How can I reset the camera settings to default during gameplay in Unreal Engine?

Resetting Camera Settings to Default in Unreal Engine

Resetting camera settings to default during gameplay in Unreal Engine requires a mix of blueprint scripting and configuring default camera components. Here’s a step-by-step guide:

1. Utilize Blueprints

The most straightforward approach is to use Blueprints, Unreal Engine’s visual scripting system, to reset the camera:

Games are waiting for you!

• Create a New Blueprint: Start by creating a new Blueprint based on the PlayerController to handle inputs specifically for resetting the camera.
• Add Input Handling: Open the Blueprint’s Event Graph, and set up an event to listen for a key press or a button click.
• Reset Camera: Use the Set View Target with Blend node to switch the current camera view to the default camera, which you have pre-configured in the scene.

2. Configure Default Camera Settings

• Predefine Default Values: Ensure that you have predefined values for your camera’s transform, rotation, and field of view.
• Store Default Settings: You can store these settings in a struct or as variables within your game instance to be referenced during the reset operation.

3. Code-Based Reset (Optional)

If you’re using C++ in your project, you can reset the camera directly through code:

void AYourPlayerController::ResetCameraToDefault() { 
    FVector DefaultLocation = FVector(0.0f, 0.0f, 300.0f); 
    FRotator DefaultRotation = FRotator(-45.0f, 0.0f, 0.0f); 
    float DefaultFOV = 90.0f; 
    
    // Assuming 'CameraComponent' is your default camera
    CameraComponent->SetWorldLocationAndRotation(DefaultLocation, DefaultRotation);
    CameraComponent->FieldOfView = DefaultFOV;
}

Compile and run your project, ensuring that your input bindings for resetting the camera call this method.

4. Testing

Once the scripting and configurations are complete, thoroughly test in various game states to ensure the camera consistently resets to its default settings without causing glitches or interruptions to gameplay.
