i wonder if i could have it embed youtube videos into help entries (optionally)
that might be kinda cool
i've seriously considered adding comment threads to them but that just seems like... too much
if anyone has any other feature suggestions let me know please
i think this is going to be the one... the first asset I actually release publicly
might try to sell it on the asset store, might release it freely, still considering my options on that
hey one of yall might know... is there a way for me to add my icon next to the standard blue help book on top edge of inspector window?
i mean i can draw it there, did that, but the foldout hotspot eats the mouse events there so the button doesn't fire, also it hides/shows when foldout is up/down which is weird, so if i put it there i think i'd need to find a less hacky way to do it
visual stag
I have attempted to replace the book's functionality (not possible) and during that time I may have attempted to inject my own in there. I have strong memories of everything being impossible
proud yarrow
yes, i tried setting GUI.depth to int.MinValue too, no joy
i could have swore i saw some custom component stick something up in there once but i don't remember for sure now
wispy delta
What's the best way to resize these icons to fit with the 'A' and 'N' buttons to their left? Right know the texture is a part of the GUIContent used by the button in the horizontal layout. Is there a better way to show an texture instead of text on a button?
I tried giving the textures read/write permission, but even with that it wouldn't let me go less than 8x8 for some reason; which was still too big, and felt icky
visual stag
for a start scale the buttons to the same size
then you may have to manually add padding to the textures themselves
I think you could do it in a GUIStyle but I tend to just modify the texture for the purpose because the less styles the better imo
wispy delta
I'm not changing the button size anywhere, I guess they default style just uses the content size?
visual stag
yeah 😃
I assume if you use the toolbar for this one (seeing as the content is small) then it won't
but I could be wrong
wispy delta
Yea, there's a fixedWidth and fixedHeight in a style, if it's 0 it'll scale to content size. The icons are gross, but it works 👍
visual stag
I almost always have to create a specialised scaled icon
it's one of the most difficult things and I get pretty proud when I create an icon that scales well
or has good scaled variations
wispy delta
Yea, I think I'm gonna have to hire someone to make the icons. While I'm not the worst artist/designer, I've put all my character points into programming
zealous ember
Hi guys, looking to display a scene into a custom windows, wondering if anybody can point me in the right direction. thanks
visual stag
wait, a scene view window? Or an object preview?
zealous ember
@visual stag
kind of integrate a scene viewer in to the UI. like the editor in below
visual stag
I'd probably create a preview scene https://docs.unity3d.com/ScriptReference/SceneManagement.EditorSceneManager.NewPreviewScene.html, instantiate some stuff into it (I think including a camera?) and then use a rendertexture as that camera's target texture, render the camera and draw the rendertexture into the GUI
forest vortex
that page really needs a lot more elaboration
reading it i'd never know what it was used for
visual stag
agreed
craggy sedge
You can also use PreviewRenderUtility for some of that stuff
Though I think that's more for the preview GUI
zealous ember
Thanks guys! that info point me into this.

How do I create multiple new scenes additively? I always get "Current mode does not support additive creation of new scenes."
worthy swan
how do I get the current open prefab
I see a prefabContentsRoot, is that the prefab or the actual root
nvm PrefabUtility.GetOutermostPrefabInstanceRoot() does what I need
worthy swan
actually seems like that's not working out for me
I'm trying to add the current open prefab to a list in an editorwindow
worthy swan
I guess it's not working well cause I'm trying to get the prefab variant
sonic wind
Having problems getting EditorGUILayout.Foldout working properly
Cant see a way to check when the label is clicked
gleaming zenith
I think that's by design
gleaming zenith
Just set it to true?
sonic wind
Doesn't seem to do anything
Im quite confused
I can get it to open by clicking it now but cant get it to close 😄
{
if (fold1 == false)
fold1 = true;
}```you know you have to use its return value?
item.Foldout = EditorGUILayout.Foldout(item.Foldout, new GUIContent(contentText), true);
you have to save it and reuse it in the next frame
fold1 = EditorGUILayout.Foldout(fold1, "name", true) in your case
sonic wind
Ah, that was it
sonic wind
When changing values from the custom inspector (below) it does not promt prefab changes (bold). Can i force it to check if the prefab is different?
worthy swan
is it possible to get a reference to the prefab variant opened in prefabstage?
dusky plover
@sonic wind You can use a EditorGUI.BeginChangeCheck to check if anything changed during the current drawing frame.
But the reason they don't become bold is likely because you didn't register with Undo.
You should use Undo.RecordObject on the object you want to change BEFORE changing it.
That registers it with the Undo system and causes the value to be persisted.
sonic wind
Thank you @dusky plover
Noticed something odd, After having removed the aboce part from the custom inspector the bottom part stopped prompting changes when typing the numbers. It still finds them when dragging the value up or down
Note it still says 'changed' after every number typed
{
Undo.RecordObject(Base, "Changes");
Debug.Log("Changed");
}```Just using these to set and get the values EditorGUILayout.FloatField(title, value);
waxen sandal
You're better off using propertyfield
sonic wind
Cant make any edits now but i'll check those out
worthy swan
"is it possible to get a reference to the prefab variant opened in prefabstage?" -- nvm figured it out.
AssetDatabase.LoadAssetAtPath(stage.prefabAssetPath, typeof(GameObject));
gloomy chasm
After doing AssetDatabase.AddObjectToAsset(page, pages);. Is there a way to get all the objects saved to asset? So is there a way to get page from pages?
forest vortex
you can use FindAssets to find a specific 'page' https://docs.unity3d.com/ScriptReference/AssetDatabase.FindAssets.html
or use LoadAllAssetsAtPath() to get an array of everything in 'pages' https://docs.unity3d.com/ScriptReference/AssetDatabase.LoadAllAssetsAtPath.html
but know that array will be object references, not just names.
'pages' is actually a folder in the assets folder.
and 'page' is an asset object.
gloomy chasm
Thanks @forest vortex. LoadAll does exactly what I want! 😃
visual stag
@sonic wind you have to call undo.record object before you begin to make changes to it, not after
sonic wind
@visual stag Ill try do that later today. the reference i was linked had it afterwards so thought it should be that way
visual stag
If you notice the example on the scripting API, it does the change to the object after (but still uses a change check) 👍 it also mentions it records changes after the function
sonic wind
Seems to work fine after moving things around, now just wondering if there's a way to see which elements are overwritten
waxen sandal
Did you check the links I sent you earlier?
sonic wind
No, didnt do that. Ill check them
sonic wind
How would you set a value with these? Didnt find any tutorials on the subject either
SerializedProperty serObjRes = serObj.FindProperty("maxHealth");
if (serObjRes != null)
{
Debug.Log("Found " + serObjRes.floatValue);
serObjRes.floatValue = Random.Range(1f,50f);
}```You can just cast your serObj to the type it actually is like MyBehaviour and then set the properties manually
gleaming zenith
so body is your MonoBehaviour?
gleaming zenith
I think you must use serializedObject.target or sth
sonic wind
seems to find that
If doing it that way i dont see a reason to use this over EditorGui
gleaming zenith
what is it that you're trying to accomplish?
sonic wind
Mostly to learn how to do custom inspectors and currently trying to list float array (size is determined by length of enum) in the custom inspector and allow changes from there to be applied to the prefab
gleaming zenith
by casting the target to your class you can modify it. From there you can do your own inspector and do more than the default inspector
in your case you should read the enum and do a for loop in the OnGUI based on the enum value right?
sonic wind
I got basically all that working but it was really fiddlish, then i was suggested serialized objects and trying to see what they are all about
body Base = (body)target;
and
((body)serializedObject.targetObject)
seem to do the same thing
gleaming zenith
Yeah I think they're the same thing but not sure about that
sonic wind
Somewhat confused about this description of SerializedProperty
SerializedProperty and SerializedObject are classes for editing properties on objects in a completely generic way that automatically handles undo and styling UI for Prefabs.
Cant see a way to set values via it
gleaming zenith
you can only set values on the direct object AFAIK
at least thats what I'm doing
sonic wind
Can you do the same thing as this button via script?
gleaming zenith
you need a copy of the original object for this
but AFAIK you have to implement it yourself
this is a prefab only feature AFAIK
sonic wind
var so = new SerializedObject(transforms);
// you can Shift+Right Click on property names in the Inspector to see their paths
so.FindProperty("m_LocalPosition").vector3Value = Vector3.zero;
so.ApplyModifiedProperties();```
Found this in documentationTry it
sonic wind
Looks like you can change the values like this
{
serObjRes.floatValue = Random.Range(1f, 10f);
serObj.ApplyModifiedProperties();
}```Any ideas on how to get value of the float array?
float value = soArray.GetArrayElementAtIndex(i);
SerializedProperty soArray = so.FindProperty("resistances");
Found it
Debug.Log(soArray.GetArrayElementAtIndex(0).floatValue);
waxen sandal
Yeah you're support to apply it on the serialized object
wispy delta
Looks awesome! Glad to help 👍
lucid hedge
anyone got tips when making rects responsive to the dimensions of your editor window?
because I don't think this is the way to do it
I'm basically getting the width of the window and then determining how many columns/rows there should be and then moving the rects
surreal quest
lol, it looks like you're not resetting the x
lucid hedge
yeah I'm not, I will but I'm just wondering if there is like an elegant way to do this
I might just get some paper and do this properly
lol
forest vortex
you've invented a new puzzle game
lucid hedge
:p
wispy delta
@lucid hedge maybe GUILayout.SelectionGrid
Not sure if you know this, but Screen.width/height doesn't just apply to the game. You can use it for editor windows as well. You'd probably need the width to calculate xCount
lucid hedge
Victory!
I'm gonna check out selectiongrid too ty
added a 'plus' slot instead of the bottom bar
I'm done for the night
good night ❤
wispy delta
looks awesome 👍
wispy delta
I'm continuing work on drag n drop gui and got it working for any Object. I'd like to add an option to allow/disallow assets scene objects.
Since the method works with any Object I figured I can't just use PrefabUtility.IsPartOfAnyPrefab() as that wouldn't work with textures, audio, scriptable objects etc.
The only other methods I found that seemed helpful were AssetDatabase.IsSubAsset() and AssetDatabase.IsMainAsset().
Do I need to check both methods or is there a better way to check if an Object is an asset or in the scene?
wispy delta
tldr: I'm creating a drag n drop field and want to add an option to disallow scene objects, whats the best way to check if a UnityEngine.Object is in the scene?
grim monolith
@wispy delta You can use AssetDatabase.Contains(obj) it will return true if it's on the project
wispy delta
Perfect, thanks!
grim monolith
np
lucid hedge
If I have an editor window open then close Unity, open Unity again, the editor window will be still open
what method will be called?
OnEnable?
Because I'm having an issue where my prefab list 'forgets' the prefabs in it when I close and reopen Unity
so it shows up as empty slots
so I want to 1) Remember the prefabs OR 2) clear the lists
okaaay
clearing the list in OnEnable() worked
wispy delta
Sounds like you got it to work, but if you ever need information to persist in a window it's best to store the info in a scriptable object
lucid hedge
Yeah I do use scriptable objects, but the prefab list only gets stored in the scriptable object when the user presses a save button, when he just adds prefabs but forgets to save it, it doesn't get put in a scriptable object so when closing/reopening Unity they are forgotten
probably should add like some info when they forgot to save it
or a warning or something
wispy delta
I believe there's a way to intercept when Unity quits but I am not sure
lucid hedge
Yeah I don't think I want to do this, messages that pop up when you want to close stuff are annoying imo, just gonna add an indicator icon in the UI that shows if the prefabs were saved or not
lucid hedge
nice method, ty
wispy delta
Also @lucid hedge I don't think you necessarily need to save it yourself. Just write to it and mark it as dirty. If it's dirty I'm pretty sure the new data will be saved when the project is saved. You may need to test that tho
forest vortex
it should be, yes
wispy delta
Obviously the original file still needs to be created, but once you have a reference to it you should be good to go
forest vortex
but having your tool hook that event and just save on exit would work
you don't really have to have it prompt the user
lucid hedge
hmmm I want to register a mouse click within a rect
with this
if (r.Contains(Input.mousePosition) && Input.GetMouseButton(0))
but it doesn't seem to be doing much
wispy delta
You have to use Event.current in editor stuff for input
In general Input is for runtime Event is for editor
lucid hedge
if (r.Contains(Event.current.mousePosition) && Event.current.type == EventType.MouseDown)
works
ty for the tip
wispy delta
You can do if (Event.current.button == 0) as well
well this is the full thing you need to do
var e = Event.current;
if (e.type == EventType.MouseDown && e.button == 0)
{ ... }
If you just check if the event type is mouse down. someone could middle mouse click or any other mouse button. That may be what you want, but it's good to know you need to differentiate between different mouse buttons
wispy delta
feels slow frame-rate-wise?
lucid hedge
there is like a delay
after I press
between the button press and the blue selection indicator
wispy delta
it may just be you need to call repaint
wispy delta
np. repaint set me back so many times. i could never figure out why the gui wasn't updating, but it was just that it wasnt repainting
indigo kiln
Im creating a very basic idle game, and would like a little help with the auto add function. So i need to add a number every second to a count variable. Would i use delta time to add it to there or WaitForSecond, or something else for the delay between adding it?
wispy delta
Are you doing this in the editor or at runtime?
indigo kiln
I want the timer to start when the program starts. so im pretty sure the timer is running in runtime.
wispy delta
Ok then #💻┃code-beginner would be the correct channel. This channel is for extending the editor, but no worries I can still help :)
You could use a coroutine like so:
float delay = 1f;
int count = 0;
private void Start ()
{
StartCoroutine (AddRoutine ());
}
private IEnumerator AddRoutine ()
{
while (true)
{
yield return new WaitForSeconds (delay);
count++;
}
}
Or you could keep track of time yourself like so:
float currentTime;
float delay = 1f;
int count = 0;
private void Update ()
{
currentTime += Time.deltaTime;
if (currentTime >= delay)
{
currentTime = 0f;
count++;
}
}
And the count ++ is what is getting added to the count, right?
gleaming zenith
@indigo kiln by idle game you mean, when you close the game it continues in the background?
indigo kiln
Okay, that makes sense to me. Thanks for all the help so far guys, i very much appreciate it.
@gleaming zenith i want it like that in the future, but right now im alright if it just counts when its open.
gleaming zenith
I think you can easily do that without much hasle
but you have to do it from the start on correctly
save a timestamp when starting the "game" or "profile" of the game status
and use it to calculate your current time
thats the best way you can to that
indigo kiln
really? so it would be the difference between when the game opens for the first time, and current time?
gleaming zenith
because you cannot run a coroutine or whatever when the game is closed
if you start the game the first time at 08:00 and close it at 08:30 you have 30min time
when you reenter at 10:00
you want the time to be 2:00h right?
indigo kiln
okay, well i need to start work now, so i have to go. But yeah, thats how i would want the game to work.
gleaming zenith
Save a timestamp at 08:00 and then you can always "calculate back in time"
indigo kiln
I need to start work, but if you comment stuff here, i can look through it. You dont have to comment the code, because i kinda want to figure it out, but thanks for idea.
that does make sense for me.
gleaming zenith
yeah if you have any questions or such you can dm me if you want
im going to sleep now xD
indigo kiln
thank you so much. Good night.

