Automatically zoom camera to a Tilemap in Godot 4.2

This video aims to solve the issue of setting up a scrollable camera which scales automatically to a given Tilemap. You will learn about the zoom function of the camera and also about camera limits.

With this, you no longer have to think about the camera or to struggle to zoom it to your play area. Just draw your Tilemap and the camera will zoom to fit the smallest side, similar to how it happens in games like Brotato and Kingdom: New Lands. This applies for both vertical and horizontal screens, so it could also be a useful feature for a moving camera in a phone video game.
