How could I transform keyboard input into touch input?

Hello! I’m making a racing game and I wanted to port it over to mobile, but I’m having a lot of trouble trying to figure out the best way to do it. Initially, I thought that simulating a keypress with a UI button would work well but thanks to the help of @Hellium I’m now trying to figure out another way to port this game over. Here is the current code for the BaseInput:
using UnityEngine;
namespace KartGame.KartSystems
{
public struct InputData
{
public bool Accelerate;
public bool Brake;
public float TurnInput;
}

     public interface IInput
     {
         InputData GenerateInput();
     }
 
     public abstract class BaseInput : MonoBehaviour, IInput
     {
         /// <summary>
         /// Override this function to generate an XY input that can be used to steer and control the car.
         /// </summary>
         public abstract InputData GenerateInput();
     }
 }

And here is the keyboard input script, these “horizontal”, “accelerate” and “brake” buttons are all referencing to Unity’s input manager, as you can see in the image attached!

using UnityEngine;

    namespace KartGame.KartSystems {
    
        public class KeyboardInput : BaseInput
    
        {
            public string TurnInputName = "Horizontal";
            public string AccelerateButtonName = "Accelerate";
            public string BrakeButtonName = "Brake";
    
            public override InputData GenerateInput() {
                return new InputData
                {
                    Accelerate = Input.GetButton(AccelerateButtonName),
                    Brake = Input.GetButton(BrakeButtonName),
                    TurnInput = Input.GetAxis("Horizontal")
                };
            }
        }
    }

What would be the best way to change this keyboard input method to a mobile-compatible one? Ideally, I would like a joystick for movement but left and right buttons would also be fine. Thanks again @Hellium for the help with the previous incorrect question that I’ve made!

The solution I suggested in the other question works perfectly fine

UiInput.cs

To be attached to an empty gameObject

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class UiInput : BaseInput
{
    private bool accelerate;
    private bool brake;
    private float turn;

    // Called by OnPointerDown event from Even Trigger attached to UI object
    // https://youtu.be/3NBYqPAA5Es?t=194
    public void StartAccelerate() => accelerate = true;

    // Called by OnPointerUp event from Even Trigger attached to UI object
    // https://youtu.be/3NBYqPAA5Es?t=194
    public void StopAccelerate() => accelerate = false;

    public void StartBrake() => brake = true;
    public void StopBrake() => brake = false;

    public void StartTurnLeft() => turn = Mathf.Max(turn - 1, -1);
    public void StopTurnLeft() => turn = Mathf.Min(turn + 1, 1);

    public void StartTurnRight() => turn = Mathf.Min(turn + 1, 1);
    public void StopTurnRight() => turn = Mathf.Max(turn - 1, -1);

    public override InputData GenerateInput()
    {
        return new InputData
        {
            Accelerate = accelerate,
            Brake = brake,
            TurnInput = turn
        };
    }
}

Then, for every UI button, attach an event trigger and provide the appropriate function

Example for the accelerate button:

What do I do about this errors?

I’ve done everything exactly as you specified and it is still not working, the buttons aren’t doing anything when pressed, what am I doing wrong? What information could I provide you to help you troubleshoot this?