I instantiate a scriptable object, to use as a temp object for an editor.
However as the object is in memory unitys Garbage Collection will destroy the object at various times (e.g. going into play mode)
Is there a way to stop the GC on this object?
Writing the object to file does prevent it, but it also has other draw backs. I would rather keep it in memory
left gate
it is not static
i will try that, thank you
@gleaming zenith , no unfortunately it still gets destroyed
gleaming zenith
Maybe save it when OnDisable and load it OnEnable?
left gate
saving it to a file introduces a lot of other bugs ☹
gleaming zenith
that doesn't sound right
left gate
the bugs are with the flow of the code, and the asset managment with that new file
gleaming zenith
Maybe you code got too complex?
left gate
yup. its fine if the object could remain in memory
but writing to file, serializing fields, creating sub-assets, is just a pain
when you work from a file from disk
gleaming zenith
You should only need to save the scriptable object right?
left gate
hmm?
rather than sterilizing the fields? probably, but i wouldnt be supprised if i had to do that too
gleaming zenith
If you use a scriptable object you just have to save the object right? Every field gets automatically saved
left gate
it depends at which point i save the object
If i
save
make edits in code
those edits only exist on the SO thats in memory
gleaming zenith
you know when you make edits in your code -> your code gets recompiled and refreshed
EVERYTHING from your code gets thrown away and re-initialised
gleaming zenith
Thats not my experience
only the serialized objects get saved
but your code gets a refresh
left gate
no private varibles get saved too
you have to mark it with [system.nonserialized] for it not to persist
gleaming zenith
Then I dunno bro
left gate
☹

@lucid hedge That prefab painter is pretty cool and I think I may end up using it.

