    "public" public objects

    Say I have a public class "class1" and in it is a public int "myint".
    No matter where I create an object with that class, it's not truly global, because it only works in the function I define it in. So if I define it in main it doesnt travel to any other functions. I get an error if I try to define it in just the class.

    What I'm asking is how to I make a class that I can make an object with that can be used anywhere in my program?
    Boy you stink, go take a shower before you continue to code. Better do your laundry and spray your chair too.

    Code:
    namespace mynamespace
    {
        public class myclass
        {
            public int asdf = 1;
            //other stuff
         }
    }
    That seems to work for me. What error are you getting when you just define it in the class?

    Code:
    using System;
    
    namespace Consoleapp1
    {
                    public class Character
    	{
    		public string name;
    		public int level;
    		public int xp;
    		public int attack;
    		public int damage;
    		public int hp;
    		public int str;
    		public int dex;
    		public int con;
    		public int ranged;
    		public int melee;
    		public int blocking;
    		public int dodging;
    	}
    	public class Class1
    	{
    		public static void Main(string[] args)
    		{
    		}
    		public static void CharGen()
    		{
    		}
    		public static void SetAllZero()
    		{
    		}
    	}
    }
    Basically what I am trying to do is create an object somewhere with the class "Character", and be able to modify the variables of that object in any function. I can only get it to work with one function. If I make an object in main called "player" with the class "Character" I can't modify the object's variables in "SetAllZero()"

    First, you will need a constructer for the class Character.

    After that, in main, declare your character as:
    Code:
     Character g = new Character(any values you need here);
    Then in SetAllZero, pass g and do whatever you need there.
    Code:
    SetAllZero(Character g)
    That's how I got it to work anyways.


    EDIT: This is the code I used, you should be able to alter it to your needs:
    Code:
    using System;
    
    namespace Consoleapp1
    {
        public class Character
    	{
    		public string name;
    		public int level;
    		public int xp;
    		public int attack;
    		
    		public Character(string n)
    		{
    			this.name = n;
    			this.level = 0;
    			this.xp = 0;
    			this.attack = 0;
    		}
    	}
        public class Class1
    	{
    		
    		public static void Main(string[] args)
    		{
    			Character g = new Character("bob");
    			System.Console.Write(g.name);
    			SetAllZero(g);
    		}
    		public static void CharGen(string n)
    		{
    		}
    		public static void SetAllZero(Character g)
    		{
    			g.attack = 1;
    			System.Console.Write(g.attack);
    		}
    	}
    }

    I have encountered a new problem. I included the clearing function you supplied above. No matter what I do, anything I put in between the two while statements gets skipped over like it's not even there. The switches only go through 4 times, and it should be 5.

    Code:
    using System;
    using nsClearConsole;
    
    
    namespace Consoleapp1
    {
    	public class Character
    	{
    		public string name;
    		public int level;
    		public int xp;
    		public int attack;
    		public int str;
    		public int dex;
    		public int con;
    		public int hp;
    		public int ac;
    		public int ranged;
    		public int melee;
    		public int dodge;
    		public int block;
    		public int dmg;
    		
    		public Character()
    		{
    			this.level = 0;
    			this.xp = 0;
    			this.attack = 0;
    			this.str = 0;
    			this.dex = 0;
    			this.con = 0;
    			this.hp = 0;
    			this.ac = 0;
    			this.ranged = 0;
    			this.melee = 0;
    			this.dodge = 0;
    			this.block = 0;
    			this.dmg = 0;
    			this.name = "";
    		}
    	}
    	public class Class1
    	{
    		
    		public static void Main(string[] args)

    			Character player = new Character();
    			Console.Write("Welcome to C# test game\n");
    			Console.Write("Press enter to start creating your character\n");
    			Console.ReadLine();
    			CharGen(player);
    		}

    			ClearMyConsole.Clear();
