[Released] Panic Button - stop infinite loops in 1 second

Hi everyone!
I'm happy to present my editor extension which I think will be useful to you:

Panic Button
http://u3d.as/hpe
​

Basically, it solves what you encounter when you accidentally enter an infinite loop during development.
When it happens, the Unity editor is frozen and you cannot do anything - the Stop/Pause buttons are unresponsive as well as the option to save your project or close Unity properly.

When the Panic Button is installed, fortunately all you have to do is to press it (Shift+Escape by default), and the faulty script is aborted, the game is paused, and Unity is immediately responsive again.

It also prints a stack trace in the console, allowing you to locate the infinite loop easily.

So now, when you encounter this problem, all you have to do is to simply press the panic button - that's all, problem solved instantly.

Watch the video below to see it in action!

​

This functionality was requested here on the feature requests forum : http://feedback.unity3d.com/suggestions/editor-panic-button-for-infinit

There had to be a better way to handle this issue, so that's why I created this tool to help you save time while you are coding and debugging.
And I’ve implemented the ideas discussed in the link above, such as:

• Pausing the game and printing a stack trace
  
• Support for game scripts and editor scripts
  
• Optional watchdog timer to abort the game after a few seconds of freezing

You can get Panic Button on the Asset Store here.
Price : $10

I hope that you will enjoy it, and I'd be happy to know what you think about it!
Comments, questions, bug reports, or feature requests are welcome - I'm here to help.

Thanks!

 

This has been very handy. Thanks

 

You're welcome. I'm happy to have been helpful.
Please consider leaving a review on the Asset Store if you liked it.

 

Update 1.0.2 has been published
It fixes a bug that would sometimes report incorrect line numbers in stack traces.

 

Purchased, but not working. Cleared my game objects properties (fixed by following uninstall instructions). When installed I can't execute game. Would love for it to work.

Hi!
Thanks for reporting the problem.

Does it work with an empty project? Or is it failing just for your project?

 

I have the same error. Did not repro on an empty project.

 

Thanks a lot for notifying me about this problem!
I'm aware of a few edge cases causing issues with the plugin and I'm currently working on an update to fix those.

 

It was this some script in this asset package that caused it for me: https://www.assetstore.unity3d.com/en/#!/content/29270

 

Hello.


Hello. I bought this asset not long ago. It seems to have problems with an other free asset that I have, called Isolationist.
This asset has no Dlls, but it registers itself on some of Unity's callbacks, like PlayModeStateChange.
Any ideas on how to fix it?

 

What is correct procedure to uninstall PanicButton? I have removed the folder but somehow references are lingering?

 

Hi there! Do you have any plans to make it compatible with unity 2019?

 

This will not get updated anymore, so I made my own. Its called Emergency Exit and I have a unity forum post and its on the assetstore.
