Unity PUN 2 shooting not syncing

I wanted to add multiplayer to my game but i quickly faced many many problems, i cant find any clear solution online. i made a weapon script where the player can shoot and reload.
problems:
when i shoot, on 1 screen both players shoot, but at the other screen nothing happens
when i swap weapons, on 1 screen both players swap weapons, on the second screen nothing happens
note: im still a complete beginner so go easy on me please :)) thanks!
weapon script:
using System.Collections;
using System.Collections.Generic;

using Photon.Pun;

if(Input.GetAxis("Mouse ScrollWheel") > 0f)
{
if(selectedWeapon >= transform.childCount - 1)
{

foreach (Transform weapon in transform)
{
if(i == selectedWeapon)
{
weapon.gameObject.SetActive(true);
}
else
{
weapon.gameObject.SetActive(false);
}
i++;
}
}
}
i tried adding
if(view.IsMine == true)
{
Debug.Log("true");
}
else
{
Debug.Log("false");
}
but nothing happened and i couldnt shoot anymore. thanks for reading

The problem is you don't sync anything in your game. This means the other computer can't know what it has to do.
Whenever you want to sync something you have to call an RPC function.
Maybe watch some tutorials about how to do this properly and how to set up a simple multiplayer lobby.
EDIT:
What the other comments above mentioned with .IsMine is true, but you're doing it wrong. You have to call this in start or awake and whenever the view is not yours you disable the camera of the person only and disable shooting. Its important to only do this on your computer! If you are not doing everyone will shoot when you press Shoot and everyone will walk when you walk.

