How to get a game object to jump forward

Unity Engine

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.

using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
//VARIABLES
[SerializeField] private float moveSpeed;
[SerializeField] private float walkSpeed;
[SerializeField] private float runSpeed;
private Vector3 moveDirection;
private Vector3 velocity;
[SerializeField] private bool isGrounded;
[SerializeField] private float groundCheckDistance;
[SerializeField] private LayerMask groundMask;
[SerializeField] private float gravity;
[SerializeField] private float jumpHeight;

//REFERENCES
private CharacterController controller;
private Animator anim;
private Collider Collider;

private void Start()
{
controller = GetComponent();
anim = GetComponentInChildren();
Collider = GetComponent(); ;
}

private void Update()
{
Move();
}

private void Move()
{
isGrounded = Physics.CheckBox(Collider.bounds.center, Collider.bounds.extents, transform.rotation, groundMask);

if (isGrounded && velocity.y < 0)
velocity.y = -2f;

float moveZ = Input.GetAxis(“Vertical”);
moveDirection = new Vector3(0, 0, moveZ);
moveDirection = transform.TransformDirection(moveDirection);

if (isGrounded)
{

if (moveDirection != Vector3.zero && !Input.GetKey(KeyCode.LeftShift))
{
Walk();
}
else if (moveDirection != Vector3.zero && Input.GetKey(KeyCode.LeftShift))
{
Run();
}
else if (moveDirection == Vector3.zero)
{
Idle();
}

moveDirection *= moveSpeed;

if (isGrounded && Input.GetKeyDown(KeyCode.Space) && moveDirection == Vector3.zero )
{
Jump();
}

if (isGrounded && Input.GetKeyDown(KeyCode.Space) && Input.GetKey(KeyCode.W) && moveDirection != Vector3.zero)
{
JumpFor();
}

anim.SetBool(“Jump”, false);
anim.SetBool(“JumpUp”, false);
}

if (!isGrounded)
anim.SetBool(“Jump”, true);

controller.Move(moveDirection * Time.deltaTime);

velocity.y += gravity * Time.deltaTime;
controller.Move(velocity * Time.deltaTime);
}

private void Idle()
{
anim.SetFloat(“Speed”, 0, 0.02f, Time.deltaTime);
}

private void Walk()
{
moveSpeed = walkSpeed;
anim.SetFloat(“Speed”, 0.6f, 0.1f, Time.deltaTime);
}

private void Run()
{
moveSpeed = runSpeed;

anim.SetFloat(“Speed”, 1, 0.1f, Time.deltaTime);
}

private void Jump()
{
velocity.y = Mathf.Sqrt(jumpHeight * -2 * gravity);
}

private void JumpFor()
{
velocity.y = Mathf.Sqrt(jumpHeight * -2 * gravity);
}
}

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.
