Right now in the club, we are working on a simple first game project, following the official Godot documentation. https://docs.godotengine.org/en/stable/getting_started/first_2d_game/index.html?authuser=0
This is a step-by-step tutorial to make a simple dodging game to get used to coding and game art in 2D. There's lots of resources online that make learning a new skill really easy, like tutorials like these, youtube videos, or example projects like those that can be found on this website made by the gamedev club itself.
You will learn to:
Create a complete 2D game with the Godot editor.
Structure a simple game project.
Move the player character and change its sprite.
Spawn random enemies.
Count the score.
There is also a Your First 3D Game tutorial in Godot that you can follow, to learn to make a 3D project from scratch, with a very detailed tutorial. https://docs.godotengine.org/en/stable/getting_started/first_3d_game/index.html
