2D and 3D games

Learn the differences between 2D and 3D games and their approaches.

2D Games

2D games are created in a two-dimensional world. Object positions in this world are generally represented using horizontal and vertical axes. Characters and objects are often represented by two-dimensional images called sprites.

   |   ● Character

   +----------→ X

Platform and puzzle games can be developed using a 2D approach.

3D Games

3D games are created in a three-dimensional world. Objects have three position axes: horizontal, vertical, and depth. Characters, buildings, and environment objects are often built using three-dimensional geometric models called meshes.

With a 3D approach, objects can be viewed from different angles and create a sense of depth.

Exercise Print the Type of a 2D Object

To identify a character's visual type in a 2D game, assign the value sprite to the objectType variable and print it.

Show example solution

// 2D karakterin görsel türü
const objectType = "sprite";
console.log(objectType);

Test yourself

Which element is commonly used to represent a character's visual appearance in a 2D game?
- Three-dimensional camera
- Audio file
- Sprite
- Mesh
Show answer

Sprite — A sprite is a two-dimensional image that represents characters and other visual objects in 2D games.

Identify the Three-Dimensional Model

const objectType = "____";
console.log(objectType);

Show answer

const objectType = "mesh";
console.log(objectType);
