Secret Areas with Tilemaps - Godot 4 Tutorial

When I first played New Super Mario Bros Wii, I was fascinated by how the game implemented secret areas in game, where the player could collide with a fake wall only for it to vanish and show what's behind it.

Since then, I always wanted to make a game with secrets like that and today I finished making a video about how I've done it! The way I've done is pretty simple, but also makes sure that the secret areas are easy to implement while level designing.

Secrets are fun, more games should have them!
