Play animation for horizontal and vertical movement?

Question

Hey,

i did some research but did not find a clear answer, and when I had something I hard problems applying it to my script. What I want to do is play an animation when my character (first person) is moving forward and backward and a different one when he is moving left and right. So basically is there a way I can check for horizontal movement and vertical movement and then apply a specific animation to that movement.

If it helps here is my code for the movement of the character.

 using UnityEngine;
 using System.Collections;
 
 [RequireComponent (typeof(CharacterController))]
 public class FirstPersonController : MonoBehaviour {
     
     public float movementSpeed = 5.0f;
     public float mouseSensitivity = 2.0f;
     public float upDownRange = 60.0f;
     public float jumpSpeed = 3.0f;
     
     bool sprintCoolDown = false;
     float desiredUpDown = 90;    
     float verticalVelocity = 0;
     
     CharacterController characterController;
     
     // Use this for initialization
     void Start () {
         
         Screen.lockCursor = true;
         characterController = GetComponent<CharacterController>();
         
     }
     
     // Update is called once per frame
     void Update () {        
         // Rotation
         
         float rotLeftRight = Input.GetAxis("Mouse X") * mouseSensitivity;
         transform.Rotate(0 , rotLeftRight , 0);
         
         desiredUpDown -= Input.GetAxis("Mouse Y") * mouseSensitivity;
         desiredUpDown = Mathf.Clamp(desiredUpDown, -upDownRange , upDownRange);
         Camera.main.transform.localRotation = Quaternion.Euler (desiredUpDown , 0 , 0 );
         
         // Movement of Character
         
         if(Input.GetKey(KeyCode.LeftShift) && sprintCoolDown == false) {
             movementSpeed = 8.0f;
             StartCoroutine(sprintCD());
         }
         else {
             movementSpeed = 5.0f;    
         }
         float forwardSpeed = Input.GetAxis("Vertical") * movementSpeed;
         float sideSpeed = Input.GetAxis("Horizontal") * movementSpeed;
         
         verticalVelocity += Physics.gravity.y * Time.deltaTime;
         
         if( characterController.isGrounded && Input.GetButtonDown("Jump") ) {
             verticalVelocity = jumpSpeed;    
         }
         
         Vector3 speed = new Vector3 ( sideSpeed , verticalVelocity , forwardSpeed );
         
         speed = transform.rotation * speed;
                         
         characterController.Move( speed * Time.deltaTime );
             
     }
     IEnumerator sprintCD() {
             yield return new WaitForSeconds(6);
             sprintCoolDown = true;
             yield return new WaitForSeconds(4);
             sprintCoolDown = false;        
         }
 }

Any help is appreciated. Thanks a lot. Kind Regards Cribbel (Still a fair noob at unity but getting the hang of it)

By default, Unity has input controls set up for 'Horizontal' and 'Vertical'. You can see them by going into Edit>Project Settings>Input. There will be four fields: 'Positive Button', 'Negative Button', and the 'Alt Positive Button' and 'Alt Negative Button'.

So, vertical input would be W or S, or the up and down arrow keys. W and arrow up are positive, so they will return 1, while S and arrow down, will return -1. If none of those is pressed, it will return 0. The same is for the horizontal input.

Here is how you would play different animations according to which buttons are pressed:

 void Update(){
     //If the player is moving horizontally (left and right), and not diagonally or vertically
     //Remember: 1 is right (positive), and -1 is left (negative).
     if(Input.GetAxis("Horizontal") != 0 && Input.GetAxis("Vertical") == 0) {
         //Play your sideways animation
         animation.Play("Insert animation name here");
     }
     //If the player is moving vertically (forward and backward) or diagonally
     else {
         //Play your forward/backward animation
         animation.Play("Insert animation name here");
     }
 }

Play animation for horizontal and vertical movement?
