Node: Update Ammo Text Graph: Shoot Function Function: Shoot Function Blueprint: BP_FirstPersonCharacter i need help to solve this isue this is my first person character blueprint
After you create the widget, you need to store it in the MainHudRef Variable.
eg:
Here I’m using one called Main overlay, but is the same in your case, just replace with with MainHudRef
Is kinda hard to see with the small images, but it seems you’re creating a new main hud every time you shoot?
Just access the variable, the hud should already be created just one time at the start.
thank you for the answer i still have a question though how would i access the variable in here instead of creating a new Main hud
Just drop in the “get” node from the variable where you stored the widget in.
From there you can call anything on the widget class.
eg:
I’d recommend you follow through this learning resource: Blueprint Communication | Course
it goes over all the ways in which you can send info between blueprints.
