[SOLVED] How to load next level?

Solved this with this code - hopefully it is helpful to anybody!

 void OnTriggerEnter2D (Collider2D col) {
         if (col.CompareTag ("Player")) {
             //Load next scene
             print ("Collided!");
             SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
         }
     }

Hello! So I am trying to load the next level in my game. And I am wondering, how should I do this? After 5.3 the code for doing this is different. So far I have:

 void OnTriggerEnter (Collider other) {
         if (other.CompareTag ("NextL")) {
             
         }
     }

For some reason, the coding for this has gotten a lot more complicated.
