游戏控制的摄像机

了解如何激活和切换不同的视角。

定义引用的Actor

	UPROPERTY(EditAnywhere)
	AActor* CameraOne;

	UPROPERTY(EditAnywhere)
	AActor* CameraTwo;

	float TimeToNextCameraChange;

切换视角

#include "Kismet/GameplayStatics.h"

void ACameraDirector::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

	const float TimeBetweenCameraChanges = 2.0f;
	const float SmoothBlendTime = 0.75f;

	TimeToNextCameraChange -= DeltaTime;

	if (TimeToNextCameraChange <= 0.0f) {

		TimeToNextCameraChange += TimeBetweenCameraChanges;

		APlayerController* PlayController = UGameplayStatics::GetPlayerController(this, 0);
		if (PlayController) {

			if (PlayController->GetViewTarget() != CameraOne && CameraOne != nullptr) {
				PlayController->SetViewTarget(CameraOne);
			}
			else if (PlayController->GetViewTarget() != CameraTwo && CameraTwo != nullptr) {
				PlayController->SetViewTargetWithBlend(CameraTwo, SmoothBlendTime);
			}
		}
	}
}
