Problems with FPS camera.

Unity Engine
1

Hello, I am a noob at coding in c# and after a day of trying to create my own FPS camera looking script, I finally came up with a script that doesn’t give any errors… but it doesn’t work either.

When I run my game, the camera appears to be rotating a tiny bit when I move my mouse but it quickly returns back to zero, giving a sort of jittery effect.

Here is the code I’m trying to run:

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

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

public class PlayerLook : MonoBehaviour
{
float mouseSensitivity = 10f;

public Transform PlayerBody;
public Transform Cam;

// Update is called once per frame
void Update()
{
float mouseX = Input.GetAxis(“Mouse X”) * mouseSensitivity * Time.deltaTime;
float mouseY = Input.GetAxis(“Mouse Y”) * mouseSensitivity * Time.deltaTime;

mouseX = Mathf.Clamp(mouseX, -90f, 90f);

PlayerBody.transform.localEulerAngles = new Vector3(0, mouseY, 0);
Cam.transform.localEulerAngles = new Vector3(-mouseX, mouseY, 0);

}
}

Can anyone help?

If you post a code snippet, ALWAYS USE CODE TAGS:

How to report your problem productively in the Unity3D forums:

How to understand compiler and other errors and even fix them yourself:

For camera stuff you may wish to consider installing Cinemachine and using their stuff.

If you want to debug the above, to help gain more insight into your problem, I recommend liberally sprinkling Debug.Log() statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

  • is this code even running? which parts are running? how often does it run?
  • what are the values of the variables involved? Are they initialized?

Knowing this information will help you reason about the behavior you are seeing.
