Why are these two fields not listed under my mesh renderer inspector?
(Screenshot above was sent by a friend) How would I go about getting these to show?

Is there an easy-ish way to make a text field with a list of filtered results (auto complete)? If unity has some API for it or if there's a community gist that'd be great too.
I'm currently using Ryan Hipple's searchable popup. It looks great, but you have to tell it to Show and it pops up with its own text field. (as shown in video) I'd love to just have a single text field that shows filtered results as you type.
I tried making my own popup, but have been struggling with getting it to show properly based on typing in the text field of a property drawer. Getting lots of crashes and errors 😦
If there isn't a premade solution I'd love pointers on the correct way to approach it.
From the time I've spent on the problem it seems I need to use PopupWindowContent so the GUI doesn't get clipped by the bounds of the component editor area.
The text field is drawn with a property drawer and I got stuck figuring out when to call PopupWindow.Show(...)
Before drawing the text field I have this snippet
// create and set a unique id for the text field
int controlID = EditorGUIUtility.GetControlID("PropertyID".GetHashCode(), FocusType.Keyboard, rect);
string controlName = "PropertyID" + controlID;
GUI.SetNextControlName(controlName);
// draw the text field
so that i can check if it has focus.
if it has focus, and it wasn't already showing, I show it
if (GUI.GetNameOfFocusedControl() == controlName)
{
if (!wasShowingPopup)
{
PopupWindow.Show(rect, popupContent);
...
Unfortunately this was giving me errors and always resulted in a crash eventually

hello , how can i use python in unity for editor scripting
the docs dont help

wispy delta
@onyx harness good call, that works much better! I'm also using a SearchField instead of a TextField which should make getting up/down callbacks easier.
One issue I'm running into is the popup taking focus away from the search field when it is shown.
I tried doing
PopupWindow.Show(rect, searchResults);
EditorGUIUtility.keyboardControl = searchField.searchFieldControlID;
and
PopupWindow.Show(rect, searchResults);
searchField.SetFocus();
but neither seems to work. As soon as I type a character the popup gets focus. Any ideas?
onyx harness
The focus is given to a Control
But moreover, the focus is given to the window first, then down to the control
Keep the focus on the Inspector
@wispy delta
The problem with pop-up window is, they might catch the focus anyway, otherwise they automatically close
You might have to handle your own window
wispy delta
goootcha. I'm probably doing a bunch of redundant stuff here, but the inspector still loses focus. anything look off, or should i make my own popup system @onyx harness?
if (check.changed)
{
if (!searchResults.IsOpen)
{
// Get search field window (inspector)
var window = EditorWindow.focusedWindow;
// Show popup
PopupWindow.Show(rect, searchResults);
// Refocus on search field window
window.Focus();
// Do everything that could possibly give control back to the search field :P
searchField.SetFocus();
EditorGUIUtility.hotControl = searchField.searchFieldControlID;
EditorGUIUtility.keyboardControl = searchField.searchFieldControlID;
}
}
To be honest, the system is pretty hard to grasp, or nobody have ever found a way to explain to me.
I never used hotControl or keyboardControl, I tend to prefer SetFocus ToControl
But this one needs to be handled correctly between Repaint and Layout
wispy delta
haha fair. it's all a bit convoluted. so there's a chance it'll work if i only change focus during the correct event type?
onyx harness
Yes, event type phase is very important to master when you deal with these things
wispy delta
looks like the internal PopupWindow.Init function has a giveFocus option which is hard coded to true. Perhaps making my own Show function with that exposed and a bit of reflection would make this easier
onyx harness
Yes, that's what I said, pop-up grabs the focus
Just create a window and show it as borderless
wispy delta
idk what EditorLayoutDrawer is but GUILayout and EditorGUILayout doesn't work within property drawers. it expects you to use GUI and EditorGUI within the supplied rect. if you use layout gui functions they'll be drawn below the drawers
https://forum.unity.com/threads/custom-property-drawer-in-list-layout-messed-up.563035/
@rocky flicker
rocky flicker
ah EditorLayoutDrawer from one of our libraries sorry :d
yes GUI is worked just fine thank you @wispy delta
rocky flicker
well i am listening if u willing to tell @onyx harness
onyx harness
GUILayout.BeginArea
I don't advise to use it, because sometime it implies other things, but it is convenient sometime
For speed production purpose
wispy delta
last time i tried creating an area within a drawer it was invisible. saw a couple forum posts mentioning you can't nest areas which surprised me, but you know more than me haha
onyx harness
It seems logical that you can't nest area
But it is different than what we are talking above
With BeginArea, you just plant a layout rectangle, and draw inside it
wispy delta
gotcha. i assumed an area had already began by the time the property drawer was drawn, so calling BeginArea there would be nesting an area
Begin/EndArea is the same as using (new GUILayout.AreaScope()) right?
yea it is. not sure why i was getting invisible gui. must've been some other issue
onyx harness
As you stated, PropertyDrawer is not wrapped between Begin/EndArea :)
wispy delta
liiitle bit of progress. i tried making my own window but was running into lots of issues: getting errors about antiAliasing not being valid, window not opening in the right place, not being borderless etc
i decided to not make my own window for now and made this abomination of a method to let me show a popup without it getting focus.
public static void ShowPopup (Rect activatorRect, PopupWindowContent windowContent, bool focus)
{
Object[] objectsOfTypeAll = Resources.FindObjectsOfTypeAll(typeof (PopupWindow));
if (objectsOfTypeAll != null && (uint) objectsOfTypeAll.Length > 0U)
{
PopupWindow popupWindow = objectsOfTypeAll[0] as PopupWindow;
PopupWindowContent currentContent = (PopupWindowContent)popupWindow.GetType().GetField("m_WindowContent", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(popupWindow);
if (popupWindow != null && currentContent != null && currentContent.GetType() == windowContent.GetType())
{
popupWindow.Close();
return;
}
}
if (!(bool)typeof(PopupWindow).GetMethod("ShouldShowWindow", BindingFlags.Static | BindingFlags.NonPublic).Invoke(null, new object[] {activatorRect}))
return;
PopupWindow instance = ScriptableObject.CreateInstance<PopupWindow>();
if (instance != null)
instance.GetType().GetMethod("Init", BindingFlags.NonPublic | BindingFlags.Instance).Invoke(instance, new object[] {activatorRect, windowContent, null, 1, focus });
if (Event.current != null)
GUIUtility.ExitGUI();
}
Good-ish news: the popup doesn't close immediately. It has to first gain focus for it to close when it loses focus.
There's still some kinks to work out tho. It doesn't close unless you click on and then off of the popup and a null ref is thrown from EditorWindow.Close () on recompile

