You really set yourself apart from other unity channels with those last few videos of yours...such unique content!

[@TheEclipsedLock]

I was following this until I got to 7:46 at which I was very confused as to why nothing was transparent. I had followed the point to make the background 0,0,0, no alpha, and I was confused as to what was going on. The secret? Also change the "Clear Flags" option on the Main Camera from "Skybox" to "Solid Color". Build it and bam, the transparency is there :D

[@neodubzero8448]

There's always a hero in the comment section!! I figured it had something to do with the background.

in unity URP, you need to disable the HDR in the (Universal Render Pipeline Asset) to work properly

[@naeustudio]

thx bro

About 4 years ago, I ended up using WPF to achieve this for a game counter / healing tracker. Thank you so much for sharing this, I can make all kinds of cool stuff with the ability to make overlays!

[@louxie6367]

Ok quick tip for anyone struggeling to make it work (if you are writing the code manually): Make sure the function names (of the dll functions) are the same!! A spelling mistake will prevent it from being transparent. That's all. And thanks for the great tutorial! :D

[@CodeMonkeyUnity]

Yup when working with external functions they need to have the exact name

[@ericmenaut]

Thanks, I had a spelling mistake in a function and it was not working. Now all is perfect!

[@kimen1]

You’ve just created the Virtua Girl that many many years ago always brighten my desktop.

[@ThainaYu]

Updated: You don't need to use built in graphic. You can also use URP but it seem you need to remove some effect that would cause the background pixel to not be 0. Such as volumetric light in the scene that would make the BG lighten a little bit

Do you have any more knowledge of what to turn off? as i would love to use URP with the transparent window.

[@IgorAherne]

1 year later, for URP transparency, you have to untick "Post-Processing" (so it's not enabled) in your scriptable object "Universal Render Pipeline Asset_Renderer". Maybe there is a better way.

[@samuelbeauquin]

Great tutorial ! - Transparency work in URP in 2021.3 but you need to disable HDR and Post Processing.... - If you encounter an issue where transparent materials make what you have behind (e.g some opaque geometry) transparent as well, changing the blending mode from Alpha to Premultiply on these materials solves the problem.

I'm having an issue with the code. When I mouse over a button, it correctly changes the color to the highlight color. However, I can't actually click it. It just clicks through the button. Any ideas as to what I missed or did wrong? I checked and double checked that my code and build settings were the same, so I don't know what could be causing my issue. Edit: Finally found the fix. Because I was using UI elements, I needed "SetClickthrough(!CodeMonkey.Utils.UtilsClass.IsPointerOverUI());" in the update function.

Get Active Window just returns the hwnd for whatever window is active, not necessarily *your* window. I would recommend using a different method to get your window handle.

[@joshleap]

I was just thinking the same thing. I wonder if there's a way through the unity API to grab unity's window handle. EDIT: looks like System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle did it for me. Got this working in an hdrp project infact. Just need to be careful about your post processes you select.

[@protobilly]

@codemonkey- Does this not work with Unity UI/Canvas? I noticed you use your button_sprite plus colliders instead of the built in system.

[@protobilly]

nm- if you put "SetClickthrough(!CodeMonkey.Utils.UtilsClass.IsPointerOverUI());" in the update of the Transparent Window it'll include Unity UI, instead of only sprite collision.

[@Fluxxn]

thanks, works perfect now!

[@AriAmphibian]

I was able to get the script working decently, but I ended up running into the issue of using the Utility in the script. I was wondering if this was the only way of doing the collider interaction side of it or if there was any other way I might be able to do it. Help would be appreciated

[@CodeMonkeyUnity]

What issue? The raycast doesn't hit anything? Make sure you're not mixing 2D and 3D colliders/physics

[@AriAmphibian]

@@CodeMonkeyUnity the issue is mostly setting up a system that makes the window only be selected whenever an object has a collider rather than relying on pixels. I’m wanting to make some objects intractable while others would be able to exist without getting in the way.

[@walterwhite42068]

Thank you so much! I wanted to do this but couldn't find a solution for years now. Will shaders on UI images work with this? Edit: In detail, I want to have a Gaussian blur effect on UI Image that will blur everything in desktop (aka the background). Is it possible to do that? I just tried and it doesn't work sadly :( Please provide a workaround

[@CodeMonkeyUnity]

This makes the background transparent, it doesn't copy it. You need to figure out some way of capturing the desktop rather than just making it transparent, I'm sure it's possible but no idea how.

[@theDarkerSan]

I used this effect in UI before. in shader graph theres a way to grab the background and aply to the shader to make it look "invisible" I think it would work in this case too.

[@walterwhite42068]

I have made a bg capturer before which blurs it on awake and sets to correct images. I'll try it here and let you know.

[@walterwhite42068]

@@CodeMonkeyUnity Sadly shaders do not work....