Is there any way to get a display like this? Both name and image. But more specifically the image. If I use OnPreviewGUI the object is much darker.
cinder cloak
what are the drawbacks of writing to file..? , what temp editor are you creating , why is it temp? not judging , just curious ..
i use SO for a spine and path tool I built , I only have to create save reload once .. after that any changes in the inspector of that object are automatically serialized
for interest sake do you load the saved asset after creating it , habit i formed a while back , might be overkill , cant remember how I came to this pipeline, maybe the examples in the docs? all i know is I always do it for any created assets
directortPath += "/";
string splineDataPath = EditorUtility.SaveFilePanelInProject("Save Spline Data", "newPath.asset", "asset", "enter the name for your new path and save it", directortPath);
if (splineDataPath.Length == 0) return;
AssetDatabase.CreateAsset(target.splineData, splineDataPath);
AssetDatabase.SaveAssets();
AssetDatabase.Refresh();
SplineData splineData = AssetDatabase.LoadAssetAtPath(splineDataPath, typeof(SplineData)) as SplineData;```@left gate im interested to know why your editor SO must be memory only and what the serialization issues are..?
left gate
@cinder cloak I am handling assets and sub-assets. if the object is in memory I can simply do AddObjectToAsset, however you can not do that if it belongs to another Asset. My object in memory is a temp object, as I do not want the changes to be applied across until the user clicks a button
I have to instantiate the sub-asset, re-name it, re-link it to the Saved SO
previously I could simply call CopySerilizedValues then call AddObjectToAsset on any sub-assets. and it would work perfectly
when working with the file object there is also a notable performance difference of a few seconds, when creating/saving the temp obj
cinder cloak
interesting , i have never had the experience of adding same sub assets to multiple assets so I cant give you any input there.
at most the only sub assets i ever add to existing assets is mesh objects, because although they do save as part of the scene without being serialized , you cant create a prefab of that object and export it as a package .. the imported object will be missing the mesh
PrefabUtility.CreatePrefab(finalPrefabPath, targetCast.gameObject, ReplacePrefabOptions.ConnectToPrefab);
AssetDatabase.SaveAssets();
savedPrefab = AssetDatabase.LoadAssetAtPath(finalPrefabPath, typeof(GameObject)) as GameObject;
AssetDatabase.AddObjectToAsset(meshFilterCache.sharedMesh, savedPrefab);
PrefabUtility.ReplacePrefab(targetCast.gameObject, savedPrefab, ReplacePrefabOptions.ConnectToPrefab);
AssetDatabase.ImportAsset(finalPrefabPath);```why not use two linked SO one is the actual final values , the other is for editing?
For example Blender actually does this when you enter edit mode , it duplicates all the data of the object and you actually edit the duplicate, only when you exit edit mode ( same like a user saving ) does it copy the data from the duplicate to the real and trash the duplicate..
it does have drawbacks as well , because if you have a high poly model in the scene and enter edit mode .. it duplicates that hi poly model .. not the best for performance either
but it is a needed evil because for some operations that require mouse movement like translate or scale etc .. you always need to maintain the original value to use in the constant calculation using the current mutating numbers..
i have personally had more issues with doing in memory or scene serialized things, that now I rather always save thing to disc, have not had any issues with that but then again I have never tried to do what you are doing 😉
lucid hedge
@gloomy chasm you could just add a label below the rect right?
and you use onpreviewgui but I don't
I use AssetPreview.GetAssetPreview
and EditorGUI.DrawPreviewTexture
I have a question
So when I implement a scrollview in the editor window
it will only take into account the EditorGUILayout stuff
and not the EditorGUI.DrawPreviewTexture I'm using for the prefabs
how can I implement a scroll view so that it also takes into account the prefab list?
gloomy chasm
@lucid hedge The problem with onpreviewgui is that there is no lighting so they look dark grey instead of white. I will try those two options.
I ended up using GUI.BeginScrollview and GUI.EndScrollview for scrolling.
grim monolith
@lucid hedge what I used on mine is that I calculate how much vertical space it will use and add a Space(height); inside the scroll view
left gate
@cinder cloak sorry for the late reply.
Yes from what I understand that idea I am trying to accomplish. Where the temp object is the duplicate.
Although it would be possible to correctly copy the data back and forth,(I.e. Saving) it's just much more of a pain than having the object in memory.
Having to manage the creation and deletion of assets / sub assets, correctly linking the sub assets. And the performance. It's just much more hassle 😜 especially as the editor is done (would have been much easier if I wrote it this way to begin with)
cinder cloak
hope you getting it sorted 😉
gleaming zenith
Is there a way to rotate a Handles.DrawWireCube(center, size) ?
gleaming zenith
Any more infos about that?
waxen sandal
I mean, you set the matrix and everything is translated/rotated/scaled by that matrix
gleaming zenith
Not working
Handles.matrix = Matrix4x4.Rotate(Quaternion.Euler(0, (float)(Mathf.Rad2Deg * obj.Hdg), 0));
Does not do anything
obj.Hdg is something I can edit live in the inspector
I would expect
Handles.DrawWireCube(
new Vector3(
origin.x,
origin.y - (float) (obj.Height / 2 + obj.ZOffset / 2) + height / 2,
origin.z
),
new Vector3(
(float) obj.Width,
(float) obj.ZOffset,
(float) obj.Length
)
);
to rotate
waxen sandal
That's how I did it when I used it 🤷
With Matrix4x4.TRS that is since I needed both of those as well
gleaming zenith
Nah not working. I probably have to write my own DrawWireCubeWithRotation method
wispy delta
test
weird, i cant share code
even tho im not dming anyone
anyways, here's how i draw a cube with handles. you'll have to change some stuff that's missing, but it may save you some time https://pastebin.com/Q45TK2AC
gleaming zenith
Yeah but actually I don't want handles
I just want to show some debug bounding box
Nothing to edit (just for testing I can do it from the inspector)
wispy delta
thats what this is, there's nothing to grab. its the equivalent of doing it with debug.drawline
there isnt even the handles implementation here, you could change Line with Debug.DrawLine
just has the boilerplate for drawing between the corners
gleaming zenith
ok I check that
Ok it works but it rotates around the center far away.
Doing it like this:
Bounds(new Bounds(origin, size), Matrix4x4.Rotate(Quaternion.Euler(0, -(float)(Mathf.Rad2Deg * obj.Hdg), 0)));
Only on the object when hdg = 0. When hdg = PI its at maximum distance
wispy delta
you need to do Matrix4x4.TRS it's expecting a full transformation matrix
gleaming zenith
ok
wispy delta
offset the position in the matrix
gleaming zenith
it got even further away 😦
wispy delta
show me the code that calls the method
and your version of the method if you made significant changes
gleaming zenith
wispy delta
set the center to Vector3.zer, the offset is done through the matrix
gleaming zenith
the offset should always be zero
I just want to rotate the object around its own axis
wispy delta
where in the scene do you want to draw the cube?
gleaming zenith
At the origin position
with size size
with rotation Quaternion.Euler(0, -(float)(Mathf.Rad2Deg * obj.Hdg), 0)
Sorry not too much into vector math^^
wispy delta
no worries. try
Bounds(new Bounds(Vector3.zero, size), Matrix4x4.TRS(origin, Quaternion.Euler(0, -(float)(Mathf.Rad2Deg * obj.Hdg), 0), Vector3.one));
gleaming zenith
@wispy delta You're a king^^
I would've just tested around with the parameter otherwise^^
wispy delta
haha glad to help. if i wasnt playing anthem rn id try to explain matrices better
gleaming zenith
it's ok. Keep looting and leveling^^
wispy delta
ok im switching games so i can try and explain it rq.
multiplying a point by a transformation matrix returns a point relative to that "transform"
so in ur case you are creating bounds at 0,0,0 but then making that 0,0,0 relative to origin via the matrix. the same applies to the rotation and scale.
It's how child transforms in the scene have relative positions, rotations and scales.
gleaming zenith
Ok yeah I will work with vector math in the future so I probably get to that anyway^^
barren siren
guys, im new, need some help, what does private, public, float and private float mean?
wispy delta
those are "access modifiers", they just define what scripts have access to the variable or function. private means they can only be accessed from within the object they are defined in. public means they can be accessed from anywhere
gleaming zenith
I think you should go through the basics of programming first
wispy delta
^
gleaming zenith
Don't try to rush this stuff as it takes time
first video i found about basics
gleaming zenith
As programmer most of the time
As when you program in 3d you only have to add one more axis
math might get more complicated
but just for beginning I personally think 3d and 2d does not much differ. I saw many people think 2d is easier but then were suprised that 3d isn't much harder
It depends on how fast you understand stuff especially thinking in a 3d / 2d perspective
wispy delta
i started in 3d before unity had 2d mode. it's really not much harder if you have any familiarity with x,y,z. If you have zero experience with any 3d applications, 2d might be a tiny bit easier
barren siren

Hello everyone !
Do you have tips, video, ressources to learn how to use the new UIElement system, the new way to do editor script ?
I found this: https://docs.unity3d.com/Manual/UIElements.html
But it's still tagged as experimental and it's rough to read.
wispy delta
not a lot of resources on it yet, but the examples along with a basic understanding of html/css should be enough to get started
leaden oar
❤
Yes there is not so much things about it right now. That a bit sad for those who want to learn more about it.

unity doesn't like to invest too much time into making learning resources while things are experimental b/c they'll have to recreate all of them if anything significant changes

Unity was always pretty slow when it comes to documentation. You can learn most about new stuff in videos

Does anyone know how I create multiple scenes additively in the editor? I always get InvalidOperationException: Current mode does not support additive creation of new scenes. and I don't find anything useful to it in the internet.
I want to create multiple scenes at once (or with delay I dont care) that have different purposes
leaden oar
@gleaming zenith can you precise your problem ?
Creating scene and adding them additively to the current scene are two different things
gleaming zenith
In the Editor i want to create two scenes at the same time via
EditorSceneManager.NewScene(NewSceneSetup.Empty, Single);
EditorSceneManager.NewScene(NewSceneSetup.Empty, Additive); // throws exception
#pseudoCode
leaden oar
The process to create a scene and add it additively you must:
- Create the scene
- Save it as an asset
- Add it to the list of scenes in build in the build settings
- Instantiate it additively
scenic elbow
@gleaming zenith are you trying to do it in play mode?
gleaming zenith
@scenic elbow No this is an editor script.
@leaden oar I'm going to give this a try tomorrow. I probably have to save it as asset as I cannot have multiple unnamed scenes?
scenic elbow
weird, thought maybe the error implies it's not supported in either edit/play mode
should be in edit tho
leaden oar
@gleaming zenith You probably can't indeed
@gleaming zenith
Create
Scene newScene = EditorSceneManager.NewScene(NewSceneSetup.EmptyScene, NewSceneMode.Additive);
Save
EditorSceneManager.SaveScene(newScene, "Assets" + path + _name + ".unity");
path: "/Scenes/";
Add to build settings
public void AddSceneToSettings()
{
List<EditorBuildSettingsScene> newSettings = new List<EditorBuildSettingsScene>();
newSettings = EditorBuildSettings.scenes.ToList();
EditorBuildSettingsScene sceneToAdd = new EditorBuildSettingsScene("Assets"+path + Name + ".unity", true);
newSettings.Add(sceneToAdd);
EditorBuildSettings.scenes = newSettings.ToArray();
}
Load Scene
EditorSceneManager.OpenScene("Assets" + path + _name + ".unity", OpenSceneMode.Additive);
path: "/Scenes/";
Bonus, remove scene
public void RemoveScene(string _name)
{
if (SceneManager.GetSceneByName(_name).isLoaded)
{
EditorSceneManager.UnloadSceneAsync(EditorSceneManager.GetSceneByName(_name));
}
}
Just extract that from one of my project. Should work 😃
gleaming zenith
I would have get that my own :p I already got that for in parts but not in combination with multiple scenes. Thank you anyway^^