I need some help with the dark arts of attributes and reflection:
I have a custom attribute named Watch. I need to get all the fields and properties with this attribute.
This tutorial https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/attributes/accessing-attributes-by-using-reflection shows how to retrieve attributes for classes but in this case I don't know the System.Type of the fields/properties.
I've tried googling for the answer but i can't find it.
public class TestClass
{
[Watch()]
int test1;
[Watch()]
int test2 { get; set; }
}
do you need the type of the field that has the attribute, or the type of the classes that have fields with the attribute?
austere adder
this attribute is only for fields and properties
I need to get a reference to the Watch attribute for every field/property so I can access the name and value of the field/property and some optional parameters of the Watch attribute
onyx harness
var fields = anyType.GetFields();
foreach (var f in fields)
{
var attrs = f.GetCustomAttributes(typeof(Watch));
if (attrs.Length > 0)
{}
}

Does anyone know how I can get mouse3 and mouse4 in a unity editor window? I saw this online: $"Current Mouse Button: {(KeyCode)Enum.Parse(typeof(KeyCode), "Mouse" + Event.current.button, true)}" but don't seem to work, anyone has an idea?
onyx harness
I dont think Unity transmit those extra buttons
But if you are on Windows, you can know it
austere adder
var fields = anyType.GetFields();
Umm I don't think looping through all the fields is a very performant option. Reflection stuff is pretty expensive but isn't there a better way?
onyx harness
It all depends on what you do
I think I can confidently say, 100% of the time, Reflection is not an issue
austere adder
I guess I can cache this
onyx harness
🙂
austere adder
but like,
if you know at compile-time all the fields with this attribute can't the compiler generate a list or something that has only the fields with this attribute?
is it technically possible?
onyx harness
yes
If you are in the Editor only
I have to say it: It won't be worth it
Even if we talk about 10k Types having some Watch
toxic timber
hey! wanted to ask how to make a dropdown in the unity inspector to show or hide float values through a C# script
wispy delta
is it an array of floats, or an enum? what's the context?
toxic timber
im coding a weapon class and wanted to have public values like ammo, reload etc. for each weapon i want in the game. However it clutters up the inspector so i wanted to know if there was a way to hide and show them through C# code
toxic timber
not before no
public string playerOneWeapon;
public string playerTwoWeapon;
public string playerThreeWeapon;
public string playerFourWeapon;
//WEAPON STATISTICS
public float ammo;
public float reloadTime;
public float timeBetweenShots;
private float shotTime;
public Sprite Sprite;
public Transform ShotPoint;
public GameObject Projectile;
//PISTOL STATISTICS
public float pistolAmmo;
public float pistolReloadTime;
public float pistolTimeBetweenShots;
public Sprite pistol;
public Transform pistolShotPoint;
public GameObject pistolProjectile;```I wanted each of these sections to be able to be hid and shown in the inspector
rather than all shown at once
wispy delta
so unity doesn't have an "easy" way to add foldouts natively without creating a custom editor. but if you're familiar with attributes you know that unity provides some to allow for quick inspector customization
you can create sliders with Range
[Range(0f, 1f)] // makes the float show up as a slider with a min of 0 and max of 1
public float someFloat;
add spaces with...Space
public Vector3 someVector;
[Space] // creates a space between these properties in the inspector
public int someInt;
and a few more
^ with that being said (sorry if you were already aware) some people have made their own attributes to handle foldout
here's the first one i found. no idea if it works
https://github.com/PixeyeHQ/InspectorFoldoutGroup
if you don't want to use an attribute i can show you how to make a custom editor that does it tho (it's a bit more work)
this repo has a lot of attributes you could use to customize the editor without write custom editors
https://github.com/dbrizov/NaughtyAttributes
toxic timber
@wispy delta Thanks! the https://github.com/PixeyeHQ/InspectorFoldoutGroup link looks like exactly what i need. I'll fiddle around with it until i get it working
@wispy delta I have downloaded the C# files
do i just drag them into the inspector to make them work or is there a special way to make it work.
wispy delta
it's all done through code
using Pixeye.Unity; // put this at the top
[Foldout("Current Weapon")]
public string playerOneWeapon, playerTwoWeapon, playerThreeWeapon, playerFourWeapon;
[Foldout("Weapon Stats")]
public float ammo, reloadTime, timeBetweenShots;
private float shotTime;
[Foldout("Weapon Stats")]
public Sprite Sprite;
[Foldout("Weapon Stats")]
public Transform ShotPoint;
[Foldout("Weapon Stats")]
public GameObject Projectile;
[Foldout("Pistol Stats")]
public float pistolAmmo, pistolReloadTime, pistolTimeBetweenShots;
[Foldout("Pistol Stats")]
public Sprite pistol;
[Foldout("Pistol Stats")]
public Transform pistolShotPoint;
[Foldout("Pistol Stats")]
public GameObject pistolProjectile;