How do I know when the fading coroutine is over when fading out or in?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Fading : MonoBehaviour
{
[Header("Fading")]
public List<GameObject> objectsToFade = new List<GameObject>();
public float duration;
public Coroutine fadeCoroutine;
public bool automatic = false;
public bool startFading = false;
[Header("Random")]
public bool randomObjects = false;
public bool randomDuration = false;
public bool faded = false;
private bool fadeInOut = false;
private bool coroutineIsRunning = false;
private List<Material> objectsToFadeMaterials = new List<Material>();
private bool randomOnce = false;
private Material randomMaterial;
private float originalDuration;
private void Start()
{
originalDuration = duration;
for (int i = 0; i < objectsToFade.Count; i++)
{
objectsToFadeMaterials.Add(objectsToFade[i].GetComponent<Renderer>().material);
}
}
private void Update()
{
if (startFading)
{
if (automatic)
{
if (!coroutineIsRunning)
{
Fade();
}
}
else
{
if (Input.GetKeyDown(KeyCode.G))
{
Fade();
}
}
}
}
private void Fade()
{
fadeInOut = !fadeInOut;
if (fadeCoroutine != null)
StopCoroutine(fadeCoroutine);
if(randomDuration)
{
duration = Random.Range(1, 20);
}
else
{
duration = originalDuration;
}
if (randomObjects && objectsToFade.Count > 1)
{
if (randomOnce == false)
{
randomMaterial = objectsToFadeMaterials[Random.Range(0, objectsToFadeMaterials.Count)];
randomOnce = true;
}
if (fadeInOut)
{
fadeCoroutine = StartCoroutine(FadeTo(randomMaterial, 0, duration));
}
else
{
fadeCoroutine = StartCoroutine(FadeTo(randomMaterial, 1, duration));
}
}
else
{
for (int i = 0; i < objectsToFadeMaterials.Count; i++)
{
if (fadeInOut)
{
fadeCoroutine = StartCoroutine(FadeTo(objectsToFadeMaterials[i], 0, duration));
}
else
{
fadeCoroutine = StartCoroutine(FadeTo(objectsToFadeMaterials[i], 1, duration));
}
}
}
}
public IEnumerator FadeTo(Material material, float targetOpacity, float duration)
{
Color color = material.color;
float startOpacity = color.a;
float t = 0;
coroutineIsRunning = true;
while (t < duration)
{
t += Time.deltaTime;
float blend = Mathf.Clamp01(t / duration);
color.a = Mathf.Lerp(startOpacity, targetOpacity, blend);
material.color = color;
if(t > duration)
{
coroutineIsRunning = false;
}
if(color.a == 1)
{
randomOnce = false;
}
if(color.a == 0)
{
faded = true;
}
yield return null;
}
}
}
I know that if the color.a is 0 then the object faded out finished then I set faded to true.
In the second script that is attached to a teleporter I want to start teleporting if the object faded out then teleport to the next teleporter and fade in back and so on.
This script is attached to each teleporter :
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
public class Teleport : MonoBehaviour
{
public Fading fading;
public List<GameObject> objectsToTeleport = new List<GameObject>();
//Start is called before the first frame update
void Start()
{
objectsToTeleport = GameObject.FindGameObjectsWithTag("ObjectToTeleport").ToList();
}
// Update is called once per frame
void Update()
{
}
private void OnTriggerEnter(Collider other)
{
StartCoroutine(fading.FadeTo(objectsToTeleport[0].GetComponent<Renderer>().material, 0, 2));
}
}
and this script is the teleporting script :
using System;
using System.Collections;
using System.Collections.Generic;
using System.Net.WebSockets;
using UnityEngine;
using UnityEngine.Scripting.APIUpdating;
public class Teleporting : MonoBehaviour
{
public List<ObjectToTeleport> objectsToTeleport;
public List<ObjectToTeleport> currentlyTeleportedObjects;
public List<GameObject> teleporters;
public float teleportingTime;
public float teleportingStartTime;
public bool startTeleporting = false;
public GameObject[] groups;
public bool loop = false;
public bool random = false;
public int teleportationsCount = 0;
[Serializable]
public class ObjectToTeleport
{
public GameObject teleportableObject;
public int teleportOrder;
}
public void Start()
{
StartTeleporting();
}
private void Update()
{
}
public void StartTeleporting()
{
if (startTeleporting)
{
if (teleporters.Count > 1 && objectsToTeleport.Count > 0)
{
InvokeRepeating("MoveTeleportableObjects", teleportingStartTime, teleportingTime);
}
}
}
private void MoveTeleportableObjects()
{
if (teleportationsCount < objectsToTeleport.Count)
currentlyTeleportedObjects.Add(objectsToTeleport[teleportationsCount]);
for (int i = 0; i < currentlyTeleportedObjects.Count; i++)
{
if (!loop)
{
MoveObjects(i);
}
else
{
MoveObjects(i);
}
}
teleportationsCount++;
}
private void MoveObjects(int i)
{
GameObject destinationTeleporter = teleporters[currentlyTeleportedObjects[i].teleportOrder];
currentlyTeleportedObjects[i].teleportableObject.transform.position = destinationTeleporter.transform.position;
if (currentlyTeleportedObjects[i].teleportOrder < teleporters.Count - 1)
{
currentlyTeleportedObjects[i].teleportOrder++;
}
else if (loop == true)
{
{
currentlyTeleportedObjects[i].teleportOrder = 0;
}
}
}
}
I need somehow a synchronization between the fading and the teleporting in the Teleport script.
But it seems a bit complicated.
The Fading script on it's own and the Teleporting script on it's own are working fine but making a synchronization between them is the problem.
Update :
What I tried :
In the Fading script I added two methods FadIn and FadeOut and calling the FadeOut in the Teleport script :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Fading : MonoBehaviour
{
[Header("Fading")]
public List<GameObject> objectsToFade = new List<GameObject>();
public float duration;
public Coroutine fadeCoroutine;
public bool automatic = false;
public bool startFading = false;
[Header("Random")]
public bool randomObjects = false;
public bool randomDuration = false;
public bool faded = false;
private bool fadeInOut = false;
private bool coroutineIsRunning = false;
private List<Material> objectsToFadeMaterials = new List<Material>();
private bool randomOnce = false;
private Material randomMaterial;
private float originalDuration;
private void Start()
{
originalDuration = duration;
for (int i = 0; i < objectsToFade.Count; i++)
{
objectsToFadeMaterials.Add(objectsToFade[i].GetComponent<Renderer>().material);
}
}
private void Update()
{
if (startFading)
{
if (automatic)
{
if (!coroutineIsRunning)
{
Fade();
}
}
else
{
if (Input.GetKeyDown(KeyCode.G))
{
Fade();
}
}
}
}
private void Fade()
{
fadeInOut = !fadeInOut;
if (fadeCoroutine != null)
StopCoroutine(fadeCoroutine);
if(randomDuration)
{
duration = Random.Range(1, 20);
}
else
{
duration = originalDuration;
}
if (randomObjects && objectsToFade.Count > 1)
{
if (randomOnce == false)
{
randomMaterial = objectsToFadeMaterials[Random.Range(0, objectsToFadeMaterials.Count)];
randomOnce = true;
}
if (fadeInOut)
{
fadeCoroutine = StartCoroutine(FadeTo(randomMaterial, 0, duration));
}
else
{
fadeCoroutine = StartCoroutine(FadeTo(randomMaterial, 1, duration));
}
}
else
{
for (int i = 0; i < objectsToFadeMaterials.Count; i++)
{
if (fadeInOut)
{
fadeCoroutine = StartCoroutine(FadeTo(objectsToFadeMaterials[i], 0, duration));
}
else
{
fadeCoroutine = StartCoroutine(FadeTo(objectsToFadeMaterials[i], 1, duration));
}
}
}
}
private IEnumerator FadeTo(Material material, float targetOpacity, float duration)
{
Color color = material.color;
float startOpacity = color.a;
float t = 0;
coroutineIsRunning = true;
while (t < duration)
{
t += Time.deltaTime;
float blend = Mathf.Clamp01(t / duration);
color.a = Mathf.Lerp(startOpacity, targetOpacity, blend);
material.color = color;
if(t > duration)
{
coroutineIsRunning = false;
}
if(color.a == 1)
{
randomOnce = false;
}
yield return null;
}
}
public IEnumerator FadeIn(Material material, float duration)
{
StartCoroutine(FadeTo(material, 1, duration));
yield return new WaitForSeconds(duration);
}
public IEnumerator FadeOut(Material material, float duration)
{
StartCoroutine(FadeTo(material, 0, duration));
yield return new WaitForSeconds(duration);
}
}
In the Teleport script
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
public class Teleport : MonoBehaviour
{
public Fading fading;
public List<GameObject> objectsToTeleport = new List<GameObject>();
//Start is called before the first frame update
void Start()
{
objectsToTeleport = GameObject.FindGameObjectsWithTag("ObjectToTeleport").ToList();
}
// Update is called once per frame
void Update()
{
}
private void OnTriggerEnter(Collider other)
{
StartCoroutine(fading.FadeOut(objectsToTeleport[0].GetComponent<Renderer>().material, 3));
}
private void OnTriggerExit(Collider other)
{
}
}
How do I continue from here ? what should I do next ?

