Creating a Unity UI slider logic to manipulate the Fog discretely, where the fog will be set active after certain duration and increment with slider

So, I created a game, where I need to simulate fog. The fog is supposed to be displayed when rain >= 50 mm. I implemented the logic as follows, please refer the part where I commented as //What needs to be added here so as the Fog will start to be displayed at rain >= 50 on "_slider" slider
P.s., the block:
public void _FogIntensity(float newHeightDensity)
{
heightDensity = newHeightDensity;
}
is used in the file "GlobalFog.cs" and function "public void SliderLogic()" , given below: to control the Fog Intensity with respect to slider, I need to activate the slider when rain count >=50 mm; else, not.

Converting pinch to zoom to new InputSystem

I am trying to convert pinch to zoom from old input to new Input system using EnhancedTouch.Touch. Unfortunately I am clueless as to how to move forward from here? I am getting error as Operator '==' cannot be applied to operands of type 'TouchPhase' and 'TouchPhase'. How do I fix this?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.InputSystem.EnhancedTouch;
using Touch = UnityEngine.InputSystem.EnhancedTouch.Touch;
public class ZoomTouch : MonoBehaviour {
public Camera camera;
float touchDist = 0;
float lastDist = 0;
public void Update () {
if (Input.touchCount == 2) {
Touch touch1 = Touch.activeFingers[0].currentTouch;
Touch touch2 = Touch.activeFingers[0].currentTouch;
if (touch1.phase == TouchPhase.Began && touch2.phase == TouchPhase.Began) {
lastDist = Vector2.Distance (touch1.position, touch2.position);
}
if (touch1.phase == TouchPhase.Moved && touch2.phase == TouchPhase.Moved) {
float newDist = Vector2.Distance (touch1.position, touch2.position);
touchDist = lastDist - newDist;
lastDist = newDist;
camera.fieldOfView += touchDist * 0.1f;
}
}
}
}

I hope this code works. However, I did not have a touch device to test it. This simple code works, takes the distance between the present and the past, and zooms in on their delta.
public float lastDistance;
public float distance;
void Update()
{
if (Input.touchCount < 2) return;
var touch1 = Input.GetTouch(0);
var touch2 = Input.GetTouch(1);
distance = Vector2.Distance(touch1.position, touch1.position);
if (Mathf.Abs(lastDistance-distance) >= 10) lastDistance = distance; // for avoiding sharp zooms on first touch
Camera.main.fieldOfView += distance-lastDistance * 0.1f;
lastDistance = distance;
}

Instantiating Custom Object in Unity MonoBehaviour Scripts

I'm trying to programm my own little game in Unity, I'm not new to programming but new to Unity and C#. The problem is that I wrote my own classes to handle the game map and I am trying to connect these classes to the MonoBehaviour Scripts in Unity.
I have a script called InputManager, which is supposed to handle the input via mouse and keyboard etc. and in this script I want to create an object of the class MapManager which has access to my tiles and stuff. The problem I'm getting is that I can't seem to create an instance of MapManager in InputManager, not with the common new MapManager() anyway. When I use this a NullPointer of some sort is created, I guess?
I do not get a compiling error but an error once the game is launched which is:
NullReferenceException: Object reference not set to an instance of an object
InputManager.Update () (at Assets/Scripts/InputManager.cs:55)
Thank you for your help!
!UPDATE!:
I tried using a workaround so that it does not matter if Start() or Update() is called first, meaning that I just instantiate MapManager in the first Update() call. However, when I run the program the error is still the same. My conclusion is that somehow my constructor is not working or the Monobehaviour script somehow does not allow using the standard constructor... Any ideas?
Here is my code:

How can I find the center position of two or more objects?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveCameraBehind : MonoBehaviour
{
public GameObject camera;
public List<GameObject> targets = new List<GameObject>();
public float cameraDistance = 10.0f;
public bool behindMultipleTargets = false;
public string cameraWarningMsgs = "";
public string targetsWarningMsgs = "";
// Use this for initialization
void Start()
{
if (camera == null)
{
var cam = GetComponent<Camera>();
if (cam != null)
{
cameraWarningMsgs = "Gettig camera component.";
camera = transform.gameObject;
}
else
{
cameraWarningMsgs = "Creating a new camera component.";
GameObject NewCam = Instantiate(new GameObject(), transform);
NewCam.name = "New Camera";
NewCam.AddComponent<Camera>();
camera = NewCam;
}
}
if(targets.Count == 0)
{
targetsWarningMsgs = "No targets found.";
}
}
void FixedUpdate()
{
if (targets.Count > 0)
{
MoveCameraToPosition();
}
}
public void MoveCameraToPosition()
{
if (targets.Count > 1 && behindMultipleTargets == true)
{
var center = CalculateCenter();
transform.position = new Vector3(center.x, center.y + 2, center.z + cameraDistance);
}
if (behindMultipleTargets == false)
{
Vector3 center = targets[0].transform.position - targets[0].transform.forward * cameraDistance;
transform.position = new Vector3(center.x, center.y + 2, center.z);
}
}
private Vector3 CalculateCenter()
{
Vector3 center = new Vector3();
var totalX = 0f;
var totalY = 0f;
foreach (var target in targets)
{
totalX += target.transform.position.x;
totalY += target.transform.position.y;
}
var centerX = totalX / targets.Count;
var centerY = totalY / targets.Count;
center = new Vector3(centerX, centerY);
return center;
}
}
The CalculateCenter function make the targets(objects) to change positions and vanish away far away. Even if there is only one single target.
What I want to do is if there is one object for example one 3d cube position the camera behind the cube. And if there are more cubes for example two or ten and the camera is somewhere else calculate the middle position behind the targets and position the camera in the middle behind them.
To show what I mean in this example the view(like a camera) is behind the two soldiers in the middle position between them from behind.
But what if there are 5 soldiers how can I find the middle position and then position the camera behind them like this example in the screenshot ?
This is my old script version was working fine but only for 1 or 2 targets. But if there are 5 targets(soldiers) how can I position the camera behind them in the middle ? Like in the screenshot example.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveCameraBehind : MonoBehaviour
{
public GameObject camera;
public List<GameObject> targets = new List<GameObject>();
public float cameraDistance = 10.0f;

public string warningMsgs = "";
// Use this for initialization
void Start()
{
if (camera == null)
{
var cam = GetComponent<Camera>();
if (cam != null)
{
warningMsgs = "Gettig Camera omponent.";
camera = transform.gameObject;
}
else
{
warningMsgs = "Creating a new camera component.";
GameObject NewCam = Instantiate(new GameObject(), transform);
NewCam.name = "New Camera";
NewCam.AddComponent<Camera>();
camera = NewCam;
}
}
camera.transform.Rotate(0, 180, 0);
}
void FixedUpdate()
{
if (targets.Count > 0)
{
MoveCameraToPosition();
}
}
public void MoveCameraToPosition()
{
if (targets.Count == 2 && behindTwoTargets == true)
{
Vector3 center = ((targets[0].transform.position - targets[1].transform.position) / 2.0f) + targets[1].transform.position;
camera.transform.position = new Vector3(center.x, center.y + 2, center.z + cameraDistance);
}
if (behindTwoTargets == false)
{
Vector3 center = targets[0].transform.position - targets[0].transform.forward * cameraDistance;
camera.transform.position = new Vector3(center.x, center.y + 2, center.z);
}
}
}
This is my last version of my working code still using the CalculateCenter function :

}

}
else
{
foreach(GameObject vector in targets)
{

}
}
}

if (targetsRandomRot == true)
{

}
}
}
public void MoveCameraToPosition()
{

camera.transform.position = center;
if (behindFront == false)
{

}
else
{

}
}
private Vector3 CalculateCenter()
{
Vector3 center = new Vector3();
var x = targets[0].transform.position.x;
var y = targets[0].transform.position.y;
var z = targets[0].transform.position.z;
if (multipleTargets == true)
{
for (int i = 1; i < targets.Count; i++)
{
x += targets[i].transform.position.x;
y += targets[i].transform.position.y;

