Concepts related to Unreal Blueprint Templates and development using them.
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.
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.
C++ is always faster. Blueprints use Virtual Machine(VM) to translate functionality to C++.
If you have a Blueprint that's doing a lot of operations and complex math every tick(frame rendered), you might want to consider using native C++ functions instead.
Blueprints are a set of functionality that is made available to you in the visual editor. You can write anything that is not available to you as Blueprints, using C++.
Blueprints use object references, it is possible to have a circular dependency in your blueprint code.
