Game development is a thing that looks like a horrible monster at first, but after you know more about it, Game development will be a fun stuff that you can play around with. Here, we will talk about with one of the popular tool that called "game engine" for game development, Godot.

What is Game Engine?

A game engine is an application for developing games. To be able to develop games the game engine needs to be able to do at least a few things. For example: Display the game, simulate physics – which for example deals with what happens after 2 objects collide, play sound, save data, get input from player and support scripting. There are some criteria if a tool can be called game engine. Here's some of it:

  • Able to:
    • Display game
    • Simulate physics (gravity, collision detection …)
    • Play sound
    • Save data
    • Get input (keyboard, mouse …)
    • Support scripting

There are some of game engine, like:

    About Godot

    Godot is a game engine, in which you can make 2D and 3D games. It specializes in making 2D games, it’s one of the best 2D game engines out there. It’s not too far behind or it’s even as good as it’s competitors in making 3D games. The quality and speed of development of this relatively new game engine could be partially because it is open source, that mean this game engine is developed not by a person or company, but by the community. You also can contributing to build or improvise this engine by do some pull requests on their GitHub repository, here.

    Godot is newbie-friendly, that mean you can use it even without years of coding experience. Since it use a Python-like language that called GDScript, it's easy to learn it's syntax. Godot also a good choice for an early step into the game development world.

    Where I Can Install Godot?

    You can install Godot at their official website, here.

    Basic Concept of Godot

    Godot using a system that called "node" for every game object of it. There are such types of nodes, but we can categorize some of it to:

    • 2D nodes. Types of nodes that used in 2D games.
    • 3D nodes. Types of nodes that used in 3D games.
    • Control nodes. Types of nodes that used for building UIs.
    • Utilities nodes. Types of nodes that used for doing some utilities stuffs, like sending a HTTP request.

    Godot also using a scene system, that contains many nodes with one of it as the parent node named "root".
