I can't seem to get this to work.
The player presses 1 or 2 or 3 etc depending where the weapon is on the hotbar and it will show the weapon by setting it active in the hierarchy.
everything works fine client side obviously but I cannot get it to show from the other players perspective. Not sure where to put the photon view or where to put the code exactly but this is my code that is currently on the hotbar slot.
Also worth mentioning that the item is selected from an actual inventory and not just a simple switch so it all corresponds to another bit of code that is the item script attached to the pickupable item.
Thanks if advanced if anyone can point me in the right direction.

The game is working correctly and there arent any other issues apart from the fact that the public fields from the players scripts that are supposed to be filled with game objects from the scene arent filled and im not sure how to do that.
heres an example from one of the scripts: image
and heres what it should look like: image
the joystick area from the second image is from the scene, not an asset: image
here is the code im using:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MovePlayer : MonoBehaviour
{
public MovementJoystick movementJoystick;
public int playerSpeed;

// Start is called before the first frame update
void Start()
{
rb = GetComponent<Rigidbody2D>();
playerSpeed = 7;
interval = 10;
}
// Update is called once per frame
void FixedUpdate()
{
if (movementJoystick.joystickVec.y != 0)
{
rb.velocity = new Vector2(movementJoystick.joystickVec.x * playerSpeed, movementJoystick.joystickVec.y * playerSpeed);
animator.SetFloat("speed", Mathf.Abs(movementJoystick.joystickVec.x));
}
else
{
rb.velocity = Vector2.zero;
animator.SetFloat("speed", Mathf.Abs(0));
}
if (movementJoystick.joystickVec.x < 0 && !facingRight)
{
Flip();
}
if (movementJoystick.joystickVec.x > 0 && facingRight)
{

}
}

this is how to instantiate the player using photon servers (what i am using)
public GameObject playerToSpawn;
PhotonNetwork.Instantiate(playerToSpawn.name, spawnPoint.position, Quaternion.identity);
There are also 2 buttons i need you to fix: a Shoot button and a Hit button (those are the names). Here is the code for them:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class ShootButton : MonoBehaviour
{
//i made this script for the button incase you may
have
needed it
}
Here is the shooting script attached to the player:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Weapon : MonoBehaviour
{
public Transform firePoint;
public GameObject bulletPrefab;
public Button ShootButton;
void Start()
{
ShootButton.onClick.AddListener(ShootButtonTrue);
}
void ShootButtonTrue()
{
Shoot();
}
void Shoot()
{
Instantiate(bulletPrefab, firePoint.position,
firePoint.rotation);
}
}
Here is the hitting script attached to the Hit button
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class HitButton : MonoBehaviour
{
}
And here is the Player Combat script using for hitting:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class PlayerCombat : MonoBehaviour
{
public Animator animator;
public Button AttackButton;
public Transform attackPoint;
public float attackRange = 0.5f;
public LayerMask enemyLayers;
void Start()
{
AttackButton.onClick.AddListener(AttackButtonTrue);
}
void AttackButtonTrue()
{
Attack();
}
void Attack()
{
animator.SetTrigger("Attack");
Collider2D[] hitEnemies = Physics2D.OverlapCircleAll(attackPoint.position, attackRange, enemyLayers);
foreach(Collider2D enemy in hitEnemies)
{
Debug.Log("u hit someone :O");
enemy.GetComponent<Health>().TakeDamage(15);
}
}
void OnDrawGizmosSelected()
{
if (attackPoint == null)
return;
Gizmos.DrawWireSphere(attackPoint.position, attackRange);
}
}
if you need any other pieces of code just ask
thanks in advance, i will mark the answer as an answer if its a good answer
There are multiple ways to achieve this. For example, you can make your joystick singleton and assign that to the player upon spawn. If you have multiple joysticks in the scene, you can group them under the same parent object and make that parent singleton.
Assuming you only have one joystick in the scene, add this into your joystick class:
public static MovementJoystick Instance { get; private set; }
void Awake()
{
if (Instance != null && Instance != this)
{
Destroy(this);
}
else
{
Instance = this;
}
}
In your player class, add this:
void OnEnable()
{
if( movemaneJoystick == null)
{
movementJoystick = MovementJoystick.Instance;
}
}
I have been stuck on this problem for a few months now. The problem being that I cannot properly instantiate my prefabs in the scene I want. I need the spawning to be one person on one team, and the rest on the other. But I'm not sure how to do that. What happens is that when I click the play button on my lobby menu, I get an error called "No cameras to display." I also noticed that the scene I want does load, but it doesn't switch to it because there are no cameras that are instantiated. I am using Photon 2. I am new to game development and your guys' help would be greatly appreciated! :)
I will post my code if that will help:

