Technical Implementation Details

Character Data Configuration

File: c:\Users\egugwen\dj\github\b.w\fight\game\constants.py - Successfully configured Buttys character in CHARACTERS dictionary - Pink color scheme: primary (255, 192, 203), armor (255, 105, 180) - Special attack: "Butter..Butterflys" with magical butterfly theme - Attack names: "Emoji Strike", "Happy Kick", "Butter..Butterflys"

Image Assets Integration

Directory: c:\Users\egugwen\dj\github\b.w\fight\assets\images\ - butterfly-1.png (157KB) → idle animation - butterfly-2.png (72KB) → jumping animation
- butterfly-3.png (259KB) → walking animation - butterfly-4.png (469KB) → punch animation - butterfly-5.png (162KB) → kick animation - butterfly-6.png (95KB) → special attack animation

Issue Resolved: Fixed filename mismatch where butterfly-1'.png (with apostrophe) was renamed to butterfly-1.png to match image loader expectations.

Image Loader Fixes

File: c:\Users\egugwen\dj\github\b.w\fight\game\utils\image_loader.py

Critical Fix: Pygame display mode initialization

# Ensure pygame is initialized with display
if not pygame.get_init():
    pygame.init()
if not pygame.display.get_surface():
    pygame.display.set_mode((1, 1))  # Minimal display for image loading

Root Cause: Pygame's convert_alpha() method requires a display mode to be set. Without this, image loading failed with "No video mode has been set" error.

Character Mapping: Added Buttys sprite mapping

elif character_lower == "buttys":
    action_mappings = {
        "butterfly-1.png": "idle",
        "butterfly-2.png": "jumping", 
        "butterfly-3.png": "walking",
        "butterfly-4.png": "punch",
        "butterfly-5.png": "kick",
        "butterfly-6.png": "special",
    }

Fighter Class Updates

File: c:\Users\egugwen\dj\github\b.w\fight\game\characters\fighter.py

Character Data Handling: Explicit Buttys support

# Get character data - ensure Buttys is properly handled
if name == "Buttys":
    self.character_data = CHARACTERS["Buttys"]
else:
    self.character_data = CHARACTERS.get(name, CHARACTERS["Naruto"])

Width Configuration: Buttys gets wider character model like PEKKA

self.width = 100 if name == "Buttys" else 80

Special Attack Integration: Added Buttys to special attack system

elif self.name == "Buttys":
    # Start enhanced Butterfly
    self.start_butterfly()

Sprite Rendering Fix: Force sprite usage for Buttys

# Force sprite usage for Buttys since it has butterfly images
if self.name == "Buttys" and len(self.sprites) > 0:
    self.render_sprite(screen, render_x, render_y)

Battle Scene Integration

File: c:\Users\egugwen\dj\github\b.w\fight\game\battle\battle_scene.py - Updated AI character selection list to include "Buttys" instead of "PEKKA" - Added butterfly hit callback system for special attack damage - Configured butterfly attack with 60 damage and magical knockback effects

Key Technical Insights

Image Loading Pipeline

1. Character Selection → Image loader checks for character-specific mappings
2. File Resolution → Maps butterfly-N.png files to animation states
3. Pygame Loading → Requires display mode for convert_alpha()
4. Sprite Caching → Uses character_name_skin_index cache keys
5. Rendering → Fighter class chooses between sprite vs drawn rendering

Debugging Process

1. Initial Issue: Buttys showing as Naruto despite correct character data
2. Cache Investigation: Cleared image loader cache, still no sprites loaded
3. File Verification: Confirmed butterfly images exist and are accessible
4. Loading Test: Direct pygame.image.load() worked, but image loader failed
5. Root Cause Discovery: Pygame convert_alpha() needs display mode
6. Solution: Initialize minimal display mode in image loader
7. Final Fix: Force sprite rendering for Buttys character

Performance Considerations

• Image loader uses caching to avoid repeated file I/O
• Butterfly images total ~1.2MB, loaded once per game session
• Sprite scaling applied: 100x120 pixels for Buttys (wider than standard 80x120)
• Background removal processing for non-transparent images

Files Modified

1. fight/game/constants.py - Character data configuration
2. fight/game/utils/image_loader.py - Sprite loading and pygame initialization
3. fight/game/characters/fighter.py - Character logic and rendering
4. fight/game/battle/battle_scene.py - Battle integration
5. fight/assets/images/butterfly-1.png - Renamed from butterfly-1'.png

Verification Status

✅ Buttys character data properly configured
✅ Butterfly images (1-6) successfully loaded
✅ Image loader pygame initialization fixed
✅ Fighter class sprite rendering enabled
✅ Battle scene integration completed
✅ Character width and special attacks configured

Final Result: Buttys character now displays butterfly sprite images instead of falling back to Naruto's drawn character representation.