Hey there. I'm having trouble finding actual documentation on nested prefabs.
It seems like PrefabUtility.IsAnyPrefabInstanceRoot(..) should return true for roots of nested prefabs, even on an instantiated copy of the source prefab.
i.e. if the first child of a GameObject is the root of a nested prefab, these asserts would pass:
GameObject prefab = LoadAsset(..);
GameObject nestedPrefabRootInPrefab = prefab.transform.GetChild(0).gameObject;
Assert.IsTrue(PrefabUtility.IsAnyPrefabInstanceRoot(nestedPrefabRootInPrefab));
GameObject instance = GameObject.Instantiate(prefab);
GameObject nestedPrefabRootInInstance = instance.transform.GetChild(0).gameObject;
Assert.IsTrue(PrefabUtility.IsAnyPrefabInstanceRoot(nestedPrefabRootInInstance))
Is this understanding correct?
drowsy maple
It looks like that's incorrect. Experimentally, IsAnyPrefabInstanceRoot(..) only seems to work on objects returned by PrefabUtility.InstantiatePrefab(..).
I'm trying to make bulk changes to the non-nested parts of prefabs, and edits to prefabs instantiated this way cannot be saved, so this is inconvenient.
I can try to solve this by iterating both the PrefabUtility prefab and an instantiated prefab at the same time, but that approach won't work well as the number of prefabs in my project increases.
Is there a better way to determine what part of an editable prefab is in nested prefabs, or a way to save changes to a PrefabUtility prefab instance?
drowsy maple
My problem was trying to use AssetDatabase.LoadAssetAtPath(..) and PrefabUtility.SavePrefabAsset(..). Using PrefabUtility.LoadPrefabContents(..) and PrefabUtility.SaveAsPrefabAsset(..) made this much simpler.

@leaden oar FYI: I just checked it. You have to save the scenes before you can add more "temporary" scenes. It's not possible to have multiple "unnamed" scenes

is it possible to draw an objects custom editor inside of an editorwindow? my attempts have been crashing the editor so far 😛

I use Editor.CreateCachedEditor
Then you can just call OnInspectorGUI on the ref'd Editor. Just remember to dispose it @worthy swan

@wispy delta ah thanks, now I'm drawing a propertydrawer instead which works fine too 😄

I'm trying to use Unity's ReorderableList class, but can't seem to be able to, well, reorder the elements.
Items clicked don't get highlighted so I can't really do anything other than to add and view items.
I'm using it on a custom inspector of a scriptable object.
Any ideas?
wispy delta
Not sure. Post whatever code you can and I'll see if anything looks funky
If you add three backticks on either side of the code it'll give it code formatting. A lil easier to read
Code
I take it it's not those ><
wispy delta
Yeah not single quotes
dusky plover
{
drawElementCallback = drawAction,
};
m_ActionList.DoLayoutList(); ```👌
dusky plover
There we go
Basically it's just the most basic code. But I'm getting this awful feeling that it's not working because it doesn't support selection for non-serialized property lists? =\
wispy delta
So i think the issue is you are recreating the list Everytime it needs to be drawn which is likely messing up any persistence. Create a field for the list and call the constructor in OnEnable. Then you can just call DoLayoutList in OnInspectorGUI
Also setup the delegates in onenable
wispy delta
Np 👍

@dusky plover Btw don't do hungarian notation. It's ugly.

You either provide their access_ or their types in lowercase and the rest pascal case

Ah, yeah haha I feel like the only people who use that notation are people over 30 years old, or students of people who are over 30 years old. But at the end of the day it doesn't really matter 🤷
grim walrus
Depends where you work. Some places have their own managed standards that require you to use it
wispy delta
Yeah, as long as everyone who's working on a project can agree to a convention it's fine.

I just do variableName for fields and VariableName for properties and statics. Havent really run into any issues doing that

@reef crane No you cannot use a personal license for work at your company. What's the purpose of company licenses then?
@visual stag Nice to hear that they're finally doing something in a standardized way 😄 Where did you hear that? I think this can cause many issues if not done correctly by unity because of the serialization and refactorings (you know)
@grim walrus Rider is defenitly worth the money!

A Personal license is an option for private individuals who purchase a license with their own funds, and solely for their own use. Personal licenses are not to be purchased, refunded or in any way financed by companies.
Yes, you can use your personal license at work as well as at home. You can use it working on your personal projects as well as your projects in your company. Our EULAs do not restrict this.

"free" VS license?
gleaming zenith
But you're only allowed to use that if your Company does not make more then 500,000$ sales / year
reef crane
Yeah, the "refund" terminology seems like it's there to block you from buying it personally, using it at work, then having your company give you a bonus to the same value of a license
grim walrus
"free"
allegedly we make more then that per year
Projects go around £80-100k
But the new product/project thing has been £750k and another sat around £2.5million
Our studio as a whole gets like 10% of that because this company is ass
But its still the company that has the revenue

Any reason that GUILayoutUtility.GetRect passing GUILayout.ExpandWidth(true) doesn't expand the width across the entirety of the area?
fast helm
Upgrading from 2018.1 to .3, have hundreds of models that now have a "Fix Now" for blendshape importing. We use AssetImporter scripts to handle fixing this kind of stuff usually, but for some reason the bool that's associated with it in the ModelImporter class, bool legacyComputeAllNormalsFromSmoothingGroupsWhenMeshHasBlendShapes is set to internal so we can't auto-fix this issue with our importer (without whipping up some reflection) and have to manually go through the import settings. Just curious if there is some reasoning to having that property hidden from scripters before I go ahead and reflect it... The GUI fix button code merely set it to true, so I'm not seeing any special reason for it being so.
waxen sandal
You can probably access it with a serialized object
fast helm
That's not really accessible from the context of AssetPostprocessor and ModelImporter class. I can access it fine using a few simple lines of reflection, was just curious if there was an editor dev here that could give some insight into a decision like that
waxen sandal
Can't you make a SO from the ModelImporter?
I think I've done that before to access a few things
fast helm
Both of the related editor class for the ModelImporter are also internal. Not really looking for a solution here, I have one, just wondering about why the restricted access.
nova scarab
Are foldouts width restricted or something?
grim monolith
What you mean with restricted?
nova scarab
No matter what width I specify in the size, it stays the same. I am using a custom GUI style but that style has "fixed width" set to 0 and "Stretch Width" to true.
EditorGUI.Foldout(new Rect(nRect.x, nRect.y, 1000, nRect.height),descriptor.Expanded, descriptor.Description, true, RunicSystemStyle.Instance.ListItem);

Override the style should fix it

When I instantiate a new prefab via var instance = (GameObject)PrefabUtility.InstantiatePrefab(prefab, scene) in the editor and trying to set its parent via transform.SetParent(parentTransform) or transform.parent = parentTransform it does not work. Anyone knows why?
Doing a "delayed" invoke seems to fix this issue. Again some strange Unity behaviour
Delayed in this case means saving all instances in a list and iterating over them as soon as all prefabs are instantiated. WTF
lucid hedge
Question
this error
I 'kind of' know why I'm getting it
but not sure how to fix it
it has to do with me changing GUI elements at the wrong time
the error is point me to this
in OnGUI I'm doing this
{
selectedPrefab = prefabs[i];```so assigning something to 'selectedPrefab'
but I'm also doing this in OnGUI
if (selectedPrefab != null) selectedPrefab.displaySettings();
so during the mousePosition event I'm assigning something to selectedPrefab, making it not null, calling displaySettings() which adds GUI elements
so how would I fix this?
nvm fixed it
by doing so Event.current.type = EventType.Layout checks
wispy delta
@gleaming zenith is there an error?
gleaming zenith
@wispy delta No it's just not working
@wispy delta Like it ignores the calls at all
wispy delta
But adding a reference to the object in a list and setting it's parent through there works?
Are you anything between instantiation and list iteration?
gleaming zenith
I instantiate them and want to set their position and parent directly afterwards. But none of both work (order doesn't matter as well)
As I said the workaround works. Also commented with a WTF Unity
wispy delta
Very strange. I haven't used the prefabutility version of instantiate. Maybe you could try the normal instantiate method and just see if it works @gleaming zenith
Just to see if the problem has to do with prefabutility
gleaming zenith
that might work yeah but I need the InstantiateAndConnect feature
dusky plover
So another ReorderableList question. Anyone has an idea how to enable multi-element selection? And if copy/pasting is in any way possible as a built in option?
wispy delta
You'd have to handle multi selection on your own. It's not too hard I should think. You can plug into the selection delegate and check if the shift key is pressed via Event.current
@dusky plover same for copy pasting. You'd have to handle that yourself
dusky plover
Yea, already implemented copy paste since I asked haha
Multi selection is a bit more worrying though, as it has some edge cases with the inherent drag and drop of the elements.
wispy delta
Have you tried only doing it if the mouse delta is below a theeshhold?
dusky plover
I meant about the part about dragging a group of elements rather than just 1 at a time.
wispy delta
Ah I see
dusky plover
Guess there's no getting around figuring that one out though 😃
wispy delta
Pretty sure someone figured it out on github
I forget the repo name tho
I believe it's this ^
dusky plover
Yea, and it looks good, but I have a typing limitation in my code that I can't use a serialized property for these, and all the extensions that I found many people do only support the serialized property interface and not the list one.
wispy delta
Yeah, no need to use his system but maybe you can see how he does element selection

