Example 3: Enemy Update Method

Enemies use an update() method.

update: function () {

  const players = this.gameEnv.gameObjects.filter(
    obj => obj.constructor.name === "Player"
  );

}

Explanation

The update() method runs repeatedly during gameplay.

It allows enemies to:

  • detect players
  • move toward the player
  • react during the game

Methods make enemy behavior dynamic.

Example 4: Collision Detection

The player also uses methods for collisions.

if (dist < 40) {

  if (!this.gameEnv.elonHitCooldown) {

    this.gameEnv.gameScorer.deductPoints(10);

  }
}

Explanation

This logic checks:

  • distance between objects
  • whether damage cooldown is active
  • when to deduct points

Methods help organize collision systems cleanly.

Why Methods & Parameters Are Important

Methods and parameters helped my project by:

  • organizing game logic
  • making code reusable
  • reducing repeated code
  • allowing flexible behaviors
  • simplifying updates and debugging

Without methods and parameters, the game systems would be much harder to manage.
