Hello,

i want to get the Display Cluster API in c++. There is already the Blueprint UDisplayClusterBlueprintLib::GetAPI | Unreal Engine Documentation
The class isnt tagged as a dll Export so i cant build any “Editor” configuration.

Is there a workaround or fix for this?

Thanks!

Hello,

I am also interested in this.
I am trying to get the Display Cluster API in C++, I currently have the following code :

//Get DisplayClusterAPI
TScriptInterface<IDisplayClusterBlueprintAPI> DisplayClusterBlueprintAPI;
UDisplayClusterBlueprintLib::GetAPI(DisplayClusterBlueprintAPI);

But I get an error when compiling :

unresolved external symbol “public: static void __cdecl UDisplayClusterBlueprintLib::GetAPI(class TScriptInterface &)”

I have included “DisplayCluster” in my build.cs file as follows :

PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "DisplayCluster" });

And included the header

#include "DisplayCluster/Public/Blueprints/DisplayClusterBlueprintLib.h"

but I still get the error and I don’t know why.

Hey! Has anyone figured this out?

Why do you want to get the Blueprint API instead of accessing the functionality directly:

IDisplayCluster::Get()

From there on, you can access the respective managers:

/**
	* Access to the device manager.
	*
	* @return Current device manager or nullptr
	*/
	virtual IDisplayClusterRenderManager* GetRenderMgr() const = 0;

	/**
	* Access to the cluster manager.
	*
	* @return Current cluster manager or nullptr
	*/
	virtual IDisplayClusterClusterManager* GetClusterMgr() const = 0;

	/**
	* Access to the config manager.
	*
	* @return Current config manager or nullptr
	*/
	virtual IDisplayClusterConfigManager* GetConfigMgr() const = 0;

	/**
	* Access to the game manager.
	*
	* @return Current game manager or nullptr
	*/
	virtual IDisplayClusterGameManager* GetGameMgr() const = 0;

	/**
	* Access to the DisplayCluster callbacks API
	*
	* @return Callbacks API
	*/
	virtual IDisplayClusterCallbacks& GetCallbacks() = 0;

These work fine on my end, just have to be a bit careful sometimes on which node you call them.
