Introduction
Introduced in Unreal Engine 4, Blueprints is a visual scripting language that is built into the engine. By using visual scripting, instead of writing code from scratch inside Visual Studio or some other IDE (which we will cover in the next chapter), we can use predefined actions and connect them together, similar to drawing a graph. This is often a great starting point for artists and game designers as it is much more visually oriented and easier to grasp than just plain code.
There are two types of blueprints you can create:
Level Blueprint: This works similarly to how UE3's Kismet system worked as events and actions that will occur in just this particular level. This is good for things such as triggering enemies to spawn or moving platforms.
Class Blueprints: Introduced in UE4, this can be put into any level. They just work using their predefined behavior that we create beforehand, similar to prefabs in Unity.
It may take some time to get used to it, but we will dive into some...
