The player moves due to the tilt of the mouse

I can't understand in any way that with the movement when the mouse is tilted down, I move backwards when I tilt up forward, as I realized this happens in the presence of gravity.
Most likely the problem is in FPSInput, since I tilted the player and deleted the MouseLook script, it didn't help
What it looks like: https://gifyu.com/image/AKcy
MouseLook:
using UnityEngine;
using System.Collections;
public class MouseLook : MonoBehaviour
{
public enum RotationAxes
{
MouseXAndY = 0,
MouseX = 1,
MouseY = 2
}
public RotationAxes axes = RotationAxes.MouseXAndY;
public float sensitivityHor = 9.0f;
public float sensitivityVert = 9.0f;
public float minimumVert = -45.0f;
public float maximumVert = 45.0f;
private float _rotationX = 0;
void Start()
{
Rigidbody body = GetComponent<Rigidbody>();
if (body != null)
body.freezeRotation = true;
}
void Update()
{
if (axes == RotationAxes.MouseX)
{
transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityHor, 0);
}
else if (axes == RotationAxes.MouseY)
{
_rotationX -= Input.GetAxis("Mouse Y") * sensitivityVert;
_rotationX = Mathf.Clamp(_rotationX, minimumVert, maximumVert);
float rotationY = transform.localEulerAngles.y;
transform.localEulerAngles = new Vector3(_rotationX, rotationY, 0);
}
else
{
_rotationX -= Input.GetAxis("Mouse Y") * sensitivityVert;
_rotationX = Mathf.Clamp(_rotationX, minimumVert, maximumVert);
float delta = Input.GetAxis("Mouse X") * sensitivityHor;
float rotationY = transform.localEulerAngles.y + delta;
transform.localEulerAngles = new Vector3(_rotationX, rotationY, 0);
}
}
}
FPSInput:
using UnityEngine;
using System.Collections;
[RequireComponent(typeof(CharacterController))]
[AddComponentMenu("Control Script/FPS Input")]
public class FPSInput : MonoBehaviour
{
public float speed = 6.0f;
public float gravity = -9.8f;
private CharacterController _charController;
void Start()
{
_charController = GetComponent<CharacterController>();
}
void Update()
{
float deltaX = Input.GetAxis("Horizontal") * speed;
float deltaZ = Input.GetAxis("Vertical") * speed;
Vector3 movement = new Vector3(deltaX, 0, deltaZ);
movement = Vector3.ClampMagnitude(movement, speed);
movement.y = gravity;
movement *= Time.deltaTime;
movement = transform.TransformDirection(movement);
_charController.Move(movement);
}
}

You most probably do NOT want the gravity to be applied in local space. This way if you look up you move forward and if you look down you move backward.
Rather you want the User input be applied in local space but the Y axis to be taken in global space.
Rather do e.g.
var deltaX = Input.GetAxis("Horizontal");
var deltaZ = Input.GetAxis("Vertical");
var movement = new Vector3(deltaX, 0, deltaZ);
// Rather first clamp to 1, then multiply by the speed
movement = Vector3.ClampMagnitude(movement, 1) * speed;
// first convert local to global space
movement = transform.TransformDirection(movement);
// then overwrite the now global Y axis with the gravity
// This at the same time also prevents User from flying upwards
// when looking up and walking forward
movement.y = gravity;
_charController.Move(movement * Time.deltaTime);

Is there anything wrong I am doing in this code, if so how do I fix it?
Entire project can be downloaded here: https://github.com/Some-T/FirstPersonController-CSharp
Project has relevant colliders and rigidbodies set up!
Someone has advised me to use shapecast, but I believe that may incorrect? I can't see how that would work as my player does not have character controller component added to it?
Overall how do I stop my first person character controller going through the wall like in the initial video specified above?
Upon further research I have discovered the following:
The answer is to use:
https://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html as a quick fix.
But definitively for flawlessness use:
https://docs.unity3d.com/ScriptReference/Rigidbody-velocity.html
As to how in C# I am not so sure, but here is a screen shot I did in bolt asset.
Currently I have movmement working with velocity but it does not work properly, not sure as to why? So overall my question now is how do I get movement working using velocity? I added a line in FirstPersonController.cs that moves the character using velocity of rb.velocity = new Vector3(HorizontalInput, 0, VerticalInput) * speed; so my only question and issue now is my player does not move in the direction the camera on my player is facing so I am not sure how to fix this specific thing overall?

In your project code is different from one that you provided here.
Try to enable rigidbody`s rotation constraint - freeze X and Z rotation, leave only Y. When you rotate your capsule collider (as it works in your project), it can "climb" on a wall.
Do the isGrounded check when you move, and lock movement, if not grounded.
Try to increase Collider.contactOffset
If above does not helps, try to use Rigidbody.velocity instead of Rigidbody.MovePosition.
You can also reduce Rigidbody.drag
In general, pretty good technique is to use NavMesh for movement - in this way, you able to explicitly lock player from movement outside of navmesh surface. But, of course, it doesn`t fit to many gameplays.
Hope, it helps.
upd
You move your player like this:
void FixedUpdate()
{
Vector3 xMovement = transform.right * speed * HorizontalInput * Time.deltaTime;
Vector3 zMovement = transform.forward * speed * VerticalInput * Time.deltaTime;
}
Note, that you not even apply it to rigidbody;
But you get your input this way:
float HorizontalInput = Input.GetAxis("Horizontal");
float VerticalInput = Input.GetAxis("Vertical");
in Update, so input just stays inside Update, and does not applied at all. You declared your variables twice, once on class top, another in Update().

