HOT RELOAD - Edit Code Without Compiling!

Hey there. I don't get this error when I open a project with Hot Reload installed.

This omnisharp log seems to be relevant. If you're missing it, you might want to look for related errors in the log output:

[info]: OmniSharp.MSBuild.ProjectManager

        Update project: SingularityGroup.HotReload.Editor

But if the error doesn't cause issues for you, you might as well ignore it.

 

For now, I ignore it, but I think I should let you know this:

[warn]: OmniSharp.MSBuild.ProjectLoader

This should have been default 10 years ago.
AKA: Run without full recompile, make live changes.. etc

 

My coworker and I have found Hot Reload to be less reliable lately (on 2022.3.4).

He modified a debug log, Hot Reload said patched, but no change in logging.
I have a ton of issues with Rider and Unity generally of late, with features like debugging just not working well (I want to doubt that this even has anything to do with Hot Reload), but then when I hot reload anything, debugging is virtually guaranteed to glitch and error out.

 

Hey, if the change was made inside coroutine or async method, changes are only reflected when that coroutine/task is recreated. Perhaps this is what you were experiencing? We can add a warning when this happens to avoid confusion.

If it was some other change, feel free to DM me with more details on what change was made and in which context.

We haven't made any changes to the debugger recently, so I assume something in your project changed. Feel free to let me know the details of the issues you're having with it though so I can provide some assistance.

 

A warning for any edge case would be greatly appreciated, I don't recall if the log was in a coroutine, but we don't use them often.

I'm trying my best to nail down where my instability issues are coming from, it's mostly Unity crashing and Rider just not debugging properly. If I encounter anything specific to Hot Reload, I'll relay it immediately.

 

This looks good, though if you see minutes of time saved on each code change you must have a very slow PC!

However the pricing is still very high for business users - but it looks like most might fit the indie licensing, was the 10+ employee a recent addition? Because it is a bit confused now as Business has a tick by Pro/Enterprise while Indie does not

 

Hey there. We believe the pricing for a business plan is fair, considering the amount of time saved on large projects. We are open to considering individual approaches to companies who don't think that is the case (e.g. via a call).

Not all Pro/Enterprise users are eligible to use the Hot Reload Indie license, and that is why we indicate full support for this type of license in the Business plan. Information at the top of each plan is there to help you understand when you should purchase either Business or an Indie license.

 

I think it will get there, but it does appear limited until the following are covered because I would be constantly doing one of these:

• Adding or editing fields in classes
• Adding new classes or structs
• Adding C# files

 

From what users have reported so far (including companies on the Business plan), it's clear that existing Hot Reload features provide huge time-saving potential. It can save hours allowing you to fix bugs in play mode or with on-device build etc.

The features you've listed are on the roadmap, and your early involvement will help with development. Of course, you can choose to delay and wait for these features to be available.

You can try Hot Reload for free with a 30-day trial: https://hotreload.net/download and see for yourself if it's a good investment.

 

I second the "Adding new fields" feature, would be a fantastic addition. Also changing constants (const floats, ints etc) values, I'm surprised that wasn't supported.

 

We are working on adding new fields feature at the moment. ETA is 2 weeks from now. I will take into consideration your need for support of patching constant values, but can't tell where it will be on the list of prioritized features.

 

Hey everyone!

We just released version 1.12.4.

Fixes:

• Made Hot Reload correctly identify changing field types and removing fields as unsupported changes
• Fixed an issue with unity event functions not executing when entering Play Mode
• Made Auto Recompile Unsupported Changes option more reliable
• Assembly definition files and native plugins (e.g. dll files) can automatically trigger Unity Recompile

 

Seeing this exception when adding an override of a virtual method. Not sure if that's meant to be supported or not, but figured I'd share.

 

Thanks for sharing this. Adding override methods is not supported yet but to my knowledge it should give a different error. We will investigate.

 

hi,I have many error in vscode
version 1.12.4

I

 

Thanks for reporting this. The fix will be included in the next version (coming out in a few days).

 

Hey everyone!

We just released version 1.12.5.

Fixes:

• Fixed being able to dismiss the "Rate App" prompt
• Fixed the "Show on Startup" option reverting to "Always"
• Ensure original Auto Refresh preference is restored when Hot Reload is uninstalled
• Fixed harmless errors in VS Code

 

Latest version (1.12.5) should have the fix for it. You might need to regenerate your project files like in the screenshot below:

 

I'm getting a lot of errors when creating a build through BuildPipeline.BuildPlayer in our project (we have a custom build tool). I've unticked "Include Hot Reload in player builds" yet it still seems to be trying to build with Hot Reload. Building through the standard Build Settings window works fine though.
Also, when shutting down Unity with Hot Reload running locks up Unity with the following progressbar looping indefinitely. If I first stop Hot Reload and then shut down Unity it closes as it should.

