Implementing Local Split-Screen Multiplayer in Unreal Engine 5

Creating a local split-screen multiplayer game in Unreal Engine 5 (UE5) allows players to share a single screen while enjoying a game together. Here's a step-by-step guide to implementing this feature for the Nintendo Switch or PC platforms.

Step 1: Project Setup

Open Unreal Engine 5 and create or open your project. Ensure your game mode supports multiplayer and set the default number of players to more than 1 if needed.

Step 2: Configure Input

Configure input mappings for both players in Edit > Project Settings > Input to ensure separate controls for Player 1 and Player 2.

Step 3: Enable Split-Screen

Check Use Splitscreen in Edit > Project Settings > Engine - General Settings, and configure the Split-Screen Layout according to your game's requirements.

Step 4: Create a Blueprint for Split-Screen Logic

Use the Create Player node in your Level Blueprint to add a second player at game start, setting the Player Index to 1 and Spawn Pawn to true.

Step 5: Adjust Camera and Viewport

Adjust camera settings for split-screen play and ensure UI elements are displayed correctly for each player.

Step 6: Test Your Game

Test the game in the UE5 editor using Play in Editor (PIE) with multiple players to ensure everything works as expected.

Step 7: Deploy to Switch or PC

Follow platform-specific steps for deploying your project to the Nintendo Switch or PC.

Additional Tips:

• Optimize your game for performance to ensure smooth split-screen play.
• Regular playtesting is crucial to fine-tune gameplay balance and UI/UX design for split-screen.

This tutorial provides a foundational approach to implementing local split-screen multiplayer in UE5. Adapt these steps to fit your specific project needs.

Step 4: Detailed Blueprint Logic for Split-Screen Setup

4.1 Creating Player Characters

To add a second player in split-screen mode, you'll need to open your Level Blueprint and implement the following steps:

1. Right-click in the graph area and search for the Begin Play event node. This will be the starting point for our logic.
2. Drag from the Begin Play node and search for the Create Player node. Place this node and set the Player Index to 1 to indicate the second player.
3. Ensure the Spawn Pawn option on the Create Player node is checked. This will automatically create and possess a pawn for the second player.
4. To customize pawn spawning, connect additional logic to the Create Player node that specifies which pawn class to spawn and where.

4.2 Handling Player Input

Each player will need their own set of input controls. This is managed in the Project Settings:

1. Go to Edit > Project Settings > Input.
2. Create action and axis mappings for both players, ensuring they don't conflict and are appropriately mapped to different keys or controllers.

Step 5: Adjusting Cameras for Split-Screen

5.1 Camera Setup for Each Player

For split-screen play, each player's camera view can be adjusted individually:

1. In your pawn Blueprint, add a Camera Component if one isn't already present.
2. Use the Set View Target with Blend node in the Level Blueprint or Player Controller Blueprint, specifying each player's camera component.
3. Adjust camera settings such as Field of View (FOV) to ensure a good split-screen experience.

5.2 Configuring Split-Screen Views

Unreal Engine provides several settings to customize the split-screen experience:

1. Navigate to Edit > Project Settings > Engine - General Settings > Split Screen.
2. Here, you can adjust the split-screen mode (Horizontal or Vertical) and margins between screens.

Index of Required Scripts and Blueprints

• Level Blueprint: Contains the logic to initialize split-screen and spawn player characters.
• Player Pawn Blueprints: For each character type, ensure there's a Blueprint with properly configured input mappings and camera components.
• Player Controller Blueprint (Optional): If you're customizing control schemes or camera behavior further than what's provided by default.
• UI/HUD Blueprints: To create and manage UI elements that are specific to each player in split-screen mode.

This extended guide and index should help you implement local split-screen multiplayer in your Unreal Engine 5 project more effectively. Remember, the exact implementation details might vary based on your project's specific needs and setup.
