Unexpected Cube movement when rotating camera

I am currently making an FPS game and I have some problems with camera movement. When I add a child object to the camera, and when I rotate the camera, the child object deforms.
I followed this tutorial to get my FPS movement. https://www.youtube.com/watch?v=XAC8U9-dTZU/
Here is my camera movement script and my player movement one:
using UnityEngine;

Float is going up slower after export

i want to multiply a float. in the unity editor everything is ok too, in the build it is going up slower all of a sudden.
i tried reimporting all assets and restart my pc but that does not help either.
I tried to build it again but that did not help.
I do not know what to do now, does anyone know how to fix this problem?

What you experience is the typical frame-rate dependent code.
Every frame you do
Stamina += fillStamina;
and
Health += fillHealth;
However, what if on one device you have 60 frames per second, on another weaker device only 30?
On the weaker device it will take twice as long to raise the value.
Therefore you should use Time.deltaTime which is the time passed since the last frame was rendered.
By multiplying
X * Time.deltaTime
you convert a value X from value per frame into a value per second which is now independent of the capacity of the device and the frame-rate. Across all devices it will now always take the same effective time in seconds.
You will of course have to tweak your values but in general you would do e.g.
Stamina += fillStaminaPerSecond * Time.deltaTime;
and accordingly
Health += fillHealthPerSecond * Time.deltaTime;
And accordingly also for the continous usages
UseStamina(10 * Time.deltaTime);
and
UseStamina(2f * Time.deltaTime);
as said you might have to adjust the values since now they are more or less decided by 60 (whatever the frame-rate is).
However, for the single event calls for the jump you do not want/need the Time.deltaTime since these are no continous calls.
Btw instead of using GetComponent over and over again rather do it once in Awake or Start and store the reference in a field and later reuse it!
And instead of
[Header("")]
you should probably rather use
[Space]

I use a script for rotation of the camera with the mouse and I want to transform it for the touch . I want my camera to rotate just when I touch the screen . The game has a first player controller . Please help me to make it for touchscreen

Get the first Touch, then use touch.deltaPosition to find how much the touch has moved since the last update. Then, you can scale with screen size and sensitivity.
void Update()
{
if(Input.touchCount > 0) {
Touch touch = Input.GetTouch(0);
float turnAngleChange = (touch.deltaPosition.x / Screen.width) * sensitivityX;
float pitchAngleChange = (touch.deltaPosition.y / Screen.height) * sensitivityY;
// Handle any pitch rotation
if (axes == RotationAxes.MouseXAndY || axes == RotationAxes.MouseY) {
rotationY = Mathf.Clamp(rotationY+pitchAngleChange, minimumY, maximumY);
transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0f));
}
// Handle any turn rotation
if (axes == RotationAxes.MouseXAndY || axes == RotationAxes.MouseX) {
transform.Rotate(0f, turnAngleChange , 0f);
}
}
}
As a sidenote, it can be confusing to call pitch rotations rotationY even though they are actually rotations along the x axis, and vice versa.

Unity 2018 C# - Fbx Running animation scaling with Input?

I have figured out how to get fbx animations working in Unity for my character in my adventure game, but now I wish to have my character's running animation move with its speed of motion being in relation to the input of the control stick on an xbox controller.
In addition, when I add a walking animation in the future I wish to make a threshold for the control stick input so that the character walks when there is minimal input from the control stick and running when there is more input from the control stick. Any advice?

Smoothing Vector3.normalized?

I have created a player inside of Unity 3D with a Character Controller, I got him all configured to walk, look around and such. So when using a normal vector3 the player starts of smoothly until it's at his max speed. When I don't normalize it, you can walk faster by pressing W and D/A at the same time, you go about 50% faster than normal. But when I normalize it, the player is immediately at it's max speed. Which looks very weird.
How would I do it so the player starts smoothed out before it's at it max speed?
Here's my full script, incase you need it:
using UnityEngine;
using System.Collections;
public class FirstPersonController : MonoBehaviour {
CharacterController cc;
public float baseSpeed = 3.0f;
public float mouseSensitivity = 1.0f;
public bool inverted = false;
public bool gravityOn = true;
public bool lockMouse = true;
float mouseRotX = 0,
mouseRotY = 0;
float curSpeed = 3.0f;
float invertion = 1.0f;
float gravitySpeed = 0;
string h = "Horizontal";
string v = "Vertical";
void Start () {
cc = gameObject.GetComponent<CharacterController>();
if (lockMouse && Debug.isDebugBuild)
Screen.lockCursor = true;
if (!Debug.isDebugBuild)
Screen.lockCursor = true;
}
void FixedUpdate () {
curSpeed = baseSpeed;
if (inverted)
invertion = -1.0f;
else
invertion = 1.0f;
mouseRotX = Input.GetAxis("Mouse X") * mouseSensitivity;
mouseRotY -= invertion * Input.GetAxis("Mouse Y") * mouseSensitivity;;
mouseRotY = Mathf.Clamp(mouseRotY, -90.0f, 90.0f);
float forwardMovement = Input.GetAxis(v);
float strafeMovement = Input.GetAxis(h);
Vector3 speed = new Vector3(strafeMovement, 0, forwardMovement);
speed = transform.rotation * speed;
Debug.Log(speed.normalized);
//Applying Gravity
if (cc.isGrounded)
{
gravitySpeed = 0.0f;
}
else if (gravityOn)
{
if (gravitySpeed >= 20.0f)
{
gravitySpeed = 20.0f;
}
if (cc.isGrounded == false)
{
gravitySpeed += Physics.gravity.y * Time.deltaTime;
}
cc.Move(new Vector3(0, gravitySpeed, 0) * Time.deltaTime);
}
//Applying movement and rotation.
cc.Move(speed.normalized * curSpeed * Time.deltaTime);
transform.Rotate(0, mouseRotX, 0);
Camera.main.transform.localRotation = Quaternion.Euler(mouseRotY, 0 ,0);
}
}

The feature you want to get is uniformly accelerated motion.
You need something like this:
Vector3 _speed = Vector3.zero;
const float KDrag = 0.25f;
void FixedUpdate ()
{
float forwardMovement = Input.GetAxis(v);
float strafeMovement = Input.GetAxis(h);
Vector3 acceleration = cc.transform.right * strafeMovement + cc.transform.forward * forwardMovement;
_speed += acceleration * Time.fixedDeltaTime;
_speed -= _speed * KDrag * Time.fixedDeltaTime;
cc.Move( _speed * Time.fixedDeltaTime );
}
