Moving code

Unity Engine

I’m making a Tetris game, but i’m still stucked at moving code by touch or swipe :(, so please help me how to fix it

    void Update() {
        if (State != TetrimoState.Fixed && State != TetrimoState.Preview && State != TetrimoState.Spawning) {
            if (State != TetrimoState.Landed && Input.GetAxis("Vertical") < 0)
                StartCoroutine(FallingDown());

            if (Input.GetButtonDown("Horizontal") )
                StartCoroutine(MoveHorizontal());

            if ((Input.GetKeyDown(KeyCode.UpArrow) && Time.time > NextSwap)) {   
                if (this.CanRotate) {
                    StartCoroutine(RotateTetrimo());
                    NextSwap = Time.time + SwapCooldown;
                }
            }

            // Automatic falling down
            if (NextFall < 0) {
                StartCoroutine(FallingDown());
                NextFall = FallingCooldown;
            }
            NextFall -= FallingSpeed * Time.deltaTime;
        }
    }

here the move right, left and down

    IEnumerator MoveHorizontal() {
        IsMovingHorizontal = true;

        float moved     = 0.0f;
        float direction = Input.GetAxis("Horizontal");

        if ((this.CanMoveRight && direction > 0) || (this.CanMoveLeft && direction < 0)) {
            while (moved <= 1.0f) {
                float moveStep = Mathf.Min(HorizontalSpeed * Time.deltaTime, 1.1f - moved);   // 1.1f since float has some rounding problems!

                if (direction > 0)
                    transform.Translate(Vector3.right * moveStep, Space.World);
                else if (direction < 0)
                    transform.Translate(Vector3.left  * moveStep, Space.World);

                moved += moveStep;
                yield return 0;
            }

            // We will correct the actual position of each stone when it landed
            transform.position = new Vector2(Mathf.RoundToInt(transform.position.x), Mathf.RoundToInt(transform.position.y));
        }

        IsMovingHorizontal = false;
    }
    IEnumerator FallingDown() {
        if (this.CanMoveDown) {
            transform.Translate(Vector3.down, Space.World);
        }
        else {
            if (State == TetrimoState.Falling) {
                // After the Tetrimo has landed, the player can move it in the first 400ms.
                this.audio.Play();
                State = TetrimoState.Landed;
                yield return new WaitForSeconds(0.4f);
                while (IsMovingHorizontal)  // Wait for end of possible MoveHorizontal - calls
                    yield return new WaitForEndOfFrame();

                if (this.CanMoveDown) {
                    State = TetrimoState.Falling;
                }
                else {
                    State = TetrimoState.Fixed;
                    foreach (Transform child in transform) {
                        Tetrimo.FieldMatrix[Mathf.RoundToInt(child.position.y), Mathf.RoundToInt(child.position.x)] = child.gameObject;
                    }
                    ArrayList lines = FindLines();

                    if (lines.Count > 0) {
                        int FourLineBonus = 0;

and the code to check

    bool CanMoveDown {
        get {
            if(IsMovingHorizontal)
                return false;

            foreach (Transform child in transform) {
                if (Mathf.RoundToInt(child.position.y - 1) < 0 || FieldMatrix[Mathf.RoundToInt(child.position.y - 1), Mathf.RoundToInt(child.position.x)] != null)
                    return false;
            }
            return true;
        }
    }
    bool CanMoveRight {
        get {
            bool canMoveRight = true;
            foreach (Transform child in transform) {
                canMoveRight &= Mathf.RoundToInt(child.position.x + 1) <= Tetrimo.FieldSize.Right && FieldMatrix[Mathf.RoundToInt(child.position.y), Mathf.RoundToInt(child.position.x + 1)] == null;
            }
            return canMoveRight;
        }
    }
    bool CanMoveLeft {
        get {
            bool canMoveLeft = true;
            foreach (Transform child in transform) {
                canMoveLeft &= Mathf.RoundToInt(child.position.x - 1) >= Tetrimo.FieldSize.Left && FieldMatrix[Mathf.RoundToInt(child.position.y), Mathf.RoundToInt(child.position.x - 1)] == null;
            }
            return canMoveLeft;
        }
    }
    bool CanRotate {
        get {
            // Iterate through each TetrimoParts
            for (int index = 0; index < Shapes.GetLength(2); index++) {
                Vector2 tmp = new Vector2(transform.position.x, transform.position.y) + Shapes[ShapeIndex, (RotationIndex + 1) % Shapes.GetLength(2), index];

                if (tmp.x < FieldSize.Left || tmp.x > FieldSize.Right || tmp.y < FieldSize.Bottom || tmp.y > FieldSize.Top)
                    return false;

                if (FieldMatrix[Mathf.RoundToInt(tmp.y), Mathf.RoundToInt(tmp.x)] != null)
                    return false;
            }
            return true;
        }
    }

sorry for my English, please give me a hint how to do it (i don’t know how gettouch code make)

Check out the manual for mobile device input and read more about the Input.touches here.

i tried to add but failed. Sorry but can you help me where i should replace and replace what kinds of code?
