Introduction In this tutorial, we are going to implement a “grid-based movement” system for a 2D game in Godot. It’s not overly complex. Some of you might be wondering, what exactly is grid-based movement? Grid-based movement is when objects, such as characters, move one grid (one tile) at a time on a game screen that is divided into evenly spaced grid lines. To give some examples, think of older games like the Fire Emblem series, Tactics Ogre, or various simulation games. Even RPGs like Final Fantasy and Dragon Quest during their 2D eras employed grid-based movement when it came to character movement on maps. Puzzle games like Tetris often use grid-based movement for the blocks or pieces as well. As you can see, grid-based movement is widely used across many genres of games, making it a highly versatile feature. Environment This tutorial was created under the following environment: Godot version: 4.3 Computer OS: macOS 14.6.1 By the way, the project I made can be found in this GitHub repository .

Introduction With Godot 4.3, the previously used TileMap class has been deprecated (meaning it won’t be updated anymore), and a new TileMapLayer class has been added in its place. So, I’m going to actually create a tilemap using TileMapLayer! My environment at the time of writing Godot version: 4.3 Computer model: MacBook Air M1, 2020 OS: macOS 14.6.1 Setting the Screen Size I’ll be using 16x16 px tile images this time, so I’ll make the Viewport small enough to fit the tiles neatly. After creating a new project, I went to Project Settings > General tab > Window and set the following: Size: Viewport Width: 256 Viewport Height: 160 Window Width Override: 1024 (4 times) Window Height Override: 640 (4 times) *Window Width Override and Window Height Override can be set after enabling Advanced Settings in the top right of the settings panel. Then I scrolled down a bit in the settings panel and set the stretch mode to viewport so that the game graphics scale to fit the window size. I left the aspect ratio as is. Stretch: Mode: viewport Aspect: keep (default) Scale: 1 (default) Scale Mode: fractional (default) Importing Assets for Tiles I downloaded the 1-Bit Pack from KENNEY ....

In the previous article 🤖 Adding Game Center Plugin to Your Project , I explained how to add the Game Center plugin from the official Godot iOS plugins to your project. In this article, I’ll guide you on implementing the functionalities of Apple’s Game Center using the added plugin. If you’re wondering what Game Center is all about, I briefly explained it in the beginning of the previous article, so you might want to check that out first. Broadly, I’ll explain in two main sections: Setting Up Game Center in App Store Connect Implementing Game Center in GDScript By the way, the basic usage of plugins is documented in Godot Docs / iOS plugins / iOS plugins , so it would be reasonable to start there. Also, you can find the code for the Game Center plugin on GitHub at Godot iOS GameCenter plugin . If you want to delve into the details, you can check it out.

Introduction In this article, I’ll show you how to add the official Godot plugin for integrating with Apple’s Game Center to your project. First off, what is Game Center? For those unfamiliar, it’s a feature available on iOS devices like iPhones and iPads. By signing in with an Apple ID, Game Center records achievements and allows players to compete on leaderboards in supported games. Developers can set achievements, define their completion criteria, and decide what to compete for on the leaderboards. Using the Game Center plugin in Godot, you can easily integrate these features into your games, which is pretty awesome. By the way, you can find the official documentation and source code at the Godot iOS plugins repository , so take a look there first. If there’s anything you don’t quite understand, you can always come back to this article.

This article explains how to switch between and play multiple sound resources (music and sound effect files) with a single “AudioStreamPlayer” node. Basically, only one sound resource can be set per “AudioStreamPlayer” node. In other words, you must add “AudioStreamPlayer” nodes in the scene tree for each sound resource. You may feel useless in a situation where there are multiple nodes in the scene tree with the same settings except for the sound resource (as shown in the screenshot below), and you may also feel a little uncomfortable with the lack of visibility in the scene dock. So, if you have multiple sound resources that are never played simultaneously (e.g., multiple sound effects for different types of character attacks, multiple sound effects for different types of buttons on the UI, etc.), add only the minimum necessary “AudioStreamPlayer” node for each use to your scene. If you code a program that switches sound resources according to the situation, there will be no waste and the scene dock will look cleaner. In this tutorial, we will prepare only one “AudioStreamPlayer” node and...

This article describes an implementation of an animated state machine for a 2D game. A state machine controls the transition of an object from one state to another. There are several restrictions on state transitions, such as when an object can only transition from one state to a limited number of states, or when an object can only transition to the next state after the current animation ends. For example, “idle” and “run” can transition immediately in both directions, but “idle” to “attack” can transition immediately, but “attack” to “run” cannot, and “attack” to “idle” can transition only after the “attack” animation ends. The “attack” to “idle” transition occurs only after the “attack” animation is over. If all of these controls were coded in script, the code would tend to be rather long and complex. On the other hand, Godot’s “AnimationTree” node can be used to reduce the amount of script code and improve readability. In this article, we will show you how to implement a state machine using the “AnimationTree” node. Environment Godot version: 3.5.1 Computer OS: macOS 12.6...

