Replicating Destroying Actors in Unreal Engine for Multiplayer Games

In today's tutorial, we will delve into another episode of replication in Unreal Engine. This time, our focus will be on replicating the process of destroying actors, or more simply, picking up items. We will ensure that this functionality works seamlessly for both the server and the client, allowing for a synchronized experience for all players involved.

Overview of the Tutorial

Let's start by visualizing what we aim to achieve. In the demonstration, there are five boxes present that can be picked up and destroyed by both the server and the client. When a client interacts with an object, it gets destroyed for all players in the game, maintaining consistency across the multiplayer environment.

Setting Up the Blueprint

1. Setting Up Custom Events

To initiate this replication process, we first need to work within the character blueprint. Here's a step-by-step guide:

Inside the character blueprint, add a custom event named "Destroy Actor on Server." Ensure this event is set to run on the server by selecting the Replicates option and choosing Run on Server.
Add another custom event named "Destroy Actor on Client." This event should be set to multicast to run on all clients.
Implement an Is Valid check to avoid potential errors in case of simultaneous destruction attempts from both the server and clients.
Connect the necessary nodes to set up the interaction between the server and client events.

2. Implementing the Interaction

Incorporate an interaction system, preferably using blueprint interfaces for efficiency in multiplayer scenarios. This system will handle the interaction logic between the character blueprint and the objects to be destroyed.

Implement the interact function within the interface.
Ensure the blueprint of the object to be destroyed incorporates the implemented interface.
Call the "Destroy Actor on Server" custom event from the interact function, passing the object reference to initiate the destruction process.

Testing the Replication

After setting up the blueprint interactions, test the replication functionality by interacting with the designated objects. Verify that the destruction process occurs seamlessly for both the server and the clients, providing a consistent gameplay experience.

By following these steps, you can replicate the destruction of actors efficiently in a multiplayer environment, ensuring synchronized gameplay across all connected clients.

Conclusion

In conclusion, we have successfully implemented a replication system for destroying actors in Unreal Engine, suitable for multiplayer games. Whether it's about picking up items, eliminating enemies, or interacting with in-game elements, this method ensures a synchronized experience for all players involved.
