Blueprints scripting overview
The Blueprints Visual Scripting system in Unreal Engine is a complete gameplay scripting system based on the concept of using a node-based interface to create gameplay elements from within Unreal Editor.
This system is extremely flexible and powerful as it provides the ability for designers to use virtually the full range of concepts and tools generally only available to programmers.
In addition, Blueprint-specific markup available in Unreal Engine's C++ implementation enables programmers to create baseline systems that can be extended by designers.
Concepts related to Unreal Blueprint Templates and development using them.
In their basic form, Blueprints are visually scripted additions to your game. By connecting Nodes, Events, Functions, and Variables with Wires, it is possible to create complex gameplay elements.
Blueprints work by using graphs of Nodes for various purposes - object construction, individual functions, and general gameplay events - that are specific to each instance of the Blueprint in order to implement behavior and other functionality.
Let's look at each of these use cases by an example.
