Blueprints in Unreal Engine are a visual scripting system that allows developers to create gameplay elements without the need to write code. They are an integral part of the engine and provide a user-friendly means of controlling the game logic.
At its core, a Blueprint is a node-based interface where each node represents a function or value, which can be connected to other nodes to form complex behaviors. There are several types of Blueprints:
Example uses of Blueprints:
Here's a simple example of spawning an actor using Blueprints:
By connecting nodes for inputs, outputs, and various operations, developers can build complex logic visually. Since its introduction, Blueprints have become a key feature for rapid prototyping and development within Unreal Engine, allowing teams with less programming experience to contribute significantly to the game development process.
