Create a new project (optional) #

Create a new project

Set up PragmaSDK for Unreal #

  1. Create a Plugins folder in the root of your Unreal project.

  2. Copy pragma-engine/sdk/unreal4/update-pragma-sdk.sh to the Plugins folder you just created.

  3. Modify the update-pragma-sdk.sh script as follows:

  • Uncomment SOURCE_ENGINE_RELATIVE_FOLDER and change the value to point to your pragma-engine repo.

  • Uncomment TARGET_PRAGMA_SDK_DIR and change the value to PragmaSDK. This creates a PragmaSDK folder under the current directory (Plugins).

  1. Run update-pragma-sdk.sh in Git Bash from the directory where you copied the script. Confirm that the PragmaSDK folder now exists in your Plugins directory.

Update PragmaSDK for Unreal #

Whenever you make changes to Pragma Engine or update the code, you’ll want to update the PragmaSDK Unreal plugin folder. Re-run the update script command from your Unreal Plugins directory:

update-pragma-sdk.sh

Configure the Pragma SDK #

  1. From your Unreal project base folder, open Source/[Project Name]/[Project Name].Build.cs and add PragmaSDK and PragmaSDKAux to the PublicDependencyModuleNames array:

    PublicDependencyModuleNames.AddRange(new string[] { ..., "PragmaSDK", "PragmaSDKAux" });

  2. From your Unreal project base folder, open Config/DefaultGame.ini and add the following configuration information to the bottom:

[/Script/PragmaSDK.PragmaSdkConfig]
BackendAddress="http://127.0.0.1:10000"
ProtocolType="WebSocket"
GameClientVersion="GameServerVersion1"
When configuring the SDK for a game server, you should use the PartnerBackendAddress config and port 10100 (partner port).

(Optional) Add the following to Config/DefaultEngine.ini to enable logs for every inbound and outbound RPC with payloads.

[Core.Log]
LogPragma=Verbose