When I press Space, the player and the dummy are supposed to swap places. This doesn't just happen once, it needs to happen everytime I press the Space bar so they can swap back and forth. However, sometimes it works and sometimes it doesn't. When it doesn't work, the dummy teleports to the player and then the player teleports inside of the dummy (as that is where its last position is). This just kind of pushes the player about.
Here is the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerSwap : MonoBehaviour
{
public GameObject player;
public GameObject dummy;
public GameObject cameraAnchor;
public Transform playerLastPos;
public Transform dummyLastPos;
public bool haveSwapped;
public bool canSwap;
public float swapRadius;
public LayerMask dummyInRadius;
// Update is called once per frame
void Update()
{
canSwap = Physics.CheckSphere(player.transform.position, swapRadius, dummyInRadius);
SwapTransforms();
if (canSwap)
{
if (Input.GetKeyDown(KeyCode.Space))
{
haveSwapped = !haveSwapped;
Swapping();
}
}
else
{
Debug.Log("Can't Swap");
}
cameraAnchor.transform.position = player.transform.position;
}
public void SwapTransforms()
{
if (haveSwapped)
{
dummyLastPos.position = player.transform.position;
playerLastPos.position = dummy.transform.position;
}
else
{
dummyLastPos.position = dummy.transform.position;
playerLastPos.position = player.transform.position;
}
}
public void Swapping()
{
if (haveSwapped)
{
player.transform.position = dummyLastPos.position;
dummy.transform.position = playerLastPos.position;
}
else
{
player.transform.position = playerLastPos.position;
dummy.transform.position = dummyLastPos.position;
}
}
public void OnDrawGizmos()
{
Gizmos.color = Color.white;
Gizmos.DrawWireSphere(player.transform.position, swapRadius);
}
}
I've solved it. After cleaning up most of the code and realsing I had to turn off movement and the character controller on the player (Link:Unity Answers), I came up with this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerSwap : MonoBehaviour
{
public ThirdPersonMovement playerMove;
public GameObject player;
public GameObject dummy;
public GameObject cameraAnchor;
public Transform playerLastPos;
public Transform dummyLastPos;
public bool canSwap;
public float swapRadius;
public LayerMask dummyInRadius;
// Update is called once per frame
void Update()
{
canSwap = Physics.CheckSphere(player.transform.position, swapRadius, dummyInRadius);
if (canSwap)
{
if (Input.GetKeyDown(KeyCode.Space))
{
playerMove.canMove = false;
player.GetComponent<CharacterController>().enabled = false;
SetTransforms();
}
}
else
{
Debug.Log("Can't Swap");
}
cameraAnchor.transform.position = player.transform.position;
}
public void SetTransforms()
{
dummyLastPos.position = dummy.transform.position;
playerLastPos.position = player.transform.position;
Debug.Log("Set Transforms");
Swapping();
}
public void Swapping()
{
player.transform.position = dummyLastPos.position;
dummy.transform.position = playerLastPos.position;
dummy.transform.rotation = player.transform.rotation;
Debug.Log("Swap");
playerMove.canMove = true;
player.GetComponent<CharacterController>().enabled = true;
}
public void OnDrawGizmos()
{
Gizmos.color = Color.white;
Gizmos.DrawWireSphere(player.transform.position, swapRadius);
}
}
