Rotation movement

Questions & Answers
1

i used this code to rotate the player based on where it goes

if (movementDirection != Vector3.zero)
{
    Quaternion toRotation = Quaternion.LookRotation(movementDirection, Vector3.up);
    transform.rotation = Quaternion.RotateTowards(transform.rotation, toRotation, rotationSpeed * Time.deltaTime);
}

Now i need to rotate the player for a certain angle if it moves on the x (input: horizontal).

if (movementDirection.x != 0) { /*abracadabra*/ }

_
So I have the camera in the middle and the player that moves around as it moves:

rotate around point
(red is your camera, green is player)

Transform subject = player.transform;
Vector3 initialPosRelative = subject.position - pivot;
Quaternion initialRotation = subject.rotation;
Vector3 pivot = cameraTransform.position;
Vector3 axis  =  cameraTransform.up;// < < axis of rotation
float rotationSpeed = 10f;    
float t = rotationSpeed * Time.deltaTime;
Quaternion rot = Quaternion.AngleAxis( angle * t , axis );

subject.position = pivot + rot * initialPosRelative;
subject.rotation = initialRotation * rot;

Code is not tested but you should get the idea: rotate relative position around an axis.

I don’t think we understood each other …
or I’m the one who doesn’t understand what you showed me
but I need my third person character to be able as he goes left or right to walk a path in a circle

As you see in the image:
in the middle there is the camera and my character who goes to the right walks facing right “around the room that looks at him” @andrew-lukasik

Well, give this one a try. This time, you’ll have to create an empty child gameobject of the camera, and remember to handle that animator part.

Vector3 desiredMoveDirection;
    Vector3 lastMoveDirection;
    Transform camLock;

    public Camera cam;
    public Transform camChild;

    public float desiredRotationSpeed;

    float distance;
    bool isTurning;

    void Update()
    {
        //Make the camChild y position the same as the player
        if (!isTurning)
            camChild.transform.position = new Vector3(cam.transform.position.x, transform.position.y, cam.transform.position.z);
        float horizontalInput = Input.GetAxisRaw("Horizontal");
        float verticalInput = Input.GetAxisRaw("Vertical");

        Vector3 movementDirection = new Vector3(horizontalInput, 0, verticalInput);

        var forward = cam.transform.forward;
        var right = cam.transform.right;

        forward.y = 0f;
        right.y = 0f;

        forward.Normalize();
        right.Normalize();

        if (movementDirection != Vector3.zero)
        {
            desiredMoveDirection = forward * movementDirection.z + right * movementDirection.x;
            lastMoveDirection = desiredMoveDirection;
            //When the player does press W or S
            if (verticalInput != 0)
            {
                Quaternion toRotation = Quaternion.LookRotation(lastMoveDirection, Vector3.up);
                transform.rotation = Quaternion.Slerp(transform.rotation, toRotation, desiredRotationSpeed);

            }

            //Test when the player press D
            else
            {
                if (Input.GetKey(KeyCode.D) && !isTurning)
                {
                    //Turn
                    camLock = camChild.transform;
                    distance = (transform.position - camLock.position).magnitude;
                    newRotation = new Vector3(camChild.transform.eulerAngles.x, camChild.transform.eulerAngles.y + 90, camChild.transform.eulerAngles.z);
                    isTurning = true;
                    StartCoroutine(TurnRight());
                }
            }
        }

        anim_Warrior(movementDirection);
    }

    Vector3 newRotation;

    IEnumerator TurnRight()
    {
        while (camChild.transform.rotation != Quaternion.Euler(newRotation))
        {
            //Rotate the camChild gameObject to set the path for the player
            camChild.transform.SetPositionAndRotation(camLock.position, Quaternion.Lerp(camChild.transform.rotation, Quaternion.Euler(newRotation), Time.deltaTime));
            //make the player rotate and move in a curve path
            transform.SetPositionAndRotation(camChild.transform.position + camChild.transform.forward * distance, Quaternion.LookRotation(camChild.transform.right));


            //Write some code here to make the animator play that walking animation
            //Such as anim_Warrior(movementDirection) but now the movementDirection is now zero so try something else
            yield return null;
        }
        isTurning = false;
        transform.rotation = Quaternion.LookRotation(transform.right * -1);

        //Do something to stop walking the animation
    }

No that’s not what I’m saying … @eneIr

This is my movement code. The player have 3 functions (Rotate to direction, Rotate to camera facing, “Curve if it goes horizontal”

But now i have another problem … First play it works… after my player doesnt move. IDK

void Update()
    {

        float horizontalInput = Input.GetAxisRaw("Horizontal");
        float verticalInput = Input.GetAxisRaw("Vertical");

        Vector3 movementDirection = new Vector3(horizontalInput, 0, verticalInput);

        var camera = Camera.main;
        var forward = cam.transform.forward;
        var right = cam.transform.right;

        forward.y = 0f;
        right.y = 0f;

        forward.Normalize();
        right.Normalize();

        
        desiredMoveDirection = forward * movementDirection.z + right * movementDirection.x;

        if (movementDirection != Vector3.zero)
        {

            lastMoveDirection = desiredMoveDirection;

        }

        Quaternion toRotation = Quaternion.LookRotation(lastMoveDirection, Vector3.up);
        transform.rotation = Quaternion.Slerp(transform.rotation, toRotation, desiredRotationSpeed);

        // THIS IS THE CODE I AM TRYING TO DO
        // IF horizontalInput the player walks turning 
        // so it doesn't go straight but it takes a curve

        /*if(movementDirection.x != 0)  
        {
            Vector3 angleRotation = new Vector3(0, angle, 0);
            transform.transform.Rotate(angleRotation, Space.World);
        }*/


        anim_Warrior(movementDirection);
    }

This is what happens @eneIr
sorry for my headless player. I didn’t want to scandalize anyone …
