What Scripting Language Does GameMaker Use?


Larry Thompson

Scripting languages play a crucial role in game development, as they provide the means to create interactive and dynamic experiences. When it comes to GameMaker, one of the most popular game development engines, the primary scripting language used is GML (GameMaker Language).

What is GML?

GML is a powerful scripting language specifically designed for use with GameMaker. It offers a wide range of functions and features that allow developers to create complex games with ease. GML is similar in syntax to other scripting languages like JavaScript, making it relatively easy to learn for those familiar with programming concepts.

Why Use GML?

GameMaker provides a user-friendly interface and visual drag-and-drop functionality for beginners. However, as games become more complex, GML becomes essential due to its flexibility and control over game logic. GML allows developers to create custom behaviors, implement advanced algorithms, manipulate data structures, and optimize performance.

GML Features

1. Object-oriented: GML supports object-oriented programming (OOP) concepts such as inheritance and encapsulation. This enables developers to organize their code into reusable objects and create complex interactions between them.

2. Event-driven: In GameMaker, events are used to trigger actions or execute code when specific conditions are met. GML allows developers to define event handlers for various interactions such as collisions, keyboard input, mouse clicks, and more.

3. Extensive Function Library: GameMaker provides an extensive library of built-in functions that cover various aspects of game development. These functions range from basic operations like drawing shapes and playing sounds to more advanced tasks like pathfinding and physics simulations.

4. Data Structures: GML supports various data structures such as arrays, grids, stacks, queues, and maps. These data structures allow for efficient storage and retrieval of information, enabling developers to create complex systems and manage game data effectively.

GameMaker Studio 2

GameMaker Studio 2, the latest version of GameMaker, introduced a major update to the scripting capabilities. While GML remains the primary scripting language, it now also supports Drag and Drop functionality alongside traditional coding. This feature makes GameMaker even more accessible to beginners while still allowing experienced developers to leverage the power of GML.

GML Syntax Example:

To illustrate the simplicity and power of GML, here’s an example code snippet that creates a basic movement behavior for a player object:

// Create Event
speed = 5;

// Step Event
if (keyboard_check(vk_right))
    x += speed;
if (keyboard_check(vk_left))
    x -= speed;
if (keyboard_check(vk_up))
    y -= speed;
if (keyboard_check(vk_down))
    y += speed;

In this example, pressing the arrow keys moves the player object in the corresponding direction at a constant speed defined by the “speed” variable.


GML is a powerful scripting language that empowers developers to create engaging games using GameMaker. Its flexible syntax, extensive function library, support for OOP concepts, and event-driven architecture make it an ideal choice for both beginners and experienced programmers.

Whether you’re creating a simple prototype or a complex game project, mastering GML will undoubtedly enhance your game development skills. So dive in, explore its capabilities, and let your creativity shine!
