In Unreal, blueprints use nodes connected to each other. These nodes can be events (i.e. whenever you press the space bar), actions (i.e. move the player here), conditions (i.e. is this equal to this?), etc. Nodes can also have inputs and outputs.

A Blueprint Class, often shortened as Blueprint, is an asset that allows content creators to easily add functionality on top of existing gameplay classes. Blueprints are created inside of Unreal Editor visually, instead of by typing code, and saved as assets in a content package.

The Blueprint 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. As with many common scripting languages, it is used to define object-oriented (OO) classes or objects in the engine.

With these functions and events, you can even communicate and pass data between other Blueprint Actors. Blueprint isn't its own language distinct from C++; it runs on a virtual machine layer?a separate process that translates Blueprint into C++. This means that Blueprint Actors may require extra processing power.

Blueprints were first introduced in Unreal Engine 4 and the short explanation is that Blueprints are a way to create a UCLASS without the need to actually write C++ code. When you create a new blueprint in the editor, you will have to extend it from some other class, that being a native C++ class or another blueprint.

Converting From Blueprints to C++ Since Blueprints are easier to create and iterate on, it is common to build prototypes in Blueprint and then move some or all of that functionality into C++.

Blueprint is a high level, visual scripting system that provides an intuitive, node-based interface that can be used to create any type of script events in the Unreal editor.

A Software Blueprint provides you with a solid plan outlining exactly what features your custom software should include, what users your custom software will be servicing, what it should look like, how it will function and how it will be built.
