⚔️ Battle System Stuck - Need Debugging Help!

Hey everyone! I’m working on an RPG project and running into a frustrating issue with my battle system. Here’s what’s happening:

  • Sometimes when players press battle move buttons, nothing happens
  • The game gets stuck in an endless battle state
  • Players just see the enemy sprite but can’t progress
  • The battle doesn’t transition to the next phase

I suspect the issue is in either the button sprites or enemy sprites, but I’ve been debugging for hours with no luck. The battle system works sometimes but fails randomly. 😤

Has anyone dealt with similar battle system state management issues?

@RPGDeveloper_Alex I’ve seen this exact issue many times! It’s usually a state management problem. Let me walk you through the most common causes and solutions:

🔍 Battle System State Flow

Here’s how a proper battle system should flow:

flowchart TD A[🎮 Battle Start] --> B[Set Battle State = 'active'] B --> C[Show Battle UI] C --> D[Wait for Player Input] D --> E{Button Pressed?} E -->|Yes| F[Process Move] E -->|No| D F --> G[Calculate Damage] G --> H[Update Health] H --> I{Enemy Defeated?} I -->|Yes| J[Set Battle State = 'victory'] I -->|No| K[Enemy Turn] K --> L[Enemy Attack] L --> M{Player Defeated?} M -->|Yes| N[Set Battle State = 'defeat'] M -->|No| D J --> O[🏆 Victory Screen] N --> P[💀 Game Over] style A fill:#e1f5fe style B fill:#f3e5f5 style J fill:#e8f5e8 style N fill:#ffebee

🐛 Common Issues & Solutions

1. Missing State Reset

Make sure you reset battle state properly:

    when flag clicked
set [battle state v] to [none]
set [player turn v] to [true]
set [button pressed v] to [false]

2. Button Response Issues

For your battle buttons, use this pattern:

    when this sprite clicked
if <(battle state) = [active]> then
if <(player turn) = [true]> then
set [button pressed v] to [true]
set [selected move v] to [attack]
broadcast [process move v]
end
end

3. State Management in Main Battle Loop

    when I receive [start battle v]
set [battle state v] to [active]
set [player turn v] to [true]
repeat until <(battle state) = [ended]>
if <(player turn) = [true]> then
wait until <(button pressed) = [true]>
// Process player move
set [button pressed v] to [false]
set [player turn v] to [false]
else
// Enemy turn logic
wait [1] seconds
// Process enemy move
set [player turn v] to [true]
end
// Check win/lose conditions
if <(player health) < [1]> then
set [battle state v] to [ended]
broadcast [battle lost v]
end
if <(enemy health) < [1]> then
set [battle state v] to [ended]
broadcast [battle won v]
end
end

🔧 Debugging Tips

  • Add debug displays: Show current battle state, turn status, and button states on screen
  • Use broadcasts: Instead of direct variable changes, use broadcast messages for state transitions
  • Check timing: Make sure there are no infinite loops or missing wait blocks
  • Test edge cases: What happens if buttons are clicked rapidly or during enemy turns?
    // Debug display (add to stage)
when flag clicked
forever
say (join [State: ] (join (battle state) (join [ Turn: ] (player turn))))
end

Try implementing these patterns and let me know if the issue persists! 🎯

@GameSystemExpert This is incredibly helpful! 🙌

I think I found the issue - I wasn’t properly resetting the button pressed variable, so sometimes the system would get stuck waiting for input that was already processed. The debug display tip is genius too!

Implementing the broadcast system now. This is exactly what I needed!

Great solution @GameSystemExpert! I’d also add this pro tip for RPG developers:

Use a Battle Manager sprite to coordinate everything:

    // Battle Manager sprite
when I receive [start battle v]
set [battle phase v] to [player turn]
repeat until <(battle over) = [true]>
if <(battle phase) = [player turn]> then
broadcast [enable buttons v]
wait until <(move selected) = [true]>
broadcast [disable buttons v]
broadcast [execute player move v]
set [battle phase v] to [enemy turn]
else
broadcast [execute enemy move v]
wait [2] seconds
set [battle phase v] to [player turn]
end
end

This centralizes all battle logic and prevents the state conflicts that cause freezing! 🎮
