Hi, I am creating a game on unity and I don't know how to fix the error. Does anyone know how t-CodePudding

I am trying to get all of the game objects with the tag of player but it comes up with the error "Cannot implicitly convert type int to UnityEngine.GameObject[]". My code is:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Photon.Pun;

public class mymanager : MonoBehaviour
{
    GameObject[] amount;
    public GameObject winPanel;

    void Start()
    {
        winPanel.SetActive(false);
    }

    // Update is called once per frame
    void Update()
    {
        amount = GameObject.FindGameObjectsWithTag("Player").Length;

        if(amount <= 1)
        {
            winPanel.SetActive(true);
        }
        else
        {
            winPanel.SetActive(false);
        }
    }

    public void OnClickJoinLobby()
    {
        PhotonNetwork.LoadLevel("Lobby");
    }
}

I wanted to count the amount of players and open a UI panel if there was a maximum of 1 player left.

CodePudding user response：

You gave the array of Gameobject amount an int value which is wrong, you need to give it Gameobjects, delete .length

amount = GameObject.FindGameObjectsWithTag("Player");

And in the if condition check the length of it like this

if(amount.Length <= 1)
{
///
}

CodePudding user response：

GameObject.FindGameObjectsWithTag("Player").Length returns the length of the array returned by GameObject.FindGameObjectsWithTag("Player").

If you only want how many player exists, you don't need the GameObject[] amount, just check the length:

int amount = GameObject.FindGameObjectsWithTag("Player").Length;
if (amount <= 1) ...

Or if you want to do with them something, then

private GameObject[] _players;

...

_players = GameObject.FindGameObjectsWithTag("Player");
int amount = _players.Length;

...
