NullReferenceException: UnityEngine.Rigidbody2D.get_velocity()
I get this null exception every time i try to move my character, I am trying to move my character using 2 different methods. I am new to Unity coming from Monogame and XNA. Here is my code:
private Rigidbody2D _rig;
void Start(){
_rig = GetComponent<Rigidbody2D>();
void Update(){
_position.x = Input.GetAxis ("Horizontal");
_position.y = Input.GetAxis ("Vertical");
}
void FixedUpdate () {
if (Input.GetKeyDown(KeyCode.Space))
{
_rig.AddForce(new Vector2(_rig.velocity.x, _jumpHeight));
_rig.velocity = new Vector2(Mathf.Clamp(_rig.velocity.x, -_clampValue.x, _clampValue.x), Mathf.Clamp(_rig.velocity.y, -_clampValue.y, _clampValue.y));
}
if (Input.GetKey(KeyCode.D))
{
//_rig.AddForce(new Vector2(_moveSpeed, _rig.velocity.x));
//_rig.velocity = new Vector2(Mathf.Clamp(_rig.velocity.x, -_clampValue.x, _clampValue.x), Mathf.Clamp(_rig.velocity.y, -_clampValue.y, _clampValue.y));
_rig.velocity = new Vector2(_position.x * _moveSpeed, _rig.velocity.y);
}
if (Input.GetKey(KeyCode.A))
{
_rig.AddForce(new Vector2(-_moveSpeed, _rig.velocity.y));
_rig.velocity = new Vector2(Mathf.Clamp(_rig.velocity.x, -_clampValue.x, _clampValue.x), Mathf.Clamp(_rig.velocity.y, -_clampValue.y, _clampValue.y));
}
}
Do you have Rigidbody2D on object which contains this script? Do you assign its Rigidbody2D to your _rig variable? If you have and you do then show how you do that.
I believe you just forgot closing bracket in Start function while you were posting here and you have defined all your variables. I believe as well that you've rechecked from my previous comment that you have Rigidbody2D, though just in case you can verify that:
private Rigidbody2D _rig;
void Start()
{
_rig = GetComponent<Rigidbody2D>();
Debug.Log(_rig != null);
}
But what I'd really want you to do now - post the actual error along with pointing out to which line of code here it refer.
