Variable name of class

Development Programming & Scripting Blueprint

Hi.

I have a simple question.

Is it possible to have a variable in level blueprint with name of class? I need to get all actors from class which I am interacting with.

Thans in advance.

If you need “All Actor from Class” then there is a really nice function. It is called “Get All Actors from Class” and it returns an Array. You can then (if you haven’t created a variable(array) already) pull out the return array and chose “Promote to variable”. Then it will create a variable of the return type for you (:

Thank you for the answer, eXi :slight_smile:

  1. Click on object
  2. Get the class of clicked object
  3. Get all actor from that class

That is what I want to do in my level BP. I can’t doing this individually for each BP class, because with 5 and more classes there won’t be place for it :wink:

Is it possible to get that? Or maybe there is some better solution?

What do you mean there will not be the room?

I don’t understand.

I just want to doing this more automatically. I don’t want to have much work every time I add new blueprint class.

If I would do C++ scripting I suppose it would be possible to have a string variable (for the name of clicked class) which specifying class for further operations.

I don’t remember a way to just click a class and get its name.

The only way you could make this more efficiently is by making an array of classes and using a for each loop combined with the Get All Actors node and an Array of Arrays of Actors.

But i don’t see the needs.

Do you use blueprint classes of different baseclasses or are these “new” blueprint classes a child class of something? Because if you get the base/parent class with the “Get All Actors”, then you would also get the child classes if i’m not mistaken.

This way you could have x amount of different child classes, but still only use one Get All Actors Node for the base class.

You can see the details of what I want to do here, there are some screens also :slight_smile:

Hi, I wonder if it has as I can see the content of this page?

I need to make a code where I find all the variables of a class BluePrint …

if not, could you tell me a little more where research to develop this ??
