so heres my script pls help

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
public CharacterController controller;
public float speed = 12f;
public float gravity = -9.81f;
public float jumpHeight = 3f;
public Transform groundCheck;
public float groundDistance = 0.4f;
public LayerMask groundMask;
Vector3 velocity;
bool isGrounded;
// Update is called once per frame
void Update()
{
isGrounded = Physics.CheckCapsule(groundCheck.position, groundDistance, groundMask);
if(isGrounded && velocity.y < 0);
{
velocity.y = -2f;
}
float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");
Vector;3 move = transform.right * x + transform.forward * z;
controller.Move(move * speed * Time.deltaTime);
if(Input.GetButtonDown("Jump") && isGrounded);

{
velocity.y = Mathf.Sqrt(jumpHeight * -2 * gravity);
}
velocity.y += gravity * Time.deltaTime;
controller.Move(velocity * Time.deltaTime);
}
}

 

if(isGrounded && velocity.y < 0);

remove this semicolon

 

You actually have multiple if statements with semicolons at the end of them. You generally NEVER want this.

Also, please use code tags: https://forum.unity.com/threads/using-code-tags-properly.143875/

so i did but it still says i need a semicolin some where if u know pls help

 

The numbers next to the error message tell you where.
IE: (25,18) = line 25, character 18.

 

Remove the semicolon at the end of this also

if(Input.GetButtonDown("Jump") && isGrounded);

if statements should look like this:

Code (CSharp):

1. if(check = 1)
2. {
3.  
4. your code here;
5.  
6. }
7.
