Stats-based actions

[SeeingStars]

Hello all, I feel like the solution is more obvious than what I'm making it out to be, but I'm at a mental block filtering through/implementing to no success similar codes.

So what I'm trying to design is a mechanic where performing certain actions cost certain stats (i.e. map navigation costs x stamina, interacting with an npc costs x stamina). In other words, there's an imagemap/navigation mode and and ADV/choice mode. I'm thinking this can be done within the block of code related to that particular stat change; however, I'm not sure on how to proceed. T.T...

Code: Select all

def sta_earn(self, amount):
            self.stamina+= amount
            if self.stamina< 0:
                self.stamina= 0
                "????" <--- Not sure what to do here 
            elif self.stamina> 100:
                self.stamina= 100

*I've thought about a renpy.jump ("label for being to tired"), but I'm not sure how to route it to jump back/handle every situation.
