Hey guys,
I have 2 questions. Is there any ways to strict array size in inspector ? without writing new PropertyDrawer. Like the array size should be always 10 and can't change the size in inspector.
Another one is, how can I check if someone wants to use my PropertyAttribute with array field ? (Like showing a warning next to that field name in inspector when array field uses that specific PropertyAttribute)
visual stag
You could use OnValidate to ensure that the size is correct
distant atlas
anyone know what the name of this built-in style is? also, isn't there a way to get the built-in styles apart from UnityEditor.EditorStyles, I remember there's a method for it but I can't recall the name
onyx harness
@distant atlas breadcrumb
distant atlas
ok thanks
onyx harness
Google "Unity editor styles viewer"
@smoky radish In your SP you have propertyType. I use it to know if my drawer is targeting the right type.
And about your warning, you should look at property decorators.

Hey everyone
I'm trying to write my own behavior tree editor window that works similar to the Animator window with nodes and connections
I have the window created and the graphing part done, but I'm struggling with loading the graph based on the selected asset
if anyone could point me in a direction for a tutorial or documentation on this stuff that would be great
I'm thinking about using a simple json file to store and load the tree
waxen sandal
I'd just use a scriptable object
neat shadow
I think I'll go that route
I think if I use a scriptable object I can pull it in through Selection.activeObject?
brittle cosmos
I put this in general, but maybe it should rather be here ---
So I'm clearing stuff from the editor like so:
for(int i = content.childCount - 1; i >= 0; i--)
DestroyImmediate(content.GetChild(i).gameObject);
Suddenly I'm getting the error Destroy may not be called from edit mode! Use DestroyImmediate instead.
Which doesn't make any sense
onyx harness
It is common to not use Destroy but DestroyImmediate during editor time.
brittle cosmos
That's the problem, I'm clearly using DestroyImmediate, but still getting an error about using Destroy
onyx harness
Which version of Unity are you using?
One of the comment states "You are strongly recommended to use Destroy"
And I am using U2017.4
brittle cosmos
2019.1.3
As I understood DestroyImmediate is used during editor, and Destroy for in-game
onyx harness
Reproduce the bug in an empty project and report the bug
brittle cosmos
Yeah I guess I could try. Not sure I can though, it was working fine, then just suddenly started happening.
distant atlas
@brittle cosmos check the callstack the next time you get that error, so you can see what line of code from your script caused it
brittle cosmos
It's literally on the line DestroyImmediate(content.GetChild(i).gameObject);
That's it
Oh actually above that it in the call stack it has UnityEngine.Object:DestroyImmediate(Object)
But that doesn't really make much more sense.
distant atlas
hmm weird. your script is in an Editor folder, right?
brittle cosmos
Ah well I have an editor script for a MonoBehaviour (in an Editor folder), which show a button that calls a function on its MonoBehaviour
distant atlas
I mean the script that calls DestroyImmediate, it's in an Editor folder? and is it in an Editor class, or an EditorWindow class?
brittle cosmos
It's an Editor class for a MonoBehaviour. But the monobehaviour which actually calls DestroyImmediate is not in an editor folder
The Editor is in an Editor folder, which is inside another folder, but as I understand it's ok to have those in subfolders.
I guess an import point is that despite getting this error, the objects are actually being destroyed

this is just an spontaneous thought but can you use DOTS in editor scripts?

I really feel this is very edge case X)
In which world would I need supa power in the editor world
split bridge
I'm working on a tween library - being able to preview at edit-time would be super powerful. Unfortunately it's not really supported at the moment. You can create a World at edit time but afaik trying to get systems to run in the same way as at playtime is v difficult.
wispy delta
@split bridge I agree it might not be the easiest thing, but if you are updating tweens yourself you could try plugging in to the EditorApplication.update delegate. You could also look at the Editor Coroutines package.
split bridge
thanks @wispy delta - sorry this is specifically with ECS (which is what I took SWS's question to be about) - previously had no luck at updating a series of systems at edit-time
wispy delta
Ah I gotcha @split bridge
@distant atlas I don't think know if you can do ECS in the Editor but you can definitely run jobs
wispy delta
There might be some edge case but yea idk why you'd wanna do that either. Jobs are very useful for expensive operations tho
I guess a good reason is if you want to preview something that is normally done at runtime
split bridge
I agree it's not that common but the reason I commented was to provide an example - being able to design & preview a complex tween at edit-time using the exact same systems as at runtime (to ensure parity) would be very useful
Other uses include things such as timeline workflows

distant atlas
@wispy delta sorry I didn't realize I got replies. when I said DOTS I guess I was really just referring to jobs, so I guess that answers it then. in one of my prototypes I'm doing some heavy number crunching that I want to cache to a file instead of having it computed in runtime, but I wanted to take advantage of multicores to make it even faster
wispy delta
@distant atlas Coolio. Yea jobs behave exactly the same way in the editor as they do at runtime. The only minor annoyance is working with native arrays/collections. You have to dispose them whenever unity compiles or switches between play mode or edit mode. If the native arrays are stored on monobehaviours you can just add the ExecuteAlways attribute and allocate in OnEnable and deallocate in OnDisable that'll prevent any leaks from playmode changes or recompiling
distant atlas
alright, thanks for the tip!
crystal laurel
Might be a bit of a dumb question, but I've got an array as part of an inspector script, that I populate during OnEnable() (Well, run a function to populate it during OnEnable) - it's then displayed as a pop up - this works (mostly) fine when running in edit mode, however, when I enter play mode, I get a lot of NullReferenceExceptions, and the pop up doesn't display within the inspector. I've tried serialising the array w/ [SerializeObject], along with making it a public object. Only thing I've yet to try is setting it as dirty. But I'm not sure if that'll work?
Quite confused as to how to resolve this, and fix it!
onyx harness
What is null?
crystal laurel
The array, it seems. The null reference exception comes from line of code I use to set up the pop up/dropdown: SelectedIndex = EditorGUILayout.Popup("Voice to use: ", SelectedIndex, SpeechNameArray);
onyx harness
Just check why SpeedNameArray is corrupted
sterile spire
is SpeechNameArray a static or a local variable on your editor script?
you could try making it static (if it is not), hope it works!... and don't forget to initialize it OnEnable

I'm trying to create an Importer for Lego LDraw files. They are essentially mesh files but can contain references to other LDraw files. So the 2x4 brick LDraw file can use the Box LDraw file and Stud LDraw file to create it's mesh. I've tried creating:
- ScriptableObject for the LDraw file
- ScriptedImporter for importing the LDraw files
- AssetPostprocessor which combines the mesh created directly from the file with the meshes in the files that are being referenced.
The AssetPostprocessor then sets completedMesh in the LDraw scriptable object. This seemed to be working, but sometimes I had to re-import the files to get completedMesh to be created. After researching it seems like I may be doing this wrong, and that the LDraw asset cannot be changed after being imported, even in the post processor. Is that right?
wispy delta
How are you setting the values from the editor?

