Unity 2D Trigger Detection is not working.

Hello All,

I am currently trying to get a 2d sprite character moving around on screen and able to interact with the game world. I intend to do this with triggers. The character is a 2d sprite with a sprite renderer and animator setup. It also has a 2d box collider attached and is currently tagged player. I also have a rigidbody assigned to it.

To test out the ability of interacting with the world, I setup a simple 2d box collider with the trigger checkbox marked and called the game object the 'Interaction area'. The idea is that my fully functional character walks into the area and a print statement prints to the console. this is the code that does it (and is attached to the game object i call floor trigger, and also assigned a rigidbody to it):

 using UnityEngine;
 using System.Collections;
 
 public class Floor_Trigger : MonoBehaviour {
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void OnTriggerEnter(Collider other){
         Debug.Log("Something has entered this zone.");    
     } 
     void OnTriggerExit(Collider other){
         Debug.Log("Something has entered this zone.");    
     } 
     void OnTriggerStay(Collider other){
         Debug.Log("Something has entered this zone.");    
     } 
 
     void OnCollisionEnter(Collision collision){
         Debug.Log("something has hit me");
     } 
 }

I put in various trigger methods in case any one of them were fired. But so far, absolutely zero luck. And I have looked around on the internet and google (please do not post that I should search google), and so far the methods I have tried out haven't gotten this to work. Is there anything that I am missing?