}
}
else

}
}
x = x / targets.Count;
y = y / targets.Count;
z = z / targets.Count;
if (behindFront == false)
{
center = new Vector3(x, y + cameraHeight, z + cameraDistance);
}
else
{
center = new Vector3(x, y + cameraHeight, z - cameraDistance);
}
return center;
}
private void RotateTargetsRandom()
{
timer += Time.deltaTime;
if (timer > rotateTime)
{ // timer resets at 2, allowing .5 s to do the rotating
qTo = Quaternion.Euler(new Vector3(0.0f, Random.Range(-180.0f, 180.0f), 0.0f));
timer = 0.0f;
}
foreach (var target in targets)
{
target.transform.rotation = Quaternion.Slerp(target.transform.rotation, qTo, Time.deltaTime * speed);
}
}
}
And now I want to add and use the bool flag changeRandomTarget :
But not sure how to do it :
if(changeRandomTarget == true)
{
for (int i = 1; i < targets.Count; i++)
{
x += targets[i].transform.position.x;
y += targets[i].transform.position.y;
z += targets[i].transform.position.z;
}
}
I want that each X seconds it will pick a random center and change the camera position according to it. For example the first item in the targets List the last item and all the items so each X seconds the center will be once behind targets[0] or targets1 or targets[i]
Not sure how to do it with my code or with derHugo solution.

Surely you just find the average
so
if (mobcount > 1)
{
var x=mob[0].position.x;
var y=mob[0].position.y;
var z=mob[0].position.z;
for(int i=1; i<mobcount; i++)
{
x += mob[i].position.x;
y += mob[i].position.y;
z += mob[i].position.z;
}
x = x / mobcount;
y = y / mobcount;
z = z / mobcount;
}
therefore the camera should look at the position x,y,z.. and perhaps set the distance to be a fixed distance behind the nearest mob...

Actually you don't even need to do it component wise:
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
...
private static Vector3 Average(IReadOnlyCollection<Vector3> vectors)
{
if(vectors == null) return Vector3.zero;
switch (vectors.Count)
{
case 0:
return Vector3.zero;
case 1:
return vectors.First();
default:
var average = Vector3.zero;
foreach(var vector in vectors)
{
average += vector;
}
return average / vectors.Count;
}
}
Or directly using Linq aggregate
private static Vector3 Average(IReadOnlyCollection<Vector3> vectors)
{
if(vectors == null) return Vector3.zero;
switch (vectors.Count)
{
case 0:
return Vector3.zero;
case 1:
return vectors.First();
default:
var average = vectors.Aggregate(Vector3.zero, (current, vector) => current + vector);
return average / vectors.Count;
}
}

How can I make that the object will scale automatic up/down nonstop?

