Now multiplayer-wise, game framework Objects, and more specifically Actors, can behave differently over the network. Regardless of networking, understanding Unreal’s Gameplay Framework, will not only make your code well-structured, but also keep you from reinventing the wheel, which will save you precious time down the line. Get to Know the Game Framework Objects Online-wise However, they proved useful over the course of my experience with networking code in Unreal Engine. In this post I try to consolidate all the tips and tricks I’ve gathered while revamping my humble networking experience.īy no means these are rules that you will be judged for if you choose not to comply with. The Function name matches the name of the Function you named earlier in this guide.Unreal Engine Multiplayer Tips and TricksĪs you keep practicing online multiplayer in Unreal Engine, you might have already wondered what are the best practices to tackle a specific issue, or even ranted about your code not behaving the way you desired.

Open your Level Sequence, then create an Event Track by clicking Add Track (+) > Event Track > Trigger. Now that the Level Blueprint side of the logic is set up, you can implement the rest of the logic in Sequencer's Event Track. In this example, the logic is activating a Niagara System. Due to the arbitrary nature of Blueprints, this guide will assume your Level Blueprint logic is already created. Add the Event and connect it to the Level Blueprint logic you want to trigger. The event name matches the name of the Function you named earlier in this guide. Right-click in the Event Graph and add the Event from your Blueprint Interface.

You have an understanding of how to create and use the Event Track. You have a basic understanding of how to create and open a Level Sequence. This document provides instructions on how to trigger Level Blueprint events from Sequencer's Event Track. You can do this using Blueprint Interfaces and additional set-up steps in the Director Blueprint. In your project, there may be cases where you instead want events from Sequencer to trigger in other Blueprints, such as the Level Blueprint. Event Tracks are mainly used to trigger Blueprint Scripts within Sequencer's Director Blueprint.
