No gravity when running against a wall (2D)

I looked around and found this:

But I don’t understand how the answer worked for him.
First of all, the package is importing 3d physics materials, and I tried to play around with the 2d materials and none of the things I tried work.

The walls have 2d box collides, and the player has the same thing with a non-kinematic 2d rigidbody and the following script:

public class playerscript : MonoBehaviour {
	public float maxSpeed = 10f;
	bool facingRight = true;

	Animator anim;

	bool grounded = false;
	public Transform groundCheck = null;
	float groundRadius = 0.2f;
	public LayerMask whatIsGround;
	public float jumpForce = 700f;

	// Use this for initialization
	void Start () {
		anim = GetComponent<Animator>();
	}
	
	// Update is called once per frame
	void FixedUpdate () {
		grounded = Physics2D.OverlapCircle(groundCheck.position, groundRadius, whatIsGround);
		anim.SetBool("Ground", grounded);

		anim.SetFloat("vSpeed", rigidbody2D.velocity.y);

		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 && Input.GetKeyDown(KeyCode.Space))
		{
			anim.SetBool("Ground", false);
			rigidbody2D.AddForce(new Vector2(0, jumpForce));
		}
	}

	void Flip()
	{
		facingRight = !facingRight;
		Vector3 theScale = transform.localScale;

		theScale.x *= -1;
		transform.localScale = theScale;
	}
}

Thank you for your time :slight_smile:

So apparently… unity uses 0.4 friction as default and it should be changed to 0…