There are multiple ways.
Simply yield the routine
You already have both as Coroutines so you could wrap them in another Coroutine and yield return it instead of StartCoroutine (this is something you should do in FadeIn and FadeOut anyway!)
// If this returns IEnumerator Unity automatically runs it as Coroutine
private IEnumerator OnTriggerEnter(Collider other)
{
yield return fading.FadeOut(objectsToTeleport[0].GetComponent<Renderer>().material, 3));
// Something after fading finished
Debug.Log("Fade Out finished!");
}
You could of course as well have them separately like
private void OnTriggerEnter(Collider other)
{
StartCorouine (EnterRoutine(other));
}
private IEnumerator EnterRoutine ()
{
yield return fading.FadeOut(objectsToTeleport[0].GetComponent<Renderer>().material, 3));
// Something after fading finished
Debug.Log("Fade Out finished!");
}
Callback
Another way would be passing in a callback that is executed once the routine finishes like e.g.
private void OnTriggerEnter(Collider other)
{
StartCoroutine(fading.FadeOut(objectsToTeleport[0].GetComponent<Renderer>().material, 3, OnFadeOutFinished));
}
private void OnFadeOutFinished ()
{
Debug.Log("Fade Out finished!", this);
}
or using a lambda, especially helpful if you want to do something with the other reference
private void OnTriggerEnter(Collider other)
{
StartCoroutine(fading.FadeOut(objectsToTeleport[0].GetComponent<Renderer>().material, 3, () => {
Debug.Log("Fade Out finished!");
}));
}
and have it as parameter in your routine like
private IEnumerator FadeTo(Material material, float targetOpacity, float duration, Action callback)
{
Color color = material.color;
float startOpacity = color.a;
float t = 0;
coroutineIsRunning = true;
while (t < duration)
{
t += Time.deltaTime;
float blend = Mathf.Clamp01(t / duration);
color.a = Mathf.Lerp(startOpacity, targetOpacity, blend);
material.color = color;
if(t > duration)
{
coroutineIsRunning = false;
}
if(color.a == 1)
{
randomOnce = false;
}
yield return null;
}
callback?.Invoke();
}
public IEnumerator FadeIn(Material material, float duration, Action callback = null)
{
yield return FadeTo(material, 1, duration, callback));
}
public IEnumerator FadeOut(Material material, float duration, Action callback = null)
{
yield return FadeTo(material, 0, duration, callback));
}

There are a lot of ways you could do this, but I personally in this case would create new coroutines FadeIn and FadeOut, instead of directly calling the following:
fadeCoroutine = StartCoroutine(FadeTo(objectsToFadeMaterials[i], 0, duration));
Then, at the end of your FadeOut coroutine you can take some additional step(s) to trigger a teleport or whatever else you need to trigger. It looks like you don't want your Fading to hold a reference to your Teleporting, which is smart, so you could choose to fire an event instead that your Teleporting component can subscribe to.

