Rigidbody rolls and falls strangely

Questions & Answers

Hello, I am new to Unity and I just started trying to create a platform 2D and I have a small problem. My character falls rolling around and get down always falling, without being on feet. If it gets too fast or hits something it starts rolling. I would like it not to roll and to fall straight down, without turning around and things like that, even because if it isn’t on feet, my groundCheck doesn’t work and I can’t jump anymore.

Here’s the code :
public class PlayerController : MonoBehaviour {

public float maxSpeed = 10f;
bool facingRight = true;

Animator anim;

public Transform GroundCheck;
public LayerMask WhatIsGround;
bool grounded = false;
float groundRadius = 0.2f;

bool doubleJump = false;
public float jumpForce = 70f;

// Use this for initialization
void Start () {
	anim = GetComponent<Animator> (); 
}

void FixedUpdate(){

	grounded = Physics2D.OverlapCircle (GroundCheck.position, groundRadius, WhatIsGround);

	anim.SetBool ("Ground", grounded);

	if (grounded)
					doubleJump = false;
	if (!grounded)
					return;

	float move = Input.GetAxis ("Horizontal");

	anim.SetFloat ("Speed", Mathf.Abs(move));

	rigidbody2D.velocity = new Vector2(move * maxSpeed, rigidbody2D.velocity.y);

	if (move > 0 && !facingRight)
					Flip ();
			else if (move < 0 && facingRight)
					Flip ();

}

void Update()
{
	if ((grounded || !doubleJump) && Input.GetKeyDown (KeyCode.UpArrow)) {
		anim.SetBool("Ground",false);
		rigidbody2D.AddForce(new Vector2(0,jumpForce));

		if(!doubleJump && !grounded)
			doubleJump = true;
	}
}
void OnCollisionEnter2D(Collision2D collision)
{
	if(collision.gameObject.name == "GoldCoin")
		Destroy (collision.gameObject);
}
void Flip(){
	facingRight = !facingRight;
	Vector3 theScale = transform.localScale;
	theScale.x *= -1;
	transform.localScale = theScale;
}

}

Thanks!

I believe you need to select “Fixed Angle” in the inspector for your sprite/object.