ok, i'm still not very good at unity, just finishin up the 2D platformer tutorial, but i want some help with a piece of code i'm tinkering with
all that I am trying to do is delete some objects once they have fallen out of the general game area
my idea was simply to make them delete themselves after going below a Y value on the map
this is what I have so far:
hang on has the code appeared yet?
because i can't see it on my end

They’re just deleting themselves immediately
Actually let me double check some things

It just mean your transform is low at start
arctic cove
@onyx harness actually no I figured it out
I used gameobject which caused ALL of the objects to be destroyed
Sorry I should probably take this to general programming

Is there a good way to calculate rects for EditorGUI.PropertyField?
eg. placing two properties under each other, is there some built in stuff to calculate offsets, spacing, etc.?
Well I found EditorGUIUtility.singleLineHeight and EditorGUIUtility.standardVerticalSpacing
I guess you just have to do the rest manually?
brittle cosmos
Nice. Getting ReorderableList to work.
Editor script is useful, and pretty powerful, but seems kind of inaccessible.
It's mostly in the documentation but I haven't found it very useful. And other information in the internet is scattered.
Maybe that's just me though?
onyx harness
A lot of try and try and search
@brittle cosmos have you tried GUILayoutUtility.GetRect?
brittle cosmos
I have not. Thank you, that looks useful
onyx harness
This method is to reserve a space in the GUI layout world.
lone quarry
So... if I try to save a scriptableObject, should I use EditorUtility.SetDirty? In the Documentation it said that this function should be avoided
*in an Editor window
onyx harness
I've search for the word window, there is none
lone quarry
what?
onyx harness
It doesnt say to avoid it 🤔
lone quarry
well it says "The only remaining use (which is used rarely) happens if a non-scene object is modified with other means and with no added undo entry. Use of this approach is unlikely."
onyx harness
Rare does not mean to avoid.
lone quarry
so... should I use it then?
onyx harness
I am misreading unlikely maybe XD
lone quarry
😄
regal jasper
@lone quarry basically you can avoid using that by using SerializedObjects instead, this way you will be properly supporting undo/redo
onyx harness
But it really depends on what you are trying to do
SerializedObjects might be overkill for many tasks
lone quarry
I'm just trying to save ScriptableObjects nothing else
onyx harness
Well it should be fine then
lone quarry
ok thanks! 😄
distant atlas
they way I see it, they're just trying to encourage people to use SerilaizedObject when editing, since that automatically handles recording to undo history for you
regal jasper
exactly, because by using EditorUtility.SetDirty (without doing others additional steps) will cause every action to be destructive
visual stag
The only time I would use SetDirty is if it's an asset that I don't want to record undos for
which is the circumstance they talk about using it for I think
brittle cosmos
So I've got an array of objects, each with a bool selected property.
eg.
I want only one to be selected at a time.
onyx harness
And what object are you working on?
brittle cosmos
If I just set SerializedProperty.boolValue in OnInspectorGUI will that mess with the undo/redo?
I've got serializedObject.Update(); at the start of OnInspectorGUI, and serializedObject.ApplyModifiedProperties(); but to be honest don't really know what exactly those do. Will they handle all that?
It's just an array of Serializable objects
My own custom classes
onyx harness
Have you tried? 🤔
Update() will look at the target and update its data to match.
Apply() will set the modifications to target
brittle cosmos
I will try, I was just wondering how undo/redo is handled
onyx harness
Oh you can try on simple case and see the result
No need to implement hardcore stuff
And I might even say, never do that
brittle cosmos
Actually, how would I do this - is there some way when using EditorGUI.PropertyField to tell if that property has been changed by the user?
brittle cosmos
Thanks, that's it
brittle cosmos
Ok so another problem I'm running into:
It seems like editors are created new every time you select the object
Which is unexpected, but fine I guess
Problem is it seem like there are two instances
onyx harness
Oh you don't imagine how works the Editor under the hood XD
brittle cosmos
The screen shot above is me selecting it three times
waxen sandal
They can't really keep the editor cached for the life time of the application
onyx harness
Is it an issue?
waxen sandal
So it's better to be consistent and recreate it
brittle cosmos
It is an issue. I'm still busy with the thing I was trying to do above, keeping only one item selected at a time.
waxen sandal
This is why you have serialization
brittle cosmos
So I thought I could store a reference to the currently selected item in editor class, then unselect when a new one is selected. Problem is it seems like there are two editors running, and so only one is updated
I can understand recreating it every time, but having two running at the same time is a problem.
Is that expected, a bug, or just something I'm doing wrong?
sterile spire
what usually works for me is setting everything that must be remember as static, initializing it OnEnable, and erasing it (if necessary) OnDissable... and I put everything that must be persistent between sessions as serialized information on the editor's target's script
brittle cosmos
aah, smart.
sterile spire
you can also make every method static, and pass the target as a parameter... so you can have some kind of reusability, coz as far as I know, you can't have two editor scripts running at the same time DX
onyx harness
@sterile spire @brittle cosmos Unfortunately, this is wrong.
You can have multiple same Editors running in the Inspector.
If you have 3 Colliders on a GameObject, you will end up with 3 Editors.
sterile spire
just tested it... and that's true O_O
but the scripts must be on the same game object... is there a way to activate the editors of the children? or... of another game object, at the same time?
onyx harness
Nope
The Inspector has a ActiveEditorTracker that create and manage Editors internally
It stays in the scope of the selection.
brittle cosmos
a static field solves my problem though. I'm not really sure what else to do because there are two editor instances running for a single component.
onyx harness
How do you know that?
How do you list them?
Because, you need to know, whenever you select a GameObject, 1 + N Editors are created.
1 for the GameObject, then N for the Components
That's maybe why you see 2 new Editors
In order to help you, I need to know the target of your listed Editors
To ensure your debugs are not misguiding you.
brittle cosmos
So in the screenshot I posted above. I'm logging the instance id on enable. I only have one component, but get six OnEnable selecting it three times.
onyx harness
Oh, you log it in OnEnable.
It means they all come from your custom Editor
And what happens in OnDisable?
Can you unlog? So you just keep a list of what is living
brittle cosmos
That's selecting the gameobject with my component once, then deselecting it.
brittle cosmos
hmm, still don't understand why there are two though.
onyx harness
If you don't mind, send me your stuff, I will check, otherwise, move on, I'm sure you have better things to focus on
cloud wedge
is there a way to use AssetDatabase to get all assets in a directory or all assets in a directory of a certain type?

you can have a path to a directory
that function name could mean, "give me all the assets in this directory," but it can't be used that way

Hello ! I'm working on UIElements and I try to set ObjectField.objectType from UXML. It's working right now, but I have to specify Namespace + Class + Assembly to make it work with Type.GetType()

Is there a way to get rid of the Assembly part, like checking in every assemblies?

