Play animation for horizontal and vertical movement?

Questions & Answers
1

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

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");
	}
}
