Construct Event Sheet Example

// Event Sheet Example (pseudo-code)

// On start of layout
System -> Set variable score to 0

// On player collision with coin
Player.OnCollision(Coin) -> {
    Destroy(Coin);
    Add 10 to score;
    TextScore.SetText("Score: " + score);
}

// On player collision with enemy
Player.OnCollision(Enemy) -> {
    System.RestartLayout();
}

Example of Construct-style event scripting represented in pseudo-code/JS-like syntax for clarity.

Construct Jump and Collect Coins

// On start of layout
System -> Set variable score to 0

// On player press space
Keyboard.OnKeyDown(Space) -> {
    Player.SetAnimation("Jump");
}

// On collision with coin
Player.OnCollision(Coin) -> {
    Destroy(Coin);
    Add 5 to score;
    TextScore.SetText("Score: " + score);
}

Player jumps and collects coins.

Construct Enemy Patrol Example

// On start of layout
System -> Set variable direction to 1

// On every tick
Enemy -> {
    Enemy.X += 2 * direction;
    If Enemy.X > 400 -> Set direction to -1;
    If Enemy.X < 100 -> Set direction to 1;
}

Enemy patrols back and forth.

Construct Timer Countdown

// On start of layout
System -> Set variable timeLeft to 60

// Every second
System.OnEverySecond -> {
    timeLeft -= 1;
    TextTimer.SetText("Time: " + timeLeft);
    If timeLeft <= 0 -> System.RestartLayout();
}

Countdown timer event sheet.

Let’s Try →

Construct Player Shooting

// On press key
Keyboard.OnKeyDown(F) -> {
    CreateObject(Projectile, Player.X, Player.Y);
    Projectile.SetAnimation("Fly");
}

// On projectile collision
Projectile.OnCollision(Enemy) -> {
    Destroy(Projectile);
    Destroy(Enemy);
}

Player shoots projectiles when pressing a key.

Let’s Try →

Construct Collectibles with Random Spawn

// On start of layout
System -> Set variable score to 0

// Every 3 seconds
System.OnEvery(3 seconds) -> {
    CreateObject(Coin, random(50, 450), random(50, 350));
}

// On player collision with coin
Player.OnCollision(Coin) -> {
    Destroy(Coin);
    Add 10 to score;
    TextScore.SetText("Score: " + score);
}

Randomly spawn collectibles over time.

Let’s Try →

Construct Level Complete Event

// On start of layout
System -> Set variable coinsCollected to 0

// On player collision with coin
Player.OnCollision(Coin) -> {
    Destroy(Coin);
    Add 1 to coinsCollected;
    If coinsCollected >= 10 -> System.GoToLayout("NextLevel");
}

Check win condition and go to next level.

Let’s Try →

Construct Enemy Damage Player

// On start of layout
System -> Set variable health to 100

// On player collision with enemy
Player.OnCollision(Enemy) -> {
    Subtract 10 from health;
    If health <= 0 -> System.RestartLayout();
    TextHealth.SetText("Health: " + health);
}

Player loses health on collision with enemy.

Let’s Try →

Construct Moving Platform

// On start of layout
System -> Set variable direction to 1

// Every tick
Platform -> {
    Platform.X += 2 * direction;
    If Platform.X > 400 -> Set direction to -1;
    If Platform.X < 100 -> Set direction to 1;
}

Platform moves back and forth horizontally.

Frequently Asked Questions about Construct

What is Construct?

What are the primary use cases for Construct?

2D game development without coding. Educational games. Indie mobile and web games. Rapid prototypes and game jams. Cross-platform HTML5 deployment

What are the strengths of Construct?

No coding required, beginner-friendly. Rapid iteration with visual editor. Cross-platform export options. Active community and tutorials. Extensible with JavaScript and plugins

What are the limitations of Construct?

Primarily 2D, limited 3D support. Performance dependent on HTML5/Canvas/WebGL. Less suitable for AAA or complex 3D games. Event sheets can become complex for large projects. Advanced users may find JavaScript integration limited compared to full engines

How can I practice Construct typing speed?
