UnityException：不允许调用此函数

Question

Y'all remember that game where you had a wooden board and tried to get the ball through the maze w/o avoiding pitfalls? I am making a clone of that (except on the six sides of a cube). Instead of pitfalls, I added bombs that players have to actively disarm before they can progress. I recently added some code to make it more user friendly, but I keep on getting the error:

UnityException: You are not allowed to call this function when declaring a variable. Move it to the line after without a variable declaration. If you are using C# don't use this function in the constructor or field initializers, Instead move initialization to the Awake or Start function. UnityEngine.GameObject..ctor () (at C:/buildslave/unity/build/artifacts/generated/common/runtime/UnityEngineGameObject.gen.cs:419) RandoLetter..cctor () Rethrow as TypeInitializationException: An exception was thrown by the type initializer for RandoLetter

RandoLetter is the script that creates the code for the player to destroy the bomb, but its acting up for some reason. Here is the code:

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

public class RandoLetter : MonoBehaviour { //The array list of bombs public static GameObject Bombs = new GameObject();

 //Array List of Particles
 public static GameObject Particles = new GameObject();

 //The list of colliders on the bombs
 public static Collider Triggers = new Collider();
 //The symbol that shows up
 int LetterID;

 //The speed at which a new symbol appears
 int counter, CounterMax;

 //The number of symbols that appear in one instance
 int LetterCount;

 //Which slot in the array that the player is accessing
 public int entryID;

 //The symbols that appear
 public GameObject[] Arrows = new GameObject[4];

 //The arrow buttons

 public static GameObject ArrowBTN;

 //The randomly generated code
 int[] PassCode = new int[4];

 //The player game object to be destroyed
 public GameObject player;

 //The buttons that let the player rotate
 public GameObject MoveUI;

 //The particle effect when the player dies
 public GameObject death;

 //The timer before the player or bomb expires
 int DeathCounter;

 //The code that the player puts in
 int[] YourCode = new int[4];
 int CounterToMax = 0;

 //Is the bomb currently being disarmed?
 public static bool disarming = false;

 void RestoreStart()
 {
     //How much longer until the next symbol appears
     CounterToMax = 0;
     //Is the player attempting to disarm the bomb
     disarming = false;

     //How many symbols show up
     LetterCount = 4;

     //Which slot in the array is the player accessing
     entryID = 0;

     //The UI that lets the player punch in part of the code
     BallMoving.BombU.SetActive(false);

     //Disabling the previous UI for the code
     SetUIFalse();
 }
 // Use this for initialization

     //The timer until the player expires after failing to disarm a bomb
     DeathCounter = 1000;

     //The slot in the array that the player is accessing
     entryID = 0;

     //The amount of characters in the code being presented to the player
     LetterCount = 4;

     //The time between arrows
     counter = 50;

Sorry if it looks like a bunch of junk, I tried to comment it as best as I could. Anyways, it has been bugging me for a while and I really appreciate any help :D

Answer 1

You have to create a new instance of GameObject inside a function.

Replace public static GameObject Particles = new GameObject();

with

public static GameObject Particles;

void Awake()
{
    Particles = new GameObject();
}
