The script show all the hierarchy scene objects in the editorwindow.
I want then in the editorwindow to manipulate and make changes to the objects.
The problem is that scrolling up down between the objects and childs is very slow not like in the original hierarchy window that is much faster.
The main goal is to show the hierarchy scene gameobjects in the editorwindow and then work on the objects in the editor window.

From what I can see your foreach loop is constantly getting a sibling index every iteration along with all the gameObjects in the scene. You should initially grab the gameobjects store them into a class with variables and then add that to a Collection. Iterate that collection and just pull the values.
EditorGUIHierarchyView hierarchyView = new EditorGUIHierarchyView();
private static GameObject[] _sceneObjects;
[MenuItem("Window/EditorGUIHierarchy - Show Scene View")]
static void Init()
{
EditorGUIHierarchyViewExampleWindow window = (EditorGUIHierarchyViewExampleWindow)GetWindow(typeof(EditorGUIHierarchyViewExampleWindow));
_sceneObjects = SceneManager.GetActiveScene().GetRootGameObjects();
Array.Sort(_sceneObjects, new SceneGameObjectComparer());
window.Show();
}
struct SceneGameObjectComparer : IComparer<GameObject>
{
public int Compare(GameObject go1, GameObject go2)
{
return go1.transform.GetSiblingIndex().CompareTo(go2.transform.GetSiblingIndex());
}
}
void OnEnable()
{
this.titleContent = new GUIContent("Scene View");
}
public void OnGUI()
{
hierarchyView.BeginHierarchyView();
foreach (GameObject gameObject in _sceneObjects)
{
gameObject.transform.GetSiblingIndex();
DrawGameObject(gameObject);
}
hierarchyView.EndHierarchyView();
Repaint();
}
void DrawGameObject(GameObject go)
{
if (go.transform.childCount > 0)
{
if (go.activeInHierarchy)
{
hierarchyView.BeginNode(go.name);
}
else
{
hierarchyView.BeginNode(go.name, Color.gray, Color.gray);
}
foreach (Transform child in go.transform)
{
DrawGameObject(child.gameObject);
}
hierarchyView.EndNode();
}
else
{
if (go.activeInHierarchy)
{
hierarchyView.Node(go.name);
}

hierarchyView.Node(go.name, Color.gray, Color.gray);

Prefab instantiating outside of viewport, and giving null reference exception in Unity C#

So, I'm aware that null reference exceptions are a pretty commonly brought up issue on here, but I'm genuinely stuck on this, as this code went from working fine to really not working, and I can't figure out why. I used this tutorial as a starter to get to where I am, https://www.youtube.com/watch?v=2TYLBusJKjc, and then added/adapted for my purposes. I then copied the buttonlistcontrol and buttonlistbutton script files, and renamed and edited them to use as a separate settings menu, which is when it all went downhill.
[SerializeField]
public GameObject upButtonTemplate, buttonTemplate, headingTemplate;
public void GenButtons()
{
ClearAll();
bankIms = Resources.LoadAll("buttons/bank", typeof(Sprite));
coinIms = Resources.LoadAll("buttons/coin", typeof(Sprite));
bgIms = Resources.LoadAll("BgPrevs", typeof(Sprite));
upgrades = new string[]{"text,some more text, even more text none of which matters here"};
upPrices[0] = gameManager.bank;
GenHeading("UPGRADES");
for (int i = 0; i < upgrades.Length; i++)
{
GameObject button = Instantiate(upButtonTemplate) as GameObject;
button.SetActive(true);
Debug.Log("button: " + button);
button.GetComponent<ButtonListButton>().ButtonSetup("upgrade", i); // Null Reference occuring on this line
button.GetComponent<ButtonListButton>().SetUpText(upgrades[i]);
button.GetComponent<ButtonListButton>().SetPrice(upPrices[i]);
button.transform.SetParent(upButtonTemplate.transform.parent,false);
upButts.Add(button);
}
void GenHeading(string head)
{
GameObject heading = Instantiate(headingTemplate) as GameObject;
heading.SetActive(true);
heading.GetComponent<TextMeshProUGUI>().text = head;
heading.transform.SetParent(headingTemplate.transform.parent,false);
headings.Add(heading);
}
When GenButtons is run now, the heading is still being created as expected, but I get an error Object reference not set to an instance of an object, and a clone of the button prefab gets added outside the canvas.
Heading added as expected, but StoreListUpgrade is wildly and annoyingly off
Any help that could sort it would be thoroughly appreciated.

I think the formatting went a bit off there, apologies for that.

When you are building an APK file it can be splited to APK + OBB.
So, it is possible that you are trying to load a scene that is absent in your APK. You need to force the creation of the APK without the OBB. To do it you need to check Player Settings in Android, go to Publishing Settings and uncheck Split Application Binary.

Porblem with game once builded

in my game to pass from one level to another you must answer some questions. Each question has an associated image. For each level of play there is a different set of questions. During the Unity game simulation there is no problem, but when I play the build of the game, the set of questions is not updated between one level and another, in fact the last question made at the first level is re-proposed.

I solved the problem. I just had to clear the list of questions before moving to the next level

GUI text created during runtime is not visible

I am using the DebugConsole script to show the debug output on screen.It works perfectly but appears at the top left corner. I want it to appear inside a panel where I have created a window and a GUI text element and the script gives this option as well. I see the gui text formed as an element in the project console, but is not visible.
I do have a GUI layer
My gui text element is the direct child of a canvas
Camera is set to screen space overlay. I tried worldspace , still not visible.

Unity: Can't find UI Layout Element Max Size

In Unity UI, LayoutElement has a min, prefered and flxible size, but it do not have a max size property.
For example if I have a text1 and
layoutElement.flxibleWith = 1
layoutElement.minHeight = 19
text1 with one line txt:
But when I load text in text1 it continues spreading it height with no limits:
I have made a script:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
[ExecuteInEditMode]
[RequireComponent(typeof(LayoutElement))]
public class LayoutElementMaxSize : MonoBehaviour
{
private LayoutElement layoutElement;
private ContentSizeFitter contentSizeFitter;
private RectTransform rectransform;
public bool controllWidth;
public bool controllHeight;
public float maxHight;
public float maxWidth;
void Start()
{
layoutElement = GetComponent<LayoutElement>();
rectransform = GetComponent<RectTransform>();
}
public void Update()
{
if(rectransform.hasChanged)
{
rectransform.hasChanged = false;
if (controllHeight)
{
layoutElement.preferredHeight = -1;
layoutElement.CalculateLayoutInputHorizontal();
layoutElement.CalculateLayoutInputVertical();
if (rectransform.rect.height >= maxHight)
{
layoutElement.preferredHeight = maxHight;
}
}
if (controllWidth)
{
if (rectransform.rect.height >= maxWidth)
{
layoutElement.preferredWidth = maxWidth;
}
else
{
layoutElement.preferredWidth = -1;
}
}
}
}}
but it is not full filing my requirement plz take a look on it ..

I know this is an old question, but I was looking for something like this and I end up rewriting your class and it now works fine for me. Instead of just making another MonoBehaviour I override the LayoutElement, I also added an custom inspector to make it easy to edit it. Hope my solution could help you or anyone else that would like something like this.