Bullet doens't move. Unity

I am working on a 2D, topdown, roguelike game but i got stuck when i tried to make a shooting system.
when i run it and press the arrow keys, the bullet spawns and points in the right direction. It juste doesn't move in any way.
This is my code and i hope someone can figure it out. Btw, everything is connected. The player and the bullet prefab.
using System.Collections;
using System.Linq;
using UnityEngine;
namespace Assets.Scripts
{
[RequireComponent(typeof(Player))]
public class PlayerShootController : ShootControllerBase
{
[SerializeField]
private int _numberOfBombs;

set { _numberOfBombs = value; }
}

private PlayerHeadController _headObject;
public PlayerHeadController HeadObject
{
get { return _headObject; }
set { _headObject = value; }
}

private Bomb _bombPrefab;
public Bomb BombPrefab
{
get { return _bombPrefab; }
set { _bombPrefab = value; }
}
public bool IsShooting { get; private set; }
private KeyCode _shootKey;
private Vector2 _shootDirection;
private Player _player;
public override void Start()
{
base.Start();
_player = GetComponent<Player>();
}
public override void Update()
{
base.Update();
if (IsShooting)
{
SetHeadDirection(_shootKey);
return;
}
if (InputHelpers.IsAnyKey(KeyCode.UpArrow, KeyCode.DownArrow, KeyCode.LeftArrow, KeyCode.RightArrow))
{
if (Input.GetKey(KeyCode.UpArrow))
{
_shootDirection = new Vector2(0, BulletSpeed);
_shootKey = KeyCode.UpArrow;
}
else if (Input.GetKey(KeyCode.DownArrow))
{
_shootDirection = new Vector2(0, -BulletSpeed);
_shootKey = KeyCode.DownArrow;
}
else if (Input.GetKey(KeyCode.LeftArrow))
{
_shootDirection = new Vector2(-BulletSpeed, 0);
_shootKey = KeyCode.LeftArrow;
}
else if (Input.GetKey(KeyCode.RightArrow))
{
_shootDirection = new Vector2(BulletSpeed, 0);
_shootKey = KeyCode.RightArrow;
}
StartCoroutine(Shoot());
}
if (NumberofBombs > 0 && InputHelpers.IsAnyKeyDown(KeyCode.LeftShift, KeyCode.RightShift, KeyCode.E))
{
var bomb = (Bomb) Instantiate(BombPrefab);
bomb.transform.position = transform.position;
NumberofBombs--;
}
}
IEnumerator Shoot()
{
IsShooting = true;
while (Input.GetKey(_shootKey))
{
var bullet = (Rigidbody2D)Instantiate(BulletPrefab);
bullet.GetComponent<BulletScript>().Shooter = transform.gameObject;
bullet.transform.position = transform.position;
if (_shootDirection.y > 0)
{
bullet.transform.Rotate(0, 0, -90);
}
else if (_shootDirection.y < 0)
{
bullet.transform.Rotate(0, 0, 90);
}
else if (_shootDirection.x > 0)
{
TransformHelpers.FlipX(bullet.gameObject);
}
bullet.AddForce(_shootDirection);
bullet.AddForce(_player.GetComponent<Rigidbody2D>().GetPointVelocity(_player.transform.position) * 0.02f);
if (ShootClips.Any())
{
var clipToPlay = ShootClips[Random.Range(0, ShootClips.Count)];
clipToPlay.pitch = Random.Range(MinShootPitch, MaxShootPitch);
clipToPlay.Play();
}
yield return new WaitForSeconds(ShootingSpeed);
}
IsShooting = false;
//Reset head flipping
if (_headObject.transform.localScale.x < 0)
{
TransformHelpers.FlipX(_headObject.gameObject);
}
}
private void SetHeadDirection(KeyCode shootKey)
{
switch (shootKey)
{
case KeyCode.UpArrow:
_headObject.SetHeadDirection(PlayerHeadController.HeadDirection.Up);
break;
case KeyCode.DownArrow:
_headObject.SetHeadDirection(PlayerHeadController.HeadDirection.Down);
break;
case KeyCode.LeftArrow:
_headObject.SetHeadDirection(PlayerHeadController.HeadDirection.Left);
break;
case KeyCode.RightArrow:
_headObject.SetHeadDirection(PlayerHeadController.HeadDirection.Right);
break;
}
}
}
}

try this:
bullet.AddForce(_shootDirection*moveSpeed*Time.deltaTime);
instead of this:
bullet.AddForce(_shootDirection);
bullet.AddForce(_player.GetComponent<Rigidbody2D>().GetPointVelocity(_player.transform.position) * 0.02f);
tweak the speed for desired result, and if you want the bullet to follow the player you will need to update the shoot direction every certain time with a couroutine

Unity: Need help how to double click detection in c#?

