jump not work properly

[light obsidian]

sometimes when i jump it doesnt work properly, i need to click multiple times for it to work, im following the brakeys 1st person player movement tutorial
help please.
my code: ```csharp
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{

#region Var

//Movement Var
public CharacterController CONTROLLER;
public float playerSPEED = 25f;

//Gravity Var
public float GRAVITY =  -9.81f;
Vector3 velocity;

//GroundCheck Var
public Transform groundCHECK;
public float groundDISTANCE;
public LayerMask groundMASK;
bool isGrounded = false;

//Jump Var
public float jumpHIGHT = 3F;
#endregion

// Update is called once per frame
void Update()
{

    //Input
    float x = Input.GetAxis("Horizontal");
    float z = Input.GetAxis("Vertical");

    //IsGrounded Code
    isGrounded = Physics.CheckSphere(groundCHECK.position, groundDISTANCE, groundMASK);

    velocity.y += GRAVITY * Time.deltaTime;
    if(isGrounded) {
        velocity.y = 0;
    }

    //Calcutating Direction To Move
    Vector3 move = transform.right * x + transform.forward * z;

    //Moving
    CONTROLLER.Move(move * playerSPEED * Time.deltaTime);

    //Jump
    if (Input.GetButtonDown("Jump"))
    {
        velocity.y = Mathf.Sqrt(jumpHIGHT * -2 * GRAVITY);
    }

    //Gravity
    

    CONTROLLER.Move(velocity * Time.deltaTime);
}

}```

help please

no clue what's the issue, but this line looks very wrong to me:
"Vector3 move = transform.right * x + transform.forward * z;"

[light obsidian]

Me too but it was toldin the tutorial: https://youtu.be/_QajrabyTJc
And it gets the job done

[quick ridge]

can you Debug.Log the value of isgrounded and check wether it's actually true?

[light obsidian]

It is true i used the debug mode inspector that was my first instinct

[quick ridge]

groundcheck, groundDistance and groundmask are set properly?

[light obsidian]

They are

no clue where the velocity actually gets applied, but if the velocity are absolute values, you try to jump for one frame, then set the upward velocity back to 0 on the next frame with

            velocity.y = 0;
        }```

You said this

I think it might just be it

[quick ridge]

yeh, but I can't make sense of it just yet

[light obsidian]

I'll make a work around for this if it is the problem tomm as it should s getting late for me and i gtg
