Jump while running not faster than normal jump. Any help with the code?

Hi everyone!

I found and adapted this piece of code to create a simple character controller. Everything works as I need except for jump: if the character walks (or stands still) and then jump there are no problems but if I make it run and then press the jump button, the jump movement is identical to when it walks. I expect him to have a longer and faster jump but it doesn’t happen!

Here’s the code (please ignore everything related to the animator):

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

public class PlayerControllerMouseNOROOT : MonoBehaviour
{
public CharacterController controller;
private Animator anim;
private float x = 0.0f;
private float z = 0.0f;

[SerializeField] private float walkSpeed = 2.0f;
[SerializeField] private float runSpeed = 6.0f;
[SerializeField] private float jumpHeight = 3.0f;
[SerializeField] private float rotSpeed = 4.0f;

private float speed = 0.0f;
private float rotation = 0.0f;

[SerializeField] private Transform groundCheck;
[SerializeField] private float groundDistance = 0.4f;
[SerializeField] private LayerMask groundMask;
public bool isGrounded;
[SerializeField] private float gravity = -19.62f;
private Vector3 velocity;

// Start is called before the first frame update
void Start()
{
controller = GetComponent<CharacterController>();
anim = GetComponent<Animator>();
}

// Update is called once per frame
void Update()
{
// Check to see if player is grounded
isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);

if (isGrounded && velocity.y < 0)
{
velocity.y = -2.0f;
anim.SetBool("isGrounded", true);
}

// Player movement and sprint
x = Input.GetAxis("Horizontal");
z = Input.GetAxis("Vertical");
rotation = x;
anim.SetFloat("Rotation", rotation);

if (z != 0f)
{ 
if (z > 0)
{
speed = walkSpeed;
anim.SetFloat("Speed", 1.0f);
}
else
{
speed = walkSpeed;
anim.SetFloat("Speed", -1.0f);
}

if (Input.GetButton("Sprint") && isGrounded && z > 0)
{
speed = runSpeed;
anim.SetFloat("Speed", 2.0f);
}
}
else
{
speed = 0f;
anim.SetFloat("Speed", 0f);
}

Vector3 move = Vector3.Normalize(transform.right * x + transform.forward * z);

move *= speed;

velocity.y += gravity * Time.deltaTime;

controller.Move(move * Time.deltaTime);

controller.Move(velocity * Time.deltaTime);

transform.Rotate(0, x * rotSpeed, 0);

// Jump
if (Input.GetButtonDown("Jump") && isGrounded)
{
isGrounded = false;
velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
anim.SetTrigger("isJumping");
anim.SetBool("isGrounded", false);
}

}

}

Thank you in advance for your help!

The x velocity when jumping should be the same it was before jumping… not sure why it wouldn’t be… my guess is you are setting the speed just before or during the jump. if you want jumps to be faster you can increase the x velocity when you jump… if you multiply it then it won’t affect jumping straight up.
How did you set velocity.y without creating a new vector?

Here you set speed to walkSpeed regardless of what z equals:

if (z > 0)
{
speed = walkSpeed;
anim.SetFloat(“Speed”, 1.0f);
}
else
{
speed = walkSpeed;
anim.SetFloat(“Speed”, -1.0f);
}

You also set grounded to true if the y velocity is negative that means you are grounded as soon as you are falling, so you should be getting multiple jumps.
