Not compile function ALandscapeProxy::UpdateBakedTextures()

wanted to remodel grass in landscapes during the game.
here is what I wrote:

#include "LandscapeProxy.h"
#include "GameFramework/Actor.h"
#include "rClimatManager.generated.h"
UCLASS()
class HUMANMOUNT_API ArClimatManager : public AActor
{
	GENERATED_BODY()
public:	
	ArClimatManager();
protected:
	virtual void BeginPlay() override;
public:	
	virtual void Tick(float DeltaTime) override;
	 UFUNCTION(BlueprintCallable) void UpdateLandscape(ALandscapeProxy* TereinLandscape){
	     if(TereinLandscape){ TereinLandscape->UpdateBakedTextures(); }
	} 
};

thought to make a function wrapper, but still it went wrong and visual studio no compiles

Your ALandscapeProxy class needs to have an UpdateBakedTextures function.

Add

public:
void UpdateBakedTextures();

In LandscapeProxy.h (inside the class). Then add

void ALandscapeProxy ::UpdateBakedTextures()
{
    // add the code you want here
}

In LandscapeProxy.cpp.

ALandscapeProxy it’s an engine class in it and so is the function UpdateBakedTextures()

Hi Velmir, you are getting a linker error because you need to add a dependency for the “Landscape” module in your Build.cs file.
Unfortunately this module seems to be editor only, so you won’t be able to use it in a packaged build at runtime.

thanks for the reply.
Of course, it is a pity that in the standard assembly I will not be able to do this.
