Hi, you can change the backstory and other properties by using the `Update Character` function, you can find all the related info in the following documentation

I don’t need to call any update function after that right?  
Like when I change backstory in the site I’ll have to click update.  
But when using update character node, I won’t need to call an update function it’ll just do it automatically?

\<@365628745886859267\> is there a way to control state of mind in the engine?  
I’ve set up a character that get’s angry if she doesn’t get what she wants.  
it works in the side but in the engine she’s passive
