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.

Create Bounce Bumper Game Mechanic in Unity

This lesson will show you how to create a bounce bumper prefab and game mechanic in Unity. Bounce bumpers are used in many different video games. They are most commonly found in platformers and are used to bounce the player of a ledge. They are also found in many pinball type games.

To create a bounce prefab you will need to begin with a capsule object that you can replace in the future. this capsule needs to have a collider after which you can add a new script to this object. Inside the script, you will want to you the oncollisionenter function to detect the interaction between the player and the bumper. Inside this function, you will want to add an explosion force to your player at the point of the collision.

Crushing Block Game Mechanic in Unity – Thwomp or Hydraulic Press

Group Unity Project: https://www.infogamerhub.com/collaborative-unity-project-1/

In this lesson, I will show you how to create a Crushing Block prefab and game mechanic in Unity similar to the Thwomps from Mario or a Hydraulic Press. We created this game mechanic for our group Unity project and this prefab is included in our level builder unity package.

To create this crushing block prefab we will first design the prefab in Unity. We can then animate this object so that it has a crush, reset, and wait time animation. We will then create a script for this object that will allow you to increase the wait time animation time in the inspector. We will then create another script that will be for the objects that get crushed.
