Control Structures in My Game

What Are Control Structures?

Control structures are statements that control the flow of a program.

They decide:

  • what code runs
  • when code runs
  • how often code runs

The main types include:

  • if statements
  • loops
  • switch-like logic (in some systems)

Why Control Structures Are Important

In games, control structures are used to:

  • detect collisions
  • control enemy behavior
  • manage scoring
  • check win/lose conditions
  • handle player input

Without control structures, the game would run in a fixed, unresponsive way.

Example 1: Collision Check (if statement)

My game uses if statements to detect collisions.

if (dist < 40) {
  if (!this.gameEnv.elonHitCooldown) {
    this.gameEnv.gameScorer.deductPoints(10);
  }
}

Explanation

This control structure:

  • checks distance between objects
  • ensures cooldown is not active
  • applies damage (score deduction)

It only runs when conditions are true.

Example 2: Preventing Negative Score

Control structures also prevent invalid values.

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

Explanation

This ensures:

  • score never goes below zero
  • game values stay valid

This is a simple decision-making structure.

Example 3: Looping Through Enemies

My game uses loops to check all enemies.

for (const enemy of enemies) {
  const dx = enemy.position.x - this.position.x;
}

Explanation

This loop:

  • goes through every enemy
  • calculates distance to each one
  • helps determine which enemy is closest

Loops are essential for managing multiple objects.

Example 4: Finding the Nearest Player

Control structures are used in AI behavior.

let nearest = players[0];
let minDist = Infinity;

for (const player of players) {
  if (dist < minDist) {
    nearest = player;
    minDist = dist;
  }
}

Explanation

This logic:

  • compares distances
  • finds closest player
  • updates enemy target

This is used in enemy AI movement.

Example 5: Early Exit Conditions

Some control structures stop code early.

if (this.isKilling) return;

Explanation

This prevents:

  • unnecessary updates
  • broken behavior
  • wasted processing

Early exits make code more efficient.

Why Control Structures Help My Game

Control structures improved my game by:

  • controlling game logic flow
  • managing enemy AI behavior
  • handling collisions
  • improving performance
  • making decisions inside the game

Without them, the game would not respond dynamically to player actions.
