I'm very new I just need some help

So I'm working on something small to get myself started but my question is how do I load the next level, do I teleport the player and camera? I'm just lost and stuck and I don't quite understand how loading next level works.

Hi,

You can change scene by using SceneManager.LoadScene(); - /!\ you have to make sure that the scene you’re trying to load is builded inside your game. (Build settings > Scenes in Build)
Depends on what you want to do : if you have 2 areas of gameplay inside the same scene, you could just teleport the player of course.
If you’re new to Unity, I suggest you to do the Junior Programmer course, that you can find on learn.unity.com.
This course will introduce you to scene flow and data : Junior Programmer: Manage scene flow and data - Unity Learn
