How can I make my player jump smooth

Unity Engine
1

Hello,
I started using Unity about 4 days ago. So sorry from the beginning that the question will probably be pretty stupid.
I have written my current script together through various tutorials.
Now I tried to make my player jump. This works, but only so that he is teleported in the air and then lands again. What do I have to do differently so he jumps into the air? I hope the question is not too stupid. Maybe someone can help me. Thanks here is my hole Script.

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

public class PlayerMovement2 : MonoBehaviour
{
    public Transform cam;
    public CharacterController controller;
    public float speed = 6f;
    public float turnSmoothTime = 0.1f;
    float turnSmoothVelocity;
    public float gravity;
    private float currentGravity = 0f;
    public float jumpSpeed;

    // Start is called before the first frame update
    void Start()
    {
       
    }

    // Update is called once per frame
    void Update()
    {
        float horizontal = Input.GetAxisRaw("Horizontal");
        float vertical = Input.GetAxisRaw("Vertical");
        Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;
        Vector3 finalMovement;
        if (direction.magnitude >= 0.1f)
        {
            float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y;
            float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
            transform.rotation = Quaternion.Euler(0f, angle, 0f);
            Vector3 moveDir = Quaternion.Euler(0f, targetAngle, 0f) * Vector3.forward;
            finalMovement = moveDir.normalized * speed + ApplyGravity();
            if (Input.GetButtonDown("Jump") && controller.isGrounded)
            {
               
                finalMovement.y = jumpSpeed;
                finalMovement.y -= gravity * Time.deltaTime;
                controller.Move(finalMovement * Time.deltaTime);
            }
            else
            {
                controller.Move(finalMovement * Time.deltaTime);
            }
        }
        else
        {
            finalMovement = ApplyGravity();
            if (Input.GetButtonDown("Jump") && controller.isGrounded)
            {
                finalMovement.y = jumpSpeed;
                finalMovement.y -= gravity * Time.deltaTime;
                controller.Move(finalMovement * Time.deltaTime);
            }
            else
            {
               
                controller.Move(finalMovement * Time.deltaTime);
            }
        }
    }

    Vector3 ApplyGravity()
    {
        Vector3 gravityMovement = new Vector3(0, -currentGravity, 0);
        currentGravity += gravity * Time.deltaTime;

        if (controller.isGrounded)
        {
            if (currentGravity > 1f)
            {
                currentGravity = 1f;
            }
        }

        return gravityMovement;
    }
}

I’m having a little trouble following what the intention is with your code. This is partly because of confusing variable names. currentGravity is added to by… gravity? You set the Y position to the … speed value? Clearly whatever those variables they are, their names are wrong. The compiler doesn’t care what you name your variables, but naming them well is the only way you’ll ever keep them straight in your head.

I think this variable confusion is making gravity a lot harder than it needs to be, which is:

  1. One persistent Vector3 variable, representing velocity
  2. Each frame, velocity += gravity * Time.deltaTime
  3. Each frame, position += velocity * Time.deltaTime
    And that’s really it. Once you have that, jumping is literally just setting velocity to Vector3(0, jumpSpeed, 0), and you don’t need to do any other logic on it. The velocity will then modify the position value according to the logic that already exists, making your character jump

Ok thanks I hope I understood it. By the Way these different Variables are the same like in the Tutorials I watched. Anyway thanks for your help I will try it.