hey guys, is there a way to store values in an array in the editor/inspector script?`
wispy delta
Just define an array in a monobehaviour or scriptableobject that is public or has the serializefield attribute
@meager copper
meager copper
@wispy delta so i have to create the array in the normal game script, even if i just need them for the editor?
wispy delta
If you just need it in the editor create a scriptableobject that holds it and load it from the editor
You dont have to load the scriptableobject at runtime
meager copper
maybe i should give u more input, i think there is a better solution, i using a array so save some UI data for a char creator menu, and if the user edits the panel count to a lower count, it should save the values that will be deleted in a 2nd array, if the user set the size up again, the old values shoudl be displayed
visual stag
If you don't need it persistent put it in the Editor. If you need it persistent put it on a ScriptableObject or on the inspected Object. If you did put it on the Object you could exclude it with preprocessor ifs

how do you edit the inspector for scriptableobjects?
wispy delta
What do you mean? @errant finch
You can create a custom editor in the same way you would for a monobehaviour
errant finch
I just realized what I was trying to make an editor for what not actually a scriptable object, but rather a field on the object
not good
wispy delta
I'm still not very sure what you are stuck on, but if you want a custom Editor for a variable use a PropertyDrawer
errant finch
k wait let me explain
So I've got this scriptable object which basically holds an ability
it has a public variable called Selector
and this selector has a whole ton of properties
I want to make a custom inspector for the selector specifically
so it shows up on the scriptable object
is that a thing I can do?
I want to edit the region in yellow
wispy delta
Yes use a property drawer
errant finch
I have never done editor scripting
can you explain it like I'm 5
oh wait do I just extend from propertydrawer as opposed to editor?
and do custompropertydrawer?
wispy delta
You cannot create a custom editor for arbitrary classes and structs, only monobehaviours and scriptableobjects. Custom editors are for inspectable things. You aren't inspecting the SelectorData you are inspecting an object that encapsulates a selector data instance. If you want to override the default way Unity draws a serializable class in an inspector you must create a property drawer for it in the same way you'd create an editor for a monobehaviour or scriptableobject
It's basically the same thing as a custom editor, but it's for arbitrary classes. Look it up and you'll find plenty of examples
errant finch
ya I found some
ty
wait just to make sure
do propertydrawers needs to be in an Editor folder?
wispy delta
Yes
Any code that uses anything in the UnityEditor namespace needs to be in the editor folder
errant finch
doesn't seem like anything I do changes the inspector
ooooh wait
nvm
errr is there any better way than giving a string to FindPropertyRelative?
that's pretty gross
wispy delta
It is a serialized property so strings are to be expected

Gross is the way to go

very messy but this does what im guessing you want
visual stag
Oh is it highlighted but my iPad doesn’t do it
errant finch
oh um, I'm doing a propertydrawer
wispy delta
You can always sacrifice the ease-of-use of serialized properties/objects and do all the undo/multi selection support yourself. It'll be more explicit and you can modify properties instead of fields, however youll likely end up using a ton of linq and writing a ton of repetitive code
Yeah there isn't code formatting on mobile for some reason

it's just some things I only want to show up during certain conditions

Property drawers are just editor styling for fields that use EditorGUI.PropertyField to draw
wispy delta
Check out my snippet above if you are using serialized properties for the enum @errant finch
errant finch
oh shit boys
I think it's doing a thing
oh here's a question
how do you represent a sprite as it's actual sprite
instead of the name
you know what I mean?
which method
dawn thistle
like... do you want to draw a sprite in the inspector?
wispy delta
DrawRect with a guicontent that holds the texture I think
Haven't had to do that before
Nope, not that
visual stag
Look at the source for the inspector that draws the control you want https://bitbucket.org/Unity-Technologies/ui/src/0651862509331da4e85f519de88c99d0529493a5/UnityEditor.UI/UI/ImageEditor.cs?at=2018.3%2Fstaging&fileviewer=file-view-default
The source code for the editor is your best friend
wispy delta
You are setting it to null constantly
Assuming the property has a serialized SelectionType field you'd wanna use that
wispy delta
What line does the error point to, if any
errant finch
this is very unintuitive
the editor one makes significantly more sense
whats my version of "target" here?
still not working
error on the enumpopup line
wispy delta
The property is your target
wispy delta
Probably won't fix the error, but you are completely sidestepping the serialized property. I'd advise you accept the sin which is using strings, otherwise you might as well not use serialized properties. I'm on mobile so I don't want to type up how serialized properties should be used. Just look at any of the editor source or documentation
You'll notice 99.9% of editor code, written by Unity, that draws the editors you use every day, use serialized properties and strings
wispy delta
Look at examples or documentation. You're asking me to reexplain something that you can find on your own easily
digital void
First of: in propertydrawers you cannot rely on the GUILayout-mechanisms, so your enum-GUI wont work at all right now. You have to do layouting yourself based on the provided position-Rect (you can set a requirement on height for this rectangle through overriding GetPropertyHeight). Just manipulate the position rect and/or create new rects as needed within OnGUI.
In terms of using serializedProperty correctly, you're best of trying to avoid casting the property back to it's original type, and rather work on the raw serialized data:
var selectionTypeProp = property.FindPropertyRelative("selectionType");
//either of these should do:
UnityEditor.EditorGUI.PropertyField(someRect,"Some Label", selectionTypeProp);
selectionTypeProp.enumValueIndex = UnityEditor.EditorGUI.Popup(someRect, "Some Label", selectionTypeProp.enumValueIndex, selectionTypeProp.enumDisplayNames);
then to do the checking you can do this:
switch((SelectorData.SelectionType)selectionTypeProp.enumValueIndex) {
case SelectorData.SelectionType.AoE:
//doStuff
break;
case SelectorData.SelectionType.AreaPick:
//doStuff
break;
//... etc.
}
I think it would be really cool if I could override hover-tooltip GUI. It would let me have super informative in-editor documentation. If I was a better programmer I could do something cool like make hovering over a property show it's markdown documentation.

As in do more than show text?
I haven't yet done tooltips in UIElement, but if they are limiting I plan on making something to inject modifications into them
So remind me in 2 weeks time :P
wispy delta
Ok haha
I wanna learn more about this injection you are doing. Sounds really powerful. Does it only work if the gui being injected into is drawn with UI elements?
visual stag
No, it would only work by injecting uielements
My kittens thing could put cats in tooltips
So I figure I can adjust the tooltip window panel size and put my own stuff in there
It would be painful to get the hover event and to associate gui with it in imgui though

hey guys may u can help me, i have a dropdown in a custom inspector and i use a private bool for it
with the attribute [SerializeField], i dont change the value in the code (just with the foldout click) but if i switch the gameobject its get false again, how can i save the last state of the bool?
forest vortex
so you want the editor to show the same value for the foldout, but no matter which object you're editing?
mental wind
if that's what you're looking for, you should make it static
meager copper
it should keep the value if i open all things in the treeview, and change my object just to came back to it, it should be still open, actual the bool gets false and the dropdown closes
static will help?
mental wind
oh i see

oh! great lol
mental wind
well you were trying to do something different than i thought but i'm glad that worked lmao
meager copper
😄
omfg i tried this since i think, 45 minutes
didnt thought about to declar it as static
mental wind
yeah i guess static variables in custom editors are serialized more reliably than other ones
mental wind
no prob
visual stag
Static variables are not serialized, but are persisted. It will mean all the inspectors share the same value. If you wanted it per-object you were probably not dirtying with an Undo or SerializedObject functionality and it never registered the change
craggy sedge
Note: static variables are only persisted until a script recompile, or until you enter/exit play mode
mental wind
gotcha. interesting! makes sense that static variables are persistent.

wispy delta
I'm getting an error saying I shouldn't be accessing the targets array from within OnSceneGUI, but I'm not touching it anywhere. Any ideas?
It's triggered when i click on an object with handles whose colors are loaded from a scriptable object singleton. ie: if it doesn't exist, one is created in the project. The error only occurs when one has to be created.
red gorge
@wispy delta I would try to ensure the settings asset has been created before OnSceneGUI is run. Perhaps in OnEnable(). Creating the asset in that method must be accessing the targets array.
wispy delta
Bummer. Guess I'll have to add EnsureSettings()to roughly 40 custom editors
red gorge
Is there really a need to dynamically create the asset?
wispy delta
When else should I create it. Lazy instantiation seems fine?
red gorge
If it just exists in your project, you don't need to worry about that
craggy sedge
What if you had one of those InitializeOnLoad tags on a function in the class that creates it? So it gets created on script recompile if it doesn't exist already
I think at that point it would run even before OnEnable
wispy delta
I should consider that @craggy sedge, but that would present an issue if the user accidentally deleted the asset. It wouldn't be recreated until the next time code is recompiled. And it's in an asmdef, so tmk they'd specifically have to change my editor code since it doesn't have any dependencies. For what it's worth, this is a tool that I plan to sell. If I was the only one using it I wouldn't mind recompiling
red gorge
Another option would be setting a flag that the asset needs to be created in OnSceneGUI and using a default value, then creating the asset in the editor update loop if the flag is set
Probably prone to some visual weirdness if OnSceneGUI isn't called often though
wispy delta
I think the best option may be to create it in an InitializeOnLoad method, and if the edge case where the asset is deleted occurs my singleton may throw an error when it creates the asset but who cares.

How do I move a menu-item "folder" further down it's list of menu-items. I know how to change the priority of the "leaf" item, but not it's container item
craggy sedge
I think the priority is set as a 'whole', if that makes sense
So set the priority much higher on the inner items, and it should move the folder down
You may have to restart Unity to see that effect
wispy delta
That did it, thanks. Would be cool to see something similar to the Script Execution Order window. Might be overkill, but everyone's menu items are scattered amongst the Unity ones.

