How to Make a 2D Platformer in Godot (Beginner Tutorial)

Summary

This tutorial walks viewers through building a basic 2D platformer using the Godot game engine. It begins by creating a player character with animated sprites, setting up idle, running, jumping, and dying animations, and implementing movement using built-in physics like gravity, velocity, and collision. The video explains how to customize input controls, adjust jump and gravity physics for better gameplay feel, and flip the sprite to face the correct direction. It also demonstrates adding sound effects for actions such as jumping. Finally, the tutorial introduces level creation using a tilemap, adds collision to tiles, sets up a background, and organizes scenes to form a playable platformer level.

Takeaways

• 😀 The video introduces how to make a simple platformer game in Godot Engine, covering player creation, animations, enemies, and levels.
• 😀 Godot's scene system is based on nodes, where everything in the game, including the player, is made up of various nodes like `CharacterBody2D` for the player and `AnimatedSprite2D` for animations.
• 😀 The player’s animations, including idle, jump, run, and hit, are loaded from sprite sheets. These animations are configured using Godot's `AnimatedSprite2D` node, with frame rates adjusted for smooth gameplay.
• 😀 The script for the player character is created by extending `CharacterBody2D`, which automatically provides built-in physics like gravity and movement, reducing the need for custom code.
• 😀 Player movement is controlled using the arrow keys or custom keys (A/D for left/right, spacebar for jump). The script handles jumping, gravity, and horizontal movement.
• 😀 The player's animation switches between idle, running, and jumping states based on movement and air status, with additional code to handle direction-flipping for moving left and right.
• 😀 Sound effects, such as a jump sound, are added to the player using an `AudioStreamPlayer2D` node, which is triggered during key presses.
• 😀 A level is created using a `TileMap` node, with tiles drawn from a predefined tile set. The tiles' physics and collisions are defined to allow player interaction with the environment.
• 😀 The game’s background is set up using a `TextureRect` node, which can be stretched or tiled to fit the game window. The background image is set to 'nearest' filter mode to avoid blurriness.
• 😀 The player is added to the level by instantiating the player scene as a child of the level scene, ensuring the player is correctly placed within the level for gameplay.
• 😀 Basic collision detection is set up both for the player (using `CollisionShape2D`) and the tiles (with collision shapes automatically assigned to tiles in the `TileSet`), ensuring the player cannot fall through the ground.

Q & A

What is the main tool used to create the platformer game in the video?

The platformer game is created using GDAU (Godot), a popular game engine for both 2D and 3D game development.

How are the player character’s animations set up in GDAU?

Player animations are set up using the `AnimatedSprite2D` node. Various sprite sheets are added for different animations like idle, jump, run, and hit. The sprite frames are defined in the `sprite frames` property, and the speed of the animations is adjusted accordingly.

How does the player character flip when moving in the opposite direction?

The player character is flipped horizontally by setting the `flip_h` property of the `AnimatedSprite2D` node to true when moving left, and false when moving right. This allows the player to face the correct direction based on their movement.

What issue was encountered with the player’s initial animation, and how was it fixed?

Initially, the player remained stuck in the idle animation. The solution was to add an `autoplay onload` option for the `AnimatedSprite2D` node, so that it automatically starts the idle animation when the scene is loaded.

What is the purpose of the collision shape in both the player and platform nodes?

Collision shapes are used to define the physical boundaries of objects for interaction. The player node has a `CollisionShape2D` to prevent it from passing through the ground, while the platform node also has a `CollisionShape2D` to ensure the player can stand on it.

Why was a custom script added to the player node?

A custom script was added to control the player's movement and jumping. The script handles player physics, including gravity, movement based on input keys (A, D for left/right, space for jumping), and defines how the player interacts with the game environment.

How is gravity and jump velocity adjusted in the game?

Gravity is set through the project settings under `Physics > 2D > Gravity`, with the default value changed to 2500 to make jumps feel snappier. The jump velocity is adjusted to -850 to ensure the player’s jump height is suitable for the game’s physics.

What steps were taken to implement sound effects for the player’s actions?

Sound effects are added by creating an `AudioStreamPlayer2D` node for the player. The sound file (e.g., for jumping) is dragged into the node's `stream` property, and the sound is triggered when the jump action is initiated in the script.

How does the level in the game get created?

The level is created using a `TileMap` node. The tileset is loaded from an image atlas, and individual tiles are drawn on the map using different drawing tools like the line, rectangle, and paint bucket tools. The scale of the tiles is increased to match the game’s resolution.

What is the significance of the ‘nearest’ texture filter setting?

The 'nearest' texture filter setting is used to improve the quality of pixel art by avoiding the blurry effect that occurs when textures are stretched. This setting ensures that pixel art looks sharp and clear, rather than pixelated.
