Fix recursive gambling issue causing multiple "Go Back" selections - resolves #22

[Copilot]

Problem

Players were required to select "Go Back" multiple times when exiting the gambling feature after changing their bet. This occurred because the changeBet() method in the tavern was calling gamble() recursively, creating nested gambling loops.

Root Cause

In src/location/tavern.py, the gambling flow worked as follows:

1. Player chooses "Gamble" from tavern menu
2. Player chooses "Change Bet"
3. changeBet() method processes the bet amount
4. Problem: changeBet() calls self.gamble() recursively
5. This creates a nested gambling loop inside the original gambling loop
6. When the player wants to exit, they must press "Back" once for each nested level

Solution

Primary Fix: Removed the recursive self.gamble() call from the changeBet() method. Instead of creating nested loops, the method now simply sets the bet amount and updates the prompt, then returns control to the main gambling loop.

Before:

def changeBet(self, prompt):
    # ... input handling ...
    if self.amount <= self.player.money:
        self.currentBet = self.amount
        self.currentPrompt.text = f"What will the dice land on? Current Bet: ${self.currentBet}"
        self.gamble()  # ❌ Recursive call creates nested loops

After:

def changeBet(self, prompt):
    # ... input handling ...
    if self.amount <= self.player.money:
        self.currentBet = self.amount
        self.currentPrompt.text = f"What will the dice land on? Current Bet: ${self.currentBet}"
        # ✅ Return to main loop instead of recursing

Additional Fix: Corrected invalid error handling that was calling a non-existent self.deposit() method, replacing it with proper prompt updates.

Testing

• All 57 existing tests continue to pass
• Added new test test_changeBet_no_recursive_gamble to verify the fix
• Manual testing confirms players now only need one "Back" selection to exit gambling
• Error handling verified for invalid input and insufficient funds

Impact

• User Experience: Players can now exit gambling with a single "Back" selection as expected
• Code Quality: Eliminated problematic recursion pattern while maintaining all functionality
• Compatibility: No breaking changes - all existing behavior preserved except for the bug fix