@dim walrus I haven't really gotten into the new prefab stuff but this might help https://docs.unity3d.com/ScriptReference/Experimental.SceneManagement.PrefabStageUtility.GetCurrentPrefabStage.html

Is there a way to make a button fill a percentage of the available space in the inspector? What I want to do is make a horizontal row of three buttons all 33.333% wide no mater the text inside them.
that way multiple rows of three buttons would line up
wispy delta
@craggy dock There may be a better way, but you could reserve the total space you want the three buttons to fill with GUILayoutUtility.GetRect. Split the returned rect into three parts and draw your buttons inside them.
This should give you a container rect to split that stretches to fill the width but has a predetermined height
var containerRect = GUILayoutUtility.GetRect (1, buttonHeight);
Thanks @wispy delta !
wispy delta
np, lemme know if it works 😃
craggy dock
Ok I have been reading the docs ect... how do I split the containerRect put the buttons in it?
wispy delta
@craggy dock
int padding = 2;
// Get the container rect and reserve it's space in the layout
var container = GUILayoutUtility.GetRect (1, 50);
// Set the left, right and middle rects equal to the container to start
var leftRect = new Rect (container);
var middleRect = new Rect (container);
var rightRect = new Rect (container);
// Calculate the two x positions that create the three-way split
// one third across
var middleLeft = container.xMin + container.width * (1f / 3f);
// two thirds across
var middleRight = container.xMin + container.width * (2f / 3f);
// Make the right side of the left rect flush to the left split
leftRect.xMax = middleLeft - padding;
// Make the middle rect flush to the split on it's left and right
middleRect.xMin = middleLeft + padding;
middleRect.xMax = middleRight - padding;
// Make the left side of the right rect flush to the right split
rightRect.xMin = middleRight + padding;
// Draw the buttons on their rects
GUI.Button (leftRect, "Left");
GUI.Button (middleRect, "Middle");
GUI.Button (rightRect, "Right");
Wow thanks @wispy delta Unity editor GUI scripting is a whole different animal than the WPF and XAML I do for my day job.
visual stag
Come to UIElement in 2019 and then It’ll be very familiar
wispy delta
@craggy dock Np. It's weird but once you get a basic handle on the weirdness it's fast to get stuff up and running
If I ever need help with WPF or XAML I'll ping you haha. I've never touched those in my life

@wispy delta
wispy delta
very nice 👍
craggy dock
thanks man!
wispy delta
happy to help 😃
craggy dock
those unaligned buttons were driving me nuts! Now to fix the rest of my buttons lol.
wispy delta
@craggy dock If you want splitters that are a solid color/line I've got a method that makes it easy to draw. (vertx actually wrote this, but I tweaked it a bit) If you set wideMode to true the splitter will stretch completely across whatever window it is drawn in rather than it's enclosing layout rect.
public static void Splitter (float padding = 3f, bool wideMode = false)
{
GUILayoutUtility.GetRect (1f, padding);
var rect = GUILayoutUtility.GetRect (1f, 1f);
GUILayoutUtility.GetRect (1f, padding);
if (Event.current.type != EventType.Repaint)
return;
if (wideMode)
{
rect.xMin = 0f;
rect.xMax = Screen.width;
}
var color = EditorGUIUtility.isProSkin ? new Color32 (30, 30, 30, 255) : new Color32 (153, 153, 153, 255);
color.a = GUI.color.a;
EditorGUI.DrawRect (rect, color);
}
If you like your splitters, that's fine - just thought I'd show you another easy option
Looks like this in wide mode
craggy dock
oh that is nice!
dim walrus
@visual stag Thanks that's exactly what i was looking for
peak lava
@craggy dock sorry for the ping. But do you use any packages in wpf, like Fody, for auto triggering property changes?
gloomy chasm
@craggy dock If you want another way to do it. I do GUILayout.width(Screen.width / 3)
wispy delta
You could do that but I don't believe you can do padding easily
craggy dock
I ended up making a function that will return me a row with how ever many columns I want even does padding! Thanks @wispy delta for the inspiration.
private List<Rect> GenRow(int columns, int rowHeight = 50, int vertPadding = 2)
{
List<Rect> row = new List<Rect>();
int padding = 2;
//Vert Padding
GUILayoutUtility.GetRect(1,vertPadding);
// Get the container rect and reserve it's space in the layout
var container = GUILayoutUtility.GetRect(1, 50);
float colWidth = (container.xMin + container.width) / (float)columns;
for(int i=0; i<columns; i++){
Rect tmp = new Rect(container);
if(i>0) tmp.xMin = i * colWidth + padding;
tmp.xMax = (i * colWidth) + colWidth - padding;
row.Add(tmp);
}
return row;
}
to use it you just call
List<Rect> row = GenRow(3);
GUI.Button(row[0], "B1");
GUI.Button(row[1], "Button2");
GUI.Button(row[2], "Test B3");
Buttons are so so so much tidier than before!

