Diagonal Movement Question

Archived Forums Questions & Answers

When performing a physics.raycast to determine if something is hit, how would I go about overriding my diagonal movement with vertical or horizontal in the 3d space. my movement uses this,

void Update()
    {
        movePlayer.x = Input.GetAxisRaw("Horizontal") * Time.deltaTime;
        movePlayer.z = Input.GetAxisRaw("Vertical") * Time.deltaTime;
    }
    //-----//
    void FixedUpdate()
    {
        Move();
    }
    //-----//
    void Move()
    {
        var velocity = new Vector3(movePlayer.x, 0, movePlayer.z).normalized * movementVelocity;

        velocity.y = playerRigidbody.velocity.y;
        playerRigidbody.velocity = velocity;
    }

I only want to override the diagonal if I hit something in that direction.

So I watched Code monkies video, but my horizontal movement, wont work im throwing 2 different raycasts for some reason.

 void FixedUpdate()
    {
        Move();
        Jump();
    }
    //-----//
    void Move()
    {
        RaycastHit sensor1;

        

        Vector3 movement = new Vector3(moveDirection.x, 0, moveDirection.z).normalized;

        Vector3 targetPostion = movement * movementVelocity;
        Physics.Raycast(transform.position, moveDirection, out sensor1, 1);
        Debug.DrawLine(transform.position, sensor1.point, Color.red);
        targetPostion.y = playerRigidbody.velocity.y;
        playerRigidbody.velocity = targetPostion;
        if (sensor1.collider == null)
        {
            lastMoveDirection = moveDirection;
            playerRigidbody.velocity = targetPostion;
            Debug.Log("Haven't Hit");
        }
        else
        {
            Vector3 testingDirection = new Vector3(moveDirection.x = 0, 0, moveDirection.z).normalized;
            targetPostion = testingDirection * movementVelocity;
            Physics.Raycast(transform.position, testingDirection, out sensor1, 1);
            Debug.DrawLine(transform.position, sensor1.point, Color.red);
            Debug.Log("Hitting Things");
            if(testingDirection.z != 0 && sensor1.collider == null)
            {
                lastMoveDirection = testingDirection;
                playerRigidbody.velocity = targetPostion;
                Debug.Log("Haven't Hit");
            }
            else
            {
                testingDirection = new Vector3(moveDirection.x, 0, moveDirection.z = 0).normalized;
                targetPostion = testingDirection * movementVelocity;
                Physics.Raycast(transform.position, testingDirection, out sensor1, 1);
                Debug.DrawLine(transform.position, sensor1.point, Color.red);
                Debug.Log("Hitting Things");
                if (testingDirection.x != 0 && sensor1.collider == null)
                {
                    lastMoveDirection = testingDirection;
                    playerRigidbody.velocity = targetPostion;
                    Debug.Log("Haven't Hit");
                }
            }
        }     
    }
