Study Notes

Unreal Engine's Visual Scripting System

Unreal Engine's Blueprint Visual Scripting system is a complete gameplay scripting system based on a node-based interface.
Blueprints use nodes,events, functions, and variables connected with wires to create complex gameplay.
Blueprints use graphs of nodes to implement behavior and functionality.

Common Blueprint Types

Level Blueprints: Associated with individual levels, they manipulate actors, manage cinematics, control level streaming, and interact with Blueprint Classes.
Blueprint Classes: Used to create interactive assets like doors, switches, and collectible items. They respond to player events, animate, and play sound effects.

Construction Scripts

Construction Scripts within Blueprint Classes execute when an actor is placed or updated, enabling faster creation of customizable props.

Blueprint Script

Blueprint script is similar to Blueprint Classes and can create a game's HUD.

Blueprint Editor

Blueprint Editors offer a graph mode for laying out the network of a Blueprint.

Blueprint Elements

Variables: Data types like Boolean, integer, and float are color-coded for easy identification.
Reference Types: Hold objects, actors, and classes.

Blueprint Execution

Events are executed using a white execution wire, and data flows through colored wires matching variable types.
Input pins evaluate output pins, while pure nodes reevaluate outputs when connected.

Blueprint Flexibility

Blueprint provides designers with a range of scripting tools typically available to programmers.
C++ programmers can create baseline systems that designers can extend using Blueprints.

Types of Blueprints

Data-Only Blueprint: Contains only code, variables, and components inherited from its parent.
Blueprint Interface: A collection of functions that can be added to other blueprints, ensuring consistent functionality.
