Detecting movement (unity 2d)

How do i make so my script detects when my player is moving? Please help me! I have tried everything...

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Knight : MonoBehaviour
5. {
6.  
7.     void DetectPlayerMoving()
8.     {
9.         //insert code here
10.     }
11.  

 

Erm... is the Knight script attached to a GameObject with a rigidbody? If so all you need to do is get the rigidbody with GetComponent<Rigidbody2D>() in Start and store it in a global variable, then check in FixedUpdate if the magnitude of it's velocity is larger than some threshold.

 

If it only moves ones then You could have a moving variable that you enable in your movement code. Then you could set it to false in update if it isn't already code:

Code (CSharp):

1.  
2. bool moving = false;
3.  
4. // Add this to movement code:
5. moving = true
6.  
7. void Update() {
8.         if(moving == true){
9.                 moving = false;
10.         }
11. }

Hope this helps!
