Hi everybody !
I have a problem with my character controller and colliders :
My player move perfectly but when i try to pass throught a wall (with a collider on my player and on the wall) my player go on the wall and go on a (random ?) tile around the wall.

This is my script :

    Direction currentDirection;
    Vector2 input;
    bool isMoving = false;
    Vector3 startPos;
    Vector3 endPos;
    float t;

    public bool isAllowedToMove;

    public float walkspeed = 3f;

    public Sprite northSprite;
    public Sprite eastSprite;
    public Sprite southSprite;
    public Sprite westSprite;

    void Start()
    {
        isAllowedToMove = true;
    }

    void Update()
    {
        if (!isMoving && isAllowedToMove)
        {
            input = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
            if (Mathf.Abs(input.x) > Mathf.Abs(input.y))
                input.y = 0;
            else
                input.x = 0;

            if (input != Vector2.zero)
            {
                if (input.x < 0)
                {
                    currentDirection = Direction.Ouest;
                }
                if (input.x > 0)
                {
                    currentDirection = Direction.Est;
                }
                if (input.y < 0)
                {
                    currentDirection = Direction.Sud;
                }
                if (input.y > 0)
                {
                    currentDirection = Direction.Nord;
                }

                switch (currentDirection)
                {
                    case Direction.Nord:
                        gameObject.GetComponent<SpriteRenderer>().sprite = northSprite;
                        break;
                    case Direction.Est:
                        gameObject.GetComponent<SpriteRenderer>().sprite = eastSprite;
                        break;
                    case Direction.Sud:
                        gameObject.GetComponent<SpriteRenderer>().sprite = southSprite;
                        break;
                    case Direction.Ouest:
                        gameObject.GetComponent<SpriteRenderer>().sprite = westSprite;
                        break;
                }


                StartCoroutine(Move(transform));
            }
        }
    }

    public IEnumerator Move(Transform entity)
    {
        isMoving = true;
        startPos = entity.position;
        t = 0;

        endPos = new Vector3(startPos.x + System.Math.Sign(input.x), startPos.y + System.Math.Sign(input.y), startPos.z);

        while (t < 1f)
        {
            t += Time.deltaTime * walkspeed;
            entity.position = Vector3.Lerp(startPos, endPos, t);
            yield return null;
        }

        isMoving = false;
        yield return 0;
    }


    enum Direction
    {
        Nord,
        Est,
        Sud,
        Ouest
    }

Thank you,

Both walls and player needs to have a collier in order for this to work.

Could be you are using Lerp and it ignores the colliders
better approach would be to use rigidbody2d.addforce
