试试这个：

  //使这个静态的，所以它是你的ApplyRules（）方法进行访问。
公共静态布尔solvedp1 = FALSE;公共静态无效ApplyRules（）
{
    如果（Level.Rooms [0,0] .GetItem（红宝石）！= NULL
        ＆安培; Level.Rooms [1,0] .GetItem（蓝色宝石）！= NULL
        ＆安培; solvedp1 == FALSE）
    {
        Console.Clear（）;
        Console.WriteLine（你把宝石在正确的地方。只要创业板位置，你觉得一哆嗦和温暖的感觉进入你的脚趾，并穿过你的整个身体，在房间里的异样的感觉消失了。你听到锁开锁的门尖叫，因为它打开。）;
        Console.WriteLine（preSS回车键继续）;
        Console.ReadKey（）;
        solvedp1 = TRUE;
    }
}
 

I have a question, which might be very nooby, but I have been stuck on it for the last 3 days. I have a method called ApplyRules, which is used very frequently so I can't define a bool inside of it, but when I try to define it outside of the method, it doesn't read it. Here is my code:

public bool solvedp1 = false;

    public static void ApplyRules()
    {

        if (Level.Rooms[0, 0].GetItem("Red Gem") != null
            & Level.Rooms[1, 0].GetItem("Blue Gem") != null
            & solvedp1 == false)
        {
            Console.Clear();
            Console.WriteLine("You put the gem in its correct place. As soon as the gem is in position, you feel a shiver and a warm feeling enters your toes and passes through your whole body. The strange feeling in the room is gone. You hear a lock unlocking and a door shrieking as it opens..");
            Console.WriteLine("Press enter to continue");
            Console.ReadKey();
            solvedp1 = true;
        }

Try this:

//Make this static so it is accessible to your ApplyRules() method.
public static bool solvedp1 = false;

public static void ApplyRules()
{
    if (Level.Rooms[0, 0].GetItem("Red Gem") != null
        & Level.Rooms[1, 0].GetItem("Blue Gem") != null
        & solvedp1 == false)
    {
        Console.Clear();
        Console.WriteLine("You put the gem in its correct place. As soon as the gem is in position, you feel a shiver and a warm feeling enters your toes and passes through your whole body. The strange feeling in the room is gone. You hear a lock unlocking and a door shrieking as it opens..");
        Console.WriteLine("Press enter to continue");
        Console.ReadKey();
        solvedp1 = true;
    }
}
