new input system conversion

[civic terrace]

using UnityEngine;

public class CarInputHandler : MonoBehaviour
{
    //Components
    TopDownCarController topDownCarController;

    void Awake()
    {
        topDownCarController = GetComponent<TopDownCarController>();
    }

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        Vector2 inputVector = Vector2.zero;

        inputVector.x = Input.GetAxis("Horizontal");
        inputVector.y = Input.GetAxis("Vertical");

        topDownCarController.SetInputVector(inputVector);

        Debug.Log($"Input Vector: {inputVector}");
    }
}

my current code

it works perfectly with the old input system

for reference this is the tutorial I've been following

https://youtu.be/DVHcOS1E5OQ?si=Y7PfybkE7Xv9JaBw

anyways for now I only have one object which is the Car player

it has two scripts assigned to it, one is only there for physics which is this one

using UnityEngine;

public class TopDownCarController : MonoBehaviour
{
    [Header("Car settings")]
    public float driftFactor = 0.95f;
    public float accelerationFactor = 30.0f;
    public float turnFactor = 3.5f;
    public float maxSpeed = 20;

    //local variables
    float accelerationInput = 0;
    float steeringInput = 0;

    float rotationAngle = 0;

    float velocityVsUp = 0;

    //Components
    Rigidbody2D carrigidbody2D;

    void Awake()
    {
        carrigidbody2D = GetComponent<Rigidbody2D>();
    }

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

    }

    void FixedUpdate()
    {
        ApplyEngineForce();
        KillOrthogonalVelocity();
        ApplySteering();
    }

    void ApplyEngineForce()
    {
        //Calculate how fast we are going forwards in terms of the direction of our velocity
        velocityVsUp = Vector2.Dot(transform.up, carrigidbody2D.linearVelocity);

        //Limit so we cannot go faster than the speed limit in the forward direction
        if (velocityVsUp > maxSpeed && accelerationInput > 0)
        {
            return;
        }

        //Limit so we cannot go faster than the speed limit while reversing
        if (velocityVsUp < -maxSpeed * 0.5f && accelerationInput < 0)
        {
            return;
        }

        //Limit so we cannot go faster than the speed limit while accelearting
        if (carrigidbody2D.linearVelocity.sqrMagnitude > maxSpeed * maxSpeed && accelerationInput > 0)
        {
            return;
        }

        //Apply linear damping if there is no accelerationInput so the car stops if the player lets go of the accelerator
        if (accelerationInput == 0)
        {
            carrigidbody2D.linearDamping = Mathf.Lerp(carrigidbody2D.linearDamping, 3.0f, Time.fixedDeltaTime * 3);
        }
        else
        {
            carrigidbody2D.linearDamping = 0;
        }

        //Create a force for the engine
        Vector2 engineForceVector = transform.up * accelerationInput * accelerationFactor;

        //Apply force that push car forwards
        carrigidbody2D.AddForce(engineForceVector, ForceMode2D.Force);

    }

    void ApplySteering()
    {
        //Limit car steering based on speed
        float minSpeedBeforeAllowTurningFactor = (carrigidbody2D.linearVelocity.magnitude / 8);
        minSpeedBeforeAllowTurningFactor = Mathf.Clamp01(minSpeedBeforeAllowTurningFactor);

        //Update the rotation angle based on Input
        rotationAngle -= steeringInput * turnFactor * minSpeedBeforeAllowTurningFactor;

        //Apply steering by rotating the car object
        carrigidbody2D.MoveRotation(rotationAngle);
    }

    public void KillOrthogonalVelocity()
    {
        Vector2 forwardVelocity = transform.up * Vector2.Dot(carrigidbody2D.linearVelocity, transform.up);
        Vector2 rightVelocity = transform.right * Vector2.Dot(carrigidbody2D.linearVelocity, transform.right);

        carrigidbody2D.linearVelocity = forwardVelocity + rightVelocity * driftFactor;
    }

    public void SetInputVector(Vector2 inputVector)
    {
        steeringInput = inputVector.x;
        accelerationInput = inputVector.y;
    }
}

I doubt it's relevant to the issue but I decided to share it

and there the other one I shared above at the start of the thread

so all in all, what I want to is to migrate to the new input system, that's it

What did you try?

This is just a "how do I migrate to the new system"?

[civic terrace]

I did create this

but I am not sure how to link it

I assume I have to replace this part

    void Update()
    {
        Vector2 inputVector = Vector2.zero;

        inputVector.x = Input.GetAxis("Horizontal");
        inputVector.y = Input.GetAxis("Vertical");

        topDownCarController.SetInputVector(inputVector);

        Debug.Log($"Input Vector: {inputVector}");
    }

You should read this: https://docs.unity3d.com/Packages/com.unity.inputsystem@1.14/manual/Migration.html

o7 right away

okay so I managed to make it work \o/

but I kinda messed up the steering XD

auuuuuugh

forwards backwards is working fine but steering is