I wanna create mouse click that detect single click, hold click, and double click.
When I do single click, the character will faster (moveSpeed = 15), when I hold click and double click there is no action, the character still constant with it speed (moveSpeed = 3).
Here is my code:
private float t0, moveSpeed;
private bool longClick, shortClick;
void Start ()
{ t0 = 0f; longClick = false; shortClick = false; }
void update()
{
// how to add the code for detect double click and where I write it?
if (Input.GetMouseButtonDown (0))
{
t0 = 0; t0 += Time.deltaTime;
longClick = false; shortClick = false;
moveSpeed = 0;
}
if (Input.GetMouseButton(0))
{
t0 += Time.deltaTime;
if (t0 < 0.2)
{ moveSpeed = 15;longClick = false; shortClick = true; } // this is single click!
if (t0 > 0.2)
{ moveSpeed = 3; longClick = true; shortClick = false; } // this is hold click!
}
if (Input.GetMouseButtonUp(0))
{
if (longClick == true)
{ moveSpeed = 3; }
else if (shortClick = true)
{ moveSpeed = 3; }
}
}

Have you tried googling? - See the second answer here: http://answers.unity3d.com/questions/331545/double-click-mouse-detection-.html
In C#:
private float lastClickTime;
public float catchTime = 0.25f;
void Update ()
{
if(Input.GetButtonDown("Fire1"))
{
if(Time.time - lastClickTime < catchTime)
{
//double click
print("Double click");
}
else
{
//normal click
}
lastClickTime = Time.time;
}
}

I replied here: http://answers.unity3d.com/answers/1133702/view.html
Basically: create a new class with the doubleClicked checker inside. Then use it in an if clause.
class DoubleClickListener {
bool firstClick = false;
float runningTimerSecond;
float delay = 0.25F;
public DoubleClickListener() { }
public DoubleClickListener(float delay) {
this.delay = delay;
}
public bool isDoubleClicked() {
// If the time is too long we reset first click variable
if (firstClick && (Time.time - runningTimerSecond) > delay) {
firstClick = false;
}
if (!firstClick) {
firstClick = true;
runningTimerSecond = Time.time;
} else {
firstClick = false;
return true;
}
return false;
}
}

DoubleClickBehaviorBase is a base class that will take care of double click for you.
You inherit from DoubleClickBehaviorBase instead of MonoBehavior
All you need to do is override OnDoubleClickOverride in your class.
I've also included a MonoBehaviourExtension that makes it easier to call and
implement StartCoroutine:
namespace DoubleClick
{
public static class MonoBehaviourExtension
{
public static void StartCoroutine(this MonoBehaviour mb, params Action[] funcs)
{
mb.StartCoroutine(CoroutineRunnerSimple(funcs));
}
private static System.Collections.IEnumerator CoroutineRunnerSimple(Action[] funcs)
{
foreach (var func in funcs)
{
if (func != null)
func();
yield return new WaitForSeconds(.01f);
}
}
}
abstract public class DoubleClickBehaviorBase : MonoBehaviour
{
float _DoubleClickTimer = 0.0f;
float _DoubleClickDelay = 0.5f;
bool _WasClicked = false;
// Update is called once per frame
protected virtual void Update()
{
// this starts timing when a click occurs
//
if (this._WasClicked == true)
{
this._DoubleClickTimer += Time.deltaTime;
}
// this must be in update because it expires based on time and not clicks
//
if (this._DoubleClickTimer > this._DoubleClickDelay)
{
this._WasClicked = false;
this._DoubleClickTimer = 0.0f;
}
}
protected virtual void OnMouseDoubleClick()
{
}
protected virtual void OnMouseDown()
{
if (this._WasClicked == false && this._DoubleClickTimer < _DoubleClickDelay)
{
this._WasClicked = true;
}
else if (this._WasClicked == true &&
this._DoubleClickTimer < this._DoubleClickDelay)
{
this.StartCoroutine(() => this.OnMouseDoubleClick());
}
}
}
}
