You can control the behavior of your characters in Unity using JavaScript(JS) or C#. Though JS is an easier language and a lot of people know it, from my initial research I concluded that C# trumps JS when it comes to scripting on Unity. I added a custom controller to control my character in Unity and added a C# script to define the behavior of the character when keys on keyboard are pressed.

I achieved this by following two tutorials:

• https://community.mixamo.com/hc/en-us/articles/204581427-Unity-Mecanim-Advanced-Animation

I followed only half of this tutorial to learn how to create custom controllers, assign it to a character, and add states in Mecanim

• https://teamtreehouse.com/library/how-to-make-a-video-game (I would recommend this tutorial)

Used it to know more about C# (Note: this was my first encounter with C#).

Following are the steps I took in my project:

• Added a custom controller to my player using Animator component on the player
• Added a C# script to the player
• Added a state to the player controller; other than 'Entry' and added to animations to the state using BlenTree; Idle and Walking
• Added the following code to the C# script that we assigned to the player earlier. There was a lot of trial and error to make the code work:

using UnityEngine;
using System.Collections;

public class ShivaControllerScript : MonoBehaviour {

private Animator myAnimator;
private float moveHorizontal;
private float moveVertical;
private Vector3 movement;
private float turningSpeed = 20f;
private Rigidbody playerRigidbody;

// Use this for initialization
void Start () {
myAnimator = GetComponent ();
playerRigidbody = GetComponent ();
//playerRigidbody = GetComponent ();

}

// Update is called once per frame
void Update () {

moveHorizontal = Input.GetAxisRaw ("Horizontal");
moveVertical = Input.GetAxisRaw ("Vertical");

movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

//myAnimator.SetFloat ("Speed", Input.GetAxis("Vertical"));

}

void FixedUpdate () {

if (movement != Vector3.zero) {

Quaternion targetRotation = Quaternion.LookRotation(movement, Vector3.up);
Quaternion newRotation = Quaternion.Lerp (playerRigidbody.rotation, targetRotation, turningSpeed * Time.deltaTime);
playerRigidbody.MoveRotation(newRotation);

myAnimator.SetFloat ("Speed", 60f);
//myAnimator.SetFloat ("Speed", Input.GetAxisRaw("Vertical"));

} else {

myAnimator.SetFloat ("Speed", 0f);
//myAnimator.SetFloat ("Speed", Input.GetAxisRaw("Vertical"));
}

}

}
