在Unreal中实现相机的震动

有时候需要画面更加具有冲击力，或者需要更强的打击感，使相机进行震动是不错的方案。

Unreal 笔记

ULegacyCameraShake

在Unreal中实现了摄像机的震动，只需要继承ULegacyCameraShake类即可实现。

创建CameraShake类。
初始化该类的信息，包括相机震动的幅度，持续时间等等。

// CameraShake.cpp
UCameraShake::UCameraShake()
{
    // 持续时间
    OscillationDuration = 0.1f;
    // 渐入时间
    OscillationBlendInTime = 0.02f;
    // 渐出时间
    OscillationBlendOutTime = 0.02f;

    // 振幅与频率
    LocOscillation.X.Amplitude = 5.0f;
    LocOscillation.X.Frequency = 5.0f;

    LocOscillation.Y.Amplitude = 5.0f;
    LocOscillation.Y.Frequency = 5.0f;

    LocOscillation.Z.Amplitude = 5.0f;
    LocOscillation.Z.Frequency = 5.0f;

    RotOscillation.Pitch.Amplitude = 0.0f;
    RotOscillation.Pitch.Frequency = 0.0f;

    RotOscillation.Yaw.Amplitude = 0.0f;
    RotOscillation.Yaw.Frequency = 0.0f;

    RotOscillation.Roll.Amplitude = 0.0f;
    RotOscillation.Roll.Frequency = 0.0f;
}

触发相机的震动

编写出发相机震动的函数，在需要触发震动时，调用该函数即可。

void ABasePawn::TriggerCameraShake()
{
    APlayerController* PlayerController = UGameplayStatics::GetPlayerController(this, 0);
    if (PlayerController && PlayerController->PlayerCameraManager)
    {
        PlayerController->PlayerCameraManager->StartCameraShake(UCameraShake::StaticClass());
    }
}
