Creating a pixel platformer is a fantastic way to dive into game development, and Godot 4 makes the process accessible and efficient. This guide will walk you through building a complete pixel platformer, from setting up the project to creating a character that can jump, run, and interact with a pixel-perfect environment.

Setting Up Your Project

First, you'll need to download and install Godot 4 from the official website. Once installed, open Godot and create a new project. Name it something like "PixelPlatformer" and choose a location on your computer to save it.

Importing Assets

For a pixel platformer, you’ll need some sprites for your character, tiles for the platforms, and perhaps some background elements. You can create your own or find free assets online. Import these assets into your Godot project by dragging them into the res:// directory in the FileSystem panel.

Setting Up the Scene

In Godot, scenes are the building blocks of your game. Start by creating a new scene for the main game. This scene will contain your player character, platforms, and other game elements.

  1. Create a 2D Scene: Click on the "Scene" menu, then "New Scene". Choose "2D Scene" as the root node.
  2. Add a TileMap: This will be used to create the platforms. Click the "+" button to add a new node and select "TileMap".
  3. Configure the TileMap: In the inspector, set the cell size to match the size of your tiles (e.g., 16x16 if your tiles are 16x16 pixels).

Creating the Player Character

Now, let's create the player character. Start by adding a new scene for the player.

  1. Create a Player Scene: Create a new scene with a "KinematicBody2D" as the root node. Name it "Player".
  2. Add a Sprite: Add a "Sprite" node as a child of the "KinematicBody2D". Assign your player sprite texture to this node.
  3. Add a CollisionShape2D: This will define the player's collision boundaries. Add a "CollisionShape2D" node and assign a shape that fits your player sprite (e.g., a rectangle).

Getting Started with Godot

Coding the Player Movement

Next, we’ll add a script to handle the player’s movement. Right-click the "Player" node and select "Attach Script". Name it "Player.gd" and save it. Open the script and start coding the basic movement.

gdscript
extends KinematicBody2D const SPEED = 200 const GRAVITY = 500 const JUMP_FORCE = -300 var velocity = Vector2.ZERO func _physics_process(delta): velocity.y += GRAVITY * delta if Input.is_action_pressed("ui_right"): velocity.x = SPEED elif Input.is_action_pressed("ui_left"): velocity.x = -SPEED else: velocity.x = 0 if is_on_floor() and Input.is_action_just_pressed("ui_up"): velocity.y = JUMP_FORCE velocity = move_and_slide(velocity, Vector2.UP)

This script handles basic movement: running left and right with arrow keys and jumping with the up arrow key. The move_and_slide method makes it easy to handle collisions and sliding.

Creating the TileMap

Next, set up the TileMap to create the platforms.

  1. Create a TileSet: Select the TileMap node and click on the "TileSet" property in the inspector. Click "New TileSet", then "Open Editor".
  2. Add Tiles: Click the "+" button and select your tile texture. Define the tiles by dragging over the texture in the editor.
  3. Painting the Map: Use the TileMap node to paint the platforms in the main scene.

Setting Up the Camera

To follow the player, add a Camera2D node as a child of the Player node.

  1. Add a Camera2D: Right-click the Player node, add a Camera2D, and set it to current.
  2. Adjust Camera Settings: You may need to tweak the camera settings to ensure it follows the player smoothly.

Adding Backgrounds and Parallax

To give your game more depth, add a parallax background.

  1. Create a ParallaxBackground: Add a ParallaxBackground node to the main scene.
  2. Add ParallaxLayer: Add a ParallaxLayer as a child of the ParallaxBackground. Add a Sprite to the ParallaxLayer and assign your background texture.

Enhancing the Gameplay

You can enhance the game by adding various elements such as enemies, collectibles, and sound effects.

Adding Enemies

  1. Create Enemy Scene: Create a new scene with a KinematicBody2D, Sprite, and CollisionShape2D.
  2. Script Enemy Behavior: Attach a script to handle enemy movement and interactions.
gdscript
extends KinematicBody2D const SPEED = 100 var direction = Vector2.LEFT func _physics_process(delta): velocity = direction * SPEED velocity = move_and_slide(velocity) if is_on_wall(): direction = -direction

Adding Collectibles

  1. Create Collectible Scene: Create a new scene with an Area2D, Sprite, and CollisionShape2D.
  2. Script Collectible Behavior: Attach a script to handle collecting items.
gdscript
extends Area2D signal collected func _ready(): connect("body_entered", self, "_on_body_entered") func _on_body_entered(body): if body.is_in_group("player"): emit_signal("collected") queue_free()

In your player script, you can connect to the collected signal to increase the score or trigger other effects.

Adding Sound Effects

Import sound files and add an AudioStreamPlayer node to your scenes. Play sounds when specific actions occur, like jumping or collecting an item.

gdscript
$AudioStreamPlayer.play()

Polishing Your Game

  1. Add a Main Menu: Create a main menu scene with buttons to start the game, view credits, or quit.
  2. Create Levels: Design multiple levels and add a mechanism to transition between them.
  3. Add a UI: Display the player’s score, lives, and other stats using a CanvasLayer and various UI nodes.

Exporting Your Game

Once your game is complete, export it so others can play.

  1. Configure Export Settings: Go to Project -> Export and set up export templates for your target platforms (e.g., Windows, Mac, Linux).
  2. Export: Click "Export" to generate the game executable.

Conclusion

Building a pixel platformer in Godot 4 involves creating scenes, scripting character movement, designing levels, and adding polish to enhance the player experience. By following this guide, you can develop a fun and engaging game while learning the ins and outs of Godot 4. Happy game developing!
