Steamworks for Unity

Thanks SteveB, it works now! I had put it in the /Assets folder.

 

Yay!!! You're welcome, and yea I wish there was a more robust Unity-Steam community here. It's surprising since I suspect quite a few people are making PC games, and sure while they may not want to use Steam, I have to believe a lot do so...

...here's hoping if we keep talking about it it will happen!

Cheers

-Steven

 

Yup, getting the same Sparty.

 

Anyone has an example of how to use Steamworks.SteamInterface.User.GetAuthSessionTicket (IntPtr ticket, int maxTicket)? I can't seem to get an actual session ticket out of it...

Thanks!

 

As I'm not at the point of considering integrating steam yet or even looked into the system for it.

Is it not more of a case of people either rolling their own or waiting till they through greenlight before they start to consider integrating steamworks.

 

Hi There,

Does anyone have already used the UGCQuery ?

I'm with troubles on this, my game is on Steam, users can share Maps (Steam Workshop), but since the last update on Steam DLL this function doesn't work anymore.
The original code was based on "SteamInterface.Cloud.EnumeratePublishedWorkshopFiles" and was working until de end of 2013.
This Cloud functions, and workshop work seems to be changed to the UGCQuerys, (SteamInterface.UGC.CreateQueryAllUGCRequest), but I didn't found any documentation on Ludosity site, and I didn't get a repply on this.

Any help would be welcome,

Thanks in advance.

 

Is there any news on the 64-bit linux version? My customers are crying out for linux64. Unity and Steamworks SDK both support, but I cannot ship due to Ludosity wrapper not.

Any updates on when it should/could be coming as the docs states it's in the pipeline, stay tuned (or similar).

Cheers in advance,
Matt.

 

Any ideas why I'm getting NoAuth as the response from SteamInterface.User.UserHasLicenseForApp()? How do I verify a license?

Thanks!

 

Hello,

It would be nice if Ludosity tell us about their intentions on continue supporting this plugin.

It's being hard to have any kind of answer or support from them since the past month, or more.

If they don't want to continue supporting it, I would recomend to stop selling the asset then.

 

Just bought this and wondering if it was a mistake. It's not a very good sign when the sample code won't even compile. Especially considering how little there is of it. Sparty, I just put a .AsUInt64 after the mismatched IDs in order to get it to compile. No idea if that's good enough.

 

I'm getting NoAuth from UserHasLicenseForApp as well. I've confirmed the App ID is correct. SteamID also looks correct (At least it's a big number and not zero.) Pretty much dead in the water if steam thinks I don't own the app. I also have some idea that my AppID is good because I've already pushed a build and launched it from steam.

This seems like such a basic thing, I wonder if there's something going on at Steam, Then again Knil has been waiting 2 days on the same problem and the sample didn't even compile.

Tomorrow morning, I'll be off to something else I guess. Does Asset Store do refunds?

 

I'm using
SteamInterface.Apps.IsSubscribedApp(SteamInterface.AppID);

Now to check whether they own the game now since I was getting no auth the other way. Just be sure to note this is just a client side check so it isn't 100% secure.

 

Does anyone know if this works with Unity 3.5.x?
I need to know this before I buy.

Update your plugin. It gives me compile errors on latest Unity pro.

 

Hi!

I'm trying to use the IsSubscribedApp method as mentioned by Knil to tell if a player bought our DLC or not, but I get an EntryPointNotFoundException and don't really understand what am I doing wrong.

I have a static class for the SteamAPI call handling:

Code (CSharp):

1. public class SteamAPI : MonoBehaviour
2. {
3.     static SteamAPI o_instance;
4.     Steam SteamInterface { get; set; }
5.     public bool b_init = false;
6.  
7.     public static bool Initialize()
8.     {
9.         (...)
10.  
11.         o_instance.b_init = true;
12.     }
13.  
14. (...)
15.  
16.     public static bool IsDLCUnlocked()
17.     {
18.         bool b_result = false;
19.  
20.         if(o_instance.b_init)
21.             b_result = o_instance.SteamInterface.Apps.IsSubscribedApp( new AppID( 123456 ) );
22.         else
23.             Debug.LogWarning("SteamAPI: failed to check app subscription, SteamAPI is not initialized.");
24.  
25.         return b_result;
26.     }
27. }

The error is:
EntryPointNotFoundException: Apps_IsSubscribedApp
ManagedSteam.Implementations.Apps.IsSubscribedApp (AppID appID)

Every help welcome!

 

Check out the example code Steamworks.cs and the awake function you should only need to call:

SteamInterface.Apps.IsSubscribedApp(SteamInterface.AppID);

You don't need to get an instance of your class.

 

Thanks for the quick answer!

The whole script is made static before by a previous programmer, so the instance is needed. Achievement handling is working okay so it shouldn't be a problem. Or do this particular function work in a different way and there is no way it would work with a static call?

And if I call it with SteamInterface.AppID it would mean the app ID of the current app, not the one I want to check for, wouldn't it?

 

we just grabbed it for a project, but I can't even figure out where to start.

this is definitely not a 'one step' integration by any stretch.

documentation is terrible, almost worse than not having docs at all.

For those that have it working - do I really need to make 3 copies of my project with separate DLL's for this package to work?

There are so called 'startup projects' for mac / linux / windows that appear (to me) to be bare bones sample unity projects to get started with, but there is no documentation about what to do with them or any explanation how they are to be used, etc.

very disappointed at this stage.

