IAP Button goes missing...

I am using Unity 2017.2. I am using Unity's Codeless IAP Buttons. I can import the IAP Buttons and add them just fine.

However, if I leave the Scene and come back, the IAP Button component is replace with the empty compoennt of "Nothing Selected". If I reimport Unity IAP without leaving the Scene, the IAP Buttons come back. But as soon as I leave the scene and return, they are gone again.

When clicking on the script, it says "No MonoBehaviour scripts in the file, or their names do not match the file name." in the inspector. But IAPButton is a MonoBehaviour, and there are no typos in the script name nor class name.

I have tried publishing with the brokenness, but the buttons do not appear to do anything.

What is going on here, and how can I fix it?

 

Can you elaborate regarding "reimport Unity IAP without leaving the scene"? Do you mean leave the scene when in the Editor, or when playing the game.

 

Same here.
I have grid layout with 5 products and iap buttons inside each. When i start the game in editor, all iap button scripts just dissapear, except the first button.

 

Hello,

I have a bug quite similar with 2017.2, I cannot find the origin.
It works well in unity for me , but when I build using cloud build, all IAPButton scripts goes missing.

When I say missing , I mean the MonoBehaviour link in my objects seems lost , I get errors in log in running :

But no compilation error.
Also,I made a script to test if the class was compiled using reflection, and the answer is yes :

Last thing, I have noticed that the script file IAPButton.cs had the message

Very strangely, i just edited the file and CTRL-Z, and the message went away.

Could that be a bug with unity not recognizing well the MonoBehaviour in the file for some strange reason ?

 

Hey just a little follow up . I have duplicated the IAPButton class to make my own, and got the exact same problem.

A fix that seems to work for me is to remove the #if UNITY_PURCHASING directive. Now the script works fine, event in cloud build.

So just to be clear, it seems that
- The UNITY_PURCHASING compilation constant is defined
- The class is fully compiled (i have checked that)
- When built the class is missing from serialized objects

@ap-unity I dont have the time to make a small project to reproduce and I am not even sure it will reproduce the bug as it seems random. But I highly suspect that something is randomly wrong with the #if UNITY_PURCHASING and the ability of unity to recognize the MonoBehaviour inside it, even when defined.

 

@ap-unity @JefffDUnity3D

Sorry for late reply. I was expecting an email if someone responds to threat, but never got one. I thought it went ignored.

@thibouf 's Answer seems like it could work. I am still doing some testing, but the problem is probably within there. I will let you know if it persists, even with #if UNITY_PURCHASING commented out.

 

Editing the files should not be necessary. I just created a simple project using Unity 2017.3.0b9 and IAP 1.14.1 and dropped 3 IAP Buttons into the scene. They remain visible when I run the project. If possible, please provide exact steps so that we can reproduce the issue here.

 

I am facing the same issue. IAP Button goes missing and is described to have no MonoBehaviour connected. Using the windows menu allows you to add a new one. Loading from the file tho causes a potential issue where the button may disappear again.

 

Please test with 2017.1 and 2017.3 and see if the issue persists. There may be an issue with the UNITY_PURCHASING directive on 2017.2.

 

I faced with similar problem, but in my situation that this bug is appear after Unity's crash (it is crashing sometimes). I'm using Unity 2017.2 on MacOS. Also, under the Player Settings -> Scripting Define Symbols there is no UNITY_PURCHASING directive, but UNITY_INAPPS is there. I added UNITY_PURCHASING manually, but seems that didn't help.

 

@GroznyBear Please test with 2017.1 or 2017.3. There may be an issue with the UNITY_PURCHASING directive on 2017.2.

 

Face this problem in 2017.2. Reinstall unity 2017.1, delete library folder and re-open the game is fixed for me

 

In 2017.3.0f3 I see issue similar to what @stanison says about "IAP Button goes missing and is described to have no MonoBehaviour connected." This occurred when upgrading existing projects from 5.6.3.

The specific, very weird error, is the IAPButton class is broken with non-compile error. BUT, everything has compiled fine with no Console errors at all. The game runs, with only warnings about the uncompiled script. See the screenshot if this seems crazy.

I've tried: deleting Library folder; deleting and re-importing the latest Unity Purchasing; looking at the IAPButton in MonoDevelop (it compiles fine, see screenshot). Also a brand-new project importing the Unity Purchasing does not fail.

Currently: my setup is one master repo, with 2 nearly identical branches. Working in one of the branches, I fixed the issue (somehow, unclear steps), but merging back to the master does not resolve the problem.

