Calling a function from another actor using its object reference in c++ [Member is inaccessible]

[ReinPandora]

Ill try to make this quick. I am learning C++ and Unreal engine, and I am trying to transform this group of nodes into a single c++ function :

Here is the function I’m working on :

void AR_ChunkManager::UpdateEveryChunk(FIntPoint PlayerPos, TArray<AR_Chunk*>& ObjectArray, TArray<FIntPoint>& PosArray,
	TArray<FR_ChunkValues>& ValuesArray, FR_MeshValues& MeshValues, TArray<FR_LODValues>& LODArray,
	FR_NoiseMap& NoiseMap, TArray<FR_LODInfo> LOD)
{
	int32 i = 0;
	for (AR_Chunk* Chunk : ObjectArray)
	{
		FR_UpdatedValues UpdatedValues = FindUpdatedValues(PlayerPos, PosArray[i], LOD);
		Chunk->UpdateChunk(ValuesArray[i], MeshValues, LODArray[i], NoiseMap, UpdatedValues, true);
		i++;
	}
}

This is the function I want to call (in R_Chunk.h):

UFUNCTION(BlueprintCallable)
	void UpdateChunk(UPARAM(ref) FR_ChunkValues &ChunkValues, UPARAM(ref) FR_MeshValues& MeshValues,
		UPARAM(ref) FR_LODValues& LODValues, UPARAM(ref) FR_NoiseMap& NoiseMap,UPARAM(ref) FR_UpdatedValues& UpdatedValues, bool print);

Its giving me the error that the member in inaccessible, although it works fine in blueprints. Thank you!

try adding public: in your class in R_Chunk.h before the function declaration

Thanks, I completely forgot to check it!