This article introduces a method for implementing simple hit detection for melee attacks in 2D games. This is a commonly used method where the object to attack (e.g., player character) has a collision shape (called “Hit Box”) that is only active during the attack, and the object to be attacked (e.g., enemy character, destructible barrels, crates, grass, etc.) has a collision shape (called “Hurt Box). The hit judgment of the attack can be implemented by enabling/disabling the Hit Box and Hurt Box, and changing their size and position in accordance with the animation of the attack. This is relatively easy to implement, so let’s get started. Environment Godot version: 3.5.1 Computer OS version: macOS 11.6.5 Basic Articles You may also find the following articles useful.

This tutorial introduces Path Finding in 2D games. Path finding is a function that determines the shortest possible path from an object to its destination, for example, when moving an object to a certain destination. Up to Godot 3.4, the Navigation node was used to implement path finding. This was not particularly inconvenient, but the methodology for game development using it was limited and inapplicable in some areas. This time, I would like to introduce an implementation method using Navigation Server, which was added to Godot 3.5. This is a backport from Godot 4, which is currently under active development. This article is intended for users of Godot 3.5 or later. Users of Godot version 3.4 or earlier should take note. The final project file for this tutorial is available at GitHub repository .

In this article, I will explain how to implement an effect, “screen shake”, in 2D games. It is not an absolutely necessary element of a game, but if used well, it can make the player’s game experience more interactive and directly affect the user experience. For example, there are many situations where it could be used, such as when a player fires a gun, takes damage from enemies, or falls from a high place. By the way, this kind of element that is not necessary but makes the game more interesting by adding it is called “game juice” in English. I have one more vocabulary in English, and I am a little wiser now. There are already many resources on the Web that explain how to implement screen shake, and of course there are methods other than those introduced here. This time, we refer to the following video and article in particular, so please check them as well for a deeper understanding.

In this tutorial, we will create an advanced match-3 puzzle game, a type of puzzle game in which one piece is moved freely on the board for a certain period of time to erase three or more pieces of the same color in a row. This is easy to understand if you imagine a puzzle game like “Puzzle & Dragons” (a.k.a. “Puzzle Dora”), which has gained popularity as a mobile game. However, the tutorial would be too large if it included all game elements such as decks, gacha, and battles with enemy characters, so we will focus on the puzzle part of the tutorial this time. For more information on how to create an standard match-3 puzzle game like “Candy Crush” or a puzzle game like “LINE Tsum Tsum”, please refer to the following tutorial.

In this tutorial, we will create a match 3 puzzle game. Match 3 is a puzzle game in which players move multiple colorful pieces evenly arranged along a grid on the board to eliminate three or more pieces of the same color in a row. This genre is particularly popular among mobile game players because it is easy to operate and enjoyable. Candy Crush, Toon Blast, and Royal Match are just a few examples of popular games. Puzzle & Dragons and LINE Tsum Tsum are also based on Match 3, although the controls are slightly different. In this tutorial, we will create a puzzle like Candy Crush, in which the pieces are moved only one square at a time to match colors.

In this time, we will create a bullet hell aka barrage for a barrage shooting game. The bullet hell is a large number of bullets (or similar long-range attacks) like a curtain. A “bullet hell shooter” is a game in which the player shoots at and defeats enemy characters while dodging and weaving through the gaps between the bullets. Some games specialize in simply dodging the bullets. Many games are based on the motif of spaceships and fighter planes that fit the image (in this tutorial, a ground battle between a wizard and a monster though). In this tutorial, we will focus only on creating a bullet hell. Also, while bullet hell come in various shapes and sizes, we will focus on rotating-type bullet hell.

Handgun Shotgun Machine gun Laser Gun Environment This tutorial was created in the following environment ・Godot version: 3.4.2 ・Computer OS version: macOS 11.6.5 Since this tutorial will focus on gun creation, the following has been prepared in advance. 1. Game world A scene called “World.tscn” was prepared, and the appearance was simply created by adding a “TileMap” node. In addition to the “TileMap” node, a “Player” node and several “Obstacle” nodes were added. For these, we created individual scenes and added the instances. 2. Player Character Created as “Player.tscn” scene. The root node is the “KinematicBody2D” class, and the “Sprite” and the “CollisionShape2D” were added as child nodes. The texture of the “Sprite” node is a hitman with a gun. A node named “Muzzle” of the “Position2D” class was placed at the tip of the image of the gun held by the hitman....