@full vault You are looking for a splitter? Or something like that
full vault
too hard understand it
onyx harness
To make a splitter you need 2 things:
- a variable "size"
- know how to handle drag & drop
full vault
Did someone implement a simple table? If so, how? You need to be able to add / remove items. Reorder (optional) and change properties. And also change the width of the columns. In principle, all this can be done through the multicolumn tree view, but I do not understand at all how it works

Is it possible to get a reference to these two assemblies at runtime?
waxen sandal
Define reference
Assembly-CSharp contaisn all code that's outside of AsmDefs and outside the Editor directory
Editor can't be used in runtime because it's intended for Editor only code
austere adder
by runtime I mean runtime in the editor sorry
I need a reference to the Assembly class for each one of them
waxen sandal
You can but you shouldn't
waxen sandal
AppDomain.CurrentDomain.GetAssemblies gives you all of them
You can also use this https://docs.microsoft.com/en-us/dotnet/api/system.reflection.assembly.getassembly?view=netcore-3.1
austere adder
I am currently using GetAssemblies
I would like to get a reference to only these two
waxen sandal
You got a list of all of them, you can just take the ones you want
Or you can use that other method
onyx harness
You know the name, just filter the rest out
austere adder
filtering them by name is actually a great idea
onyx harness
Or you can do a smart filter
Since your attribute Watch is from your own Assembly "A".
You can filter out any Assembly not having a reference to your Assembly "A".
If you are in Assembly-CSharp-Editor, this filter might not be that efficient
austere adder
much better
austere adder
yeah
the second method doesn't really offer any advantages
I don't plan on creating other assemblies so it's fine
onyx harness
It does at some point
Imagine a world, where your Attribute Watch is being used by someone else
By dependencies handle all those cases
austere adder
Yeah that won't happen
I'm not releasing my crappy tools

filtering?

Do you have a type that you know is contained in those assemblies?

Hi, does anyone have an idea how to implement a curve editor in an inspector/custom editor. I've looked on the forums and google but so far I found no solution.
onyx harness
Handles.DrawBezier?

@vernal garden unfortunately it's all internal and was never exposed - you can use reflection but... I've at some point in the future I think there may be a revamped exposed UITK version for us if you can wait 🤞

Well lets hope so 😅 but thanks anyway!

I just ended up making my own version but as you can imagine it's fairly involved - good luck

that seems to be for in the scene view, what I'm looking for is a curve editor for in the inspector itself :/

Handles.drawbezier works

Handles works in a GUI context, therefore in Inspector

there's no floating system for GUI Editor stuff?
onyx harness

north ore
like floating divs, or a grid layout group, without having to position everything manually/static

Can I somehow wrap the elements in a container and then get the height of this container?
waxen sandal
Only available in Editor
There's also some methods like https://docs.unity3d.com/ScriptReference/GUILayoutUtility.GetLastRect.html
full vault
something doesn't work
var scope = new EditorGUILayout.VerticalScope("t");
var rect = EditorGUILayout.BeginVertical();
GUILayout.Button("a");
GUILayout.Button("a");
GUILayout.Button("a");
EditorGUILayout.EndVertical();
tab = GUILayout.Toolbar(tab, new string[] { "Object", "Bake", "Layers" });
switch (tab)
{
case 0:
m_SimpleTreeView.OnGUI(new Rect(0, rect.height, position.width, position.height));
break;
default:
break;
}
you use a scope in a using block
what you're doing is opening one and never closing it

hmm what's a good way to get the world position within a PropertyDrawer? It's for showing a popup. I'm using UITK if it makes a difference.
waxen sandal
WorldPosition of what?
split bridge
of wherever the drawer is drawn... if I grab e.g. root.worldBounds it's relative to the window it's in
waxen sandal
Ok, I'm confused. Can't help you there
split bridge
Say you have a propertydrawer that adds a VisualElement, let's call it 'root'. If you get root's worldBounds (or transform etc) it will be relative to the editor window it has been drawn in. For showing a popup I need to add the position of the editor window making it what I was calling the world/global position. So either I need a way to get the editor window from the property drawer (don't think this is possible?) or I need some utility that gets the global position.
waxen sandal
It's really confusing that they're calling it worldBounds here
waxen sandal
Nah
It's not
I googled it
Lemme check my code, I have something similar somewhere
split bridge
thnx - it's easy to do when you have a custom editor window obviously but I'm trying to build a property drawer that can be used anywhere
waxen sandal
Ah fuck, it's not the same
It's a custom window as well :/
If you've got the root element then you can try to find all EditorWindows and compare the RootVisualElement of them perhaps?
Otherwise I wouldn't know
split bridge
ok thnx - I'm just taking a look at GUIUtility.ScreenToGUIPoint
split bridge
yea, doesn't look like it.. maybe I can mix it somehow 😩
ok it's a bit hacky but I think I can use EditorWindow.focusedWindow as it's for a popup so I think the relevant window should always get focus

There is ways to get the absolute position of a coordinate
GUIUtility.ScreenToGUIPoint can help
But there are few spots in the internal API (among them, GUI clips) where you can try to get a position
@split bridge GetCurrentEditorWindow is not universal!
Since recent version and introduction of UITK, EditorWindow might not be right, and you will get a GUIView instead of a EditorWindow
Use this one in this specific case:
public class GUIViewWrapper
{
private static Type GUIView = AssemblyVerifier.TryGetType(typeof(Editor).Assembly, "UnityEditor.GUIView");
private static MethodInfo RepaintMethod = AssemblyVerifier.TryGetMethod(GUIView, "Repaint", BindingFlags.Instance | BindingFlags.Public);
public object target;
public GUIViewWrapper(object target)
{
this.target = target;
}
public void Repaint()

GUIViewWrapper.RepaintMethod.Invoke(this.target, null);

