First-Person Controller spazzing out.

Unity Engine
1

I’m a bit new to Unity. My FPS Controller sometimes starts rotating randomly out of control when it moves or crouches, only stopping when I face a certain direction. I’ve tried looking into the RigidBody component to see if one of the axis rotations besides Y were unfreezed. I’ve also checked if the controller’s children had colliders and despite the fact that there were none, my controller still went out of control. I also considered looking into three C# scripts:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Player_Controller_01 : MonoBehaviour
{
Player_Input_01 playerInput_01;
Rigidbody mybody;
public float speed = 2.5f;
public float walkSpeed;
public float runSpeed;
public float crouchSpeed;

void Start()
{
playerInput_01 = GetComponent<Player_Input_01>();
mybody = GetComponent();

Cursor.lockState = CursorLockMode.Locked;
}
// Update is called once per frame
void Update()
{
float horizontal = Input.GetAxis(“Horizontal”);
float vertical = Input.GetAxis(“Vertical”);
{
Vector3 moveDirection = new Vector3(horizontal, 0f, vertical) * speed * Time.deltaTime;
transform.Translate(moveDirection);
if (Input.GetKeyDown(playerInput_01.crouchKey))
{
speed = crouchSpeed;
}
if (Input.GetKeyUp(playerInput_01.crouchKey))
{
speed = walkSpeed;
}
if(Input.GetKeyDown(playerInput_01.sprintKey))
{
speed = runSpeed;
}
if(Input.GetKeyUp(playerInput_01.sprintKey))
{
speed = walkSpeed;
}
}
}
void FixedUpdate ()
{

}
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Player_fpsCam_01 : MonoBehaviour
{
Vector2 mouseLook;
public float sensitivity;
GameObject character;
// Start is called before the first frame update
void Start()
{
character = this.transform.parent.gameObject;
}
// Update is called once per frame
void Update()
{
float horizontal = Input.GetAxis(“Mouse X”);
float vertical = Input.GetAxis(“Mouse Y”);
Vector2 look = new Vector2(horizontal, vertical);
mouseLook += look * sensitivity;
mouseLook.y = Mathf.Clamp(mouseLook.y, -80f, 80);
transform.localRotation = Quaternion.AngleAxis(-mouseLook.y, Vector3.right);
character.transform.localRotation = Quaternion.AngleAxis(mouseLook.x, character.transform.up);
}
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Player_Crouch : MonoBehaviour
{
CapsuleCollider playerCol;
float originalHeight;
public float reducedHeight;
// Start is called before the first frame update
void Start()
{
playerCol = GetComponent();
originalHeight = playerCol.height;
}
// Update is called once per frame
void Update()
{
//Crouch;
if (Input.GetKeyDown(KeyCode.LeftControl))
Crouch();
else if (Input.GetKeyUp(KeyCode.LeftControl))
GoUp();
}
//Method to reduce height;
void Crouch()
{
playerCol.height = reducedHeight;
}
//Method to reset height;
void GoUp()
{
playerCol.height = originalHeight;
}
}

Here is a link to the video demonstrating this issue, showing both the scene and game view: https://www.dropbox.com/s/9434o31spv8to2l/Screen Recording (6-6-2020 7-07-38 PM).wmv?dl=0
Thank you.

One thing to check - are you sure that there is only one rigidbody in the whole character chain? Your video clearly show the collider rotating, so either:

  1. It’s not parented to a locked rigidbody (I’m sure it is, unless you have some joints in there)

  2. The rigidbody is not locked in rotations (you say you have checked this).

  3. There is more than one rigidbody in the chain (seems possible).

After that, I have no ideas - perhaps someone else has a better suggestion? Can you replicate this with a single gameobject with one rigidbody and one colldier on it?