 

Hey Andreas,

The first issue you've mentioned is a known one and we're looking into it.
The workaround is to remove Hot Reload package from the build machine before starting Unity.

For the second issue: what is the Unity version that you're using?
And did it start happening with a recent update or was this way before?

 

We're running Unity 2021.2.7f1. I believe it started happening 1-3 months ago (I've been too lazy to report it). Hard to say exactly when as I usually leave Unity on and the first times I just chalked it up to Unity being Unity.

 

Andreas,

You can resolve this issue by adding a line in EditorCodePatcher.cs:101 on the latest Hot Reload version:



We will include this fix in the next release. Thanks for reporting this!

 

There seems to be a bug where it doesn't detect method name changes as an unsupported change. So for example, changing Update to FixedUpdate doesn't hot reload and doesn't recompile automatically, forcing me to compile manually, even though I have "Recompile immediately" enabled.

There are no errors in log, and it does say "Hot reloading FixedUpdate" as if it worked, but any changes I make within the method until I manually recompile won't hot reload.

It would be nice to have a button for manually recompiling in Hot Reload window for if something goes wrong with it. Currently, as I'm not sure what the most convenient way to recompile is, I add a script that I then delete, so I end up recompiling twice each time I change a method name.

 

Hey there, thanks for reporting this issue. We will investigate it and deploy a fix in one of upcoming versions.

We are also working on UI improvements, which will include a recompile button.

You can use default Unity shortcut for recompiling (Ctrl+R), which is the most convenient way to do this right now.

 

Hi,

Thanks for the great tool I found it very useful! However, I've noticed that it doesn't track script changes inside symlinked directories. Would it be possible to handle this issue or provide guidance on making it work with symlinks?

I'm using Mac 12.6 and Unity LTS 2021.3.8f1

 

Dear Hot Reload,

Today i had bought hot reload for unity on hotreload.net, but i cannot used because that package need to registering into licensespring.com. I'm believe i didn't has any account on licensespring.
Also while check on my unity account store, that package didn't showed on my asset.
I need your feedback soon.
Thank you a lot

regards,

Antony A

 

Unity 2021.3.29f1
Hot Reload 1.12.5
UniTask 2.3.1
Rider IDE 2023.2.1

Hi, I've experienced some issues with UniTask library. I added line 17 and got a TypeLoadException error when entering Play mode. Turning off Hot Reload doesn't help, restarting Unity with Hot Reload turned off also doesn't help initially. But if I remove the line, then fully recompile and add the line again, and fully recompile, the issue is solved with identical code. So I'm inclined to think that it's Hot Reload related.

Code (CSharp):

1. using System.Collections.Generic;
2. using Cysharp.Threading.Tasks;
3.  
4. namespace Obscured
5. {
6.     public class ScenarioEngine
7.     {
8.         private List<CommandBase> _commands;
9.  
10.         public ScenarioEngine(List<CommandBase> commands)
11.         {
12.             _commands = commands;
13.         }
14.  
15.         public async UniTask RunScenario()
16.         {
17.             await UniTask.NextFrame();
18.  
19.             foreach (CommandBase command in _commands)
20.             {
21.                 await command.Execute();
22.             }
23.         }
24.     }
25. }

This is the error and it pops up whenever I add the line and try to enter Play mode with Hot Reload turned on.

Code (CSharp):

1. TypeLoadException: Could not resolve type with token 0100000b from typeref (expected class 'CommandBase' in assembly '')
2. Cysharp.Threading.Tasks.CompilerServices.AsyncUniTaskMethodBuilder.Start[TStateMachine] (TStateMachine& stateMachine) (at Library/PackageCache/com.cysharp.unitask@f48cb4b03e/Runtime/CompilerServices/AsyncUniTaskMethodBuilder.cs:111)
3. ...

 

Hey Antony, we've responded to your email, let us know if you need further help.

 

Hi. Unfortunately, we haven't found a solution to this problem yet.
Feel free to reach out via Discord or email to discuss your use-case, there is a chance we might find a solution for you.

 

Hey there, it seems that Hot Reload has an issue with field closure in async context (not exclusive to UniTask lib).
Changing `_commands` to `IList<CommandBase>` seems to work around the problem.
We will look into making a proper fix for this issue. Thanks for reporting it!

