I’m having a really annoying issue with a -supposedly- very simple task that I just cannot find an answer for.
I have 2 blueprints; A character blueprint, and a HUD blueprint.
Within the HUD blueprint there is a boole variable that I want to access from the character blueprint.
Just for ease of example, say that if I press the “O” key (or any other key or event used to trigger) I want the boole variable within the HUD blueprint to become 1. So I create a reference variable within the character blueprint that refers to the HUD blueprint. Then give that variable a tooltip and make it public. Also the variable within the HUD blueprint is set to public.
No matter what I do, it never works. I always get the “Accessed None ‘HUD’ from node etc. etc.” error. This goes for any blueprint I create every time it wants to access a variable from another blueprint. Could someone show me how to do this?
I’ve already seen Direct Actor Communication Quick Start Guide | Unreal Engine Documentation but unfortunately it gives no help.