Unity 5 fpscontroller weird error

I made this script for my Player object. It has to child, 1 camera and 1 model.
They problem is whenever i move my mouse the player moves down. and the cam goes up.
Script:
public GameObject cam;
public float sensitivity = 2f;
public float walk_speed = 2f;
public float run_speed = 2f;
CharacterController player_CC;
float speed;
float moveFB;
float moveLR;
float rotX;
float rotY;
bool canMove;
void Start () {
canMove = true;
player_CC = GetComponent<CharacterController>();
speed = walk_speed;
}
void Update () {
if (canMove)
{
moveFB = Input.GetAxis("Vertical") * speed;
moveLR = Input.GetAxis("Horizontal") * speed;
rotX = Input.GetAxis("Mouse X") * sensitivity;
rotY = Input.GetAxis("Mouse Y") * sensitivity;
Vector3 movement = new Vector3(moveLR, 0, moveFB);
transform.Rotate(0, rotX, 0);
cam.transform.Rotate(rotY, 0, 0);
movement = transform.rotation * movement;
player_CC.Move(movement * Time.deltaTime);
}
if (Input.GetKey(KeyCode.LeftShift))
{
speed = run_speed;
} else
{
speed = walk_speed;
}
}

movement = transform.rotation * movement;
You're multiplying your transforms rotation by your movement vector. Separate the logic.

I know what caused it. But i dont know why it did it. But i used a charachtercontroller and a rigidbody on the same object. Sorry for wasting your time :/

Unity 3D movement when no movement is desired

Very new to mono develop and Unity 3d and seem to be having issues with this code. First off, the code IS working. It does what it's supposed to, however, it also does some funky stuff that it's not supposed to. You are able to look up, down, left and right as well as walk those directions, the bad part is though for some reason my character likes to nudge the direction of the mouse when standing still. What am I missing? More efficient/less buggy way of doing this?
public class PlayerControl : MonoBehaviour {
public float WALK_SPEED = 1.3f;
public float RUN_SPEED = 4.0f;
public float STRAFE_SPEED = 5.0f;
public float ROTATION_SPEED = 300.0f;
public float JUMP_FORCE = 250.0f;
void Start()
{
}
// Update is called once per frame
void Update ()
{
float movementSpeed = WALK_SPEED;
float strafeSpeed = STRAFE_SPEED;
float rotationSpeedx = ROTATION_SPEED;
float rotationSpeedy = ROTATION_SPEED;
if (Input.GetKey(KeyCode.LeftShift))
{
movementSpeed = RUN_SPEED;
}
movementSpeed = Input.GetAxis("Vertical") * movementSpeed * Time.deltaTime;
strafeSpeed = Input.GetAxis("Horizontal") * strafeSpeed * Time.deltaTime;
rotationSpeedx = Input.GetAxis("Mouse X") * rotationSpeedx * Time.deltaTime;
rotationSpeedy = Input.GetAxis("Mouse Y") * rotationSpeedy * Time.deltaTime;
Vector3 rotate = new Vector3 (-rotationSpeedy, rotationSpeedx, 0);
transform.Translate(Vector3.forward * movementSpeed);
transform.Translate(Vector3.right * strafeSpeed);
transform.Rotate(rotate);
if (Input.GetKeyDown(KeyCode.Space) &&
transform.position.y < 30)
{
rigidbody.AddForce(Vector3.up * JUMP_FORCE);
}
}
}

Try freezing rotation constraints on rigidbody component. This may stop the nudging.

Unity/C# Weird glitch in FPS controller

i have a weird glitch, when i walk down from a corner (i dont press jump), the player will falling down with very fast speed. If i jump, then everything goes normal. (Its Quill18 FPS controller, i learn from there so thats why i dont use the built in controller instead)
using UnityEngine;
using System.Collections;
[RequireComponent (typeof(CharacterController))]
public class FirstPersonController : MonoBehaviour
{
public float movementSpeed = 5.0f;
public float mouseSensitivity = 5.0f;
public float jumpSpeed = 20.0f;
float verticalRotation = 0;
public float upDownRange = 60.0f;
float verticalVelocity = 0;
CharacterController characterController;
// Use this for initialization
void Start()
{
// Screen.lockCursor = true;
characterController = GetComponent<CharacterController>();
}
// Update is called once per frame
void Update()
{
// Rotation
float rotLeftRight = Input.GetAxis("Mouse X") * mouseSensitivity;
transform.Rotate(0, rotLeftRight, 0);
verticalRotation -= Input.GetAxis("Mouse Y") * mouseSensitivity;
verticalRotation = Mathf.Clamp(verticalRotation, -upDownRange, upDownRange);
Camera.main.transform.localRotation = Quaternion.Euler(verticalRotation, 0, 0);
// Movement
float forwardSpeed = Input.GetAxis("Vertical") * movementSpeed;
float sideSpeed = Input.GetAxis("Horizontal") * movementSpeed;
verticalVelocity += Physics.gravity.y * Time.deltaTime;
if (characterController.isGrounded && Input.GetButton("Jump"))
{
verticalVelocity = jumpSpeed;
}
Vector3 speed = new Vector3(sideSpeed, verticalVelocity, forwardSpeed ;
speed = transform.rotation * speed;
characterController.Move(speed * Time.deltaTime);
}
}

The problem is that every frame you're running this line:
verticalVelocity += Physics.gravity.y * Time.deltaTime;
Thus, you're gaining "momentum" each second, and it wont stop ever until you jump because you're "resetting" the Y velocity to a normal value. I've ran into this problem before, and it can be fixed simply by only adding the Y velocity when you're not grounded. You can use Raycast to check if you have ground, and if you dont, increase verticalVelocity by that amount.