At the moment I am programming a Unity 2D game. When the game is running the cars start moving and respawn continuously. I added kind of a life system to enable the possibility to shoot the cars. My issue is that my health bar as well as my score board need references to the objects they refer to, but I am unable to create a reference to an object which is not existing before the game starts. Another issue is that I don't know how to add a canvas to a prefab in order to spawn it with the cars continuously and connect them to the car. Is there a way to avoid these conflicts or how is it possible to set the references into prefabs. I will add the code of the spawner, the car and the the scoreboard. Already thank you in advance
Spawner:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Spawner : MonoBehaviour
{
public GameObject carPrefab;
public GameObject enemyCarPrefab;
public GameObject kugel;
public float respawnTime = 10.0f;
public int counterPlayer1=0;
public int counterPlayer2=0;
public int counterEnergy=0;
// Use this for initialization
void Start () {
StartCoroutine(carWave());
}
private void spawnPlayerCars(){
GameObject a = Instantiate(carPrefab) as GameObject;
a.transform.position = new Vector2(-855f, -312.9426f);
counterPlayer1++;
}
private void SpawnEnemyCars(){
GameObject b = Instantiate(enemyCarPrefab) as GameObject;
b.transform.position = new Vector2(853,-233);
counterPlayer2++;
}
private void SpawnEnergy(){
GameObject c = Instantiate(kugel) as GameObject;
c.transform.position = new Vector2(-995,-192);
counterEnergy++;
}
IEnumerator carWave(){
while(true){
yield return new WaitForSeconds(respawnTime);
if(counterPlayer1<3){
spawnPlayerCars();
Debug.Log(counterPlayer1);
}
if(counterPlayer2<3){
SpawnEnemyCars();
Debug.Log(counterPlayer2);
}
if(counterEnergy<3){
SpawnEnergy();
}
}
}
}
Car:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class EnemyCar : MonoBehaviour
{
public float speed = 3f;
int zählerAuto1=0;
private Vector2 screenBounds;
public AnzeigePunktzahlPlayer2 points;
public Spawner sp;
public int maxHealth=100;
public int currentHealth;
public HealthBar healthbar;
void Start () {
screenBounds = Camera.main.ScreenToWorldPoint(new Vector2(Screen.width, Screen.height));
points= GetComponent<AnzeigePunktzahlPlayer2>();
sp= GetComponent<Spawner>();
currentHealth=maxHealth;
healthbar.SetMaxHealth(maxHealth);
}
void Update()
{
Vector2 pos = transform.position;
if(pos.x>-855f){
pos = transform.position;
pos.x-= speed* Time.deltaTime;
transform.position=pos;
zählerAuto1++;
}else{
points.counter++;
Debug.Log(points.counter);
sp.counterPlayer2--;
Debug.Log(sp.counterPlayer2);
Destroy(this.gameObject);
}
}
private void OnCollisionEnter2D(Collision2D other) {
if (other.collider.tag=="Kugel"){
takeDamage(40);
//sp.counterPlayer2--;
if(currentHealth<=0)
{
Destroy(this.gameObject);
}
}
}
public void takeDamage(int damage){
currentHealth-= damage;
healthbar.SetHealth(currentHealth);
}
public void getHealed(int heal){
currentHealth+= heal;
healthbar.SetHealth(currentHealth);
}
}
Scoreboard(one part of it(the other one is almost the same)):
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
public class AnzeigePunktzahlPlayer1 : MonoBehaviour
{
public int counter;
public TextMeshProUGUI textPlayer1;
void Start()
{
// counter=0;
textPlayer1= GetComponent<TextMeshProUGUI>();
}
// Update is called once per frame
void Update()
{
textPlayer1.SetText( counter.ToString());
}
}
You could make the health bars and the canvas children of the Car prefab and have them spawn together.

Thank you for choosing Photon!
You need to get the count of actors (PhotonNetwork.CurrentRoom.PlayerCount) when you join the room (OnJoinedRoom) or when another player joins the room (OnPlayerEnteredRoom). When the number of actors joined is enough for you, start the game logic, e.g. load scene, send a custom event etc.
