As in my example, to the player BP.
However, if you want something more advanced and proper, I’d move the whole thing to the Game Mode, perhaps even the player does not need to know about any of this:
- save game
- coin:
- game mode
The above translates to: whenever the player overlaps coins, we destroy the coin, increase a variable in the save game, and update the UI. The simpler it is now, the easier it will be to update later.
There is also the Game State and the Player State but if it’s single player, I would not bother.
Load the SG with the top score, and compare it to the current SG’s values.
Good luck!
