Hey guys i have been working on a character controller and some cross platform UI and i am getting the error “Object Reference Not Set To an instance of an object” I am not sure why im getting this error since its set up as far as i can tell the same as the player controller. If anyone could help i would be greatful.
PlayerController
using UnityEngine;
using System.Collections;
public class PlayerController : MonoBehaviour {
//Speed
public float maxSpeed = 1f;
//Facing
public bool facingRight = true;
//Animator
private Animator anim;
//Falling / Grounded
private bool grounded = false;

private float groundRadius = 0.2f;
public LayerMask whatIsGround;
public float jumpForce = 500f;
public bool airMovment = false;
public GameObject jumpEffect;
private bool doublejump = false;
// Use this for initialization
void Start () {
anim = GetComponent<Animator> ();
}
// Update is called once per frame
void FixedUpdate () {
//Are we Hitting any colliders in this circle (genrated circle postion,radius,what it will collide with) (true "on ground" / false "not on ground")
grounded = Physics2D.OverlapCircle(groundCheck.position,groundRadius, whatIsGround);
//Set ground animation
anim.SetBool ("Ground", grounded);
if (grounded)
doublejump = false;
anim.SetFloat ("vSpeed", GetComponent<Rigidbody2D>().velocity.y);
//turn off air movment
if (airMovment == true) {
if (!grounded)
return;
}
}
public void Move (float move, bool jump)
{
//If we are grounded and press space (single jump version)
//if (grounded && Input.GetKeyDown (KeyCode.Space)) {
//Abousle value of speed to set speed for animator.
anim.SetFloat ("Speed", Mathf.Abs (move));
//Get the component RidgitBody add a velocity to it at the rate of move times the max speed and leave y as it is.
GetComponent<Rigidbody2D>().velocity = new Vector2 (move * maxSpeed, GetComponent<Rigidbody2D>().velocity.y);
// If the input is moving the player right and the player is facing left...
if (move > 0 && !facingRight)
{
// ... flip the player.
Flip();
}
// Otherwise if the input is moving the player left and the player is facing right...
else if (move < 0 && facingRight)
{
// ... flip the player.
Flip();
}
if ((grounded || !doublejump) && jump && anim.GetBool("Ground")) {
//Set the ground animation to false
anim.SetBool("Ground", false);
//Add a force to our Rigidbody2D on the y axis
GetComponent<Rigidbody2D>().AddForce(new Vector2(0,jumpForce));
//If we are grounded
if (grounded)
{
//Create effect
GameObject jumpE = Instantiate (jumpEffect, transform.position, Quaternion.identity) as GameObject;
Destroy(jumpE,0.2f);
}
//Double jump (if we are not on the ground and have not double jumped then.. set it true
if(!doublejump && !grounded)
{
doublejump = true;
}
}
}
private void Flip()
{
// Switch the way the player is labelled as facing.
facingRight = !facingRight;
// Multiply the player's x local scale by -1.
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}
}

}
//released
if (attack3) {
//Set drawn and hold to false
b_Anim.SetBool ("Drawn", false);
b_Anim.SetBool ("Hold", false);
//change release to true (since we released the arrow
release=true;
//Play the animation
b_Anim.SetBool ("Release", release);
//Change firing to false
isFiring = false;
Debug.Log ("Release");
//Shoot Arrow
//Create Arrow and set its postion and as Rigidbody2D.
var createArrow = Instantiate (shotArrow, transform.position, Quaternion.identity) as Rigidbody2D;
//Get the players direction from player controller
PlayerController direction = GetComponent<PlayerController>();
//Store it in a variable
bool dir = direction.facingRight;
if (dir)
{
//Add Velocity to the right at speed.
createArrow.velocity = transform.right * arrowSpeed;
}
else
{
createArrow.velocity = -transform.right * arrowSpeed;
}
//Create a arrow and add aforce to it on a vector 2 to the right by the speed.
//createArrow.AddForce(Vector2.right * arrowSpeed);
}
}
}
The issue seems to be with the passing infromation between the two scripts i think
Thanks for your help in advance! =]
