Unreal Engine’s casting system supports casting from one interface to another, or from an interface to an Unreal type where appropriate. The following examples are some methods that you can use to cast interfaces:

Blueprints that declare functions to define an interface between Blueprints. A Blueprint Interface is a collection of one or more functions - name only, no implementation - that can be added to other Blueprints. Any Blueprint that has the Interface added is guaranteed to have those functions.

In this Quick Start guide, you will learn how to use Interfaces by creating a simple interaction system to communicate with two different Actors. Create an Interface with an Interact function. Create interactive lamp and door Actors and implement the interface.

Dec 4, 2024 · In this post, we'll create an interaction system for our Unreal Project, we'll be using Blueprint Interfaces to create a higher level abstraction between objects. What are Blueprint interfaces? A Blueprint Interface is a collection of one or more functions - name only, no implementation - that can be added to other Blueprints.

Sep 29, 2020 · Interfaces are a C thing. They’re a set of functions that one class can implement so that an action is performed on another class of a potentially different type. Rather than calling a function explicitly on another class, we’re sending a message.

Jan 8, 2024 · An interface in Unreal Engine is a blueprintable system that allows different classes (like actors and components) to communicate with each other in a flexible way. Think of it as a contract or...