If performance/time is not an issue for you:

for (int i = 0; i < assemblies.Length; i++)

{
if (types[j].FullName == fullName)
return types[j];

visual stag
I think I misunderstood the question, assuming you were talking about a UXML thing
onyx harness
(Funny enough, a dude on unitydev Slack asked the exact same thing yesterday, I just copy pasted)
visual stag
Why would you want to do it this way instead?
onyx harness
@visual stag I noticed that X)
calm thistle
The reason is I'd like to get editor windows from uxml+uss only
visual stag
ah, so it is a UXML thing? It's just weird because in c# land we have easier access to the type
Why wouldn't you just do typeof(VisualTreeAsset)? I feel I'm missing something
maybe that was an example or something...
calm thistle
It is, but the question is about Reflection (getting a fully qualified type name form text)
I have the type from a string in UXML so I must convert it.
visual stag
Depending on your needs there is also
Unsupported.GetTypeFromFullName```
But I suppose that's harder to debug if things don't work out, and is Editor-only. But it's good to know aboutHaha never noticed this one, shit (Good catch)
calm thistle
Editor-only is ok 😃 Thank you !
cloud wedge

hi, i have an little issue when i try to import a sprite from path
GameObject.Find("Slot" + z).gameObject.transform.GetChild(0).GetComponent<Image>().sprite = Resources.Load<Sprite>(Application.dataPath + "/Icons/Axe_01.png");
when i do that, my sprite is white
but the path is correct
and when i do
Debug.Log(Resources.Load<Sprite>(Application.dataPath + "/Icons/Axe_01.png").name);
the debugger say :
he don't see the sprite
but the path is correct
can you help me please ?
onyx harness
@rich gate The sprite is white because it is null (not found).
Confirm that the asset is setup as a Sprite in the Inspector.
rich gate
i have find another way
and that work
but
the sprite have mip map
and he is blurring
how can i disable the mip map in the sprite generation ?
onyx harness
@rich gate Use the other constructor to disable the mip map
rich gate
?
onyx harness
You see, you should follow my advice above X)
Gimme a sec
WWW().texture won't allow you to create the texture the way you want
You need to do it the proper way.
By properly setuping the asset in the editor
rich gate
i wish load dynamicaly the assets
only when needed
because the game will take the item ID, and get the icon path on a SQL
rich gate
the sprite isn't on the ressource folder
because i don't want to load at the game starting
onyx harness
If you want me to help you, you need to at least try what I am asking...
onyx harness
Yep
Put that in a Texture2D variable just a line above
Don't set the sprite yet
If it is not null. Your asset is a valid Texture2D.
Then it means, you just need to correctly set it to Sprite in the inspector
Like this
rich gate
for Ressource.load, the asset need to be in Ressources folder
but i can't put in, he appear just one time, and after a restard, he dessapear
i'm not stupid...
i have already try the Ressources.load
onyx harness
Well for your information
rich gate
and Ressources are loaded at the game starting
onyx harness
Resources.Load() loads from any Resources folder
rich gate
i don't want that
onyx harness
Your asset is in Assets/Icons/
It can't be found by Resources
Hum..
You just wrote that above
If you know that, why is your asset still in Assets/Icons?
rich gate
i have make a Ressources folder before
onyx harness
and it was not working?
rich gate
and i have Debug.Log the lenght of the Ressources
onyx harness
You must have done something wrong.
onyx harness
How do you get the "length"?
rich gate
idk
onyx harness
Because Unity editor does not load effectively all the assets at start
If you click on them, Unity will load them and will "know" them. (Therefore appearing in the result of FindObjects())
rich gate
but another question
that work perfectly like that
but that add MipMap to the icon
how can i disable the mip map ?
hoary surge
import settings didn't work?
rich gate
import settigns don't load at start ?
hoary surge
import settings should be constant as far as I know
onyx harness
WWW is loading from a distant path.
It is not reading any import, since it is raw data.
hoary surge
public Texture2D(int width, int height, TextureFormat textureFormat = TextureFormat.RGBA32, bool mipChain = true, bool linear = false);
mipchain = false
also it's possible to convert texture2d to sprite
I've done it but I'd need to dig up the code.
onyx harness
He did that already
hoary surge
ahh
onyx harness
But since its texture is not properly set, he sees blur stuff

I was wrestling with a BSP/DFS/BFS implementation in C# and the lack of pointers make me sad
onyx harness
DFS BFS?
hoary surge
Honestly twas a interview question I choked on 😛
got home and had to sort it out
mainly because it was annoying
onyx harness
How good are they as lookup algorithm?
rich gate
hoary surge
DFS complexity is O(V+E) and Breadth first is O(|V|+|E|)
hoary surge
DFS and BFS are the 2 most standard tree algos that I know they vary on implementation though
hence why C# doesn't have a tree or graph structure
It's been like 20 years since I had to worry about trees, dfs or bfs though heh
rich gate
RGBA32 is the better format ?
hoary surge
It's larger
onyx harness
@rich gate this is what I told you about look out the other constructor XD
hoary surge
"Better" is up to the artist to decide along with the system requirements
well not that the artist dictates system requirements, but... that the system requirrements dictate what's possible
onyx harness
@rich gate also, I hope you don't plan on making it work on a build, because this code won't work outside the editor
rich gate
DXT5 is not lighter ?
onyx harness
It is.
onyx harness
But you need to fill its prerequisites
hoary surge
in theory but all compression algos have things they can't compress all that well
or a point at which things look like poo on a poo cracker
That looks like in game GUI you are making not designer stuff
and for that editor only is going to back fire on you

You are expecting an instance of a Type and you would like to wrap it around an enum? 🤔
What is the idea behind?

there is a World singleton

they don't really have to exist past initialization

How to properly delete .cs file? If i delte from vstudio it works fine, but if i delete from Unity it goes apesh*t and then vstudio starts throwing error "cannot add project to solution becuase project Game alrady exist"
and as soon as i launch unity editor with the file deleted it ruins the solution
so it throws error
sage summit
usually deleting in Unity should work as VS automatically should reload the project.
you could try deleting the .sln and .csproj files, as those will be regenerated new in unity
urban monolith
figured unity just ruins .sln by adding same project like 8-10 times for no reason so i just copied .sln from backup and that did the trick

hey there, I made a quality setting level per platform we want to target for my game, and I created a quality setting preset file to save them. I would like to apply this preset just before building the game, so during runtime I can select the level depending on the platform. I've seen that you can use ApplyTo with a preset object, but it take an object in parameter. Where can I find the QualitySettings object? thanks!
I've found this: https://docs.unity3d.com/ScriptReference/Presets.Preset.SetAsDefault.html will check if it works.
Presets of type 'UnityEngine.QualitySettings' can't be set as default.
rip me
warm jacinth
I came to a workaround, loading the qualitysettings asset by code, and applying the preset on it
SerializedObject qualitySettings = new SerializedObject(AssetDatabase.LoadAllAssetsAtPath(qualitySettingsAssetPath)[0]);
qualityPreset.ApplyTo(qualitySettings.targetObject);
qualitySettings.ApplyModifiedProperties();```

Hello everyone, is there any way to make a script automatically include other scripts whenever I add it to a GameObject? So for example, if I have scripts A, B and C, I want to drag A to the GameObject I want and by adding it scripts B and C are also added.
onyx harness
@gray portal [RequireComponent]
gray portal
That easy, huh? Thanks! Follow-up questions:
- Can these scripts be added minimized? (In the above example, only B and C would be minimized)
- Can I control, through either inspector checkboxes or buttons, each script's state? E.G. by ticking a checkbox, I would disable B and vice versa.
Sorry if these are obvious, googling didn't show up anything.
onyx harness
- Not really, for that there is no easy solution, you need to dive into the Inspector & Editor code.
- Yes technically you can.
You have the message OnValidate() that helps you receive an event when the Inspector is modifying a Component.
https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnValidate.html

Hi guys, do you know if there's any way to make a .unitypackage via script?
I.e. to automate the steps of Export package and then selecting a bunch of files manually?
It looks doable taking into account that unitypackage is basically tar.zip with assets+meta and path
But wanted to make sure there's not a solution already done

doh, perfect, thanks!