{
initializeCurrentEditorWindowMetadata = true;
LazyInitializeCurrentEditorWindowMetadata();
}
if (current == null)
return null;
return new GUIViewWrapper(current.GetValue(null, null));

(The toolbar is a GUIView for example)

I'll stick with focusedWindow for now as it appears to work fine in my tests with e.g. multiple inspector windows but I'll keep the above in mind should I encounter any issues, thanks.
onyx harness
focusedWindow is unfortunately not good
split bridge
when does it fail?
onyx harness
as it says, it gives you the focused window
If your PD is drawing independently, it wont work
split bridge
as I mentioned, it's for a custom popup menu - so clicking on the menu gives the inspector/window focus
onyx harness
Now, if you rely on a click event, yeah it should work
split bridge
yea - there may be edge cases I haven't thought of / encountered yet
but I'd rather used focusedWindow over a bunch of reflection if it does the job

Is there a way to use UIElements for a custom inspector?
or are they only for editor windows
visual stag
Yes, the custom inspector docs gives examples
digital spoke
I want to make something like this with UIElements but I'm a tad confused on how. I've tried using a toolbar and a toolbar toggle but they don't seem to be what I want.
visual stag
you'll find many controls do not exist and you have to make your own
luckily that is way easier
can even do it through the UI Builder
digital spoke
yeah that's what I'm using, UI Builder.
where can I read up on creating my own controls?
visual stag
nowhere yet really, I would just crudely do it with two buttons with different styles
digital spoke
would there be an easy way to have it so when one is on the other is off and it will switch between those two states based on which one is on?
visual stag
the lazy way is to set it up in code in your editor
the complex way is to make your own field (with a UxmlFactory and UxmlTraits)
digital spoke
seems like the best way is just to go back to using GUILayouts tbh
https://docs.unity3d.com/ScriptReference/GUILayout.Toolbar.html since this is essentially what I want
is it a good idea to have a 'hybrid' editor of GUILayouts and UIElements or are you meant to just use 1 or the other
visual stag
you can use IMGUIContainers to nest IMGUI stuff
I tend to not bother unless it's a complex field
There are probably others that know more about UIToolkit that can help - I have an dual-toggle with label thing I've made for a runtime

But it'll have USS specific to me
it might help

Is it a good idea to use a script you're making a custom inspector for hold data for stuff like which toolbar item is selected so it doesn't get reset if you deselect and reselect the object? Or should I just use editorprefs for this?

does anyone know how to add custom buttons in the toolbar? I could've sworn it was a relatively new feature that unity was talking about, I don't know if it's only available in unity 2019+ or not. googling didn't get me anywhere
waxen sandal
If that part is UIToolkit then it should be fairly easy
Only things I've heard is people adding things in a hacky way
lethal sage
Is there a way I can hide this part of the inspector only when I'm viewing the Enemy class in the context of a ScriptableObject? I want to be able to see it when I'm viewing the Enemy class elsewhere but for this specific case it should be hidden as it is a runtime-only class and I use the other Equipment field (at the bottom) when setting up the enemy in ScriptableObject form.
Pretty much if this worked it would be perfect:
DrawPropertiesExcluding(serializedObject, "enemy.equipment");
but it only works for the properties that are direct children of the editor, so I have to do
DrawPropertiesExcluding(serializedObject, "enemy");
and then somehow re-draw the whole enemy class bar the equipment field in it
waxen sandal
That's not a default Unity method
It shouldn't be too hard to draw things manually though
Just use an Expander with the IsExpanded property of the Enemy serializedproperty and then just find the childs you want to draw and use propertyfiel
lethal sage
Doesn't PropertyField have very limited uses e.g. it doesn't work on arrays or anything that can be expanded?
waxen sandal
No?
You can also extend whatever is implemeting DrawPropertiesExcluding to support child elements
lethal sage
I'm using the newest stable 2020
lethal sage
yeah
waxen sandal
Weird
lethal sage
Reason I'm not sure about PropertyField is because this simple rename attribute, for example, doesn't work on arrays (it makes them unexpandable)
EditorGUI.PropertyField(position, property, new GUIContent((attribute as RenameAttribute).DisplayName));
Is there a function to just draw a property the default way and I can loop through the properties and skip the equipment one?
lethal sage
hm, maybe it's arrays that are weird rather than PropertyField
waxen sandal
That literally finds the correct property drawer and draws it
waxen sandal
If you really want you can check whether it's an array
And do your own array drawer thing
And then use propertyfield for every entry
lethal sage
yeah that's what the examples I saw did, seems like reinventing the wheel but at least it's possible
also is there a way to loop over all child properties of a property? I'm seeing CountInProperty() to get the amount of children but idk how to access them without knowing their names
GetEnumerator?
nevermind, seems like a foreach loop works as with transform as it's enumerable
waxen sandal
GetIterator works as well
lethal sage
it seems that iterating over the children of a property breaks FindPropertyRelative
this log:
Debug.Log(enemy.FindPropertyRelative("equipment"));
returns non-null before the foreach, returns null during the foreach, and returns null after the foreach
waxen sandal
I'm not sure how supported foreaching over a serializedproperty is
If you do GetIterator you get a new one
And it changes the current instance
lethal sage
that should be good, ty
GetIterator doesn't seem to exist so I'll have to use an enumerator
actually that's the same thing lol
lethal sage
Nice, I got it working, ty 🙂

You should be able to use SerializeReference for polymorphic serialization
Then write your own editor to add/remove elements

Is SerializeReference ready to work with in 2020.1? I tried it, and it only kind of worked half ass. Even the example given on the docs wasn't working properly

