Hello
First time doing a plugin and trying to spawn an empty Landscape using the code below.
But my method of spawning the Landscape is not compiling giving: error LNK2019: unresolved external symbol

Any suggestions on what might be wrong?

UWorld* World = nullptr;
	
		// We want to create the landscape in the landscape editor mode's world
		FWorldContext& EditorWorldContext = GEditor->GetEditorWorldContext();
		World = EditorWorldContext.World();

	ALandscape* Landscape = World->SpawnActor<ALandscape>(FVector(0.0f, 0.0f, 0.0f), FRotator(0.0f, 0.0f, 0.0f));

Hi, did you include the Landscape module in the module dependencies of your plugin’s build.cs file?

I had not included it, but adding it did not help.

But maybe I did it wrong, seems that I’m lacking som understanding of this.

PrivateDependencyModuleNames.AddRange(
			new string[]
			{
				"Projects",
				"InputCore",
				"EditorFramework",
				"UnrealEd",
				"ToolMenus",
				"CoreUObject",
				"Engine",
				"Slate",
				"SlateCore",
				"Landscape", //I added this, is it correct?
				// ... add private dependencies that you statically link with here ...	
			}
			);

Yes you added it correctly. And it compiles for me (when putting your code above into an actor), so I’m not sure what could be wrong. I created a new blank c++ project, then a new blank plugin. Then I added an actor to that plugin and inside the .cpp file of the actor included

#include "Landscape.h"
#include "Editor.h"

and in the BeginPlay added

UWorld* World = nullptr;

// We want to create the landscape in the landscape editor mode's world
FWorldContext& EditorWorldContext = GEditor->GetEditorWorldContext();
World = EditorWorldContext.World();

ALandscape* Landscape = World->SpawnActor<ALandscape>(FVector(0.0f, 0.0f, 0.0f), FRotator(0.0f, 0.0f, 0.0f));

And I added “Landscape” and “UnrealEd” to the PrivateDependencyModuleNames of the Build.cs file of the plugin, now it looks like

PrivateDependencyModuleNames.AddRange(
	new string[]
	{
		"CoreUObject",
		"Engine",
		"Slate",
		"SlateCore",
		"Landscape",
		"UnrealEd"
		// ... add private dependencies that you statically link with here ...	
	}
	);

Thank you for taking the time to look into this!
After I deleted binaries and restarted it compiles!
Cheers!
