What do you mean updated/changed? Like the player’s state or something?

You can store an extra version of the variable you want to track and then constantly check if it’s still equal to the one that’s changing. If it’s ever not equal, you know the tracked variable has changed, so you run the code you want to run and then make sure to set the tracker variable to the tracked variable at the end.