 

Hi there @PencilBow,

running into a weird issue. I'm not a 100% sure its related to Hot Reload but I thought I'd ask you.

I'm making development Mono builds and the code doesn't seem to update/recompile in the build.

I'm 100% sure that I'm building the right scene, editing the right script, and running the correct executable.

The code I'm changing is basically an OnGUI function on a MonoBehavior, and I'm just adding more GUILayout.Button calls and they're not showing up in the newer builds, it shows a version of the code that is a few builds old.

NOTES:
- If I uncheck Development build, the code updates properly, subsequent changes are reflected in rebuilds
- If I build IL2CPP (Development or Release), the code updates properly, subsequent changes are reflected in rebuilds

Things I tried:
- I tried turning off the option for HR to attach to builds, it didn't help
- I tried turning off HR completely, it didn't help
- I tried turning off/on HR, it didn't help
- I tried deleting temp Assembly-CSharp.dll files from HR temp folders, it didn't help
- I tried enabling/disabling Play Mode Domain reloading options, it didn't help
- I tried "Clean Build", it didn't help
- Restarted Unity, regenerated project solution, it didn't help
- Restarted Computer, it didn't help

Something is getting cached somewhere when making Mono Development builds and I can't figure out what or where...

Any ideas what's going on? Or if there something you could think of I could try to investigate further?

 

Hey, have you tried removing Hot Reload from the project (maybe that's what you meant by "turning off HR completely")?

To investigate further, you could create a new project and try to add changes that you suspect are related to the issue.
Once you reproduce it, remove changes one by one and test after removing each one until the issue goes away. That will tell you which change was the culprit.

If you have a project with a reproduce, you could send it to us, and we will look into what is causing the issue.

 

By that I meant hitting the "Stop" button on HR main window. I haven't tried completely removing HR from the project, I thought I could find it in the Package Window and remove it that way but I couldn't, I guess I just have to delete the folders.

 

Strange. Hot Reload usually shows in the Package Manager.
Let me know what happens when you remove the package completely.

 

Hi! I would like to know is there any news about that?

 

Hey. We had to put field support on hold in favor of other priority fixes. We will resume work on fields in October. Sorry for the delay.

 

No problem at all, hope you guys doing well!

 

Hello! I don’t know anything about how unity and IDE work together and compile behind the scenes, but I am really tired of the longer and longer compilation times, which are becoming more and more obvious in versions after 2021...

I am considering buying hotreload. I am currently using 2022.3.6f1. This version should be considered quite new. Does hotreload support such a new version? What I mean is... How stable is hotreload for the new version of the unity editor? If hotreload is still in the process of patrolling and ironing out bugs in the 2022 version, I might wait a few months before purchasing it and adding it to my project.

By the way, I have another question. My unity project's folder has a lot of Chinese characters. Will this cause any problems?

 

Hey! Hot Reload should work on later versions just as well as on earlier versions.

You can consult troubleshooting for issues you might encounter with Chinese characters: https://hotreload.net/documentation/troubleshooting#watchman-process-ran-into-an-error.

I advise you to try Hot Reload for free. You can download it from our website and use the one-month free trial to evaluate: https://hotreload.net/download. Feel free to let us know about any issue you encounter during the free trial.

 

Connot recommand it more, you can easily find recommandation video on bilibili.

 

Hit @PencilBow, do you have callbacks for when a hot reload begins/finishes?

I'm generating code to initialize some data, and would like to wait for HR to finish compiling after the code is generated before I can use the generated code.

 

Hey, the `InvokeOnHotReload` attribute is what you're looking for. Hot Reload will invoke a method with this attribute whenever a reload finishes.

 

Thanks that seems to work. However I noticed something interesting, HR doesn't recompile files if comments in them change? Is there a way to manually invoke a patch/reload?

It makes sense that it doesn't for comments, but in my case I'd prefer if it did (the generated file has a new timestamp every time to force Unity to recompile it if HR was off)

EDIT: This is probably too nitpicky. I can just generate the timestamp as function to force it to patch the code.

 

Hi! It doesn't update code. Tried different watchers.

 

Hey, I would suggest killing `watchman` process in the Task Manager and restarting Unity project/Hot Reload.

 

I already tried this, it didn't help.

 

Hey, please reach out to us in our discord support channel: https://discord.com/invite/kgxAS4Bqxr or fill in the form on our website: https://hotreload.net/contact, and we will help you resolve the issue.
