Hi, I have a question about routeplanner, here i want to create massive of routeplanners in editor, with massive of coordination points data which for the locations of triggervolume , splinepoints and so on , is there any loluntion that i can automatically genrate these routeplanners ?
thanks.

Here is what I doing, I just personal modified the routplanner file to give them a fixed location and route and write a python scripts to generate massive of cpp and h just changing location data in every cpp and h file, just like this

`#include "Carla.h"

include "MyRoutPlanner0.h"

include "Util/RandomEngine.h"

include "Vehicle/CarlaWheeledVehicle.h"

include "Vehicle/WheeledVehicleAIController.h"

include "Engine/CollisionProfile.h"

static AWheeledVehicleAIController GetVehicleController10 (AActor Actor) { auto *Vehicle = (Actor->IsPendingKill() ? nullptr : Cast(Actor)); return (Vehicle != nullptr ? Cast(Vehicle->GetController()) : nullptr); }

static const USplineComponent PickARoute10 ( URandomEngine &RandomEngine, const TArray<USplineComponent > &Routes, const TArray &Probabilities) { check(Routes.Num() > 0);

auto Index = RandomEngine.GetIntWithWeight(Probabilities); check((Index >= 0) && (Index < Routes.Num())); return Routes[Index]; }

// Sets default values AMyRoutPlanner0 :: AMyRoutPlanner0 (const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer) { RootComponent = ObjectInitializer.CreateDefaultSubobject(this, TEXT("SceneRootComponent")); RootComponent->SetMobility(EComponentMobility::Static); TriggerVolume0 = CreateDefaultSubobject(TEXT("TriggerVolume0")); TriggerVolume0->SetupAttachment(RootComponent); TriggerVolume0->SetHiddenInGame(true); TriggerVolume0->SetMobility(EComponentMobility::Static); TriggerVolume0->SetCollisionProfileName(FName("OverlapAll")); TriggerVolume0->bGenerateOverlapEvents = true; TriggerVolume0->SetBoxExtent(FVector(200, 200, 200),false); TriggerVolume0->SetWorldLocation(FVector(96447.39179266617, 57826.342385751195, 124.28526651032428)); TriggerVolume0->SetWorldRotation(FRotator(0, 357, 0));

RouteDirection0 = CreateDefaultSubobject(TEXT("RouteDirection0")); RouteDirection0->SetupAttachment(RootComponent); RouteDirection0->SetHiddenInGame(true); RouteDirection0->SetMobility(EComponentMobility::Static); RouteDirection0->RegisterComponent(); RouteDirection0->SetWorldLocationAtSplinePoint(0,FVector(96447.39179266617, 57826.342385751195, 124.28526651032428)); RouteDirection0->SetWorldLocationAtSplinePoint(1,FVector(96450.87560461834, 57749.46527731372, 124.05791036702851)); RouteDirection0->AddSplineWorldPoint(FVector(96641.5511756204, 53731.94724371424, 111.406857482271)); Routes.Add(RouteDirection0);

}

if WITH_EDITOR

void AMyRoutPlanner0 ::PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent) {

Super::PostEditChangeProperty(PropertyChangedEvent); const auto Size = Routes.Num(); if (PropertyChangedEvent.Property && (Size != Probabilities.Num())) { Probabilities.Reset(Size); for (auto i = 0; i < Size; ++i) { Probabilities.Add(1.0f / static_cast(Size)); } } }

endif

// Called when the game starts or when spawned void AMyRoutPlanner0 ::BeginPlay() { Super::BeginPlay(); if (!TriggerVolume0->OnComponentBeginOverlap.IsAlreadyBound(this, &AMyRoutPlanner0::OnTriggerBeginOverlap)) { TriggerVolume0->OnComponentBeginOverlap.AddDynamic(this, &AMyRoutPlanner0::OnTriggerBeginOverlap); }

}

void AMyRoutPlanner0::EndPlay(const EEndPlayReason::Type EndPlayReason) { //Endplay Insert Tag, don't delete! if (TriggerVolume0->OnComponentBeginOverlap.IsAlreadyBound(this, &AMyRoutPlanner0::OnTriggerBeginOverlap)) { TriggerVolume0->OnComponentBeginOverlap.RemoveDynamic(this, &AMyRoutPlanner0::OnTriggerBeginOverlap); }

}

TArray<FVector> WayPoints;
const auto Size = Route->GetNumberOfSplinePoints();
check(Size > 1);
WayPoints.Reserve(Size);
for (auto i = 1; i < Size; ++i)
{
  WayPoints.Add(Route->GetLocationAtSplinePoint(i, ESplineCoordinateSpace::World));
}

Controller->SetFixedRoute(WayPoints);

} } `

and the H files:

`#pragma once

}; `

because the size of the map ,I generated 800 cpp and h files, when I want to rebuild, I always get error about
