Create False Floor Game Mechanic in Unity

This video will show you how to create a false floor prefab and game mechanic for Unity. False floors are used in several different video games but most commonly they can be found in platformers. A false floor is a regular floating platform that the player can not normally tell is false but as soon as the player steps onto the platform, it then falls out from under them. We will create a system in this video so that there should be a true path for the player to find their way to the other side. This path will be random and different every game.
