Is it possible to somehow get the variable value form blueprint to c++ variable? I don’t need to change it in blueprint via c++, only get the value.
Hey DrewDebelo,
Its possible but you need to create a C++ class with a UPROPERTY( BlueprintReadWrite ) variable and then create a Blueprint class from that C++ class.
Then, from the Blueprint, assign that variable and then in the code for C++ you can use it. I usually do something like this when I need a reference to the root UCanvasPanel for UserWidgets.
And if i already have the blueprint class and variables?
Does the Blueprint class extend a C++ class?
No, i have a character c++ class, and have a blueprint class, and this blueprint class has a variable which i need to read in c++ character class. As i can guess this is not possible, unless i make a blueprint extension for c++ character and cast from the blueprint with variable to this extension to get this variable and use it. Well actually i have already had all this stuff working using only blueprints, but now there is a necessity to recreate character, ai and everything related to it in c++, but blueprint where the needed variable sets is something i won’t be able to reproduce in c++ (it’s from marketplace and i’m only getting started with c++), so…i stuck here
Hope this mess of words is possible to understand.
Thanks.
What is the Blueprint class that you are using? You can still make a C++ class for it and just copy the Blueprint already done into the new Blueprint class coming from the C++ class you’ve made.
Is it possible to make an empty character c++ class, AIController c++ class, make al the AI stuff in c++ then inherit a blueprint from this class and set up everything else?
Yeah. That is generally the work flow, to do the bulk of the classes logic in C++ then setup what you want (such as SkeletalMeshComponents, Particle Systems, and Sounds) in the Blueprint class.

Hey, I am having the same issue as the original poster. I understand the workflow but I do not know how to write the code, I just need to get a mesh and material from the blueprint to use in the c++ class, How would I go about that?
