Hello all. I am following this tutorial to make a n inventory. Pretty much followed closely (only difference is I am storing the inventory in a Game Instance rather than Character controller.) > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline.

I checked some questions about “Access violation - code c0000005” and it seems people suggest checking pointers, however it seems to unrelated for this situation. ? I would really appreciate some help about understanding he crush report here. It has been 2-3 days and I am kinda stuck. Here are my code files if you wish to look at them. https://www.dropbox.com/s/o2f0aa1tdb…yCode.rar?dl=0 I am using UE4 4.18.3 and VS 2017 with updates. Thanks and respects. ---

That’s a null pointer crash. Likely your AddItemToInventoryByID is accessing a nullptr. If you’re using that code in the tutorial, I’d change it to this: ```auto bool AInventoryController::AddItemToInventoryByID(FName ID) { **if (AInventoryGameState* GameState = Cast(GetWorld()->GetGameState()))** { UDataTable* ItemTable = GameState->GetItemDB(); FInventoryItem* ItemToAdd = ItemTable->FindRow(ID, ""); if (ItemToAdd) { // If a Slot- or WeightLimit are not needed remove them in this line if (Inventory.Num() < InventorySlotLimit && GetInventoryWeight() + ItemToAdd->Weight <= InventoryWeightLimit) { Inventory.Add(*ItemToAdd); ReloadInventory(); return true; } } } return false; } ``` Likely whatever gamemode your level is using, isn’t the one you expect. ---

It gives you the exact function and line of code where the code crashes. Line 19 of e:\ue4\r7\source\r7\spr7gamestate.cpp isnide ASPR7GameState::GetItemDB() method. You can even check the value you are trying to access (probably null or even uninitialized) if you are using a debuger (running through e.g. Visual Studio, Qt Creator, …). ---

Thanks mate. > [@NuLL3rr0r](#): > > It gives you the exact function and line of code where the code crashes.

Oh so it is really like that. Thanks mate.