NOTE: My repo has a master and 2 nearly identical branches; working in one of the branches I managed to solve this but I don't know why it suddenly started working. Still looking...

 

This was real weird, but to solve it I copied the entire project MANUALLY from the branch and dropped it over the master. There was not a single change in git, BUT it magically started working. ??? Guess it may have been a bad asset somewhere, maybe in the cache server or somewhere outside the Assets folder which is not part of the git commits. Good luck to anyone who sees this!

EDIT: Seems to have broken down again!

 

Hello,

I have not been able to correct this issue. Every time I build the project, it breaks and shows the empty component issue.

 

Creating a brand-new .cs file and pasting the contents from the IAPButton.cs script fixed the compile problem for me. The script also had a weird "gem icon" that disappeared. I suspect some type of corruption in the file itself. In git it showed modified but with NO changes to the script; only changes to the metafile.

 

@JeffDUnity3D
I am still having this issue with 2017.0.3
Do you have any more information about this problem ?

 

Sorry, I don't have further information. You mentioned that commenting out #if UNITY_PURCHASING directive was working for you (which shouldn't be necessary). If you continue to have issues, please provide a simple project that reproduces the problem. You can submit the project in a support ticket which you can create at https://analytics.cloud.unity3d.com/support

 

Every time I delete my Library, the IAPButton stops compiling. This occurs in multiple projects. Each time it can be restored by editing and recompiling the script.

Note that this is a specific, bizarre problem, since everything DOES compile, and the project runs in Editor with missing behavior errors. Yet it states that IAPButton has not compiled. But then, by editing IAPButton.cs in any way, it recompiles and works as expected. See screenshots in my post above.

PS. The UNITY_PURCHASING directive doesn't seem to be involved in my case.

 

@kwikdev Please provide steps so that I can reproduce on a new project.

 

@JeffDUnity3D I will try but it is quite hard to make a reproducible project as the issue seems a bit random .. For example, in my own project it was working fine, then I don't understand why it started to not work anymore at one point ...

And I confirm that removing UNITY_PURCHASING fixed the problem for me...

 

Ah also, i had the problem only in builds made with Unity Cloud Builds, on my local machine, it was fine ... (so it's even harder to create a sample reproducible project ...)

 

I hate to not provide insightful information regarding this problem but it is happening to me.

I am using 2017.2.0f3 and I don't use the directive in my code.

This is how I think this issue originated.

I had my 2017.2 project with codeless IAP buttons working as expected, I even built for iOS to test these buttons and they worked fine. I also let Unity run for over a week while randomly using my Mac laptop for other stuff, though Unity remained open with this project loaded.

Then I decided it was time to set a VCS to sync between my Mac and pc.

- Copied my project to another folder to be tracked with bitbucket on my pc.
- I uploaded my project to bitbucket using SourceTree
- IAP buttons show 'nothing selected' in their respective component section in the inspector window.
- To solve this I created a placeholder IAP codeless button, copy and paste the IAP Button component of that placeholder IAP codeless button into my real IAP buttons and set things up.
- problem occurs as soon as I close Unity and open same project back again: 'nothing selected'. I also get console warnings that arise from this issue on my Mac and pc.

These are:
- The referenced script on this Behaviour (Game Object 'IAP restore') is missing!
- The referenced script on this Behaviour (Game Object 'IAP purchase') is missing!

Foolishly deleted the original project so the BitBucket project is all I have though this is the only issue I have.

UPDATE:
After opening the project again I noticed the placeholder IAP codeless button is now also showing in its component section in the inspector 'nothing selected'. Note that the Image and Button component do show correctly.

Unity please help!

 

My .gitignore file looks like this:

.DS_Store
Library
Temp
*.csproj
*.pidb
*.unityproj
*.sln
*.userprefs

 

@JeffDUnity3D Can you please take a look at my posts?
Thanks

 

@gegagome Sorry I'm not sufficiently familiar with your source control system to spot any issues. Someone said earlier that removing the Library folder caused issues, and I noticed it is in your gitignore. Also, please try with 2017.3 as 2017.2 had some issues with the UNITY_PURCHASING directive as mentioned in earlier posts.

 

I have confirmed that deleting the Library folder (or using gitignore or similar for the Library folder) is not good for Codeless IAP and causes the scripts not to load. I have let the IAP team know.

 

@JeffDUnity3D So it looks like my issue was clearly moving the project between folders to get it ready for BitBucket.

