How to

First you will need to download the binaries from Discord. Head over to Discord Developer Portal and download Discord Game SDK.

After downloading, open the zip file and extract the library files from the lib/x86_64 folder to the following folders of this plugin:

• discord_game_sdk.dll and discord_game_sdk.dll.lib into Source/ThirdParty/discord-files/Win64/
• discord_game_sdk.bundle and discord_game_sdk.dylib into Source/ThirdParty/discord-files/Mac/
• discord_game_sdk.so into Source/ThirdParty/discord-files/Linux/x86_64-unknown-linux-gnu/ and rename it to libdiscord_game_sdk.so

After copying the binary files, open the cpp folder inside the zip file and extract all the contents to Source/DiscordUE4/discord-files folder.

Now you are good to go.

Compile error when using as Engine Plugin

In Windows, with the latest SDK there are chances you might encounter compile errors when using this plugin as an Engine plugin. You might see the following errors:

warning C4005: 'TEXT': macro redefinition
error C4668: '_WIN32_WINNT_WIN10_TH2' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
error C4668: '_WIN32_WINNT_WIN10_RS1' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
error C4668: '_WIN32_WINNT_WIN10_TH2' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
error C4668: '_WIN32_WINNT_WIN10_TH2' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
error C4668: '_WIN32_WINNT_WIN10_RS2' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
error C4668: '_WIN32_WINNT_WIN10_RS2' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'
...

This is because of including windows.h header file in Discord files. To fix it follow the steps below:

1: Open ffi.h and replace

#include <Windows.h>

with this:

#include "Runtime/Core/Public/Windows/AllowWindowsPlatformTypes.h"
#include "Runtime/Core/Public/Windows/MinWindows.h"
#include "Runtime/Core/Public/Windows/HideWindowsPlatformTypes.h"

2: Open types.h and remove #include <Windows.h>

Both files can be found under discord-files folder.
