Bug Move script doesn't work

So I have a movement script that should allow my player capsule to move and jump. The movement works but my first-person camera starts spinning like crazy when I move. Jumping also doesn't seem to work at all.

My PlayerMovement script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerMovement : MonoBehaviour
6. {
7.     public float moveSpeed = 5f;
8.     public float jumpForce = 5f;
9.     public float gravityScale = 2f;
10.     public Transform groundCheck;
11.     public LayerMask groundLayer;
12.  
13.     private CharacterController controller;
14.     private Vector3 motion;
15.     private bool isGrounded;
16.  
17.     void Start()
18.     {
19.         controller = GetComponent<CharacterController>();
20.     }
21.  
22.     void Update()
23.     {
24.         float horizontalInput = Input.GetAxis("Horizontal");
25.         float verticalInput = Input.GetAxis("Vertical");
26.         isGrounded = Physics.CheckSphere(groundCheck.position, 0.2f, groundLayer);
27.  
28.         if (isGrounded && motion.y < 0)
29.         {
30.             motion.y = -2f;
31.         }
32.  
33.         Vector3 moveDirection = transform.right * horizontalInput + transform.forward * verticalInput;
34.         controller.Move(moveDirection * moveSpeed * Time.deltaTime);
35.  
36.         if (Input.GetButtonDown("Jump") && isGrounded)
37.         {
38.             motion.y = Mathf.Sqrt(jumpForce * -2f * Physics.gravity.y);
39.         }
40.  
41.         motion.y += Physics.gravity.y * gravityScale * Time.deltaTime;
42.         controller.Move(motion * Time.deltaTime);
43.     }
44. }
45.  

My FirstPersonCamera script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class FirstPersonCamera : MonoBehaviour
6. {
7.     public Transform playerBody;
8.     public float mouseSensitivity = 100f;
9.  
10.     float xRotation = 0f;
11.  
12.     void Start()
13.     {
14.         Cursor.lockState = CursorLockMode.Locked;
15.     }
16.  
17.     void Update()
18.     {
19.         float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
20.         float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;
21.  
22.         xRotation -= mouseY;
23.         xRotation = Mathf.Clamp(xRotation, -90f, 90f);
24.  
25.         playerBody.Rotate(Vector3.up * mouseX);
26.  
27.         transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
28.     }
29. }
30.  

I started today by the way, I use ChatGPT for coding. If you give me a code please explain to me what it does so I can learn how to code.

 

I don't thing this is how it works. I think people here can help you with some issue but will not give you code like ChatGPT , all informations are or internet already. Also i am pretty sure it is not a "Bug".


You can start here:

How to make a Video Game - Getting Started - YouTube
Code Monkey - YouTube
Brackeys - YouTube

This one is very internesting but not rly for beginner imo.
Coding Adventure: Boids - YouTube

 

Sigh.

You're going to have to learn properly. Chat GPT is only really useful if you have some idea of what you're going already.

I watched some Brackeys tutorials and managed to fix everything, thanks a lot @MartinMa_

 

chat gpt explains every part of the code which is why I use it, its pretty good imo

 

Yes imo Chat GPT > Stack overflow but you still need to know what to ask Chat gpt
