I can look on the y axis only but not x

so i was doing some scripting for a game(my first time using unity) and i used some code and it did not work so i messed with it so now i have a peaice of code that can only look up and down but not left to right here is my code


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

public class MouseLookAround : MonoBehaviour
{

public float mouseSensitivity = 150f;

public Transform playerBody;

float xRotation = 0f;


// Start is called before the first frame update
void Start()
{

}

// 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);
}
}

 

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

To track down a weird behavior like this, Debug.Log() is always your friend.

That way you can see where the part that is supposed to turn you isn't getting through.

In fact, 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.

 

how do you mean this do i like put the line number in the parenthisis then i just put it in my script for unity

 

Just helped someone else with a rotation issue. It looks like you are only updating one axis for your camera. Also, I am assuming when you say "y axis", you are referring to up/down rotation?

Rotations are different than postitions, so keep in mind that when referring to axis of rotations, make sure you mention the correct one to avoid confusion. I was initially confused because the X axis for an euler rotation angle is the up/down rotation, not the Y axis.

Anyways, you need to create a yRotation variable and assign it accordingly.
Here is a modified version of your souce:

Code (CSharp):

1. float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
2. float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;
3.  
4. // Up/down rotation.
5. xRotation -= mouseY;
6. xRotation = Mathf.Clamp(xRotation, -90f, 90f);
7.  
8. // Left/right rotation.
9. yRotation += mouseX;
10.  
11. transform.localRotation = Quaternion.Euler(xRotation, yRotation, 0f);

Again, make sure to create a yRotation variable at the top of your source file.
