How can I create a Sub-Object Property in my custom UActorComponent class, to access from Blueprint?

Hi everyone,

I have a class StatsController, where I’m storing my character’s _health:

class UStatsController : public UActorComponent

	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = HUD)
	int32 _health;

In my HUD EventGraph, I’m doing the following:

Event Contstruct    -> 
Get Player Character -> Cast To MyACharacter

In my HUD HealthProgressBar, I’m able to see the Stats Controller, but there are no available Sub-Object Properties to bind to.

How can I enable my _health (or even a float _percentHealth) to be a bind point in the HUD blueprint?

You need to make the member variable visible and editable in blueprints, here are the parameters explained:

most commonly though:
(inside your component .h)

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = whateveryouwant)
membervariabletype membervariablename;

in the object constructor, initialize it:

membervariablename = blah;

Then in the HUD, drag off the cast of the AMyCharacter and search for the member variable name.
