Boolean Expressions in My Game

What Are Boolean Expressions?

Boolean expressions are statements that evaluate to either:

true

or

false

They are used to make decisions in programming.

Games use boolean expressions for:

  • collision detection
  • enemy behavior
  • score conditions
  • game states
  • input handling

My game uses boolean expressions constantly in gameplay logic.

Why Boolean Expressions Are Important

Without boolean expressions, the game could not:

  • make decisions
  • detect collisions
  • control AI behavior
  • manage conditions
  • respond to player actions

Boolean expressions are the foundation of game logic.

Example 1: Collision Check

My game uses boolean expressions to detect collisions.

if (dist < 40)

Explanation

This expression evaluates to:

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

It controls when:

  • damage happens
  • score changes
  • interactions trigger

Example 2: Equality Check

The game checks exact matches using boolean expressions.

obj.constructor.name === "Player"

Explanation

This evaluates to:

  • true if the object is a Player
  • false otherwise

It is used for:

  • filtering objects
  • enemy targeting
  • game logic decisions

Example 3: String Boolean Expression

My game checks if text contains certain values.

obj.spriteData?.id?.includes("EnemyElon")

Explanation

This returns:

  • true if the string contains “EnemyElon”
  • false if it does not

Used for:

  • enemy detection
  • filtering arrays
  • gameplay logic

Example 4: Boolean Expressions in Conditions

Boolean expressions are used inside if statements.

if (!this.gameEnv.elonHitCooldown)

Explanation

This expression:

  • evaluates cooldown state
  • returns true or false
  • controls whether damage is applied

The ! operator reverses the boolean value.

Example 5: Range Comparison

My game uses comparison expressions for AI movement.

if (dist < minDist)

Explanation

This evaluates:

  • whether a player is closer than previous target
  • updates nearest enemy target

It helps control enemy AI behavior.

Example 6: Object Existence Check

Boolean expressions prevent errors.

if (fish)

Explanation

This evaluates:

  • true if the object exists
  • false if it is undefined or null

It ensures safe interactions in the game.

Example 7: Score Validation

The game uses boolean expressions for score rules.

if (this.score < 0)

Explanation

This evaluates:

  • true if score is negative
  • false otherwise

Used to prevent invalid score values.

Example 8: Combined Boolean Logic

My game uses multiple boolean expressions together.

if (dist < 40 && !this.gameEnv.elonHitCooldown)

Explanation

This evaluates to true only if:

  • player is close enough
  • cooldown is not active

This controls damage logic efficiently.

Why Boolean Expressions Help My Game

Boolean expressions improved my project by:

  • enabling decision-making
  • controlling collisions and interactions
  • managing enemy AI behavior
  • preventing errors
  • supporting gameplay logic

Without boolean expressions, the game would not be interactive or functional.
