X axis buggy in mouse look script, but y axis fine? - c#

In Unity I used this little script to move the mouse around like in an FPS, but looking from side to side is extremely buggy and it will only move a bit in either direction before defaulting to looking straight forward. Looking up and down works perfectly, and I have a clamping script to only look up 90 degrees or down 90 degrees. For some reason, before adding in the code for looking up and down, it worked perfectly, but the two together makes it all buggy. Any help?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MouseLook : MonoBehaviour
{
public float mouseSpeed = 100f;
public Transform playerBody;
float xRotation = 0f;
void Start()
{
Cursor.lockState = CursorLockMode.Locked;
}
void Update()
{
float mouseX = Input.GetAxis("Mouse X") * mouseSpeed * Time.deltaTime;
float mouseY = Input.GetAxis("Mouse Y") * mouseSpeed * Time.deltaTime;
xRotation -= mouseY;
xRotation = Mathf.Clamp(xRotation, -90f, 90f);
transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
playerBody.Rotate(Vector3.up * mouseX);
}
}

you may have to experiment but this line looks like it doesnt belong
xRotation -= mouseY;

This is a problem i get too when i first make fps fames and i think i fix it by adding the code to FixedUpdate(). Alternativelly you can try and switching the playerBody.Rotate() with the transform.localRotation

Wierd camera snapping

I was testing my game, and then when I ran the code the camera started doing weird snapping that made camera movement difficult. Here is the script:
public class CameraMovement : MonoBehaviour
{
public float sensX;
public float sensY;
public bool killSwitch;
public Transform orientation;
float yRotation;
float xRotation;
void Start()
{
Cursor.lockState = CursorLockMode.Locked;
}
private void Update()
{
float mouseX = Input.GetAxisRaw("Mouse X") * Time.deltaTime * sensX;
float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * sensY;
yRotation += mouseX;
xRotation -= mouseY;
xRotation = Mathf.Clamp(xRotation, -90f, 90f);
transform.rotation = Quaternion.Euler(xRotation, yRotation, 0);
orientation.rotation = Quaternion.Euler(0, yRotation, 0);
}
}
I tried reloading but that didn't work. I'm really confused because it was working a minute ago.
If you've setup your Input Manager settings incorrectly, you'll likely see a 'Sensitivity' default of 1000. Which would cause your mouse to be returns hugely large numbers when moving around.
Instead, try a sensitivity of 1 in the Input Manager, and then fine tune it in your Component through the Inspector. The CameraMovement component sensX and sensY were set to 10 in the animation below.

Interpolate Between Quaternion.Slerp for rotate around player & Vector3.Lerp to keerp camera chasing the player

im having an issue with the rotation of the camera around player getting too much damping. i do try to manipulate those speed value but it doesnt work at all. i think thats need something combination between slerp and lerp together, and i just dont know how. Btw im trying to create a third person game and the camera scripts make me stuck, and also i try to create my own scripts rather than using cinemachine. Really hope u guys can help me out.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Camera : MonoBehaviour
{
public float MouseX, MouseY;
public Transform Player;
public float SmoothTime;
public float DefaultZoom = 5f;
public float ZoomSpeed;
Vector3 NewPosition;
Quaternion NewRotation;
//----------------------------------------------------------------------------------------------------
void Start()
{
Cursor.lockState = CursorLockMode.Locked;
Player = GameObject.Find("Player").transform;
}
//----------------------------------------------------------------------------------------------------
void Update()
{
MouseX += Input.GetAxis("Mouse X") * 100f * Time.deltaTime;
MouseY -= Input.GetAxis("Mouse Y") * 100f * Time.deltaTime;
MouseY = Mathf.Clamp(MouseY, -75, 75);
DefaultZoom += Input.GetAxis("Mouse ScrollWheel") * 100f * Time.deltaTime;
DefaultZoom = Mathf.Clamp(DefaultZoom, 3f, 9f);
DefaultZoom = Mathf.Lerp(Vector3.Distance(transform.position, Player.position), DefaultZoom, ZoomSpeed * Time.deltaTime);
}
void LateUpdate()
{
NewRotation = Quaternion.Euler(MouseY, MouseX, 0f);
transform.rotation = Quaternion.Slerp(transform.rotation, NewRotation, Time.deltaTime * SmoothTime);
NewPosition = Player.position - (transform.forward * DefaultZoom);
transform.position = Vector3.Lerp(transform.position, NewPosition, Time.deltaTime * SmoothTime);
}
}
You are using Lerp wrong, both for rotation and position. Lerp isn't actually intended for smoothing, but is used for that purpose never the less, since it is very quick to program.
To fix your problem quickly (tho at the cost of being frame rate dependent), simply remove the Time.deltaTime and make sure that the smooth variable is kept between 0 and 1. The underlying reason is that Time.deltaTime is jumpy (or jittery) by nature and it passes that property directly to Lerp.

