Wander Operation
WanderOperation::Run()
CalculateEdgeList()
FindNearestWaypoint() finds start point
GetActiveLocate() finds end point
FindEdgeRoute() finds the route between start and end
dest = GetNextPathPoint() gets the next path point (not the current one) and returns it
StartMoveTo(dest)
NPC Brain
APlaneShiftGameState::BeginPlay()
calls psNPCManager::Initialize()
calls ReadNPCsFromDatabase()
select * from sc_npc_definitions
populates npcs TMap
spawnManager->RepopulateLive();
LoadAllNPCCharacterData
SELECT characters.* where npc_spawn_rule>0
char = SpawnActor()
char->Load()
if (IsNPC()) psAIController->SetBrain( using npcs TMap above)
When a perception happens it goes through:
psNPCManager::TriggerEvent()
checks all reactions with this event and it finds also the brains without pawn associated, so I added a check there to skip
Main engine loop on startup
MyProjectServer.exe!UIpNetDriver::InitListen(FNetworkNotify * InNotify, FURL & LocalURL, bool bReuseAddressAndPort, FString & Error) Line 152 C++ MyProjectServer.exe!UWorld::Listen(FURL & InURL) Line 3927 C++ MyProjectServer.exe!UEngine::LoadMap(FWorldContext & WorldContext, FURL URL, UPendingNetGame * Pending, FString & Error) Line 8983 C++ MyProjectServer.exe!UEngine::Browse(FWorldContext & WorldContext, FURL URL, FString & Error) Line 8144 C++ MyProjectServer.exe!UGameInstance::StartGameInstance() Line 262 C++ MyProjectServer.exe!UGameEngine::Init(IEngineLoop * InEngineLoop) Line 465 C++ MyProjectServer.exe!FEngineLoop::Init() Line 1967 C++ MyProjectServer.exe!GuardedMain(const wchar_t * CmdLine, HINSTANCE__ * hInInstance, HINSTANCE__ * hPrevInstance, int nCmdShow) Line 138 C++ MyProjectServer.exe!WinMain(HINSTANCE__ * hInInstance, HINSTANCE__ * hPrevInstance, char * __formal, int nCmdShow) Line 191 C++
Open level command
When you execute the "open" command from console, it will queue the travel to open the map:
MyProject2.exe!UGameInstance::HandleOpenCommand(const wchar_t * Cmd, FOutputDevice & Ar, UWorld * InWorld) Line 295 C++ MyProject2.exe!UGameInstance::Exec(UWorld * InWorld, const wchar_t * Cmd, FOutputDevice & Ar) Line 323 C++ MyProject2.exe!UGameViewportClient::Exec(UWorld * InWorld, const wchar_t * Cmd, FOutputDevice & Ar) Line 2014 C++ MyProject2.exe!ULocalPlayer::Exec(UWorld * InWorld, const wchar_t * Cmd, FOutputDevice & Ar) Line 1457 C++ MyProject2.exe!APlayerController::ConsoleCommand(const FString & Cmd, bool bWriteToLog) Line 350 C++ MyProject2.exe!UConsole::ConsoleCommand(const FString & Command) Line 394 C++ MyProject2.exe!UConsole::InputKey_InputLine(int ControllerId, FKey Key, EInputEvent Event, float AmountDepressed, bool bGamepad) Line 651 C++ MyProject2.exe!UConsole::InputKey(int ControllerId, FKey Key, EInputEvent Event, float AmountDepressed, bool bGamepad) Line 1062 C++ MyProject2.exe!UGameViewportClient::InputKey(FViewport * InViewport, int ControllerId, FKey Key, EInputEvent EventType, float AmountDepressed, bool bGamepad) Line 265 C++
Then at the next tick it will do this:
MyProject2.exe!UEngine::Browse(FWorldContext & WorldContext, FURL URL, FString & Error) Line 8161 C++ MyProject2.exe!UEngine::TickWorldTravel(FWorldContext & Context, float DeltaSeconds) Line 8311 C++ MyProject2.exe!UGameEngine::Tick(float DeltaSeconds, bool bIdleMode) Line 812 C++ MyProject2.exe!FEngineLoop::Tick() Line 2257 C++ MyProject2.exe!GuardedMain(const wchar_t * CmdLine, HINSTANCE__ * hInInstance, HINSTANCE__ * hPrevInstance, int nCmdShow) Line 142 C++
Collision Tests
Inside ApsItemActor::ApsItemActor() no special code
Character collides with items
Inside ApsItemActor::ApsItemActor()
mesh->SetCollisionProfileName("NoCollision");
mesh->SetCollisionEnabled(ECollisionEnabled::NoCollision);
Character does not collide with items
Inside EntityManager::CreateItem() after SpawnActor
mesh->SetCollisionProfileName("NoCollision");
mesh->SetCollisionEnabled(ECollisionEnabled::NoCollision);
Character collides with items (code seems to have no effect)
Quest interaction sequence
When the player is clicking on the talk icon , this happens, and sends back to the client all the possible quest options:
APlaneshiftPlayerControllerBase::TalkInteraction()
ApsCharacter::ShowPopupMenu
NpcDialogMenu::ShowMenu
eventManager->SendDialogMenuMessageDelayed
When the player is selecting one option in the npc bubble menu, he sends a chat message to the NPC
APlaneshiftPlayerControllerBase::SendChatMessage
ChatManager::HandleChatMessage with type CHAT_NPC
NpcResponse::ExecuteScript (based on the response found, we execute the script, which may include a number of steps, like say something, do an animation, etc...)