You would need to change gui style richText property GUI.skin.GetStyle("HelpBox");
zealous ice
var style = GUI.skin.GetStyle("HelpBox");
style.richText = true;
EditorGUILayout.HelpBox(text, MessageType.None);
```Like that? Never knew there was such optionI've added one line to make it "safe"
var style = GUI.skin.GetStyle("HelpBox");
style.richText = true;
EditorGUILayout.HelpBox(text, MessageType.None);
style.richText = false;
I just wanted to write that you can restore it to be safe ;d
zealous ice
:P I was faster
digital void
alternatively you can also avoid editing the skin altogether by doing something like this:
public static readonly GUIStyle richTextHelpBox = new GUIStyle("HelpBox")
{
name = "richTextHelpBox ",
richText = true
};
// ...
public static void NonFocusStealingHelpbox( string text, MessageType msgType )
{
//HACK - helpbox steals focus when disabled/enabled (i.e. if it's drawn within an if-block), this will prevent it
GUILayout.Label( EditorGUIUtility.TrTextContentWithIcon(text, msgType), richTextHelpBox );
}
then again, you might not want to define new static styles all over the place, but I still found this one very useful as it also solved an issue for me with focus-stealing helpboxes earlier
gloomy chasm
Is there a way to enter Prefab Mode from script?
wispy delta
@gloomy chasm I believe you want PrefabUtility.LoadPrefabContents() or PrefabUtility.LoadPrefabContentsIntoPreviewScene()
gloomy chasm
Hmm, thanks @wispy delta.
What I was hoping to do is use the Prefab Mode view to edit a scriptableobject with some handles. But I guess I would be surprised if that was really possible.
wispy delta
ScriptableObjects arent prefabs so that wouldnt really make sense
You could make a script on a prefab store a unique copy of a scriptable object if you wanted to, but at that point you're kinda sidestepping the entire point of scriptable objects
gloomy chasm
Yeah, I have a pretty niche use for it.
Using scriptable object as a 'mesh shape' that I extrude along a path. So the scriptable object has verts that I want to be able to move around
wispy delta
Hmmm. If the shape's points are in 2d I'd consider just making a custom window for moving and adding points
You could probably even do 3d in a custom window, but I'm not familiar with how
gloomy chasm
I was wondering. How does one make a custom Handles.CapFunction?
Mostly asking for the functionality of the drawing settings in it. So I could use Handles.FreeMoveHandle that had a custom 2D image instead of the normal ones.
wispy delta
It's a delegate so just make your own function with a matching signature
If you scroll up a bit, @lucid hedge and I made a simple "hack" to draw our own controls over a previously made cap
gloomy chasm
I was figuring it was a delegate. I'm sorry I don't understand how to tell it what it looks like though.
I couldn't find when you and Alexander were talking and figured this out. Maybe I didn't scroll high enough?
wispy delta
@gloomy chasm when i don't know what arguments a delegate requires i just create an anonymous method and add arguments until the errors go away. Then I can mouse over the temporary arguments, see what type they are, and rename them
So i'd do
handleCap = (a) => {}
If there's an error
handleCap = (a, b) => {}
If there's still an error
handleCap = (a, b, c) => {}
repeat until no error and then you can hover over to see the argument types
There's definitely a better way to see delegate types out there. But this gets the job done for me 🤷
in the case of the cap function the signature is (int id, Vector3 position, Quaternion rotation, float size, EventType eventType)
gloomy chasm
@wispy delta What I am wanting to do is instead of draw say a cube, or a circle. To draw a custom image/icon.
indigo briar
Hi. I have a little problem: My Unity does not detect my skripts as mono behaviour anymore.
forest vortex
what makes you say that
if you mean the text view on the right, that's just a preview of the contents, that's normal
if you want to edit the properties, the scripts have to be on a gameobject in the scene, or on a prefab in the assets
you can't get the component menu from clicking on the script directly.
indigo briar
yes. but they works no more. the error message is up right.
wispy delta
you have a variable with the same name as the class
forest vortex
yeah i couldn't see the error since it was so tiny
but that error usually means the class name has a problem
it can also happen if your class name has a space in it, or doesn't match the filename of the file
but the error is clear there's a variable named spawn inside Spawn Class
it's the red error lower left that matters
wispy delta
@gloomy chasm you'll likely have to delve into the Graphics class
gloomy chasm
Oh, okay.
forest vortex
until you fix all red errors, it can't compile
indigo briar
what can be wrong at the file names? they dont have a space charakter. they have worked before, but now not.
forest vortex
it's not filename
in this case
you have a class named "Spawn" and it contains some variable named "Spawn"
you can't use the same variable name as a class name
unless it's a reference to that class heh
when you open Spawn in Visual studio it should highlight the problem.
indigo briar
ok, but the other scripts dont work too.
forest vortex
yes need to fix each one
that's what the console is for
to show you all the warnings and errors
for now just worry about errrors
indigo briar
Assets\Scripts\Spawner1.cs(41,49): error CS1061: 'GameObject[]' does not contain a definition for 'Lenght' and no accessible extension method 'Lenght' accepting a first argument of type 'GameObject[]' could be found (are you missing a using directive or an assembly reference?)
forest vortex
Lenght is probably a misspelling for Length
and not sure about the other
just open the files and the problem wil be in red
or i guess that is all one error, i thought it was two at first lol
wispy delta
if you double click an error in unity it will take you to the line where the error is. double check your spelling and you'll fix a lot of errors
indigo briar
moving and killing are the scripts, that are assigned to the gameobject "Ghost". They have worked before few days.
ok, i wlill try that.
forest vortex
well someone must have changed them because they have misspellings and other errors that would never compile
indigo briar
Thank you very much, guys, IT WORKS NOW!!!!
visual stag
That's good 😌 next time #💻┃code-beginner is the correct place for such questions. This channel is for extending the Editor 👍
indigo briar
Ok.
wispy delta
When I double click an object field to go to that object I get an argument exception. Here's the error: https://pastebin.com/jJ3gQh8b
The error takes me to a EditorGUILayout.Space() call right after I draw the toolbar buttons.
These are the toolbar buttons drawn right before the error
The only thing I can think is that the toolbar is the first time a Scope is used after drawing the reorderable list. Would an exception in the list gui cause a scope to not be disposed or something?
But to my knowledge there aren't any scopes drawn in the list so idk
visual stag
It’s the classic pain that is returning in the layout phase before the repaint
If you return before all the controls are layouted when it comes to repaint a layout will not have been registered for the following controls
Sometimes this means you don’t return in layout, other times it means you if else instead of returning... it’s a weird scenario
I think there is also an EditorGUI.ExitGUI or something similar that is undocumented that is intended for use in this circumstance
If you understand the issue as I’ve described it you can probably find a solution that works for your specific code
(I’m currently on a plane so I can’t be of more help lol)
wispy delta
Thanks for the explanation! I guess I'm still confused as to why double-clicking the object field causes the error, but manually selecting the game object (that double-clicking the field would have selected) doesn't? I guess it means the error issue is in the property field for the list element?
visual stag
I’m not sure without a deeper dive, sorry. But it should be to do with an incomplete layout phase, or a mismatched one. Sometimes I’ve had circumstances where I feel it’s unity’s problem and I just suppress the error sadly.
But more often than not it is me that’s the problem of course
wispy delta
Yea I'm sure it's something I've done wrong. It must have been a change I made relatively recently because it hasn't been a problem till today. I'll look through my commit history and see if anything looks fishy. I appreciate the help as always 😃
visual stag
As long as you have that concept of two passes that I’ve previously mentioned. One being layout, the other repaint. And understanding that guilayout calls need to be the same across both you should be able to understand the issue
No worries 😃
wispy delta
I'm pretty sure I understand it - tho I'm not sure of how often that would come in to play. Is OnInspectorGUI called twice and all the Unity methods do layout stuff in one and drawing in the other? If so, I can't think of a scenario in which anything would change between calls.
visual stag
If you have a button that adds content, or returns, or removes
You may get the down event in layout, then modify the collection you're drawing the gui over, then repaint happens and there's a difference
wispy delta
I see. It would make more sense to me for any input to only be read in the draw phase, but I have a limited understand of the system and I'm sure there's a good reason for it not to be
wispy delta
Long story short, the problem was I foolishly added a try catch (Exception e) around the list gui and there was an important error happening in there that I didn't know about.
Short story long, I'm running into issues with list serialization again. @visual stag we were able to detect changes made by the drag n drop gui and force the serialized object to update since all that code was in the Deformable editor, but now I'm running into the same issue when adding elements to the list from an external custom window. I don't have access to the Deformables custom editor from the window, so I can't force it to update. Right now I'm just doing this brute force solution and the problem seems to be solved
serializedObject.SetIsDifferentCacheDirty ();
serializedObject.Update ();
deformerList.DoLayoutList ();
Is this bad?
visual stag
Beautiful. My inflight WiFi ended and now I'm on a bus. Hm, seems not great. I'd try a bunch of stuff to attempt to trigger the change, or perhaps make a static bool where you can dirty it for the editor
wispy delta
Ok, will do. This whole list serialization has really becoming *become (I literally cannot spell) a pain in the ass. Is it worth filing a bug report over, or do you think it's intrinsic to how the whole thing works?
visual stag
If you can make a good test case, yeah, definitely. If it's not a bug it'd be great for the devs to explain the exact issue
wispy delta
Ok cool. I'll make a reminder to myself to put together a simple test project to make it easy to see.
visual stag
I have multiple simple bug reports that bounced back at me because I haven't provided code, and some are too complicated. So whilst the QA people are great I feel without a succinct report and example the pain of reporting can be great
wispy delta
Yea. I'm worried about this one b/c I understand the issue but it's kinda hard to explain
visual stag
I usually make an editor windows with multiple buttons, one that's how it should work, and the other with the correct code but the broken behvaiour
wispy delta
problem solved 😑
list.drawElementCallback = (Rect rect, int index, bool isActive, bool isFocused) =>
{
try
{
// 30 lines of ui code
}
catch (NullReferenceException)
{
list.serializedProperty.serializedObject.SetIsDifferentCacheDirty ();
list.serializedProperty.serializedObject.Update ();
}
Oh yeah that was one of our solutions hah
wispy delta
but now im doing it in two places lmao. i still have to do it where you did it haha
im gonna vomit

Hi everyone, as it relates to building a .net3.5 library release, is it even remotely possible to exclude a script from the exported dll even when code in the class library is dependent upon the code i want to exclude from the released library build.
The dll would require access to script that was excluded so i have that script in my Unity project and the dll will also be in the project.
craggy sedge
I'm not sure I entirely understand your question, but I think the answer there is 'no'
It's easy to exclude code from a compile via use of #defines and such, but if some of your code is referencing what you want to exclude, it won't compile
forest vortex
i think it could be done if both sets of code were compiled into separate dlls, then you could supply just one of the dlls
but i have no idea how to wrangle it into doing that
i'm not sure if namespaces create separate dlls, or asmdef files could induce it, or you might have to compile the code externally. hopefully someone else well versed in how compilation works will happen by
craggy sedge
asmdef files will create separate dlls, yeah
You can compile them externally but it'll probably be easier to use the asmdefs -then you can easily control inside of Unity which asmdefs reference which other ones
And you can catch cross-referencing issues pretty quickly
If you bring in an externally-compiled C# dll, I think Unity will always include it in your build
forest vortex
so he could put most of his code into one folder with an asmdef, and the one other piece outside that folder, and split it up that way as two DLLs
craggy sedge
Yeah
Ruchmair's question sounded more like they wanted to exclude small, specific sections of code
forest vortex
yeah but if they just put the code they want to exclude into one file, i think this could work
well one or more files
each group can be as many files as they want
craggy sedge
Yeah depending on the exact rquirements I agree that would be easier
ancient sable