I built and tested my IAP buttons in late November and early December using 2017.2

I updated my project to 2013.3.0f3 and the buttons are still gone, but at least they are saved after I quit Unity.

So my educated guess is: 'nothing selected' began happening after pasting (I think I did this but I am not sure if I moved the actual folder to a different location, shoot my memory) the files of my project to another folder.

 

For now, you may have to start a new project and reimport your assets (if removing the UNITY_PURCHASING directive in the script file doesn't work for you). And don't set the gitignore flag for the Library folder.

 

@JeffDUnity3D @ap-unity
It was the placeholder IAP button (from where I got the IAP Button component to paste it to the 'nothing selected' IAP buttons) that I forgot to delete.

I removed my original post as to avoid confusions.

Hopefully my IAP codeless buttons will stick around.

Thanks

 

@ap-unity Thanks for providing these solutions. The Library definitely seemed to be involved in the problems I was seeing, your repro steps make sense. Notably, I also got the script to re-compile simply by editing and saving the IAPButton.cs file.

 

Removing and reimporting the Unity IAP plugin fixed the issue for me locally. This is a really annoying issue, though.

Is there any estimate when this bug will be fixed?

 

@tarmo-jussila We are working on it at high priority, you should see improvements in an upcoming version. IAP plugin development needs to coordinate with ongoing Editor releases, so we can't always release separately.

 

Is there an issue tracker for this issue? Which upcoming version is the fix coming in?

 

We are still investigating, no ETA yet. I don't believe there is an external facing issue, I will check with engineering and get an update, and will reply here when I have additional information to share.

 

@JeffDUnity - we just updated to the newest IAP in Unity 2017.3.1f1. Is the fix expected to be in place for this setup?

I ask because the non-compiled IAPButton still recurs every time we delete the Library folder.

We're hoping to find a fix or workaround that can be applied on Unity Cloud Build too. Thanks!

 

I don't believe we have addressed the issue yet of removing the Library folder, no ETA yet at this time. You've tried the work around of editing and saving the file?

 

Thanks for the news.

Yes, the edit / save works to re-compile locally. Unfortunately, on Unity Cloud Build it breaks since the Library is re-created there. Do you have a workaround method for UCB? Checking the entire Library in comes to mind; but that's kind of extreme. If it's fixed in 2018 we'd jump there to fix this.

 

Good news, the fix for this issue is now in the most recent patch releases. I tested on 2017.3.1p2 and it is working as expected after deleting the Library folder. https://unity3d.com/unity/qa/patch-releases

 

Excellent! In 2017.3.1p2, it does appear fixed. Thanks, Jeff!

 

Somehow, some way this bug has resurfaced in Unity 2017.3.1p4

It seems to have the same repro steps. It's still a bizarre error where IAPButton.cs does not compile, but otherwise everything in Unity is fine.

Jeff, am I seeing things, or has the fix slipped back out?

 

@kwikdev Can you provide specific steps to reproduce in your case? Did you delete the Library folder for example? Also, what version of IAP are you using (check the top of the Changelog file in Assets/Plugins/UnityPurchasing)

 

I believe the steps outlined by ap-unity above are still accurate:

1. Create new project, import IAP and create a Codeless IAP button
2. Close project and delete Library folder
3. Open project and the IAPButton script will be missing

As we use Unity Cloud Build exclusively, the Library is cleared and this issue always occurs.

This is the most recent version in the Changelog:
## [1.18.0] - 2018-03-27

We're using the latest Unity available, which seems to be 2017.3.1p4, but would upgrade to any version where this is fixed. Is 2017.4 available to developers yet?

 

@kwikdev Are you able to test with a local build? 2017.4 is available here https://unity3d.com/unity/qa/lts-releases

 

Thank you, I had never found the LTS builds. Yes, this is fixed in 2017.4.1f1

 

I'm also running 2017.4.1f1, and for me it disappeared again. At least one of them is.
Initially one button (of the 4 I have) just kept losing track of the iAP product ID, but now the script is lost again on this button.

Edit: On build or play it goes missing on 3 of the 4 buttons.

There is also no way to add the script manually on an existing game object with 'Add Component'. It doesn't exist there, you have to use the top-menu to create it. Not sure if that's related, but it seems strange.

I guess not using the IAP button is the best strategy for now.

 

@DavidSmit If you could provide steps for us to reproduce on a new/empty project, it would be appreciated. This issue should be resolved for the general case, you might have something else going on.