I'm into EditorScripting lately. Since we're working on 2D games with frame by frame animations managing sprites/animations was a pain in our last project.
Learning => making a AnimationClipCreator. Still rough around the edges, needs further adjustment, but I'm pleased with the results so far 😃

how do i tell if an object is a folder?
or an asset is a folder
nevermind, got it, AssetDatabase.IsValidFolder(string path);

@whole steppe just ask the actual question
zealous ice
We'd much rather have you ask "How do you add two ints in C#?" than "Can someone help me?"
For this dropdown? I would go with simple vertical layout group
Then you can populate it with dropdown labels or resource labels
I don't think there is a built-in feature for that
visual stag
But, this is #↕️┃editor-extensions , a channel about extending the Editor. #📲┃ui-ux is for runtime UI - so I'd take the question there
zealous ice
Good idea, I missed it's existence

@zealous ice Thanks for suggesting the vertical layout group. Ill research this and how to use it .

How to i make a popup dialog when i launch the editor but JUST when the editor is launched ?
I tried this:
[InitializeOnLoad]
public class Welcome : EditorWindow
{
static Welcome()
{
Init();
}
[MenuItem("Example/ShowPopup Example")]
static void Init()
{
Welcome window = ScriptableObject.CreateInstance<Welcome>();
window.position = new Rect(Screen.width / 2, Screen.height / 2, 250, 150);
window.ShowPopup();
}
void OnGUI()
{
EditorGUILayout.LabelField("This is an example of EditorWindow.ShowPopup", EditorStyles.wordWrappedLabel);
GUILayout.Space(70);
if (GUILayout.Button("Agree!")) this.Close();
}
}```
The documentation claims that the [InitializeOnLoad] attribute works when the editor launches but
1- it also fire anytime the editor compile scripts
2- when it fires on launch the dialog box fires before the editor so it sticks it self in the upped corner and dies when the editor comes after@@heavy tiger Use time properties to define if you are on the very first frame.
So you are saying it instantly dies?
heavy tiger
well i dont know if it dies it just get covered by the editor but its not the problem, the problem is that i just want a popup window to apear when you launch the editor but the only thing i found to trigger the creation of this popup is [InitializeOnLoad] but it initialize every time something changes in the editor not just when it launch
i compile code, it fire the the initialize
i play the game it fires the initialize
visual stag
Mikilo suggested a solution to that
heavy tiger
i dont understand a time property ?
isn't there a event "editorLoaded" or a OnStart() for the editor ?
visual stag
No
heavy tiger
ok
visual stag
Give EditorApplication.timeSinceStartup a go
heavy tiger
ok i'll see
midnight hollow
Alrighty then. Finished my little AnimationClipCreator! :)
Since our workflow is based around frame by frame animations with packed Sprites (using TexturePacker!) this tool will come in handy for our next project(s)
What we can do:
- drag either the packed PNG or the TexturePacker-File itself into the list
- or select single sprites
The Creator loads each single Sprite-Assets which is packed, puts it into a list and sorts it by name. It#s important that the naming works, so each Sprite is put in the correct AnimationList, and by naming I mean the actual name and the indexnumber at the end.
Then the actual clips are created using the sorted animationlists and the settings (eather single or global), works pretty well now 😄

