Unable to access Blueprint variables in my HUD Blueprint

[Carcer_Dun]

Hi folks,

As you can tell from the question above I am trying to hand values through from one of my blueprints to another. I am trying to hand variable values through from an actor class through into a HUD Blueprint.

My initial tactic for this was to set up a reference for the Actor class within the HUD Blueprint so I could call on the values. This however did not work at all. I then tried setting up an interface allowing them to talk to each other but this still did not work. Finally I thought I could hand in the values through another connected Blueprint that was actually sharing information but this still did not work.

I have included screen shots of the Blueprints that were not working. I merely need access to these so I can calculate the damage for various enemies and so I can update a progress bar with a dwindling health pool.

Any help will be much appreciated,

Image 3: The HUD Blueprint with reference to the actor I want access too(I did make it public but this was having to go back to show what I did)

Image 4: HUD Blueprint with reference to actor after it has been moved into the PlayerCharacter which I can access

With the PlayerCharacter I am already doing that and it was having no effect.
With the original Actor(enemyBP) it was impossible to do that, so it didn’t work.
Thank you though.

You could try casting ?

Casting Quick Start Guide

Basically if you cast using your player character you can access any variable you want from your hud.

Mine is a template so its using defualt FirstPersonCharacter, you should cast to your character class then off As First Person Character you can get or set any Var

Hope this helps

Sorry i couldn’t be of more help with your enemytohudBP function you could try adding input and output variables, then setting a variable through the enemyBP then accessing it using the function on your HUD.

Or failing that use a blueprint interface then refrence it in the class settings of the widget and EnemyBP
