Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[Closed] Steam API disabled! shipping version is server and client at same time?

Hi guys,

In the last 4 days I searched in every post, every tutorial, every wiki, doc or something, but nobody knows whats happening.

I follow step-by-step this tutorial:

https://docs.unrealengine.com/latest/INT/Programming/Online/Steam/index.html https://wiki.unrealengine.com/Steam,_Using_the_Steam_SDK_During_Development

changing DefaultEngine.ini properly

 ;others archievements removed 
 Achievement_0_Title="First Blood"
 Achievement_0_LockedDesc="This Archievement is not for you. Thanks Oblivion. Die a first time."
 Achievement_0_UnlockedDesc="Die a first time"
 ;others archievements removed


          if ((Target.Platform == UnrealTargetPlatform.Win32) || (Target.Platform == UnrealTargetPlatform.Win64))
                 UEBuildConfiguration.bCompileSteamOSS = true;
                 if (UEBuildConfiguration.bCompileSteamOSS == true)


in construct method added

 bUsesSteam = true;

And in Standalone Game steam works fine.

But in shipping build show this message:

 UE4Editor-Cmd: [2016.01.05-04.25.23:668][  0]LogOnline:Display: STEAM: Loading Steam SDK 1.32
 UE4Editor-Cmd: [2016.01.05-04.25.23:668][  0]LogOnline:Warning: STEAM: check if steam api is enabled

Failed to initialize Steam, this could be due to a Steam server and client running on the same machine. Try running with -NOSTEAM on the cmdline to disable.

How can I set my game is only a Game without Server?

I'm compiling in a WindowsNoEditor mode, following this steps: https://docs.unrealengine.com/latest/INT/Engine/Deployment/Releasing/index.html

My engine version is 4.10.2 from github.


my game is this: http://store.steampowered.com/app/378930/

Product Version: UE 4.10

Addicional information.

im my game.target.cs is set to Game, not server or client. Type = TargetType.Game;

 using UnrealBuildTool;
 using System.Collections.Generic;
 public class ProjectPesadeloTarget : TargetRules
     public ProjectPesadeloTarget(TargetInfo Target)
         Type = TargetType.Game;
         bUsesSteam = true;
     // TargetRules interface.
     public override void SetupBinaries(
         TargetInfo Target,
         ref List<UEBuildBinaryConfiguration> OutBuildBinaryConfigurations,
         ref List<string> OutExtraModuleNames
         OutExtraModuleNames.AddRange( new string[] { "ProjectPesadelo" } );

Is steam running on your machine? The steam client? Do you have any other games open that use steam?

avatar image jasielmacedo Jan 05 '16 at 01:31 PM

Yes, steam client is running and no, I've no game opened. But I made a new shipping build after you said, closing steam client, but not changed

Is strange, because in Standalone game steam works properly, with archievements and all

I accidentally solve that problem.

Simple: in shipping build process. Steam shutting down.

After process finished. go to:


and paste a file called steam_appid.txt or create one.

and finally, problem solved. Steam pop-up comes up and everything works again.