@heavy tiger Oh sorry, it is the values in the static class Time & EditorApplication.
Copy them in any text file and alt-tab them.
You will see what comes out
coarse hull
for a text area in a unityeditor window, how would I loop through the text and color specific parts specific colors in the text area?
visual stag
Not sure exactly, but the things to look up are Rich Text https://docs.unity3d.com/Manual/StyledText.html, perhaps you could copy the TextArea GUIStyle and set https://docs.unity3d.com/ScriptReference/GUIStyle-richText.html, but I'm really not sure if that'd make it work
coarse hull
I've been searching for a while, can't find anything that makes any sense at all
because unity has 5 different ways to do the same thing via code that are in different namespaces, when talking about unity editor ui
onyx harness
@coarse hull Can you be more explicit? O_o
coarse hull
in what way?
onyx harness
"loop through the text and color specific parts specific colors"
coarse hull
"EditorGUILayout.TextArea"
how would I color different text in it different colors
example: looking for letter a, recolor to blue
rest is green
coarse hull
how do you use that in a text area?
onyx harness
The text you provide to TextArea(). It must be like this:
TextArea("<color=green>We <color=blue>a</color>re green</color>")
coarse hull
you can do that?!
onyx harness
I understand it is in the Unity UI doc, that's why you were disturbed
@coarse hull Make sure the style used by TextArea() has Rich Text enabled.
coarse hull
how do you do that?
onyx harness
As a last argument, you can provide a specific style to TextArea (or more generally, to any GUI methods)
coarse hull
oh that's what that means
onyx harness
If you provide none, the default GUIStyle for this GUI will be used
The one used by the editor is EditorStyles.textArea
And I just checked, and it is set to false by default
You need to create a copy of textArea
By doing :
GUIStyle style = new GUIStyle(EditorStyles.textArea);
style.richText = true;
Remember to always create a copy of a style, and never modify built-ins!
coarse hull
see this is why I am so confused
docs use this text = EditorGUILayout.TextArea(text, GUILayout.Height(position.height - 30));
then there are like 30 different ones
onyx harness
GUILayoutOption are different
It is just a convenient way to override UX details
GUIStyle gives the global rendering, and the options override some stuff
coarse hull
how do I put text into this? GUIStyle style = new GUIStyle(EditorStyles.textArea);
visual stag
You don't
onyx harness
You.. dont?
visual stag
you pass style to the TextArea function
onyx harness
GUIStyle style = new GUIStyle(EditorStyles.textArea);
style.richText = true;
EditorGUILayout.TextArea("<color=green>We <color=blue>a</color>re green</color>", style);
wait but I need a text area where I can put text into that is colored
ohhhhhh
🤦 🤦 🤦 🤦 🤦 🤦 🤦 🤦
thanks again xd
onyx harness
You need to lookup method overloads
coarse hull
I really do
onyx harness
@coarse hull Also, cache the style, don't create a new one every single frame
coarse hull
got it
coarse hull
@onyx harness for every OnGUI I have to loop through everything, remove all html stuff, then add new html back. Is there a simpler way to do color that isn't html? If there is html then I can't use html in what I am doing
onyx harness
I know no other technique to color text.
coarse hull
darn
visual stag
it's not html for a start, but just store the string and use a ChangeCheckScope to see if the string changes and alter it there
onyx harness
I would probably cache your colored text.
coarse hull
@visual stag but I just checked, CCS doesn't give a specific scope
visual stag
uhwhat
visual stag
Are you changing your string elsewhere?
coarse hull
I am making a colored script editor in unity
so if they modify stuff I need to remove and readd color anyways
visual stag
Is the only place your string changes in the TextArea?
visual stag
using (var cCS = new EditorGUI.ChangeCheckScope())
{
//text area here
if (cCS.changed)
{
//colour and cache your text here
}
}```and also colour and cache your text when you load the file
coarse hull
but the issue is if they change text in a spot let's say (<c> means color):
<c>static</c>
they do this
<c>staatic</c>
that means it only modified in the middle, not allowing me to modify the color according (or remove it)
they can't see or modify html
visual stag
I really don't know what you mean
coarse hull
oh you are saying cache it for the next frame
@visual stag how would I handle using html?
visual stag
crying
coarse hull
like if I have html in the file, how do I make it ignore the richtext
while my color additions still working
visual stag
there is a way to generate strings that get ignored by the rich text parser, I'll see if i can find it
but it's a bit of a pain to be honest
coarse hull
if you could find it that would be great!
visual stag
I can't find the resources. But I think you can either replace the angle brackets with U+3008 and U+3009, or I think you can put another tag immediately after the opening bracket. Like this word is <<b></b>color=red>red<<b></b>/color>. I think I've done the latter one before, but I can't say if it scales or the pain points. That's why I mentioned crying 😛
onyx harness
Use this trick /⧸ XD
The second 'slash' is hidden, but will disable rich text
@coarse hull Oh crap, I think misunderstood what you were looking for...
TextArea is for editing text, not displaying it
-_-
visual stag
Yeah, I'm really not sure how it all works out
coarse hull
I am trying to display and edit
both xd
vertx I already found both sites that said those two things, neither would work
visual stag
If the text area is really wigging out during editing you could use a textArea when the user is editing, and then use something with that style when you're not. Whatever you end up doing it doesn't sound very friendly 😛
coarse hull
-_-
visual stag
lol that longer face got bot'd?
onyx harness
I just tried TextArea with rich text, it works, but it is obviously not convenient at all to use
onyx harness
But clearly
Your way of doing it is wrong
You can't display '<tag></tag>' and apply itself to itself
By design, your idea is wrong
coarse hull
?
what do you mean?
How do you edit a text area from code while the user is editing it?
mystic swift
How can I propagate an RGB value to sprites, and then have each sprite modify it according to its own desires for Saturation, Brightness and Opacity? In editor, so that this can be done dynamically, like a sprite theming mechanism.
deft sundial
how do i use this parameter
onyx harness
@mystic swift get the texture, GetColors() from the texture, replace the colors you want, SetColors(), Apply.
@smoky radish you did it! 😇
mystic swift
@onyx harness Sorry. I have no idea what texture you're talking about.
onyx harness
@mystic swift Texture is the base of a Sprite
Sprite comes from a Texture
@deft sundial i've never seen a question that is so clueless
mystic swift
@onyx harness I don't think that has anything to do with what I'm asking about. Imagine a colour component script attached to a master object. Changing its value changes the sprite renderer colour of a dozen or so "children", each of whom sets their own opacity, saturation and brightness upon this base RGB value they've "taken" from the master.
Because RGB is the language of Unity, yet I'm wanting to use that only as a Hue, and then act within each "child" sprite based on that Hue, and change to various levels of saturation, brightness and opacity from that Hue, there needs be some.... here's where I'm confused.
onyx harness
@mystic swift lol, that is lightyears from what I understood X)
Look for OnValidate()
mystic swift
@onyx harness Cheers!
smoky radish
@onyx harness Yup 😄 That was some weeks which I wanted to publish it on github. Thanks for your help. I appreciate. What is your github id ?
onyx harness
@smoky radish Github id? I almost never use GitHub but here is mine: Mikilo

Hello,
I have a question about linked objects with other objects. The point is that I have a door that has a controller with a button to open it and the button is still linked to another object that the button allows / disables and I need something that would somehow make the line of connected objects visible. Is this possible? It occurred to me to do it through EditorWindow and in that somehow write down the objects, it would probably be, but rather if something does not exist on this one.

@burnt tulip just ask, if anyone will be able to help, they will answer

I just started using Unity 2019.2.0b5 version. I got this problem when i create a script in unity and try to open it with VS17, the page is blank. The older versions of unity works just fine with VS. I cant seem to find a fix for this problem. If someone knows the problem plz help 😃
vestal perch
u use double click in unity or even opening manually from file folder shows blank file too?
burnt tulip
if i open the file outside of unity it shows the code 😃
vestal perch
did you switch your default code editor in unity settings to new VS?
burnt tulip
yes i did check that VS17 or 19 was used in the settings.
i just find it frustrating if i use unity 2018 it works with no problem, but in 2019 version it cant seem to open any script in a meaningful way 😛
stark geyser
Yep, .2 and .3 uses new plugin which is not 100% yet
burnt tulip
i will give it a try with 2019.1.7f1 version
yes it worked with this one. I can't believe i just spent my day trying to fix this 😄
thanks for the help guys 😉
sterile spire
hi! is there any way to draw an image on scene gui from an editor script? something like Handles.DrawSolidDisc but... instead of drawing a disc, it draws a sprite
(i mean... without instantiating a gameobject with a sprite xD just an image drawn into the scene when the object is selected)
sterile spire
thanks for the links! but I was thinking in something that let me draw a .png image into the scene... I've read the documentation of EditorGUILayout, but couldn't find any method to draw .png images in the scene :C
sterile spire
@nimble stag do you have an editor script?
sterile spire
@onyx harness seems like i am going to have to learn to use the rect ;n;... I has been running away from that since I started to learn editor scripting hahaha.... thanks for the help!
onyx harness
The Rect is just a position relative to the top-left corner of the window
Make some tests, it's nothing fancy
sterile spire
when you say it that way, it really doesn't sounds fancy xD... ok! will give it a try
nimble stag
@onyx harness Technically? What I Need is after button find all gameobject what I want and put in editorwindow
onyx harness
For that I guess you have an array of GameObject
When you press the button, you create a GameObject, add it to the array
In your Editor, loop over the array with your stuff
nimble stag
Yeah that is make sense... But What I make this array? I today find this cool stuff (editorwindow) ...
onyx harness
It is cool indeed 😄
nimble stag
Complete dynamically editor probably not works, right? ... If I make a dynamically fields after select gameobejct and press button -> show linked gameobject via scripts ...
Is it possible to do this?
onyx harness
If I understand you, yes.
nimble stag
What I this do? I dont understand why not put in editor dynamicaly fields after press button ... Then it comes to me that I can't do what I want to do
{
for (int i = 0; i < m_WallTorchs.Length; i++)
EditorGUILayout.ObjectField(m_WallTorchs[i].gameObject, typeof(GameObject), true);
}
else
GUILayout.Label("Neni Torch");```This works similarly what I want 😃
onyx harness
That's a good start!
nimble stag
Thanks 😃
nimble stag
@onyx harness Thanks for a little help 😃 That is amazing! Finally, I don't have to click through it and look for linked object via scripts! https://ctrlv.tv/B9tU

@wild star i don't know if you can detect a clic in any handle... but you can add a button https://docs.unity3d.com/ScriptReference/Handles.Button.html (I hope the answer doesn't come too late)

@wild star I would say HandleUtility.s_NearestControl might be a clue.

