Unity Engine
1

I have this error:
NullReferenceException: Object reference not set to an instance of an object
awk.Awake () (at Assets/Scipts/awk.cs:9)

Awk:

using UnityEngine;
using System.Collections;

public class awk : MonoBehaviour {

        void Awake()
    {
        //Setting the default values may change in future!
        GameManger.control.player_money = 0;
        GameManger.control.Player_damage = 1;
        GameManger.control.player_xp = 0;
        GameManger.control.xp_req = 5;
        GameManger.control.player_armor = 1;
        GameManger.control.player_health = 100;
        GameManger.control.player_potions = 0;
        GameManger.control.player_armorpen = 1;
        GameManger.control.player_level = 1;
        GameManger.control.player_xp_modifier = 1.5f;
        GameManger.control.boosterpacks = 0;
        GameManger.control.player_name = "Oachkatznal";
        GameManger.control.dead = false;
        GameManger.control.Quest = "HUEHUEHUEHUE";
        //Enemy
        GameManger.control.monster_name = "Unnamed";
        GameManger.control.monster_xp_reward = 1;
        GameManger.control.monster_damage = 2;
        GameManger.control.monster_armor = 1;
        GameManger.control.monster_armorpen = 1;
        GameManger.control.monster_health = 5;
        GameManger.control.monster_dead = false;
        GameManger.control.monster_gold_reward = 1;
        GameManger.control.xp_req = 5;
        GameManger.control.player_xp_modifier = 1.5f;
        GameManger.control.player_xp = 0;

       

    }
}

GameManger:

using UnityEngine;
using System.Collections;

public class GameManger : MonoBehaviour
{
   
        public static GameManger control;


        public string Quest;
        public double time;

        public int player_money;
        public int Player_damage;
        public int player_xp;
        public int xp_req;
        public int player_armor;
        public int player_health;
        public int player_potions;
        public int player_armorpen;
        public int player_level;
        public float player_xp_modifier;
        public int boosterpacks;
        public string player_name;
        public bool dead;

        //Enemy stats
        public string monster_name;
        public int monster_xp_reward;
        public int monster_gold_reward;
        public int monster_damage;
        public int monster_armor;
        public int monster_armorpen;
        public int monster_health;
        public bool monster_dead;


        void Awake ()
        {
        gameObject.tag = "Manger";
                if (control == null) {
                        DontDestroyOnLoad (gameObject);
                        control = this;
                } else if (control != this) {
                        Destroy (gameObject);
                }
        }

}

I have no idea why is this happening any help appriciated.

Move the awk script from Awake to Start. As a general rule, you shouldn’t have code that relies on other objects being already initialized in Awake.

See if that helps.

If you need the awk script to initialize on Awake, you can change the script order execution. Or just do what @Zaladur said and move it to Start to allow GameManager to finish initializing OR make a static property that will initialize it when it gets called the first time, this is the Singleton Paradigm.