[@3lH4ck3rC0mf0r7]

I've researched this topic before. Unity doesn't (and can't) run its graphics instructions directly on top of its window. Unity renders the scene into a separate buffer (the BitBlt buffer), which then DWM copies the pixels to wherever the Unity window is. And when DWM copies the graphics buffers around and renders the actual window, it uses its own shaders that are essentially out of your reach. With some extra DWMAPI instructions it is possible to enable DWM's own blur and DirectComposition shaders, but not much more than that, you can't apply custom Unity shaders and post-processing effects directly on window composition. Now, since then, extra window masking flags have been added for Windows 10 allowing to record the desktop, but excluding certain windows from the rendering entirely. Such windows become completely invisible to all forms of screenshots and desktop recording (except from hardware capture cards, of course). Then you could go with a faux-transparent window that's actually opaque, but takes screenshots of the desktop while excluding itself from them, to add to those screenshots completely within Unity, where all shaders are fair game.

[@EclecticDev-vv8nk]

So many interesting things in this video I learned that would have taken me forever to figure out myself. Thank you so much.

Update!

Superb video, it definitely sparks a lot of neat ideas. Question though - I've been trying to get this to work with a virtual keyboard to send macros for games. Is there a way to have the window always remain out of focus but still allow the clickthrough to send a simulated keystroke ? I have tested the virtual keyboard to work fine (just sending a keystroke on update to a notepad), but when I try to use it via unity button, the window takes focus so the keystroke doesn't target the previous window as I would have hoped. I looked on pinvoke and saw the method for GetActiveWindow thinking I could just store whatever hWnd was active and then use the SetActiveWindow to go back there, send the virtual keystroke, but no luck unfortunately. Would love to hear any thoughts you might have on keeping the window always on top, but always out of focus ?

[@CodeMonkeyUnity]

Hmm maybe you can make the Unity window clickthrough and instead of using a regular button just add some code testing for Input.GetMouseButtonDown(0) and doing a Raycast yourself to see if the mouse clicked on a button. But not sure if that works, not sure if Input.GetMouseButtonDown(0) still triggers if the window is clickthrough

[@christopherhodge]

@@CodeMonkeyUnity I tried doing that first but it seemed as though each click would still focus the window. I eventually found this which helped out, however, it hides the icon on the taskbar, which is ok I suppose. const int WS_EX_NOACTIVATE = 0x08000000; SetWindowLong(hWnd, GWL_EXSTYLE, WS_EX_LAYERED | WS_EX_NOACTIVATE);

@@CodeMonkeyUnity So I finally made it work. Quickly though, any tips on making it work on multiple displays? Looks like it doesn't at all work with multiple displays.

[@epicei]

Did it. It works. Using it on two screens was a little bit funky, but it works great. Finally!

Can you tell me how to make collision with a desktop tab

[@specstrem]

How do i make it so that its behind the taskbar because i use the collapsed taskbar and i cant get it to show up because the game is in the way?

[@Mirza-oz8ff]

can i apply shader or post processing effects to background based on certain action? (i want to know shader effects will apply to background or not) example: turn screen colors to black & white, or apply bloom-glare to colors, or blur screen

[@CodeMonkeyUnity]

By background do you mean the Windows background? If so no, at least not with this method, since there is no background, it's transparent.

[@Mirza-oz8ff]

@@CodeMonkeyUnity my mean by background, was about desktop background or if the user is working with a tool/program, the shader apply on it example: turn desktop screen blurry

[@prodragon6]

@Code Monkey hey I'm just looking for advice on your transparency code, I made it work but it doesn't play nice with TMP and causes resizing issues for internal windows. any idea why that is? I have it passing everything through problem free until it tries to make new text and parent to a thing within my window

[@Matt-fm1wo]

Is it possible to make a 3D object (like the cube) clickable/draggable for example? Or does interaction only work on sprites? Is there some special method for interacting with objects perhaps?

[@Matt-fm1wo]

I figured it out. I think the main thing was having the keyboard and mouse work when it's not in focus (I used the rewired asset to do so, but it's possible with other windows API)

[@RoadHater]

@@Matt-fm1wo Could you provide specifically how this was accomplished?

[@themattempire42]

@@RoadHater not sure as this was a LONG time ago...but I think based on my comment you have to make your app always in focus, so if you click on other things the app is still 'on top' kind of thing.

Hey CM, I am having an issue with the collider check. I want to use a RigidBody2D with the script but the collider check does not work while the rigidbody is dynamic. Do you know a way around this?

How do I create a Transparent overlay on top of an UI Image or certain passive UI Elements, to allow the user to make in-game annotations ?