Is there any guides/documentation for the UI Elements GraphView?
whole steppe
How would I redraw an editor based on the value of something, such as an enum? (using UIElements)
onyx harness
@whole steppe if (value) Repaint() ?
visual stag
You need to register a changed event on the control
and then call a function that clears and rebuilds
It really depends on the context
whether you're in control of the editor yourself
You can also just cache the entire hierarchy and unparent and build/reparent a different cache if it's the kind of thing that changes a lot
UIElements is good for that sort of thing
whole steppe
Yeah, i did that first part, but wdym by clear and rebuild?
visual stag
you have a function that builds your entire UI, or just the part of the UI that changes based on the enum
So just call Clear on the relevant VisualElement
and recall the function that builds the children based on the state of the enu,m
whole steppe
Ah, I see
onyx harness
Hahaha I'm so out of the game about UIElement XD
visual stag
@onyx harness it makes so much more sense having a persistent UI 😛

Thanks to both for helping, I got it now
onyx harness
Don't tell me... I don't know who got the idea of IMGUI and more over, who approved it O_o
visual stag
I love IMGUI, it's really easy 😛
it's just difficult to do complex things
complex things are easy if you have state
onyx harness
Don't get me wrong, IMGUI is supa nice for prototyping.
But I am talking about IMGUI approved for runtime 🤔
visual stag
omg I remember programming my first UI in OnGUI back in the day
such a different era
visual stag
I can't wait until it actually looks and feels like something I'd like to be using 😛
onyx harness
What is it lacking right now?
visual stag
Other than it being buggy, it just doesn't feel like it has good UX and is extremely clunky
Very early days though, so it's likely improved a ton since I checked it out a few weeks ago
onyx harness
Few weeks ago? Oh gosh...
severe python
If doing complex things is difficult, then is it really easy?
but even so, like, text alignment and imgui, aligning buttons? How about aligning custom popups?
shakes his head, no
never, again
takes IMGUI out back and executes it with extreme prejudice
surreal quest
Anyone know (specifically for property drawers if it matters) if theres a way to show something generically? Like if I have a value, and I don't know what it will be, is there a way to just display it as it would defaultly be displayed? Whether its a int, a string, or some custom serializable struct?
regal jasper
EditorGUI.PropertyField does exactly that (or EditorGUILayout.PropertyField if on a CustomEditor)
surreal quest
Right, but I need a serializedproperty for that right? What if I have a literal like, int? Like
int bob = 5;
on a propertydrawer you already have access to the serializerproperty
surreal quest
Okay, but I'm trying to get a specific value. Like in the case of a dictionary. If I have a Dictionary<int, string> or something, and I'm trying to get each key and draw each key to the editor, but I dont know if its gonna be an int, or if itll be a double, or whatever - even a custom struct, and I need to get each value to draw each one, and i just have the value?
regal jasper
Dictionary is not serializable, if you are serialiazing it with a ISerializatioCallbackReceiver using Lists, then you can access the list property through FindPropertyRelative and so its individual values
surreal quest
I realize a dictionary is not seralizable, I realize alternative options, and that did not answer my question.
regal jasper
You can create a SerializedProperty from anything that is seriablizable by Unity, then you can use a PropertyField to draw it as it originally is
EditorGUI/EditorGUILayout.PropertyField is the answer for your question
whole steppe
I'm trying to use UXML and I have an enum field, but I'm not sure if I am passing in the type correctly.
<editor:EnumField type="MyEnum"></editor:EnumField>
In the inspector, the enum dropdown is empty.
In order to set the right enum, I have to do it in my editor code, which works
But I feel like I shouldn't have to be doing that

Is it fair to say Github for Unity is terrible? I'm at my wits end getting it to work properly enough to allow me to push anything beyond the freaking .gitignore and .gitattributes files.
It won't even allow me to commit anything. 😦
I've removed the extension and whatever else github leaves behind and tried it a second time following the instructions on the github for unity site... Same result.
Even more fun, the command line stays frozen when I try to open it from the extension.
Never mind. I figured it out. The command line thing is still screwed up. But it was something I left out when attempting to commit. Sigh.

Guys, i got these errors when i try to use Test runner. Do you know solution?

Copying assembly from Temp to Library issues of course. I've had these before, not positive how I got rid of them. Been forums searching for about an hour.
Anti-Virus has an exception for the project folder.
Tried unchecking the 'Read-Only' windows explorer option however it gets stuck and doesn't find some of my asset files.
Seems to be a fairly common issue. Tried recompiling scripts however my Unity just doesn't want to do that.

How do I get a property of a property that is a class?
Example. I have this serializedObject.FindProperty("_myClass"), where _myClass is a class that contains another field that is something like private float _myFloat;. How do I get _myFloat from serializedObject?
slate pecan
var prop = serializedObject.FindProperty("_myClass");
var myFloatProp = prop.serializedObject.FindProperty("_myFloat");
var myFloatValue = myFloatProp.floatValue;
@gloomy chasm
regal jasper
It is wrong, instead of prop.serializedObject.FindProperty("_myFloat"); you should do prop.FindPropertyRelative("_myFloat");
gloomy chasm
Ah thank you both! I was close.
wanton girder
Getting the same problem as before. Copying Assembly from Temp to Library failed.
I've restarted Unity many times, Restarted my PC.
I've excluded it from my Anti-Virus.
And tried unchecking the 'Read Only' box in properties of windows explorer however it's failing to do so for some of my assets.
Been forums searching and no solutions.
My only other option right now is to 'Reimport All' I guess?

