In this video, We talk more about our marble game group Unity project. I explain that I will be updating this Unity project on a weekly basis. I hope that you will join this group project and help us create levels in Unity for this game.

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

We will also show you how to create a ball roll mechanic in Unity. We are using a ball roll mechanic for this group Unity project. Ball rolling is a very popular game mechanic found in many video games. If you haven’t learned how to make a ball roll in Unity then this is the video for you as I show you how to create a basic but effective ball prefab that you can use in any of your unity projects.
