Creating Unity Swerve Input

 Hello everyone, in this post I will show you what kind of code should be written for the Swerve mechanic in Unity.

I am leaving the code below and, with comment lines, I will explain what we are doing at each part.

using UnityEngine;

// ReSharper disable once CheckNamespace
namespace UrhobA.Inputs.Swerve
{
    public class Mouse : MonoBehaviour
    {
        private Vector2
            _startedPos, // position where the movement started
            _delta; // position where the movement continues

        private Vector2 _value; // the value reflected as a result of the movement

        public Vector2 GetValue() // This function will be called from the script where we write our character movement and will be included in the movement code.
        {
            return _value;
        }
        public float maxDistance = 100f; // the maximum amount the user's movement can be
        
        #region System Functions
        private void Update()
        {
            if (Input.GetMouseButtonDown(0))
                _startedPos = (Vector2) Input.mousePosition; // we get the starting position

            if (Input.GetMouseButtonUp(0))
            { 
            // We reset values when the movement is over
                _delta = Vector2.zero; 
                _startedPos = Vector2.zero;
                _value = Vector2.zero;
            }

            if (!Input.GetMouseButton(0)) return; // if it's moving, we do the calculations
            _delta = (Vector2) Input.mousePosition - _startedPos;
            _delta.x = Mathf.Clamp(_delta.x, -maxDistance, maxDistance);
            _delta.y = Mathf.Clamp(_delta.y, -maxDistance, maxDistance);

            _value = _delta / maxDistance;
            _startedPos = (Vector2) Input.mousePosition;
        }
        #endregion
    }
}