I had a weird permissions issue with folders on my machine once. The solution was to duplicate the whole folder and delete the original. That got me my write permissions back and problems went away. I think the problems started when I rsynced the folder from one machine to another.
wanton girder
Okay I'll try that. Thank you.
wanton girder
I think the issue is because I imported a package, the scripting runtime version changed however I'm not sure how to fix this. I've gone into my configuration settings of the player (Edit -> Project Settings -> Player -> Configuration ) and made sure everything is up to date. Seems like while changing scripting runtime, it's corrupted my assembly files. However upon deleting my library folder in an attempt to rebuild all of my assembly files I just get the same error anyways.
wanton girder
Update: Duplicating the file did not work, the file is still read only. Could this be due to a virus?
tacit jasper
im not sure if this is even relevant @wanton girder
but if you installed any of your assets using "pip" you might need to reinstall with the "-e" paramater
which IIRC makes the assets editable

Hey there, I am working on a little editor tool. Wondering if the following is possible through the editor API:
- Generate a meta file for a new asset created by
new FileStream(rather thanAssetDatabase.Create) - Create a new script component on an asset and assign its UUID (despite the script not having been compiled yet).
- Get the UUID of a component attached to a gameObject.
- Assign a component by UUID to the new uncompiled script component.
Taking a step back, the UX flow is this:
- Select an object with an
Animatorcomponent - Generate a new MonoBehaviour script
- Refresh the directory that the script was created in so that the user can see it (currently it's not appearing)
- Assign the new script to the selected object
- Assign the
Animatorcomponent on the object to the new script's serialized field
I'm certain this is possible, but ideally I wouldn't have to get down into editing the actual YAML.

Trying to display my sprite on my Editor window. How can I create the sprite field ? The same one which appears when you click on any sprite at the bottom right?
visual stag
can you screenshot which field you mean?
If you're talking about the preview window it's using EditorGUI.DrawPreviewTexture
and if you want the checker you can reflect to EditorGUI.DrawTransparencyCheckerTexture first
wheat turtle
Hey, so I am writing an editor window script, this is my code
GUI.backgroundColor = editingDir1 ? focusColorPositive : focusColorNegative;
using (new GUILayout.VerticalScope("Box"))
{
GUI.backgroundColor = defaultBackgroundColor;
MakeDirectionArrows(index, i, j);
}
so like the background only changes sometimes but my bool editingDir1 is changing everytime i use scrollwheel, i am not sure why
this is gif of the issue -> https://gyazo.com/69ee10034b58b41b98d9aebe468b03e9
i feel like that the editor is having some kind of a lag or something
like when i move the wheel real fast and for long
it does change the color after an inter
does it have to do something with the using statement?
but i do need to change it back to default before calling anything in the statement
random flume
Ah yes it was DrawPreviewTexture! @visual stag Much love man
random flume
var style = new GUIStyle(GUI.skin.label);
style.normal.textColor = Color.white
This seems to change the color of all text in the inspector too

How can I programmatically create a csharp file with a meta file in an editor script/
regal jasper
Just create a file with the extension .cs and then call AssetDatabase.Refresh()
barren moat
Cool, that's what I'm doing. 😃
I was worried that the reimport would cause a compile and kill the script
But I guess it will wait?
We'll see
I want to get the meta file before the script ends.
regal jasper
if it has compiler errors, yes, it will
regal jasper
barren moat
Cheers.
I'll play around with it.
Problem is that I want to add a generated component to an object
But I can't call AddComponent<T> when T doesn't exist in the code that's running!
regal jasper
hmm, this is will be a little tricky, but you can achieve that with AssemblyReloadEvents (it has some limitations, but you can overcome those by subscribing to EditorApplication events once the recompilation finishes
but well, hope that works for you
dire urchin
I am editing blendshapes on an asset, and setting it to dirty in an editor script, and all goes very well until I reopen the project
all changes are lost. I have been looking everywhere for how to actually save the modified asset, but I get countless suggestions to setdirty and save the project, both of which do not solve the problem in my case.
Has anyone been able to modify an fbx asset's mesh and keep the changes through a project reopen?
regal jasper
@dire urchin the FBX asset is kind of "read-only", if you want to persist the modifications you will need to create a prefab out of it first AFAIK
dire urchin
Thanks. I think I found a good solution by writing an asset postprocessor instead of an on demand editor. It does save changes so it is obviously not read only, but I guess unity does not offer that kind of access on demand?
regal jasper
oh right, forgot about the postprocessor 🤦
smoky radish
Hey guys,
I found out using Resources is not a good approach to find assets in the project. (https://docs.unity3d.com/Manual/BestPracticeUnderstandingPerformanceInUnity6.html)
Although I just use it for loading ScriptableObjects and it is better than other type of assets like material, prefab, textures and so on but it still increases size of the build (Especially if creating mobile game).
So I want to know if it is good to use AssetDatabase instead of Resources for loading ScriptableObjects which are used in editor and PropertyDrawer ?
onyx harness
@smoky radish If I had to choose between AssetDatabase and Resources. I would pick the former for "most" cases.
AssetDatabase is clear on its use, it is an editor-only API.
But it some rare cases, Resources might be the proper tool.
Especially for methods like FindObjectOfTypeAll()
(Instead of using Object.Find())
Resources implies to have the assets in a Resources folder, which is not convenient, even for editor-only assets.
smoky radish
@onyx harness So you think I should use AssetDatabase in my case ?
onyx harness
Yes
If AssetDatabase can do what Resources is providing you. Use AD
@smoky radish
smoky radish
Okay. Awesome. Thanks. It does what I want.

I'm trying to do some animator editor scripting, and i've got a reference to my state withUnityEditor.Animations.AnimatorState state = context[0].animatorObject as UnityEditor.Animations.AnimatorState;. I've got a transition with a few conditions on it pointing to the next state, but in the debugger i'm not seeing the conditions array as empty and the destinationState as null... i'm kind of at a loss here. anyone have any thoughts on why these would be empty?
visual stag
If you're trying to set something from an editor context it needs to be dirtied.
The options are:
SerializedObject/SerializedProperty
https://docs.unity3d.com/ScriptReference/SerializedObject.ApplyModifiedProperties.html
(https://docs.unity3d.com/ScriptReference/SerializedObject.ApplyModifiedPropertiesWithoutUndo.html without undo)
Undo.RecordObject
https://docs.unity3d.com/ScriptReference/Undo.RecordObject.html
(https://docs.unity3d.com/ScriptReference/PrefabUtility.RecordPrefabInstancePropertyModifications.html> also required for prefabs)
EditorUtility.SetDirty
https://docs.unity3d.com/ScriptReference/EditorUtility.SetDirty.html (most lazy)
If something is changed and not dirtied, that change is transient and will be wiped.