two deparate dlls would work , i would just add a reference the libraries as is necessary. however since the dll would still be referenced in the other dll . the dll that uses the reference would not work in unity since unity will say that the referenced dll is not found ( while writing , i think i figured out a way to make it work)
asmdefs, I've never looked deeply into that 😬 I will do that.
craggy sedge
Yeah, you have to make sure to write the code such that the other dll could be removed without issue
In general the more you can keep code dependencies one-way only, the better
forest vortex
oh i thought he didn't want it to work unless they are given the second dll lol
but yeah if you want it to still function, i think you have to give them source code so they can compile out any missing parts using #ifdefs
or do some really ugly stuff
craggy sedge
Ohh, huh
forest vortex
like use reflection! dun dun dun
craggy sedge
I'm certain you can load dlls dynamically, but yeah that's a bit more complex
And depending on your target platform, may not actually be possible
(can't load code dynamically in iOS, for instance)
forest vortex
yeah there are ways to do it
ancient sable
its as Giometric said, i only want to exclude some code. the excluded code is already in Unity. so the solution i thought of is , compiling two dlls but the referenced one will have a single enpty code in it. then i place both in unity. Unity wont say that the referenced dll is not found.
its not the most beautiful solution but i can make use of the second dll later on
craggy sedge
When you say exclude code, do you mean exclude it from builds only?
craggy sedge
I think an #if might work depending on just how much code you're talking about
For example,
// This part will not be compiled into the build at all, but will work in-editor
#if UNITY_EDITOR
public void FunctionToExclude()
{
// Do some editor-only stuff
}
#endif
public void SomeOtherFunction()
{
// Do some stuff
#if UNITY_EDITOR
FunctionToExclude();
#endif
}
Alternatively,
// This function will always be run, but the #if UNITY_EDITOR part specifically will be excluded
public void FunctionToExclude()
{
#if UNITY_EDITOR
// Do some editor-only stuff
#endif
// Do some other stuff
}
public void SomeOtherFunction()
{
// Call this function in both editor and non-editor
FunctionToExclude();
}
UNITY_EDITOR is a define that Unity itself sets while the game is in editor-mode, and will unset when the game is put into a build. There are a variety of other ones you can use (like checking for a specific version), and you can also #define your own stuff
forest vortex
oh yeah, if you're just trying to not add stuff to builds, this is the way to go
that or put the code in the Editor folder
craggy sedge
Yeah, if you're wanting to do entire scripts that way, putting them in the Editor folder would work
(though in either case, if you happen to incorrectly reference stuff that was editor-only in some normal code, you won't find out it's busted until you try to build 😛 )
ancient sable
my idea most definitely .... didnt work 😂, i forgot that not only does a dll compiled with a reference still depend on that dll reference even when the necessary code exists in unity , but it also will ignore the code in unity that is the very same code in its referenced library.
#if wont work for this either. i will just go with full source code inclusion in unity

does anyone have a link to one of those github gists for configuring the camera speed in the editor? I used to get them from https://feedback.unity3d.com/suggestions/editor-camera-speed-must-be-configurable but that's gone now...
not up on web archive either
forest vortex
interesting, never saw one of those. i'll have to try it
river bolt
yeah I really should have one saved by now, the default editor camera speed is unbearable for working on anything less than 1m in size
makes VR development really unnecessarily difficult
forest vortex
yes I've had a lot of problems positioning in small increments. should be handy.

Hey, does anybody know, if it is possible to draw GUI elements over the Animator window like you can do it with the SceneView?
Thanks.
wispy delta
Turns out HandleUtility.GetHandleSize() is affected by the Handles.matrix and Handles.DrawingScope so if you want the size of a handle, pass the point relative to the current matrix, not relative to standard worldspace
This should be relevant to @lucid hedge as I now know the ladder handle I wrote for you calculated it's size incorrectly
lucid hedge
@whole steppe you can draw GUI elements anywhere in the Unity Editor
Ty @wispy delta for letting me know!!
waxen sandal
It's not really that easy to hook into another window to draw in there as well
grizzled minnow
@whole steppe Unfortunately, unlike the project and hierarchy window, the animation window doesn't seem to have any GUI callbacks to hook onto
whole steppe
@lucid hedge @waxen sandal @grizzled minnow Thank you for your answers! 😃
ancient sable
here is a quick tip.
If you have an editor window script whose editor window you wish to launch from a function call in a dll. you must reference the necessary assembly. e.g EditorWindow.GetWindow(Type.GetType("myNamespaceIfAny.MyEditorWindowClassName, Assembly-CSharp-Editor"));
wispy delta
I'm messing around with extending the transform inspector. There's an internal class, TransformRotationGUI that is used to draw the rotation property gui in the standard Transform editor. Is there a way to create and use an instance of the class via reflection?
forest vortex
not sure, I know this addon modifies the transform inspector
but i don't see mention of that class in it
visual stag
you can instance any class you want by using Activator.CreateInstance
so you'd get the type with something like Type.GetType("UnityEditor.TransformRotationGUI,UnityEditor")
then use the activator to create an instance
and call any methods after you've retrieved them like: type.GetMethod("RotationField", BindingFlags.Instance | BindingFlags.Public)
in some cases (like method overloading) you may need to provide an array of types to GetMethod to specify exactly which one's relevant
wispy delta
thanks @forest vortex I'm gonna try and get it to work with reflection first so I can learn more about how it works and then I'll check out the repo. If it draws a rotation field without weird quaternion to euler shenanigans I'm going to be very happy.
thanks @visual stag I didn't know about the activator class. I think I've got the gist of how it works, but Type.GetType is returning null. Any ideas? According to the cs reference, the class is in the UnityEditor namespace just like you put, so I'm not sure what it's unhappy about
here's the stripped version of my custom editor with the relevant bits
private object rotationGUI;
private MethodInfo rotationGUIOnEnable;
private MethodInfo rotationGUIRotationField;
private void OnEnable ()
{
if (rotationGUI == null)
{
var type = Type.GetType ("UnityEditor.TransformRotationGUI");
rotationGUIOnEnable = type.GetMethod ("OnEnable");
rotationGUIRotationField = type.GetMethod ("RotationField");
rotationGUI = Activator.CreateInstance (type);
}
rotationGUIOnEnable.Invoke (rotationGUI, new object[] { properties.Rotation, Content.Rotation });
}
provide it as I have specified
Type.GetType("UnityEditor.TransformRotationGUI,UnityEditor")
which includes the Assembly
wispy delta
Ah, I assumed that was a misspelling lol. I guess there's another class with the same name b/c now it is throwing AmbiguousMatchException: Ambiguous match found.
wispy delta
Gotcha, I'll use the overload with the types array 👍
I assumed it would pick the version without any arguments if you didn't specify but I guess not
visual stag
and now you can do anything with your new reflection knowledge
ignore the "internal" keyword just by simply typing 100 lines of verbose string-referenced code
wispy delta
lol yea. there's a whole new world of builtin editors to ravage
forest vortex
so what does that do, make the rotations whole numbers only?
wispy delta
eeh. making rotation gui is just really annoying. it seems simple - but there's a bunch of weird shit that kinda gets in the way of just drawing the euler angles unless you're ok with a random axis becoming -89.9999. take a look at how unity handles it if you wanna see how not cut-and-dry it is https://github.com/Unity-Technologies/UnityCsReference/blob/73f36bfe71b68d241a6802e0396dc6d6822cb520/Editor/Mono/Inspector/TransformRotationGUI.cs
forest vortex
i see. I'm guessing that tweaked inspector i linked to does it the quick and dirty way
i haven't extensively used it but it looked neat with all the added features
but if it's going to make everything 89.9999 i probably don't want it 😛
wispy delta
yea it looks like it just changes the euler angles :(
the extra features look nice tho!
forest vortex
make a hybrid 😛
wispy delta
yea I guess that's the move haha. i've been grinding hard for too long on my main project so I've been enjoying taking small breaks to do simple projects that I can finish in like a day. i think this will serve that purpose
forest vortex
if you finish it i would love a copy 😃
wispy delta
yea i'll throw it on the hub
wispy delta
Is there a preferred/clever naming convention for storing method infos or is it whatever? im not sure if its too explicit to include the name of the type of object the method is from in the variable name
wispy delta
ok cool i'll stick with on of those
verbal wyvern
What is the "Persistent View Data Dictionary" and how can this be used?
wispy delta
It's 7am and i never actually went to bed. i got kinda obsessed with adding the features in the repo @forest vortex linked while minimizing clutter to the editor.
I moved the "random rotation" and "snap to ground" buttons to the context menu which cleans it up a bit, but the part I'm most proud of is using reflection to draw an invisible float field over the "Scale" label so you can drag to change the entire scale vector.

Full disclosure: the lifetime and fading thing took 2 days 😂

Nice, I've wanted to do something like that

@wispy delta yeah the scale label trick is pretty nice. Great job 😃

question. I have an Array of Components on a gameObject and an Array of MethodInfo for C omponents[0] for example.
what is a nice way to draw out each arrays content in a dropdown. similarly to the way it appears in the UnityEvent UI in the inspector ?🤔
i was thinking of pushing each Component and MethodInfo name into a string list or array which can actually serialize and using a EditorGuiLayout.Popup to draw out each component name and meThid name but i would end up with four different arrays. i would prefer to just use two

hello, how can I add a tooltip to Editor Button?
I can add tooltip to the variables but not to the EditorGUILayout items?
When I hover to the GUILayout.Button("Add Upgrade") I want a little box appear
ok nvm I found the answer : I used GUIContent content = new GUIContent("Button", "Info Pop-up");
and put it in the GUILayout.Button(content)

any info on if we will be able to use a .net framework higher than 3.5 for managed libraries in unity ?

You can use GenericMenu and do your own dropdown logic. That way you don't have to make them serialized if you don't want
ancient sable
@grim monolith I'll give that a try, it looks very promising
also, Bunny83 (dont know his real name ), wrote a nice little SerializableMethodInfo.cs that i will be making use of later on

Hi, does anyone know if there is an event that gets fired when a material is dragged onto an object from the project window to the scene?
(or any similar event)

closest I could find is this: https://docs.unity3d.com/ScriptReference/EditorApplication-projectChanged.html
there's also a similar bool you can check: https://docs.unity3d.com/ScriptReference/EditorApplication-isUpdating.html

Don't know, if this helps, but: https://docs.unity3d.com/ScriptReference/EditorGUI.BeginChangeCheck.html
and then, of course, in an if statement: https://docs.unity3d.com/ScriptReference/EditorGUI.EndChangeCheck.html

Anyone knows how to use the built-in shaders package you can download from the Unity archive?
When I move it to my project I get a few errors about seemingly missing API
Looking at the Unity source code repository, both of those missing properties seem to be internal scoped, and given their assembly is the Editor assembly, shouldn't I be able to see them if these scripts are placed inside an editor folder?
Actually, scratch that last remark, since the assembly defined by Editor folders in your project is a separate assembly than the actual UnityEditor.dll
In that case how are the built in shaders even meant to be used?

@whole steppe change checks are for wrapping GUI controls to see whether they have been modified, it will not be helpful for capturing a drag-drop
whole steppe
Yeah, you are totally right. I've mis-read the question.... Didn't read the part where it said "scene" 😣
visual stag
(unless you have access to that control and scope of course, which in this case they don't) 😉
also ya'll can wrap links in < > to remove the pesky preview
I can help you there, give me a moment
Is the question still relevant, you deleted it....
whole steppe
Sorry, my post got deleted. it might have been considered as spam when I wanted to paste my shader :/
visual stag
Hrm, not sure why it did that, either way the answer is to use https://mvi.sh/notes/
which is an extension that adds disqus comments to the Unity docs
I have a comment on Graphics.DrawTexture that answers the question
If providing your own Material - it will not be clipped under other GUI elements.
To fix this provide a Shader with the following layout additions:
sampler2D _GUIClipTexture;
uniform float4x4 unity_GUIClipTextureMatrix;
struct v2f {
float2 clipUV : TEXCOORD1;
}
v2f vert (appdata_t v) {
float3 eyePos = UnityObjectToViewPos(v.vertex);
o.clipUV = mul(unity_GUIClipTextureMatrix, float4(eyePos.xy, 0, 1.0));
}
fixed4 frag (v2f i) : SV_Target {
col.a *= tex2D(_GUIClipTexture, i.clipUV).a;
}```you can find an implementation in builtin_shaders\DefaultResourcesExtra\Internal-GUITextureClip.shader

First off: Thank you for your quick response! :)
So you suggest, that I add the lines above to my shader?
