Custom GameState crashes Game in PIE

Development Programming & Scripting
1

Hi Guys,
most of the code regarding GameState is currently copied from the StrategyGame example, maybe that’s part of why it is going wrong. As soon as I start the game in PIE, the engine crashes. Unfortunately I cannot see any error message because symbols are missing.

This is my GameMode where I set the GameStateClass. Uncommenting the Set GameState Line causes the Crash:

#include "ProjectGrandStrategy.h"
#include "GSPlayerController.h"
#include "GSPlayerPawn.h"
#include "GSGameState.h"
#include "GSIngameHUD.h"
#include "ProjectGrandStrategyGameModeBase.h"


AProjectGrandStrategyGameModeBase::AProjectGrandStrategyGameModeBase(const FObjectInitializer& ObjectInitializer)
	: Super(ObjectInitializer)
{
	// Set Pawn
	DefaultPawnClass = AGSPlayerPawn::StaticClass();
	SpectatorClass = AGSPlayerPawn::StaticClass();

	// Set HUD
	HUDClass = AGSIngameHUD::StaticClass();

	// Set Player Controller
	PlayerControllerClass = AGSPlayerController::StaticClass();

	// Set Game State
	GameStateClass = AGSGameState::StaticClass();
}

And these are my GSGameState.h and GSGameState.cpp:

UCLASS()
class PROJECTGRANDSTRATEGY_API AGSGameState : public AGameStateBase
{
	GENERATED_BODY()

	AGSGameState();

public:
	FPlayerData* GetPlayerData(uint8 TeamNumber) const;

protected:
	mutable TArray<FPlayerData> PlayersData;
	
};

.cpp:

// Fill out your copyright notice in the Description page of Project Settings.

#include "ProjectGrandStrategy.h"
#include "GSGameState.h"


AGSGameState::AGSGameState()
{

}

FPlayerData* AGSGameState::GetPlayerData(uint8 TeamNumber) const
{
	if (TeamNumber != EGSTeam::Unknown)
	{
		return &PlayersData[TeamNumber];
	}

	return nullptr;
}

I guess I’m missing something very basic and/or obvious, please bear with me.
Thanks for your time and help!

Seems you forgot to fill the TArray PlayersData with FPlayerData instances somewhere.

I’m such a dummy. I copied this to learn / use it, but I gotta be more careful when doing that. Thanks Wurmloch83!
Can you convert this to an answer so I can give you some sweet points?