Not being able to look sideways in unity

I want to make a fps game. To create first person viewer I followed this tutorial youtube
I followed everything that he told to do and I could successfully look up or down but could not look sideways.
Here`s the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class mouselook : MonoBehaviour
{
float mousesenitivevity = 100f;
public Transform player_eyes;
float xRotation = 0f;
// Start is called before the first frame update
void Start()
{
Cursor.lockState = CursorLockMode.Locked;
}
// Update is called once per frame
void Update()
{
float mouseX = Input.GetAxis("Mouse X") * mousesenitivevity * Time.deltaTime;
float mouseY = Input.GetAxis("Mouse Y") * mousesenitivevity * Time.deltaTime;
xRotation -= mouseY;
xRotation = Mathf.Clamp(xRotation, -90f, 90f);
transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
player_eyes.Rotate(Vector3.up * mouseX);
}
}
I really do not know where the error is occurring but here are a few things I noticed:
If you comment out the line transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f); then the player can look sideways but not up and down and if you uncomment it the player can look up and down but not sideways.
Here is the unity editor screenshots for more details:

Solved, I put the script on the player instead of the camera by mistake.

How do I fix my camera's xRotation's Clamping?

I made a first person camera using parts of Brackeys Guide, I have camera moving on both the axis but the line for the xRotation clamp doesn't work when I run the game. How can I fix this?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MouseLook : MonoBehaviour
{
public float mouseSensitivity = 200f;
public Transform playerBody;
public Transform cam;
private float xRotation = 0f;
// Start is called before the first frame update
void Start()
{
Cursor.lockState = CursorLockMode.Locked; // stops you from click out off the sceen
}
// Update is called once per frame
void Update()
{
float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime; // mouse imput
float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime; // mouse imput
xRotation = mouseY;
xRotation = Mathf.Clamp(xRotation, -80f, 73f); // stops you from breaking your neck
Quaternion localRotation = Quaternion.Euler(xRotation, 0f, 0f); // left and right movement
playerBody.Rotate(Vector3.up * mouseX); // left and right movement
cam.Rotate(Vector3.left * mouseY); // up and down movement
}
Setting new specific variables like roty and rotx, and clamping them individually.
It may be that the Vector3 vector has no value, if a value is generated, it can be
private Vector3 m_Dir
void Update () {
this.m_Dir = new Vector3 (localRotation, Vector3.up * mouseX,
tVector3.left * mouseY);
playerBody.Rotate(m_Dir);
cam.Rotate(m_Dir);
}
There are two main problems in the Update method:
xRotation = mouseY is not correct, since mouseY represents the delta angle you want to rotate in this frame, while xRotation represents the current angle at which the camera is rotated. You have to do a sum to get the next pitch of the camera, so xRotation += mouseY.
The quaternion localRotation is created but not actually used in the rotating logic, you still rotate the camera with cam.Rotate(Vector3.left * mouseY). Replace it with cam.localRotation = localRotation.
The final code should look like this:
float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;
// note: you shouldn't hardcode the min and max values,
// use some values that you can change in the inspector
xRotation = Mathf.Clamp(xRotation + mouseY, -80f, 73f);
cam.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
playerBody.Rotate(Vector3.up * mouseX);

Adding recoil to an FPS game using C# (Unity)

Ive been trying to add recoil to my fps game (Used Brackeys tutorials for the base), but the camera looking script is causing the rotation to be set each frame. I cant figure out how to change the camera rotation without the script resetting it
Code for the looking script is attatched below
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MouseLook : MonoBehaviour
{
public float mouseSensitivity = 1500f;
public Transform playerBody;
float xRotation = 0f;
// Start is called before the first frame update
void Start()
{
Cursor.lockState = CursorLockMode.Locked;
}
// 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;
xRotation -= mouseY;
xRotation = Mathf.Clamp(xRotation, -90f, 90f);
transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
playerBody.Rotate(Vector3.up * mouseX);
}
}
To change the camera rotation without the script resetting it I would use an if statement to check if a different rotation should be applied ex:
bool canLook = true;
if(canLook == false) {
//apply your desired rotation
}
else
{
//run your looking code
}
//When you want to apply your rotation set canLook to false
//And when you want to return to the camera movement set canLook to true
