Movement and Animation doesn't work properly

Hi,

I have created an animation that works with the animator. On the animator there is a boolean, if the bool gets to true the animation “jump” will play.
My problem here is that the player only plays the jump animation but doesn’t move and I get this error message:

NullReferenceException: Object reference not set to an instance of an object

Here is the script that I use:

using UnityEngine;
using System.Collections;

public class PlayerControl3 : MonoBehaviour {

	private float perc = 1;
	
	private Vector3 startPos;
	private Vector3 endPos;

	public Animator anim;
	
	// Use this for initialization
	void Start () {

	}
	
	// Update is called once per frame
	void FixedUpdate () {
		if (Input.GetButtonDown ("up") || Input.GetButtonDown ("down") || Input.GetButtonDown ("left") || Input.GetButtonDown ("right"))
		{
			anim.SetBool("Jump",true);
		}
		
			else
			{
				anim.SetBool("Jump",false);
			}

		startPos = gameObject.transform.position;
		
		if(Input.GetButtonDown("right") && gameObject.transform.position == endPos)
		{
			endPos = new Vector3(transform.position.x + 1, transform.position.y, transform.position.z);
		}
		if(Input.GetButtonDown("left") && gameObject.transform.position == endPos)
		{
			endPos = new Vector3(transform.position.x - 1, transform.position.y, transform.position.z);
		}
		if(Input.GetButtonDown("up") && gameObject.transform.position == endPos)
		{
			endPos = new Vector3(transform.position.x, transform.position.y, transform.position.z + 1);
		}
		if(Input.GetButtonDown("down") && gameObject.transform.position == endPos)
		{
			endPos = new Vector3(transform.position.x , transform.position.y, transform.position.z - 1);
		}
		
		gameObject.transform.position = Vector3.Lerp (startPos, endPos, perc);
	}
}

If in the animation you change the position of the gameobject when you play the animation it will go to the position defined in the animation and override the movement. You might be able to fix this by adding a child gameobject with your cube then put your animator in the parent gameobject and then animate the cube. When you move the parent gameobject it should not mess up the animation because the position change will be inside the parent.
