So, things like references to meshes or other components, or variables YouĬan use them to help perform what the function needs to, but they get tossed away after the function has completed.Ĭlass variables are for things that you are potentially going to be interested in accessing from multiple places in the Blueprint. You can consider local variables a 'scratch pad' to work with in a function. This helps to reduce clutter for things that are only relevant within the context of that function. So, a local variable in a function is only visible to that function, and not to other functions, or theĮvent Graph. Local variables are scoped, which means that they only exist where you define them. When you're inside a function though, you'll see an additional section of the My Blueprint tab for Local Variables. When you're working in your Blueprint, you have the ability to add variables using the My Blueprint

Operate on Actors (say, calling Set Brightness on a light), and paste them into a Blueprint Class based off of a Light Actor, the functions will update to be in the proper scope. When you copy functions from a Level Blueprint that If you do start out in the Level Blueprint, and then decide to move behavior into a Blueprint Class, this should be a pretty simple process. Many copies as you would like to the level, without needing to copy script around. If you create a Blueprint Class, you can add it to any of your levels, and you can also add as In general, Blueprint Classes are the best way to get reusable behavior in your project. Some examples would be kicking off a cinematic when a certain trigger is touched, or opening a particular door after you kill all the enemies.

This does mean that Level Blueprints can be great places to set up functionality specific Getting familiar with the Blueprints system, but they are specific to the level that they're used in. They're great for one-off prototypes, and Level Blueprints may be very familiar to users of UE3's Kismet, because you can select objects directly in the level, and operate on them. Over some of the more common decisions you will have to make, as well as tips and tricks for Blueprint users. If you would like to read more about coding for Blueprints, or the technical details of Blueprint compiling, see the Blueprints Technical Guide.Įven if your functionality is well-suited for Blueprints, there are decisions you can make in setting up your Blueprints that will make things go more smoothly. Blueprints are best suited to making event-driven functionality, such as handling damage taking, controls, and other things that don't get called every frame. If you have a Blueprint that's doing a lot of operations and complex math every tick, you might want to consider using However, there are certain things that will impact your performance more if they are done in Blueprints. Is possible with the Blueprint visual scripting system. Everything from making a small game or procedural content tools, to prototyping new functionality, to tweaking and polishing things made by programmers,
