Questions & Answers

I have 2 c# script, NPCManager and NPCs.
NPCManager.cs
using UnityEngine;
using System.Collections;

public class NPCManager : MonoBehaviour {
	public int npcID;
	public int npcStage;
	public string npcName;
	public string npcDialog;

	public NPCManager(int ID, int Stage, string Name, string Dialog)
	{
		npcID = ID;
		npcStage = Stage;
		npcName = Name;
		npcDialog = Dialog;
	}
}

the NPCs.cs
using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class NPCs : MonoBehaviour {

	public List<NPCManager> NPCList = new List<NPCManager>();
	
	void Start () {

		NPCList.Add( new NPCManager(1, 0, "test", "test" ) );
	}
}

there is no error, no warning.
in the inspector which NPCs added, when i start the game the list added 1 size but it say “None (NPCManager)”.

i want it show the NPCManager variable.

First of all, generally, you shouldn’t use class constructors on classes derived from monobehaviour. And I don’t get why you need that constructor at all.

Secondly, when you initiate a class in the member definition line, it’s the same thing as writing it into the constructor which is wrong for monobehaviour.

Remove the NPCManager constructor and try this for NPCs class:

public class NPCs : MonoBehaviour { 
    public List<NPCManager> NPCList;

    void Start () {
        NPCList = new List<NPCManager>();
        NPCList.Add( new NPCManager(1, 0, "test", "test" ) );
    }
}
