Questions & Answers

I want to instantiate some object. But Unity alwys sais “ArgumentException: The Object you want to instantiate is null.” I HAVE this prefab in Resources folder, and names are correct i check it. My code:

public void Load(string savename){
		XElement AllObjects = null;
		if(File.Exists(path + "/Savedata/" + savename + ".xml")){
			AllObjects = XDocument.Parse(File.ReadAllText(path + "/Savedata/" + savename + ".xml")).Element("AllObjects");
		}
		foreach (GameObject obj in savable) {
			Destroy (obj);
		}
		foreach (XElement instance in AllObjects.Elements("instance")) {
			LoadObject (instance);
		}
	}
private void LoadObject(XElement obj){
		Vector3 position = Vector3.zero;
		Quaternion rotation = Quaternion.identity;
		position.x = float.Parse(obj.Attribute("x").Value);
		position.y = float.Parse(obj.Attribute("y").Value);
		position.z = float.Parse(obj.Attribute("z").Value);
		rotation.x = float.Parse(obj.Attribute("rotx").Value);
		rotation.y = float.Parse(obj.Attribute("roty").Value);
		rotation.z = float.Parse(obj.Attribute("rotz").Value);
		Debug.Log (obj.Value + "Here!!!!!!!!");
		Instantiate (Resources.Load(obj.Value) as GameObject, position, rotation);
	}

It`s simple: i called the resources like “Resouces” facepalm

I’m having this error:
ArgumentException: The prefab you want to instantiate is null.
UnityEngine.Object.CheckNullArgument (System.Object arg, System.String message) (at C:/buildslave/unity/build/artifacts/EditorGenerated/UnityEngineObject.cs:104)
UnityEngine.Object.Instantiate (UnityEngine.Object original, Vector3 position, Quaternion rotation) (at C:/buildslave/unity/build/artifacts/EditorGenerated/UnityEngineObject.cs:83)
DefenderSpawner.OnMouseDown () (at Assets/Scripts/DefenderSpawner.cs:22)
UnityEngine.SendMouseEvents:DoSendMouseEvents(Int32, Int32)
and this is the code it’s referring to:
DefenderSpawner.cs:
using UnityEngine;
using System.Collections;

public class DefenderSpawner : MonoBehaviour {

public Camera myCamera;
private GameObject parent;

void Start () {
	parent = GameObject.Find ("Defenders");
	
	if (!parent) {
		parent = new GameObject("Defenders");
	}
}

void OnMouseDown () {
	Vector2 rawPos = CalculateWorldPointOfMouseClick();
	Vector2 roundedPos = SnapToGrid (rawPos);
	GameObject defender = Button.selectedDefender;
	Quaternion zeroRot = Quaternion.identity;
	GameObject newDef = Instantiate (defender, roundedPos, zeroRot) as GameObject;
	
	newDef.transform.parent = parent.transform;
}

Vector2 SnapToGrid (Vector2 rawWorldPos) {
	float newX = Mathf.RoundToInt (rawWorldPos.x);
	float newY = Mathf.RoundToInt (rawWorldPos.y);
	return new Vector2 (newX, newY);
}

Vector2 CalculateWorldPointOfMouseClick () {
	float mouseX = Input.mousePosition.x;
	float mouseY = Input.mousePosition.y;
	float distanceFromCamera = 10f;
	
	Vector3 weirdTriplet = new Vector3 (mouseX, mouseY, distanceFromCamera);
	Vector2 worldPos = myCamera.ScreenToWorldPoint (weirdTriplet);
		
	return worldPos;
}

}