So I am assigning unity event listeners through the editor
UnityEventTools.RegisterVoidPersistentListener(tracker.CollisionStarted, 2, notifier.DoExtract);
But it isn't using the dynamic version of it.
How do I fix this?
waxen sandal
Make sure that the last parameter points to the right DoExtract call
fathom glen
waxen sandal
Then what's that other DoExtract?
fathom glen
Oooh it might be due to inheritance then or something.
Its VRTK stuff
No idea where it is coming from xD
waxen sandal
Are there overloads?
fathom glen
yes
Is there a way to skip the overload then?
There is only 1 overload
If not, I can work around it
waxen sandal
But if there's an overload it doesn't match the signature of the event right?
fathom glen
Its a void event. I think the overloaded is listed as a static one in the picture above and the base one is listed as dynamic
Maybe if I cast object to it's base class and then call DoExtract
waxen sandal
Idk what dynamic event data is
Does that let you set parameters manually in the inspector?
fathom glen
Dynamic automatically passes any data to the function specified
Static uses data specified in the inspector
waxen sandal
I'm assuming UnityEventTools.AddPersistentListener gives you the same result?
fathom glen
Ye
waxen sandal
And that DoExtract method has the correct parameters right?
fathom glen
It doesn't have any parameters
waxen sandal
And your event doesn't either?
fathom glen
It has EventData
I can set it to use the dynamic one in the inspector
It is just not possible through code
Due to the way the VRTK code is setup
Virtual Reality ToolKit
waxen sandal
Can you show me DoExtract?
fathom glen
Where do I enable it?
waxen sandal
Help > About Unity
Then type internal
You'll get some extra goodies
Then set your event to whatever way you want it to be
And enable debug internal mode in your inspector
Now you can expand your persistent calls and view what data actually needs to be set
Take a screenshot or something of that information
And then use SerializedProperties to set the same data for your method call
fathom glen
Ok
the difference between the two is
this
The dymanic one is set to Event Defined
The other one to void
waxen sandal
Okay, now you can use serializedproperties to go to that property and set it to Void after you use UnityEventTools.RegisterVoidPersistentListener
fathom glen
UnityEventTools.AddPersistentListener gives you the same result? Apparently it doesn't give same result. Should have double checked.
I have been playing around with this for quite some time, must have confused it
Thank you though!

Yes

Is there a way to update something in a script when another component attached to the same object changes in the editor? OnValidate doesn't seem to work for this purpose
waxen sandal
OnValidate on the other component should trigger just fine
Then you can find the other script
digital spoke
well it doesn't do anything when I change the grid component attached to the same object
waxen sandal
No no, you need OnValidate on the object that is changing
Not the one you want to change
digital spoke
well then that's impossible since I can't modify unity's source code lol
waxen sandal
Ah
You can also use ExecuteInEditMode and manually check if it has changed
Or use a custom editor that does something similar
Or just update it in awake

Hi all. Im trying to work with both Asmdef and #if platform compilation, and to be honest im not sure how this can be done
A class in my Core.asmdef used to use #if UNITY_EDITOR to access some AbcEditor class.
But now i also made Editor.asmdef and how can my Core classes still "use" AbcEditor stuff? Or this is just impossible to workaround and i need to restructure some stuff?
waxen sandal
I'm actually not sure if you're allowed to have a reference in your AsmDef to an editor only AsmDef
I would assume so and it'll just get stripped
split bridge
Anyone know how of a validation utility method or where to find docs on valid characters for asset names? i.e. they can't contain ? and I assume many other special chars

Yep, it doesnt allow me to do that. That's why i need to restructure things i guess

Should PropertyDrawers be put in Editor.asmdef?
Bcoz if i do, my Core.asm class that uses the property will complain on build
I have to do this everywhere?
#if UNITY_EDITOR
[MyProperty]
#endif
bool someVar;
You need to put them in either a directory called Editor or in a AsmDef that's marked as editor only
real ivy
Yes but, the someVar is inside a Core.asmdef
If i put the PropertyDrawer script in Editor, then [MyProperty] wont even be accessible at all from Core
real ivy
Thats the other way around
waxen sandal
And you can use serializedproperty just fine
Editor knows about core, core doesn't know about editor
real ivy
Core will need reference to Editor (bcoz the PropertyDrawer is defined in Editor)
waxen sandal
No?
real ivy
And [MyProperty] is used somewhere in Core
Core will need reference to Editor (bcoz the PropertyDrawer is defined in Editor)
@real ivy Im saying this if i follow what u said, then this has to be done
waxen sandal
So you have an attribute right?
You define that attribute in Core
Then in Editor you have a reference to Core
And your PropertyDrawer with the CustomPropertyDrawer(typeof(MyPropertyAttribute)) as attribute
real ivy
"Define that attribute in Core" means [MyProperty] bool someVar;, right?
waxen sandal
Whatever the definition of MyProperty is
Probably public class MyPropertyAttribute : PropertyAttribute {}
real ivy
Yes and this is used somewhere in a class in Core
And the definition
[CustomPropertyDrawer(typeof(EnumMaskAttribute))]
public class EnumMaskPropertyDrawer : PropertyDrawer```
If i put this in Editor.asm, then the [EnumMask] can't be used in Core bcoz it doesnt exist[CustomPropertyDrawer(typeof(EnumMaskAttribute))] so this goes somewhere in Core? Where exactly?
waxen sandal
No
real ivy
Shouldnt those 2 lines be directly together?
real ivy
Oooh found it
waxen sandal
[CustomPropertyDrawer(typeof(EnumMaskAttribute))]
public class EnumMaskPropertyDrawer : PropertyDrawer```Goes in Editor
real ivy
Yea this was in the same script. That and i never wrote Attribute stuff from scratch myself..

