(UE4) 언리얼 엔진 Navigation System Config

네비게이션 시스템을 이용한 Config 수정

UWorld *world = GEditor->GetEditorWorldContext().World();
UNavigationSystemV1* NavSystem = UNavigationSystemV1::GetCurrent(world);
 
    
TArray<FNavDataConfig> supportedAgents;
supportedAgents = NavSystem->GetSupportedAgents();
 
bool isOverlap = false;
for (FNavDataConfig sa : supportedAgents)
{
    UE_LOG(LogTemp, Display, TEXT("NavSystem :: %s"), *sa.Name.ToString());
        
    if (sa.Name.Compare(FName(TEXT("HumanStudioAuto"))) == 0)
    {
        isOverlap = true;
        break;
    }
 
}
        
if (!isOverlap)
{
    FNavDataConfig HumanAgent(26.0f, 144.0f);
    HumanAgent.Name = FName(TEXT("HumanStudioAuto"));
 
    supportedAgents.Add(HumanAgent);
    NavSystem->OverrideSupportedAgents(supportedAgents);
 
    NavSystem->SaveConfig();
    NavSystem->SaveConfig(16384Ui64, *(FPaths::ProjectConfigDir().Append("DefaultEngine.ini")));
}
    
ANavMeshBoundsVolume *nmbv = NULL;
nmbv = Cast<ANavMeshBoundsVolume>(AddActorFromClass(ANavMeshBoundsVolume::StaticClass()));
NavSystem->OnNavigationBoundsAdded(nmbv);

 

GConfig 객체를 이용

GConfig->GetString(TEXT("/Script/NavigationSystem.NavigationSystemV1"),
        TEXT("SupportedAgents"),
        aaa,
        GEngineIni
    );
 
GConfig->SetString(TEXT("/Script/NavigationSystem.NavigationSystemV1"),
        TEXT("SupportedAgents"),
        TEXT("(Name=\"HumanStudio2\",Color=(B=0,G=255,R=140,A=164),DefaultQueryExtent=(X=50.000000,Y=50.000000,Z=250.000000),
        NavigationDataClassName=/Script/NavigationSystem.RecastNavMesh,AgentRadius=35.000000,AgentHeight=144.000000,
        AgentStepHeight=-1.000000,NavWalkingSearchHeightScale=0.500000,PreferredNavData=None,bCanCrouch=False,bCanJump=False,
        bCanWalk=True,bCanSwim=False,bCanFly=False)"),
        GEngineIni);
 
 
GConfig->Flush(false, GEngineIni);

INI File Matching

 

FConfigFile* ConfigFile = nullptr;
// Look for the first matching INI file entry
for (TMap<FString, FConfigFile>::TIterator It(*GConfig); It; ++It)
{
    if (It.Key().EndsWith(TEXT("DefaultEngine.ini")))
    {
        ConfigFile = &It.Value();
        break;
    }
}
check(ConfigFile != nullptr);
FConfigSection* Section = ConfigFile->Find(TEXT("/Script/NavigationSystem.NavigationSystemV1"));
if (Section != nullptr)
{
    TArray<FConfigValue> List;
    Section->MultiFind(TEXT("SupportedAgents"), List);
 
    for (auto& value : List)
    {
        UE_LOG(LogClass, Display, TEXT("TEST: %s"), *value.GetValue());
    }
 
}