@visual stag You forgot developer mode
visual stag
...?
waxen sandal
I use it all the time
Using the GUIView debugger
Using internal debug mode on the inspector
visual stag
The GUIView debugger I just access via reflection, and I've only needed the internal debug mode the one time I've used it 😛
Access Developer Mode via Help/About Unity and typing internal.
This mode adds icons for window repainting, the IMGUI Debugger, extra Debug options for the Inspector, and extra settings for the Console amongst other things.
(Window/Analysis/IMGUI Debugger)
Turn it off the same way you turned it on.
If you feel like we need it 🤷

I'm using NGUI for UI, but it doesn't seem to respect the new SceneVis controls -- the colliders gizmos, etc stop being drawn, but not the actual textures of the UI. NGUI author has no idea. Anyone know if there's a piece of code I should add to prevent those elements from drawing when their SceneVis is set to hidden?
acoustic timber
Hello all, is this the correct place to ask for some help on a collision script?
barren moat
@acoustic timber probably not, colliision is not editor.
Is anyone able to help me with code generation? I'm genereting monobehaviours in the editor, and I want to attach them to an object:
AnimatorWrapper.GenerateAndRefresh(toGenerate);
for (int i = 0; i < animators.Count; i++) {
var scriptName = toGenerate[i].GeneratedScriptAsset.name;
var prevComponent = animators[i].gameObject.GetComponent(scriptName);
if (prevComponent == null) {
var scriptType = toGenerate[i].GeneratedScriptAsset.GetClass();
Debug.Log(scriptType); // NULL
animators[i].gameObject.AddComponent(scriptType);
}
}
I think the problem is that the type doesn't exist in the script because it's just been generated.
plucky inlet
@barren moat you probably should refresh the asset database after generating the type
barren moat
I do
(updated script)
public static void GenerateAndRefresh(IEnumerable<AnimatorWrapper> wrappers) {
var generated = new List<(AnimatorWrapper, string)>();
foreach (var wrapper in wrappers) {
var scriptAssetPath = wrapper.Generate();
if (scriptAssetPath != null) {
generated.Add((wrapper, scriptAssetPath));
}
}
AssetDatabase.Refresh();
foreach (var (wrapper, path) in generated) {
var type = AssetDatabase.GetMainAssetTypeAtPath(path);
var scriptAsset = (MonoScript) AssetDatabase.LoadAssetAtPath(path, typeof(MonoScript));
if (scriptAsset == null) {
Debug.LogError($"Could not find generated file {path}!");
}
if (wrapper.GeneratedScriptAsset == null) {
Debug.Log($"Created '{path}'", scriptAsset);
} else {
Debug.Log($"Regenerated '{path}'", scriptAsset);
}
wrapper.GeneratedScriptAsset = scriptAsset;
EditorUtility.SetDirty(wrapper);
}
}
probably wait until the refresh is done in some callback
(i don't know which one 😃
e.g. InitializeOnLoad will get you reload in the editor
barren moat
Nice.
I am a bit confused about what happens when the code is reloaded
I thought it would kill the script tbh
plucky inlet
it would - you have to continue per partes 0)
regal jasper
@barren moat I think that your issue is being with persisting the data so that you know which script to add after, right? If that's the case, you can create a temporary json file in some place to save that info and then later delete it
barren moat
@regal jasper presumably yes that's the problem.
Types don't just appear in the code after importing the script, right?
It's kind of annoying because I'd like to basically do what I see when a script is missing in unity
Ideally I could just put an invalid component on the object and then assign the MonoScript by its GUID.
I think I will put a hidden GO in the scene and assign references to it
in serialized field
Then when the compiler calls back I'll flush the changes out
plucky inlet
i don't understand this: "Types don't just appear in the code after importing the script, right?" why wouldn't they ?
barren moat
I don't know, I don't understand C# enough
plucky inlet
are you making animation wrapper btw ?
barren moat
Yes
plucky inlet
types do appear in the assembly once it's compiled (reloaded)
plucky inlet
no, you have to reload - which unity does for you when asset is changed
barren moat
Right, well I can call AssetDatabase.Refresh() and continue
So it doesn't kill the script immediately
plucky inlet
it's not that dynamic - far from any live code
barren moat
Yeah, I didn't expect it to continue at all
plucky inlet
yea I'm not sure about all intricacies of AssetDatabase.Refresh tbh
barren moat
Fair enough.
So while I've got you
This is my currrent plan
This whole thing runs after you click a menu option, and is operating on Selection.gameObjects
- generate scripts for each component
- reload to create meta files
- fetch the GUID of each created script
- create a temp GameObject in the scnee
- put script GUID and target object in serialized list on object
- on compiler callback attach all those scripts ot their associated objects
- destroy temp GameObject
Sound like it might work?
plucky inlet
what's the end goal ? -- attach generated component on the objects selection right ?
barren moat
Yep.
The part that (attetmpts) to do this is what I pasted here https://discordapp.com/channels/489222168727519232/533353544846147585/593221451553832990
plucky inlet
well you should have the generated type/s after reload available as normal .net type so there should be need to manipulate GUIDs directly - that
would be the ideal case
barren moat
Except I need to hold on to the animator references
They're in the scene
I can't assume that the selection didn't change during reload
And I need to hold on to the assets that were generated too
plucky inlet
I'd probably try that direction first - basically your goal should be to get updated domain with new types
yep the selection will change - prob. worth to focus bookkeeping on that instead
plucky inlet
oh yea that one
plucky inlet
I don't want to mislead you entirely 😃 - there are couple of hidden assumption which need testing
barren moat
Something that can persist past the code reload
plucky inlet
yes
barren moat
(it's okay, it's been hidden assumptions all the way)
It's taken so much code to get it this far
lol
I've got asset change modifier to regenerate the scripts when the controller changes
And of course the code that actually generates the scritps 😒
I really thought I'd just bang it out haha, but it seems unity isn't exactly streamlined for this
Anyway, fun project. I'll try to do that last bit soon
plucky inlet
yea modifying code on the fly is not very straightforward -
barren moat
Then I'm going to try to make a package manager compatible repo
plucky inlet
the project looks useful if it will work seamlessly :]
plucky inlet
esp. since the whole animator setup is not very user friendly
plucky inlet
it looks like a great visual tool for e.g. state machines, but the manual setup is always a pain
barren moat
Gonna do shaders next
Material wrapper
I'll open source it, but for now it's just in a branch of our game
plucky inlet
bringing all the strings into types right - seems like a noble quest ;0)
post a link occasionally - i'll check out the animator thing it should be useful
barren moat
I can share the source now, the only thing that doesn't work is attaching the scripts
If you want to give it a try
But all the file watching and generation etc works like charm
You just need to drag them on after creation
No biggy, just a bit of a nicer experience
plucky inlet
I'm not sure if there isn't some non public API for this tbh - maybe worth to take look somewhere in editor c# reference - i'm not that of a digger myself tbh )
barren moat
I asked a unity employee and he said he would ask around
And then told me that it would be difficult
plucky inlet
hah
barren moat
oh man, I didn't even think about this
plucky inlet
btw on a general note: storing things in a hidden GO in the scene is not very user friendly - although fully possible and probably workable
but you can use ScriptableObject for storing any data - you'll get serialization in play mode for free - would need to handle lifecycle events properly though
visual stag
When Unity creates a script it just uses File.WriteAllText and then AssetDatabase.ImportAsset, which can then be immediately AssetDatabase.LoadAssetAtPath'd and returned
plucky inlet
@visual stag will that work with a new type ?
visual stag
Of course, that's what happens when you create a new script, no?
plucky inlet
new type causes reload - hence the callbacks discussion above
visual stag
Ah, alright, I've not been following along 😛
plucky inlet
you could probably LoadAssetAtPath for a new script but I have no idea what that gives you since the type might or might not be in currently loaded domain