Can't stop, as long as the dictionary is not serializable

Do OnBeforeSerialize/OnAfterDeserialize get called before or after functions like OnEnable()/Awake
onyx harness
Yes
digital spoke
well for reason my dictionary keeps getting cleared even when using the example unity shows on their wiki
public void OnBeforeSerialize()
{
positions.Clear();
data.Clear();
foreach (var kvp in tiles)
{
positions.Add(kvp.Key);
data.Add(kvp.Value);
}
}
public void OnAfterDeserialize()
{
tiles = new Dictionary<Vector3Int, TileData>();
for (int i = 0; i != System.Math.Min(positions.Count, data.Count); i++)
tiles.Add(positions[i], data[i]);
}
https://docs.unity3d.com/ScriptReference/ISerializationCallbackReceiver.html
it's pretty much exactly the same as the example here albeit my variable names are different
TileData is serializable (it's just a class that holds a gameobject value and two int values and has the attribute [System.Serializable] )
and I assume Vector3Int is serializable

Hello. I'd like to make a hue curve editor. Something like a CurveField with an image background (showing the hue image). What would be a good approach for this? It seems like I may have to use an immediate mode element, but I'm not keen on reimplementing the CurveField just to get an image background. Any ideas?
visual stag
So, like a gradient field, but instead of using a colour picker you only have one axis and it's represented as a curve?
quiet swift
Yes. This image with a curve on top, to reprsent how much of hue will be used.
(except, not using the numbers)
Something like the hue-vs-hue properties in post-processing stack v2.
Maybe I could just go and repurpose them...

I would probably look at how the post processing colour curves have done it

Well @visual stag I got something going using CurveEditor from PPv2! Needs some work, but happy to get this going.

I'm going to use it for light dropoff. It's meant for underwater so want to filter out the red side of the spectrum first.
Not sure if it's the right approach, but it seemed the easiest way to get there!
The CurveEditor was really easy to use, with no dependencies. The pain was the custom pass drawer. It has a bug that causes it to reinstatiate the drawer every refresh and dispose the SerialiedProperty. Made it hard to keep state.
visual stag
Good to know about the curve editor, I think I've looked for one in the past and it hasn't been fun

Does anyone know how can I, given a Textute2D with multiple sprites defined in it, can get an array/list/collect of all the Sprites inside it, with only a reference to a Texture2D object?

I was really looking forward to using it, but it made my Unity so unstable that I've had to export the project I'm working on, take out the github plugin, and re-import the project. It seems like it causes Unity to freeze almost every time I tab back into it while coding :/
Though, it could be because I had previously hooked that project up with Collab before I found the github plugin. I dunno though.

Does anybody know how I can update a Material that has been changed via custom inspector? I am updating a blend value in EditorApplication.update but it only sporadically changes
waxen sandal
Are you using serializedproperties or registering it with undo?
thin fossil
no I am using the direct approach:
this.TargetMaterial.SetFloat(Blend1, t);
waxen sandal
Define: sporadically changes
thin fossil
it does not blend smoothly but jumps in different time intervals. I am also changing the textures that are blended though. so it could be that it does not update the blend values at all and only updates when I switch textures
I am blending between a number of frames based on the current time. This is currently blending between frame 1 and 2 at 0.82 blend value.
If I press play the slider and the values in the inspector smoothly interpolate but the blend animation of the material seems to jump from frame to frame
🤔 Well thats interesting. If I set the _Blend variable up as a property in the Shader it works:
_Blend ("Blend", Range(0,1)) = 0
But I would like to avoid this as this will always set the material dirty and produce version control conflicts.
So I guess my problem is how to update a shader variable that is not a property
thin fossil
I removed the shader property and it still works

Yes.

