Booleans in My Game

What Are Booleans?

Booleans are values that can only be:

true

or

false

Booleans are used to control logic and decision-making in programs.

Games use booleans to track:

  • collisions
  • enemy states
  • cooldowns
  • player conditions
  • game events

My game uses booleans throughout many gameplay systems.

Why Booleans Are Important

Without booleans, the game could not:

  • check conditions
  • control enemy behavior
  • activate cooldown systems
  • prevent repeated actions
  • manage game states

Booleans help the game make decisions.

Example 1: Collision Cooldown

My game uses a boolean to prevent repeated enemy damage.

gameEnv.elonHitCooldown = false;

Explanation

This boolean tracks whether:

  • the player can currently take damage
  • cooldown is active or inactive

If the value is:

  • true → cooldown is active
  • false → player can take damage again

Example 2: Checking Boolean Conditions

The game checks booleans using conditionals.

if (!this.gameEnv.elonHitCooldown)

Explanation

This means:

if cooldown is false

The game then:

  • allows damage
  • deducts points
  • activates cooldown

Example 3: Enemy State Tracking

Enemies use booleans to control behavior.

if (this.isKilling) return;

Explanation

The boolean isKilling determines:

  • whether enemy actions should stop
  • whether updates should continue

If isKilling is:

  • true → stop updating
  • false → continue behavior

Example 4: Collision Detection

Booleans are produced by comparisons.

if (dist < 40)

Explanation

The expression:

dist < 40

returns:

  • true if objects are close enough
  • false if they are too far apart

This controls collision logic.

Example 5: Object Existence Checks

Booleans help prevent errors.

if (fish)

Explanation

This checks whether:

  • the fish object exists
  • the object is valid
  • the game can safely interact with it

The condition evaluates to either true or false.

Example 6: Score Protection

Booleans are used in score validation.

if (this.score < 0)

Explanation

This comparison returns:

  • true if score is negative
  • false otherwise

The game uses this to prevent invalid values.

Example 7: Multiple Boolean Checks

My game combines booleans with nested logic.

if (dist < 40) {

  if (!this.gameEnv.elonHitCooldown) {

    this.gameEnv.gameScorer.deductPoints(10);

  }

}

Explanation

This uses multiple boolean conditions to:

  • detect collisions
  • check cooldown state
  • decide whether damage should happen

Booleans make complex game logic possible.

Why Booleans Help My Game

Booleans improved my project by:

  • controlling gameplay logic
  • managing enemy and player states
  • preventing repeated actions
  • supporting collision systems
  • enabling decision-making

Without booleans, the game could not properly react to gameplay events.