 

@Sparty - I fixed those compile errors by doing this:

if (value.GameID.AsUInt64 == Steamworks.SteamInterface.AppID.AsUInt64)

In both cases, but to be honest I have no idea if this will actually work because I don't even know how to test the game or figure out what else I'm supposed to be doing. If I figure anything out, might post it up just so I can remember later.

 

can anyone tell me what I'm supposed to put for the AppID? I can't even figure out the first most basic step. This is ridiculous. Is it possible to test the game from the Unity editor or do I have to make a build to test if it's working?

 

Ok think i'm slowly making progress.

Had to add this to the 'Steamworks.cs' file at the start of the OnGUI() function:

private void OnGUI()
{
if( SteamInterface == null)
return;

because it was just blowing up because Steamworks hadn't been initialized yet.

ugh.

 

gekidoslair:
You don't have to make three projects, just import the plugin to your project.
AppID comes from steam, if you create your app there, you'll be given an appID.
You can test from the editor, just make sure that the steam app is running.

 

Now about my problem: If I call some function of SteamInterface.Cloud or SteamInterface.Stats, it works, but any call from SteamInterface.Apps gives me the same EntryPointNotFoundException. What can be wrong?

 

Ok, this is getting even more strange. It works on my college's PC, but not on my iMac. What's causing this?

 

Thanx LionTR - think I have it figured out. sure would have been nice to have some better docs from Ludosity.

 

Their philosophy is to not have any docs because all the functions are described in the steam docs (or not...) and they only use those... Still some more usage examples would be helpful.

 

Fix this!

 

Fix it!! For me is an absurd to pay so much for a plugin and it comes with compile errors. This is incredible.

 

Hi all,

I got a bit sick of the process of building, applying DRM and uploading builds, so I wrote an editor window to help.

Use at your own risk - I won't be supporting it at all, and take no responsibility if it deletes your C drive. (Seriously though - it will do a recursive delete of whatever you tell it is your content folder and build path, so be a bit careful).

Script is attached, just dump it in an editor folder and it should appear in your Windows menu. Fill in all the blanks (they get cached in EditorPrefs), see the attached image for how mine's set up.



If anyone from Ludosity wants to clean it up and include it with the wrapper, you're more than welcome!

Hope it's useful to someone.

 

yes,we need the update please!!!

 

I have the same problem. An update might be good.

 

Hi,

Did anyone try to create a GameServer on his game?

We never received the SteamServersConnection callbacks after calling the IGameServer.LogOnAnonymous(). Also, ServicesGameServer.Initialize() returns true in editor and an exception (ManagedSteam.Exceptions.SteamInitializeFailedException: SteamInitializeFailed) on standalone builds.
(FYI, lobby callbacks are correctly fired in editor and standalone build)

I would like to know if the GameServer feature works in editor, if I have to test on standalone build or if I have to upload my build to test through the Steam client.

Any help would be welcome,
Thanks in advance.

 

Just an FYI, there is an open-source Steamworks library that is actually being supported and worked on regularly. From what I can see on the Steam forum, this seems to be the main integration library that alot of people are migrating to.

Don't mean to dis Ludosity's system, but an open-source community-supported library wins for me, even after spending the money on the Ludosity library.

Migration is fairly easy, depending on how much work you've already done:

Core Library:
https://github.com/rlabrecque/Steamworks.NET

Example project:
https://github.com/rlabrecque/Steamworks.NET-Example

CSteamworks ABI wrapper that the core library uses (not required if you are just using the library, but good to know that the source is available):
https://github.com/rlabrecque/CSteamworks

Haven't had any issues with integration myself, and it 'just works' so far.

Hope this helps someone.

 

Hi guys, i have a problem using the wrapper on the Macbook, the game works fine in the Unity editor with the steam wrapper, but when I test out on the standalone builds, it can't seem to find the DLL files, "SteamAPIWrap". I've checked, but the file is there, so I'm not sure how to proceed here on.

 

I've gotten this working 100% on PC and released to a dev test but trying to build to OSX or using it on my MacBook with OSX isn't working either. Followed the PDF exactly for file structure and copied over the right libsteam_api.dylib to the project and still getting DllNotFoundException: SteamworksNative

 

What has happened with this product. The earlier posts indicate it cost $300, but now it is free on the Asset store. Is the developer still supporting this package?

 

It's gone free. I don't think so. In this case, better use rlabrecque's Steamworks.NET mentioned above.

 

Did you ever get a fix for this? I'm running into the same problem.

 

Same problem. Did you ever work this out?

 

I took the plunge and converted my game to work with this library, but I'm getting strange out-of-memory errors when I quit the game now. They were not there before changing over to steamworks.net.

Edit: The error I'm getting is this:

Fatal error!
CheckDisalowAllocation. allocating memory when it is not allowed to allocate memory.​

 

We have such problem in Anoxemia, but we fixed it. If anyone is interesting I can make a video tutorial.

 

Sounds like a great idea!

 

How did you resolve this? I'm having the same problem/error on Mac build.

 

I would love to see your solution. I'm having the same problem with DllNotFoundException: SteamworksNative on Mac build.

 

Here it is:

 

Thanks for this Ludosity SteamWorks !
This is actually for free now on the assetstore and you don't need Unity Pro to use this !
found here: http://u3d.as/content/ludosity/ludosity-s-steamworks-wrapper/2qg

 

Thanks!

 

JFYI: I switched to the Steamworks.NET wrapper and it worked first try on all three platforms (Windows/OSX/Linux).

 

Somebody does uses Steam Auto-Cloud?

How to make it use the LocalLow folder in Windows?