[@KasperSOlesen]

I was trying this out, but just could not get it to work. I have tried several things... I figured maybe it was because I was using a newer version of Unity so I downgraded. I tried double checking all the settings, ensuring the camera settings were right, but I even installed the package from the website and used the scene from that. Only thing I can think of that it might be, is that Unity logo at the startup. Because I get whatever graphics I have in the scene, but the background is completely black. Solid black instead of transparent. I thought maybe it was one of my other running apps that caused the problem, but I closed that and still no difference.

[@CodeMonkeyUnity]

I haven't tried it in new versions but the one I used here still works nowadays. Importantly it only works on the built-in render pipeline so make sure you're not using URP in the project. Also don't add post processing or anything that uses depth textures or something like that, those can cause problems.

[@KasperSOlesen]

@@CodeMonkeyUnity might be something specific on my computer, I have tried several versions of Unity now, several different ways of doing the code, I can get it to be on top and be click through, but I cannot get the transparency working. I didn't other transparency Unity examples and I could not get any of those working either. I have made sure not to use URP, disabled HDR and any other special features, went over the project settings several times, tried making changes to the boot logo since I cannot disable it. But i always have a solid black background.

[@luisrosado7223]

Im subscribed but i would really appreciate it if you provided Code outside of the Unity IDE for personal analysis. I dont use the Unity Platform but i am trying to create certain effects for other languages.

[@CodeMonkeyUnity]

The .unitypackage includes all the source code, so if you're not interested in Unity you can import it onto an empty project and then just grab the source code and copy paste it to your non-Unity project

[@shogoun94]

Hello, i appreciate your work !! I just wanna ask does this transparent work on build ??

[@CodeMonkeyUnity]

Yes, I make the build at 7:30

[@nursyahidatulasyiqin8724]

Is it possible to have the screen not in fullscreen but set to 3840x1080? How?

do you know if this is possible to do in vr? like i want my transparent window to run on top of other games

[@drtringuyenzmc]

Hey, thank you so much to your tutorial, I just wanna quick asking if this work on MAC build too?

[@CodeMonkeyUnity]

This is using the Win32 API directly so no, maybe the Mac API has similar functions but no idea.

[@drtringuyenzmc]

@@CodeMonkeyUnity thank you so much, this is exactly what I'm afraid. There are some apis that only work with certain os. Last time I have the same problem with itext when run on Mac. Thank you so much for instant reply. If you can show me some keyword more to search for this problem it will be supper helpful. I searched with all keywords related to your subject but for Mac and still find no hope yet. Thanks so much

When doing menu animations, do you use the animator or a tweening plugin?

[@orun1]

You don't need a plugin for tweeting: kzbin.info/www/bejne/gp2Wqqigo556jLM Here's a tutorial. Btw if the link doesn't work just search you're animating UI wrong, it's a video from Game Dev Guide.

[@In-N-Out333]

@@orun1 That video only shows you how to do it with a plugin. Did you even watch it?

[@CodeMonkeyUnity]

Normally just code based tweening but I never go too crazy with my menus.

[@DevVand]

OMG THE DOWNLOAD ARCHIVES ARE A TOTAL MESS

[@GiantCloudGames]

Could I blur the screen somehow? like a gaussian blur or frosted glass.

[@CodeMonkeyUnity]

Don't think that's possible, through this method Unity has no context on what is behind it

[@hedyxalil9736]

Can you make video about when in game chapter 1 end after that how a player and camera go to chapter 2 another location and map how this can be done alike call of duty somthing alike that ? thx

[@CodeMonkeyUnity]

Usually you just load a completely different scene. If you try to smoothly move the camera you're going to have to deal with dynamically loading and unloading or you end up with memory constraints.

[@eschewary367]

Got it working, thank you so much! To anyone who's done this and gone further, I want a transparent window, which I have, but I can't move it, it's stuck where it's placed when built. Where can I go for info on resizable, movable windows?

[@CodeMonkeyUnity]

The way I do it is use this in full screen then make a UI window just like any game window which can be dragged. It's what I used to make a Poll window in my Livestream overlay unitycodemonkey.com/video.php?v=Mb2oua3FjZg

[@eschewary367]

@@CodeMonkeyUnity Thank you for the reply. That solution won't work for me because I need the actual Unity app Windows API window to be resizable/draggable. I think I need to switch WS_POPUP with WS_OVERLAPPEDWINDOW, now trying to disentangle that from StephanM's code haha

Thank you for this great tutorial, but I have a little isue, the application disappear (I need to click on it in the windows bar to make it visible again) when I click out of an UI element the SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, 0); method seems to doesn't work. I use the Unity 2020.3.18f1 on windows 10 19042.1237 build. Do you have the same isue with my configuration or did i make a mistake somewhere ? Regards, Pascal

[@prz1968]

Ok I find the solution, in Standalone player option, the visible in background must be checked

[@overlord--]

Can you look into getting this to work with Unity 2021.3 HDRP with the ability to have post-processing? This would allow some cool stuff! Thank you!
