Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

LNK2019/LNK2001

Hello, I am trying to do a simple "Trigger" for a PointLight, this is my first C++ Code, but it doesnt compile (Error LNK2019/LNK2001) . Anyone know a solution?

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

 #include "Trigger.h"
 #include "Components/PointLightComponent.h"
 
 
 // Sets default values
 ATrigger::ATrigger()
 {
      // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
     PrimaryActorTick.bCanEverTick = true;
     PointLight = CreateDefaultSubobject<UPointLightComponent>("Lighti");
 
 }
 
 // Called when the game starts or when spawned
 void ATrigger::BeginPlay()
 {
     Super::BeginPlay();
     PointLight->bVisible = true;
 
 }
 
 // Called every frame
 void ATrigger::Tick(float DeltaTime)
 {
     Super::Tick(DeltaTime);
 
 }
 
 

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

 #pragma once
 
 #include "CoreMinimal.h"
 #include "GameFramework/Actor.h"
 #include "Components/PointLightComponent.h"
 #include "Trigger.generated.h"
 
 UCLASS()
 class FORESTCP_API ATrigger : public AActor
 {
     GENERATED_BODY()
     
 public:    
     // Sets default values for this actor's properties
     ATrigger();
 
 protected:
     // Called when the game starts or when spawned
     virtual void BeginPlay() override;
 
 public:    
     // Called every frame
     virtual void Tick(float DeltaTime) override;
 
     UPROPERTY(VisibleAnywhere)
         UPointLightComponent* PointLight;
     
     UFUNCTION()
         void ToggleLight();
     
 };
