How to #include my own header into the game?

I'm trying to include my Header with helpful functions into my unreal project in order to be able to include it in many other .h classes generated from inside the Editor so that they all can access them, but I am getting a lot of Errors... This is my .h file created from inside VS which I would like to use inside my project: #pragma once #include "Engine/World.h" #include "Classes/Kismet/KismetSystemLibrary.h" #include "WormGameMode.h" #include "WormGameMode.generated.h" //Given a position in the world, returns [row][column]ID inside the GridSlotsOccupiedMap grid. //FVector(0.f,0.f,0.f) is the center inside the 2D Array, the 2DArray is expected to have and ODD number of elements. UFUNCTION(BlueprintPure, Category = "Grid") void WorldLocationToGridID(AWormGameMode* GameMode, FVector Location, int& Row, int&Column) { int RowMiddleID = (GameMode->GridHeight / GameMode->GridBlockSize) / 2; int ColumnMiddleID = (GameMode->GridWidth / GameMode->GridBlockSize) / 2; int GridBlockSize = GameMode->GridBlockSize; //------------------------------------------ Row = -Location.Z / GridBlockSize + RowMiddleID; Column = Location.X / GridBlockSize + ColumnMiddleID; } //Display red wireframe cubes at the occupied position in the grid marked inside GridSlotsOccupiedMap UFUNCTION(BlueprintCallable, Category = "Debug") void DebugMarkOccupiedBlocks(AWormGameMode* GameMode) { TArray<TArrayBool> GridSlotsOccupiedMap = GameMode->GetGridSlotsOccupiedMap(); int GridWidth = GameMode->GridWidth; int GridHeight = GameMode->GridHeight; int GridBlockSize = GameMode->GridBlockSize; int XMiddleID = (GridWidth / GridBlockSize) / 2; int YMiddleID = (GridHeight / GridBlockSize) / 2; //----------------------------------------------- for (int row = 0; row < GridSlotsOccupiedMap.Num(); row++) { for (int column = 0; column < GridSlotsOccupiedMap[0].BoolRow.Num(); column++) { float X = (-XMiddleID + column) * GridBlockSize; float Z = (YMiddleID - row) * GridBlockSize; FVector Center = FVector(X, 50.f, Z + GridBlockSize/2); if (GridSlotsOccupiedMap[row][column]) { UE_LOG(LogTemp, Warning, TEXT("Block[%i][%i] is occupied"), row, column) UKismetSystemLibrary::DrawDebugBox(GetWorld(), Center, FVector(5.7f, 5.7f, 5.7f), FColor::Red, FRotator::ZeroRotator, 0.f, 0); } } } } As you see I've included #include "WormGameMode.generated.h" as instruction from a topic I've found online, also I've Cut/Pasted it from the Intermediate/ProjectFiles folder where VS created it and pasted into Worm/Source/Worm folder.
