How to add variables from diffrent blueprints

Development Programming & Scripting Blueprint

So I’ve got a money variable in one blueprint called “Character1” then I’ve got another blueprint called “coin” that adds to the “money” variable. But I can’t figure out how to add them.

I’m using 4.8.1

Thanks

It’s not a good idea to have a Coin blueprint for storing the amount of coins the player has since there are probably multiple coins, you should probably do that in the character blueprint.

You’ll need to get a reference to the other blueprint and access it’s money variable.

If you’re not sure how to do this:

  1. If it’s an actor component on the same actor - get owner -> Get actor component by class, or cast to the proper actor type and get the other component
  2. If it’s another actor, you can either store a reference to it from within the editor or use the Get All Actors by class node and find it

Edit: That being said, (depending on the uses of coin) I would recommend making it an actor component or placing the logic directly into the character (as suggested by Jamendxman3)

The “coin” blueprint is a ACTOR blueprint not just a blank blueprint holding a variable. And still not getting how to set the value of the money vaiable.

Just increment a coin variable in your player once you collide with a coin, and then cast to the coin and call Destroy Actor.
