[Solved]Debugging with Unity3 on Windows

Hi everyone,

I'm failing at debugging my game using MonoDevelop and Unity 3. I have installed the latest mono distribution (without xps and gtk) but the debug button keeps grayed out.

Does anyone have a hint how to set up my machine to be able to debug ?

Thanks and have fun...

 

I have the same problem. Maybe someone can help so ...

 

Until the right person appears and explains everything as needed, I'll try to help out.

Anyways, here are the simple steps:

1. Open MonoDevelop
2. Go Tools->Preferences, scroll down to Unity->Debugger
3. Set Editor Location
4. Now you need some scene to play with, create a basic scene, add some simple C# script
5. Execute Assets->Sync MonoDevelop Project, this will create *.sln file which is needed by MonoDevelop
6. Close UnityEditor
7. From the MonoDevelop, open up created *.sln file
8. Setup some breakpoints in your C# script
9. Run->Run With->Unity Debugger
10. The UnityEditor should open up
11. Press Play button
12. MonoDevelop should stop at the breakpoint you've setup

Hope that helps
:roll:

 

Thank you so much

It all works now *thumbsup*

 

O.k., I think, I have the wrong version of MonoDevelop.
Unfortunately the download link does not function. I get a 404 error for the Mac Version.

 

Btw., Those instructions were for MonoDevelop on Windows

But it should be similar for Mac also

 

Well it seems you need to download the version of MonoDevelop from the Unity guys. The "official" MonoDevelop has no Unity-Addin. Too bad that the Mac version download link is broken

 

Solved ... Thanks

 

I can't get the debugger to go at all. I mean, literally, when I start MonoDevelop.exe it simply disappears after the loading bar.

This is the Unity-provided link to MonoDevelop, running under Windows 7. Has anybody else had this problem or know what I'm missing?

 

Windows 7 32 bit or 64 bit?

 

I have the same problem.
I'm using Windows 7 64bit.
When I try to start it I get a message that there is something wrong with an addin.
After that it doesn't startup and simply disappears.
See the log.txt file.

 

I've ran MonoDevelop on a colleague's PC with windows 7 64 bit, and it runs okay.

I suggest to fill a bug report with detailed info maybe the problem is elsewhere

 

But was it the latest version that came with unity 3 beta 3?
Also when I istall MonoDevelop 2.4 from the official website it runs fine.

 

Yes, just in case re-downloaded from link provided in Unity Beta Test group and it ran okay.

So it's the latest

 

Ok, thanks for testing. I will see if I can fix it

 

I am having the same issue with MonoDevelop not starting on Windows 7 x64. I tried running it from where I zipped it, I installed the GTK# from the MonoDevelop home site and tried again. I tried moving the folder to "Program Files(x86)" and even tried installing MonoDevelop and dropping the in extra unity files with it.

Has anyone found a way to make this work or am I still missing something? I really want to use the debugger!

Thanks!

 

I've tried also to install it with no success
I'm using Win 7 64bit and first I got an un unhandled exception. After that I only see the splash screen and then it stops.
When I view the log.txt I see all kinds of errors like this one:
ERROR: There was an error while scanning assembly: C:\MonoDevelop_for_unity\bin\asprintf.dll expect assembly-manifest

Hope this information helps finding the solution.

 

Hi guys,
There was an issue with one of the windows builds that got released.
It will be fixed for the next beta.

As a workaround, you can remove duplicated dlls from the AddIns/ and AddIns/BackendBindings/ directories:
basically anything that's in bin/ shouldn't also be in AddIns/, and nothing from bin/ or AddIns/ should also be in AddIns/BackendBindings/

 

Never mind check the post above.

 

The downloaded MonoDev did not come with an installer. How is everyone installing. Are we supposed to install from MonoDevelop.com then replace the files with the ones from Unity?

Seems kinda silly

 

Tak, thanks. In the version of Mono Developer that comes with Unity b3 for windows, following Tak's instructions, I ended up with the following structure that works :

Not so complicated, just delete what is not on the list above

 

I deleted all the files that were not in the lists above but it didn't help.
When I check the log.txt (in C:\Users\myUserName\AppData\Roaming\MonoDevelop) I still see lots of errors. See attachment.

Anyone known what is going wrong?

Btw I'm using Windows 7 64bit

 

I found the solution. The make MonoDevelop work you need to install GTK for .NET (if you're using windows).
You can find it here: http://monodevelop.com/Download

 

Ok,

The Boo folder must be deleted if you are using C# in \MonoDevelop\Addins\BackendBindings else try to remove conflicting files.

As a side note to when you developers will release an install you should ask what language we will use or find a way for all of them to co-exist or you should rename your files so there is no conflicts. I am pretty sure no one will change the language anyway if a company has invested lots of energy in one.

Follow the instruction on how to debug found earlier in the post. Oh the joy I feel now...

 

I did the dll cleansing and set the preference. The ide opens up ok and I can set breakpoints. When I go to run/run however, I get no options, where I should get "Unity Debugger".

9. Run->Run With->Unity Debugger
10. The UnityEditor should open up

 

It would seem upon rebooting the machine the monodevelop has stopped working... this is strange. So it worked only one night for me !

Now i feel lonely...

 

I got mine working by doing deleting the duplicates, deleting the ..\Roaming\MonoDevelop entry, and disabling UAC. I left BOO in.

 

I can't seem to get this working. I tried from scratch several times deleting all the files I didn't see from that list (so much comparing back and forth I'm sure I made some mistakes). My log.txt is like 15 pages long of errors. I give up, mustn't waste any more of my Sunday!

Could anyone offer a .zip of the version that works instead? Or maybe a .bat file that deletes the right files that we can just run?

I guess it's back to UnityDevelop for now!

 

What are the symptoms? Does it load or die on the splash screen?

 

I had both monoDevelop and mono and libs installed prior to this, so desinstalling it helped. And i did a file to file perfect match of the files listed above in a previous post and trust me it works, you just have to take the time to check for each and if its not there remove it. When i did the file check with monodevelop installed it simply crashed, on uninstalling it, it probably removed the mono assemblys in the system files. Now that forces the application to load the one in the folders instead of the system folder.

 

Im having same problem.

Was the b3 monodevelop.zip different from the b4 one?
I didnt download the b4 one..and now I cant get back to its upgrade page :? (checking for updates doesnt send me there.)

-LW

 

I installed the new beta and so the mono develop that come with and all work in first pass without do nothing esle than simple install, so for those who have trouble , if you didn't download the b4 yet , give it a try it should fix all that, at least it did for me.

 

I installed beta 5 along with MonoDevelop on Windows XP. I followed the instructions, configured it correctly, created a solution, etc. MonoDevelop runs fine but when I try to launch Unity, it hangs and Unity never launches.

 

I had the same thing. I rebooted and then started Unity without monoDevelop and then ... started it with monoDevelop and it worked. I assumed some .dll was resident from running Beta4.

 

That doesn't work for me. It still hangs. Maybe it's because I have Unity 2.6 and 3 on the same machine. Although I've configured MonoDevelop to launch the Unity 3 executable.

Ok, I got it to work, but not the way described in the instructions.

If I use Run->Run With->Unity Debugger, it hangs and never launches Unity.

If I use Run->Debug, it works.

By the way, will the debugger work with Javascript or just C#?

-- Brian

 

Debugging works with JavaScript as well.

 

I've had the same problem with beta5, the quoted solution worked perfectly, thanks!

 

hello,
Will it be also possible to debug scripts using VS ?