Now I'm using the F key to make it scale up or down.
But I want to add another method for example AutoScaling that when calling it in Update it will scale up first once finished scaling up it will scale down and then up again and so no nonstop.
The Scaling script :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Scaling : UnityEngine.MonoBehaviour
{
public GameObject objectToScale;
public GameObject lookAtTarget;
public float duration = 1f;
public Vector3 minSize;
public Vector3 maxSize;
public bool scaleUp = false;
public Coroutine scaleCoroutine;
public bool scalingHasFinished = false;
public void Inits()
{
scalingHasFinished = false;
objectToScale.transform.localScale = minSize;
}
public IEnumerator scaleOverTime(GameObject targetObj, Vector3 toScale, float duration, Camera objectToScaleCamera)
{
float counter = 0;
Vector3 startScaleSize = targetObj.transform.localScale;
while (counter < duration)
{
counter += Time.deltaTime;
targetObj.transform.localScale = Vector3.Lerp(startScaleSize, toScale, counter / duration);
if (scaleUp)
{
var lookPos = lookAtTarget.transform.position - objectToScale.transform.position;
lookPos.y = 0;
var rotation = Quaternion.LookRotation(lookPos);
objectToScale.transform.rotation = Quaternion.Slerp(objectToScale.transform.rotation, rotation, counter / duration);
}
else
{
var lookPos = lookAtTarget.transform.position - objectToScale.transform.position;
lookPos.y = 0;
var rotation = Quaternion.LookRotation(objectToScaleCamera.transform.forward);//SwitchCameras.GetCurrentCamera().transform.forward);//Camera.main.transform.forward);
objectToScale.transform.rotation = Quaternion.Slerp(objectToScale.transform.rotation, rotation, counter / duration);
}
yield return null;
}
scalingHasFinished = true;
}
public IEnumerator scaleOverTime(GameObject targetObj, Vector3 toScale, float duration, float rotationSpeed)
{
float counter = 0;
Vector3 startScaleSize = targetObj.transform.localScale;
while (counter < duration)
{
counter += Time.deltaTime;
targetObj.transform.localScale = Vector3.Lerp(startScaleSize, toScale, counter / duration);
targetObj.transform.Rotate(Vector3.up * rotationSpeed * Time.deltaTime, Space.Self);
yield return null;
}
}
}
And the script that use the scaling :
using System.Collections;

And in third script I want to call a method that will be in the ObjectsManipulation script maybe the same method Scaling maybe he will get a bool and if the bool is true make it scaling up/down automatic if it's not true make it use a key.
This is the script for testing the Scaling :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class ScalingTest : MonoBehaviour
{
ObjectsManipulation om;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
om.Scaling();
}
}
For example in the Update maybe to do : om.Scaling(false); for using the F key and om.Scaling(true); for automatic.
Update of what I have tried :
using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using UnityEditor;
using UnityEngine;
public class ConversationTrigger : MonoBehaviour
{
public List<Conversation> conversations = new List<Conversation>();
[HideInInspector]
public int dialogueIndex;
[HideInInspector]
public int conversationIndex;
private bool triggered = false;
private bool activateButton = false;
private DialogueManager dialoguemanager;
private bool startDialogue = false;
private void Start()
{
dialogueIndex = 0;
dialoguemanager = FindObjectOfType<DialogueManager>();
}
public IEnumerator PlayConversation(int index)
{
this.conversationIndex = index;
if (conversations.Count > 0 &&
conversations[index].Dialogues.Count > 0)
{
for (int i = 0; i < conversations[index].Dialogues.Count; i++)
{
if (triggered == false)
{
if (dialoguemanager != null)
{
dialoguemanager.StartDialogue(conversations[index].Dialogues[i]);
}
while (DialogueManager.dialogueEnded == false)
{
yield return null;
}
}
}
}
}
public void SaveConversations()
{
string jsonTransform = JsonHelper.ToJson(conversations.ToArray(), true);
File.WriteAllText(#"d:\json.txt", jsonTransform);
}
public void LoadConversations()
{
string jsonTransform = File.ReadAllText(#"d:\json.txt");
conversations.Clear();
conversations.AddRange(JsonHelper.FromJson<Conversation>(jsonTransform));
}
}
And using it like this :
StartCoroutine(conversationTrigger.PlayConversation(0));
Where conversationTrigger is public ConversationTrigger conversationTrigger;
But it's not working good at all. It's starting the conversation index 0 but then play only the first dialogue sentences twice and then never continue to the next dialogue there are two dialogues in this case. And then it stop.
It should play all the dialogues of the current conversation.
Something in the PlayConversation method is wrong.

I'm sorry to say your post is long and contains many redundant codes, so I haven't carefully read it, this is a simple reference about making a zoom animation by script.
float minScale; // Minimum scale value
float maxScale; // Maximum scale value
Transform target; // Target to scale
void Update()
{
float scale = Mathf.PingPong(Time.time, maxScale - minScale) + minScale;
target.localScale = new Vector3(scale, scale, scale);
}
