1. Begin by creating a New > Games > Third Person > C++ project named StaticCameras.

2. Launch the C++ Class Wizard, enable the checkbox for Show All Classes, then type CameraActor within the search field to select and create your new Camera Actor class named ExampleCameraActor.

   

3. From the C++ Class panel, right click on your ExampleCamera and from the dropdown C++ Class actions menu select Create a Blueprint class based on ExampleCameraActor. Then drag an instance of BP_ExampleCameraActor into the level.

   

1. Using the C++ Class Wizard, create a new Actor class named BlendTriggerVolume.

   

2. Navigate to your BlendTriggerVolume.h file, and declare the following code in your class definition.

   C++

   protected:
   		
            //Collision Bounds of the Actor Volume
            UPROPERTY(EditAnywhere, BlueprintReadWrite)
                class UBoxComponent* OverlapVolume;
   		
                //Camera Actor which the Actor Volume blends to
                UPROPERTY(EditAnywhere, BlueprintReadWrite)
                TSubclassOf<ACameraActor> CameraToFind;
   		
   
   Expand code Copy full snippet(18 lines long)

3. Next, navigate to your BlendTriggerVolume.cpp file to set up your constructor and box component overlap methods. Declare the following include class libraries.

   C++

   `#include "Components/BoxComponent.h"`
   		
            `#include "StaticCamerasCharacter.h"`
   		
            `#include "Camera/CameraActor.h"`
   		
            `#include "Runtime/Engine/Classes/Kismet/GameplayStatics.h"`

   Copy full snippet(7 lines long)

4. In the constructor ABlendTriggerVolume::ABlendTriggerVolume, declare the following code.

   C++

   ABlendTriggerVolume::ABlendTriggerVolume()
            {
            //Create box component default components
            OverlapVolume = CreateDefaultSubobject<UBoxComponent>(TEXT("CameraProximityVolume"));
            //Set the box component attachment to the root component.
            OverlapVolume->SetupAttachment(RootComponent);
            }

   Copy full snippet(7 lines long)

5. Next, implement your NotifyActorBeginOverlap and NotifyActorEndOverlap class methods:

   C++

   void ABlendTriggerVolume::NotifyActorBeginOverlap(AActor* OtherActor){
            //Cast check to see if overlapped Actor is Third Person Player Character
   		
            if (AStaticCamerasCharacter* PlayerCharacterCheck = Cast<AStaticCamerasCharacter>(OtherActor))
                {
   		
            //Cast to Player Character's PlayerController
   		
            if (APlayerController* PlayerCharacterController = Cast<APlayerController>(PlayerCharacterCheck->GetController()))
                    {
   
   Expand code Copy full snippet(35 lines long)

6. Compile your code.

	{

Setting up the Overlap Trigger Actor

Now that you have created your overlap Actor, you will need to place it into the level and set up its bounds.

1. Begin by navigating to your C++ Classes folder, right-click on your BlendTriggerVolume class, select Create Blueprint Class based on BlendTriggerVolume, then name your Blueprint Actor BP_BlendTriggerVolume.

   

2. From the class defaults, navigate to Camera To Find in the Details panel, open the drop down menu, then select BP_ExampleCameraActor.

   

3. Optionally, you can change the default blend time for this Blueprint without having to go back into the source code, or affecting other Blueprints with the same inherited parent class.

   

4. Compile and Save.

   

5. From the Content Browser, drag an instance of BP_BlendTriggerVolume into the level.

   

6. Move the BP_BlendTriggerVolume into the room with your BP_ExampleCameraActor, and from the Details panel select the box component. Navigate to the Shape category and modify the Box Extent X, Y, and Z values so the volume will fit your room.

   

7. From the Main Editor View, click the Play button to play in the Editor.
