When Should I Use Direct References vs. Blueprint Interfaces in Blueprints?

[Rev0verDrive]

You can store a direct ref as a simple Actor (almost zero weight) then use BPI to get data.

If calling from an attached Component/Actor just use Get owning Actor, no need to store a ref.

Here’s a post that highlights BPI requests.

Find variable on object regardless of class

You can easily do this with Blue Print Interfaces (BPI). Create a BPI. Add a Function that outputs the data you want. [image] For each actor you want to get data from Add the Interface. [image] In the same actor double click on the interface function. This will open the function so you can add logic. [image] Drag your variables in and pipe them up. [image] Next open the Class that will Request the data (Character/Controller etc). Create a new MACRO. [image] [image] To use it si…
