This article introduces the first steps in creating a 2D platformer using Unity, aimed at those with a basic understanding of C# and the Unity interface. It guides through setting up the development environment, sourcing free game development assets, and initiating a Unity project. Key processes include setting up a development environment, creating a project in Unity Hub, downloading asset packs for game development, forming a Tile Palette for level design, and adding essential components like the Tilemap Collider 2D. This foundation sets the stage for more complex level development and introduces the upcoming focus on programming and physics for character movement control.