however when it's instantiated, it's replaced for no reason (I never write to the reference. I only read from it)
onyx harness
Define "instantiated" please
onyx harness
however when it's instantiated, it's replaced for no reason (I never write to the reference. I only read from it)
@digital spoke I would say because the ref is itself, so when you place it on the scene, the ref remains itself
digital spoke
so what's an easy way to fix that?
the only thing I can think of is storing all of the autotiling rules in a scriptable object?
onyx harness
I would say, get the prefab from the GameObject
Then instantiate it again from the prefab, not the Gameobject
There is API for that
digital spoke
GameObject tile = PrefabUtility.InstantiatePrefab(PrefabUtility.GetPrefabInstanceHandle(newTile)) as GameObject; // Returns null if newTile is a scene instance of the prefab we're trying to instantiate from it.
``` Like this?Just prints this. Doesn't highlight anything when selected.
onyx harness
You are not using the right API then
digital spoke
seems that GetCorrespondingObjectFromOriginalSource might've worked? Highlights the correct object.
onyx harness
Should do the job
digital spoke
well apart from the fact it seems to erase all references to gameobjects when it's instantiated
GameObject basePrefab = PrefabUtility.GetCorrespondingObjectFromOriginalSource(newTile);
Debug.Log(basePrefab, basePrefab); //Confirms it's the actual prefab, rather than the scene instance of it.
GameObject tile = PrefabUtility.InstantiatePrefab(basePrefab) as GameObject;
seems to erase all references from the entire script
onyx harness
I just feel that your design is fundamentally wrong
digital spoke
i know
but i need to use prefabs otherwise the whole purpose of this tool becomes pointless. I could just switch prefabs with meshes and just change the mesh of objects but prefabs let me modify tiles and see them change on the map
and no matter how I try to make the autotiling system work with prefabs, at some point I have to instantiate it, causing the problem.

problem with references becoming null seems to be due to the fact the script on the prefab is technically referencing itself?

does anyone know lots about having nested serializedObject.Update() and ApplyModifiedProperties() ? I've got a case where it kinda just seems to, not work
I have some properties where I need to handle changed values in a specific way on a per-object basis (rather than using the serializedObject to modify/set all selected objects properties to the same value)
long story short - I have a field for a position, and another field for space. when switching space from world to local, or vice versa, I want to compensate for this so that the coordinates remain in the same place
so basically - on edit space -> update coordinates for each selected thing (if it changed space)
normally I could just set the property value, but in this case it could be different for all the different objects
I thought iterating through all the serialized objects of the individual types, assigning the new coordinates if needed, and then applying it, would work
but it looks like the values never actually change - they are changed on the line right after I assign, but, when all is said and done the values are unchanged
split bridge
@blissful burrow are you trying to modify the serializedObject and the related Unity.Object in the same update as it were?
blissful burrow
I'm only touching serialized properties! so probably only the serialized side of things
I iterate through all selected objects, get their serialized object, and serialized properties, and modify them if needed
split bridge
ah.. so just because you mentioned .Update() and in case you didn't realise (I didn't at first), it updates the serialized object representation from the Object so you just might not need that in your case? Sorry if this is obvious stuff you know already.
blissful burrow
but I suspect it might be an issue of me modifying the "master" serialized object, that like, targets multiple objects with a single serialized object outside of the scope of those
onyx harness
@digital spoke Yesterday you pointed to a link where the guy said a fine solution, go through a SO
blissful burrow
@split bridge ah this is all in a custom editor
split bridge
sure
blissful burrow
basically this is my structure:
OnInspectorGUI{
so.Update();
so.propertyField A
so.propertyField B
// etc
if field A changed {
foreach( targeted serialized object tso ){
tso.Update();
tso.property = new value
tso.ApplyModified();
}
}
so.ApplyModified();
}
I suspect the issue might be that the last so.ApplyModified overrides all the individually edited ones maybe?
split bridge
basically I don't think you need to call .Update unless your underlying object that your so represents has changed via means other than you changing so values.. does that make sense?
blissful burrow
yeah might be true! not sure if that's the issue though
split bridge
var bob;
bob.property = 10;
SerializedObject bobSO = new SerializedObject(bob);
bobSO.property = new value
bobSO.Update() // bobSO.property now updated value to be 10 again
yea, totally might not be your issue.. but if those are nested, I wonder
graceful gorge
Wouldn't calling Update between serialization overwrite your changes ? What happens if you just apply the property once at the end of all the operation ? Without Update or the applyproperty in the loop. If the changes are dependent on each other you might have to just manipulate the object directly (not fun)
blissful burrow
removing the last so.ApplyModified makes that part work, testing removing the nested ones now
split bridge
:/ I think you want to keep the ApplyModified and remove the .Update?
steady crest
can we modify the content of this window?
blissful burrow
@split bridge yeah of course, just wanted to see if the specific parts that had the nesting would work if I removed it
which it does
so it seems like the last applyModified is overwriting whatever the nested stuff did
removing the inner update/apply makes it not work either, the data doesn't update
graceful gorge
Could you put the actual customInspector in a pastebin ?
graceful gorge
Just the inspector stuff, the rest shouldn't matter that much (it's mostly space transformations right ?)
blissful burrow
and lots of other fields but
graceful gorge
(Also we're not judging :p, the unity inspector stuff is hot garbage no matter what)
split bridge
speak for yourself @graceful gorge 😄 jks
blissful burrow
this is the inner function for the space field: https://pastebin.com/sAp0efGi
graceful gorge
Wait do some field serialize and other don't ?
blissful burrow
it's more like, my act of wanting to change some of the selected objects fields depending on if they were switched from world to local or local to world, doesn't seem to save in the end
the other things serialize fine, where I use the usual property fields and whatnot
regal jasper
@blissful burrow
You should call so.Update always, the issue is calling so.ApplyModified() without checking if there was changes at all:
OnInspectorGUI{
so.Update();
using (var soScope = new EditorGUI.ChangeCheckScope()) // this
{
so.propertyField A
so.propertyField B
// etc
if field A changed {
foreach( targeted serialized object tso ){
tso.Update();
using (var tsoScope = new EditorGUI.ChangeCheckScope()) // this
{
tso.property = new value
if (tsoScope.changed) // this
tso.ApplyModified();
}
}
}
if (soScope.changed) // this
so.ApplyModified();
}
}
on a high level, this is what I want to do:
if space changed
foreach selected object
update coordinates
you don't have to check for changes when applying it
regal jasper
if you don't, you will just apply the last detected values for all instances, but you want to each instance to keep the value unless there was a modification that affect all at once
so, if you don't want multi-edit support, you don't need to check, but for multi-edit you always want to check
blissful burrow
to some extent it's both - you change the space property on all selected objects, which I do want to update on all of them, but the coordinate override is only needed on the ones that actually had it changed
(I've never had issues with multiselection using ApplyModifiedProperties without checking for changes before)
