[Modes Extension Plugin] Spawn Landscape problem

Hello I want create landscape in editor, and attach Landscape Material, Landscape Hole material and weight data.

I stuck at spawning blank landscape, here’s my code:



            int width = 1024;
            int height = 1024;

            int quads_per_section = 63;
            int number_of_sections = 1;
            int components_x = 8;
            int components_y = 8;

            int new_width = quads_per_section * number_of_sections * components_x + 1;
            int new_height = quads_per_section * number_of_sections * components_y + 1;

            int offset_x = (new_width - width) / 2;
            int offset_y = (new_height - height) / 2;

            TArray<uint16> original_data;
            for (int w = 0; w < width; w++) {
                for (int h = 0; h < height; h++) {
                    original_data.Add(32767);
                }
            }

            TArray<uint16> data = LandscapeEditorUtils::ExpandData<uint16>(original_data, 0, 0, width - 1, height - 1, -offset_x, -offset_y, new_width - offset_x - 1, new_height - offset_y - 1);

            ALandscapeProxy *landscape = nullptr;
            FVector location = FVector(0, 0, 0);
            FRotator rotation = FRotator(0, 0, 0);
            landscape = (ALandscapeProxy*)(GEngine->GetWorld()->SpawnActor(ALandscape::StaticClass(), &location, &rotation));

            int layer_type = (int)ELandscapeImportAlphamapType::Additive;


            int quads_per_component = number_of_sections * quads_per_section;
            int size_x = components_x * quads_per_component + 1;
            int size_y = components_y * quads_per_component + 1;


            TArray<FLandscapeImportLayerInfo> infos;

            TMap<FGuid, TArray<uint16>> HeightDataPerLayers;
            HeightDataPerLayers.Add(FGuid(), data);
            TMap<FGuid, TArray<FLandscapeImportLayerInfo>> MaterialLayersInfo;
            MaterialLayersInfo.Add(FGuid(), infos);
            landscape->Import(FGuid::NewGuid(), 0, 0, size_x - 1, size_y - 1, number_of_sections, quads_per_section, HeightDataPerLayers, nullptr, MaterialLayersInfo, (ELandscapeImportAlphamapType)layer_type);
            landscape->SetActorScale3D(FVector(50,50,50));


Editor crash at line: ** landscape = (ALandscapeProxy*)(GEngine->GetWorld()->SpawnActor(ALandscape::StaticClass(), &location, &rotation));

**

How to properly initialize new landscape in editor in C++ plugin ?

Instead GEngine I used GetEditorMode() and now works :slight_smile:
ALandscape Landscape = GetEditorMode()->GetWorld()->SpawnActor<ALandscape>(location, rotation);*
GetEditorMode() is a nonstatic member reference and must be relative to a specific object in my case method in class inherited from FModeToolkit
