How to make an object jump forward? - c#

I've been having problems with getting my character to jump Forward. I've got it set to jump in place but I can't seem to get the JumpFor() to move forward as it jumps. I've tried Vector3 but it only works in 1 direction and transform.forward doesn't seem to work at all.

I Solved it. I ended up using the velocity vector in JumpFor() and gave it a new Vector3 Then I put velocity= transform.TransformDirection(velocity) so it uses the local axis instead of the global one. After that is et it so velocity = Vector3.zero when the player grounds.

<RigidBody> Controller

I am working on a rigidbody controller and as of right now it has some issues I cant solve. I would like my movement to be continous and if though i am checking if the player is grounded it is still jumping while in the air. Thanks in advance for any feedback its greatly appreciated!
using UnityEngine;
using UnityEngine.InputSystem;
public class Player : MonoBehaviour
{
private Rigidbody _playerRB;
private PlayerInputSystem _playerInput;
private float playerIdNumber;
private string uniquePlayName;
private float jumpForce = 10.0f;
[Header("IsGounded")]
public LayerMask whatIsGround;
public Transform groundCheck;
private float groundCheckRadius = 0.1f;
private float speed = 10.0f;
private float acceleration = 1.0f;
private float currentSpeed;
private void Awake()
{
_playerRB = GetComponent<Rigidbody>();
_playerInput = new PlayerInputSystem();
_playerInput.Player.Enable();
}
private void OnEnable()
{
_playerInput.Player.Jump.performed += Jump;
_playerInput.Player.Move.performed += Move;
}
private void OnDisable()
{
_playerInput.Player.Jump.performed -= Jump;
_playerInput.Player.Move.performed -= Move;
}
private void Jump(InputAction.CallbackContext obj)
{
if (Physics.CheckSphere(groundCheck.position, groundCheckRadius, whatIsGround))
{
_playerRB.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
}
}
private void Move(InputAction.CallbackContext obj)
{
float horizontal = obj.ReadValue<Vector2>().x;
float vertical = obj.ReadValue<Vector2>().y;
transform.rotation *= Quaternion.Euler(new Vector3(0, horizontal, 0));
currentSpeed += vertical * acceleration * Time.deltaTime;
currentSpeed = Mathf.Clamp(currentSpeed, 0, speed);
transform.position += transform.right * currentSpeed * Time.deltaTime;
}
}
Again thanks in advance for the help.

After adding gravity I can't run and walk faster

I'm trying to make move script but it seems impossible to me because I stared at code for like an hour I even rewrote it but same problem. It appears that after I added gravity and groundcheck things, my character cant run or even walk at set speed (he is moving very slow). Can someone please help me with it please cuz' I'm lost

I found the problem. Problem was with spawn area or call it how you want. If you'll move further the problem is no longer there.
Look at this video here: https://youtu.be/xfxgwmuPQsA

Why it says expected ',' but i don't see why to use it

The problem is with KeyCode."W"
This should be KeyCode.W

character mesh is going underneath the character controller

I'm not sure if someone is going to help me with this problem but here is my issue any ways
My player movement script was working perfectly fine before I enter this code and I'm pretty sure it's something in my script from the past that is causing my character mesh to have a huge offset downwards from my character controller yes, I have the curves set up probably here is the Ik tutorial I followed to get this issue.

my player can fly for some reason, i have gravity on the rigidbody of the player

Im trying to make a 3d game with unity, but i dont know how to implement gravity, so i turned gravity for the rigidbody on. Also how could i implement jumping and wallrunning into this code?
using System.Collections;
using System.Collections.Generic;

rb.freezeRotation = true;
}
bool isGrounded;
private void Update()
{

print (isGrounded);
MyInput();
}

verticalMovement = Input.GetAxisRaw("Vertical");
