Question by Rnugteren · Apr 20, 2020 at 08:51 AM · beginnerinstantiation

How do I create a player with variables?

Hello Unity!

I am very new to Unity. I do have some experience in C#, but I'm a little rusty, as it's been quite a while!

I want to create a player, with a given name, and for example starting gold, so I made a prefab for this:

 public class Player : MonoBehaviour
 {
     private string name; // field
     public string Name   // property
     {
         get { return name; }
         set { name = value; }
     }
 
     private float gold; // field
     public float Gold  // property
     {
         get { return gold; }
         set { gold = value; }
     }
 

now my problem comes when I want to instantiate the player. (there won't ever be the need to move around, as there won't be a physical player in the game. I figured I'd need a PlayerManager script, which would instantiate the player, and also update the players properties?

 public class PlayerManager : MonoBehaviour
 {
     Player myPlayer = new Player();
 
     // Start is called before the first frame update
     void Start()
     {
        // Load the player
         myPlayer.Name = "Bob";
         myPlayer.Gold = 10;
         myPlayer.givePlayerStatus(myPlayer.Name, myPlayer.Gold);
     }
 
 
     public string getGold()
     {
         return "You have " + myPlayer.Gold + " Gold";
     }

I created an empty object Gamemanager, and one for Player Manager, but I get a NullReference exception for my GameManager:

 public class GameManager : MonoBehaviour
 {
     Text Goldtext;
     PlayerManager myPlayerManager;
 
     // Start is called before the first frame update
     void Start()
     {
         // load the player via playerManager
         PlayerManager myPlayerManager = new PlayerManager();
     }
 
     // Update is called once per frame
     void Update()
     {
         string output = myPlayerManager.getGold(); //NullRefefenceException here
         Goldtext.text = output;
     }
 } 


I'm sure I'm missing one step here somewhere, but I can't just figure it out yet, and I've watched half a dozen tutorials, but they're mostly only covering movement etc.

What am I missing?

Thanks!