waxen sandal
regal jasper
to some extent it's both - you change the space property on all selected objects, which I do want to update on all of them, but the coordinate override is only needed on the ones that actually had it changed
@blissful burrow this is exactly what will happen if you use the ChangeCheckScope
blissful burrow
so, are you saying it should work if I just use change checking for the outer scope?
regal jasper
if I got your issue right, yes
blissful burrow
that broke everything instead, oh no
no values update now, even the ones that used to work that are unrelated to the nested shenanigans
steady crest
ah, just couldnt find what it was called I suppose
blissful burrow
actually wait might be my fault
yeah the not working at all was my fault
but having the change check in the outer scope (and the inner scope that I had before) made no difference, it's broken in the same way
bleh, why did this turn out so complex
strong "I just want to..." energy
waxen sandal
That's a lot of editor scripting in my experience
Especially package manager and uitoolkit

onyx harness
If you don't care about Undo, just play with Object directly
blissful burrow
I do care a lot about undo
waxen sandal
The api to install and stuff is atrocious
blissful burrow
and I know I can directly modify objects
waxen sandal
They pretend it's async but it's not
Queueing 2 actions at the same time has no deterministic outcome
There is no event when it's completed
So you have to poll it in update
To a property that calls the native later to check whether its done
Native layer
blissful burrow
alright I guess I might have to go the Undo.RecordObject route
digital spoke
with my autotiling system, it seems storing the autotile rule data on a scriptable object instead of storing directly on the script fixes the problem of references becoming null
it seems that it's because the script on the prefab is referencing that prefab (self-reference) which might be causing unity to not understand what to do
graceful gorge
@blissful burrow No precise idea what is causing this, and no workaround that would keep undo. Can the "fill" objects be set as dirty somehow ?
blissful burrow
mmmaybe
onyx harness
@blissful burrow
You should call so.Update always, the issue is calling so.ApplyModified() without checking if there was changes at all:
OnInspectorGUI{
so.Update();
using (var soScope = new EditorGUI.ChangeCheckScope()) // this
{
so.propertyField A
if field A changed {
foreach( targeted serialized object tso ){
using (var tsoScope = new EditorGUI.ChangeCheckScope()) // this
{
tso.property = new value
if (tsoScope.changed) // this
tso.ApplyModified();
}
}
}
if (soScope.changed) so.Apply // this
@regal jasper I would put the 2nd Apply() before the fieldA changed stuff.
blissful burrow
yeah, I think it might work if I do that
but that gets complicated for, reasons~
(my code has some layers)
regal jasper
@onyx harness true, didn't noticed that
blissful burrow
the reason things get complicated is that the second so.Apply is a function in the base type that does more than just that, it has to update things (mesh data, material properties etc) depending on what you changed, so this means I'd have to be able to introduce exceptions to how it works
I really wish the serialized object that the editor targets would also detect changes of the individual serialized objects you had selected
anyway record object time~
graceful gorge
Good luck :/
blissful burrow
thanks anyway all!
onyx harness
I really wish the serialized object that the editor targets would also detect changes of the individual serialized objects you had selected
We all wished a lot of things about Unity's way of signalling events...
blissful burrow
oh gosh
it works now but I feel like it shouldn't
this is really cursed
I basically wrapped every individual serialized property field in their own Update()/Apply() pair
onyx harness
I really feel going through Objects and handle Undo "manually" was much quicker and less headache in your case
blissful burrow
except then the new headache is the fact that it has to handle objects of different types
so then I'd need to use reflection and/or restructure all my stuff
but it works now so yay!
onyx harness
Don't you have to do that anyway with SO if you change any structure?
blissful burrow
what do you mean by change structure?
onyx harness
objects of different types
blissful burrow
as long as the serialized properties use the same path it's fine
which they would
onyx harness
Basically, the same with Reflection, just the way of doing diverges
blissful burrow
well, the way of doing it is done by Unity instead of me with reflection
onyx harness
But yeah, it works, that's the main point 🙂
blissful burrow
I think the reason it works now is that the parent serialized object has its properties applied before the nested structure shenanigans happen
so the outer object won't touch those inner ones
onyx harness
Basically what I stated here?
I would put the 2nd Apply() before the fieldA changed stuff.
blissful burrow
yeah sort of, except the second apply is still there, haha
(just moving it gets complicated for reasons mentioned above)
blissful burrow
what a fill~ things work
blissful burrow
yeah
onyx harness
Is there a specific reason to use a CustomEditor over PropertyDrawer for your "Fill square"?
blissful burrow
I generally never use property drawers (in custom editors)! so, preference I suppose
onyx harness
Fair enough

Need help creating a tool system for my 3D tilemap. Currently, there's only one tool, the paint brush tool. I want to create an API that lets me create new tools with custom functions (eg: rectangle tool).

public Texture2D icon;
public abstract void Paint(GameObject tile, Material[] materials,Bounds paintArea);

Hi, I want to replace the behaviour of ctrl+d on a gameobject. I wrote my own custom method for that(When I duplicate a gameobject I like having something1, something2,. instead of something(1), and something(2),). I have 3 issues with that :
- If I ctrl+d a prefab it does not stay a prefab and I don't really know
how to create a prefab(Instantiate() does not work for this) - If I hit ctrl+d on a gameobject multiple times(ex : something) I will
only get something1. I would need a counter to increment but it is a static function,
and c# does not support static vars in a static function.
cs [MenuItem("GameObject/Duplicate %d", false, priority = -100)] private static void DuplicateGameObject() { Debug.Log("Ctrl D pressed on a GameObject"); foreach (GameObject gameObject in Selection.gameObjects) { string name = gameObject.name; int number = 0,i = name.Length - 1; while (i >= 0) { bool isNumeric = int.TryParse(name.Substring(i), out var numberTest); if (!isNumeric) break; number = numberTest; i--; } number++; string duplicatedName = name.Substring(0,i + 1) + number; Transform parent = gameObject.transform.parent; GameObject duplicatedGameObject = Instantiate(gameObject, parent, true); duplicatedGameObject.name = duplicatedName; } }

@flint vapor just so you're aware, as of 2020.1 Unity finally added preferences for numbering schemes here:
they still don't have your preference in there though (only (1), .1 or _1)

@flint vapor it was just a first google result - you could use something like EditorApplication.hierarchyWindowImteOnGUI according to my second google (https://answers.unity.com/questions/1274030/unity-duplicate-event.html) if it's that important to you to not have an underscore 🙂

it doesn't require an explanation, you could use a tokenizing text box and let the user push around the insertion tokens
if you only did a string it does require some explanation, but a tooltip explanation should be enough for anyone using something as complex as unity, even as a non programmer

Hello 🙂 , I'm looking for some resources on how to make scene gizmos/handles moveable. Let's say I have a sphere which is drawn like Gizmos.DrawSphere() or a rectangle drawn with Handles.DrawSolidRectangleWithOutline I now want to be able to drag that sphere or rectangle around with the normal transform gizmos for example, and get the new position of the gizmo as output. Could anyone possibly point me in the right direction or to some resources? Maybe it's just me but I can't find much regrading this...
Thank you!
