Add First Person

Adding the first person was simple but took a long time to download, due to many people downloading the asset at the same time. It was a bit confusing but after a while it was easy, but my character will help the player interact with things and learn things.With first person, the character will not be seen only he can see, but with third person, the character will be seen more exploration around the scene.And with first person, its easy to use and more time to explore the scene than third person.
