Use Unreal Unattended CRC

Last updated on October 20, 2023

Overview

When you start the Unreal Engine or your Unreal Engine game, you can run command line arguments that tell the Unreal Engine to do or not do certain actions or events. One of these commands is the -unattended command.

You can use the -unattended command to enable a playing mode in which any action or event that needs feedback from the user is disabled. This enables AccelByte Development Toolkit (ADT) to still run and automatically send the crash data to the URL specified as the DataRouteURL in your DefaultEngine.ini file.

備考

This guide shows you how to enable -unattended mode in the Crash Reporter Client (CRC).

Enable unattended mode in Crash Reporter

To enable the '-unattended` command in the Crash Reporter for your game, follow these steps:

  1. Add this section to the DefaultEngine.ini file for your game.

    [CrashReportClient]
    bAgreeToCrashUpload=True
  2. Add this section into the DefaultEditor.ini file for your game.

    [/Script/UnrealEd.CrashReportsPrivacySettings]
    bSendUnattendedBugReports=True
  3. Add -unattended argument to the command line parameter on your server management tool before launching the game server. For example:

    MyGameServer.exe MyGameMap -unattended

Additional Steps for Unreal 5.1+

Follow these steps:

  1. Go to Engine/Config/Linux directory and open LinuxEngine.ini file.

  2. Modify this configuration key to true.

    [CrashReportClient]
    bAgreeToCrashUpload=false

Behavior on a Linux machine​

The following table shows the behavior when you choose whether to start the CRC based on the DefaultEngine.ini setting for bSendUnattendedBugReports or bAgreeToCrashUpload and whether we are unattended.

Bypass Unreal Engine Licensee Status

For Licensee Version of Unreal Engine, you must add the following Engine modification for Linux platform to force the engine to send the crash report regardless of the Licensee status.

  1. Go to Engine/Source/Runtime/Core/Private/Unix/Unix directory and open the UnixPlatformCrashContext.cpp file.

  2. Add this string to the file.

    if (/*BuildSettings::IsLicenseeVersion()*/ false && !UE_EDITOR)
{
// do not send unattended reports in licensees' builds except for the editor, where it is governed by the above setting
bSendUnattendedBugReports = false;
bAgreeToCrashUpload = false;
bSendUsageData = false;
}
