Bell of Companions

Added:

• Full compatibility with Minecraft 1.21.11 (Fabric)
• Placeable Pet Bell block with floor, ceiling, and wall attachment support
• Redstone activation for the Pet Bell block (resonate sound + enchant particles)
• Block-specific config: block_recall_range, block_recall_cooldown_seconds, block_particle_intensity, block_settings_mode
• Reliable advancement unlock on bell ring (item or block) and on placing the block

Changed / Fixed:

• Pet List distance display now uses blocks; out-of-range shows max+ blocks
• Config loading now falls back to defaults safely and normalizes all values
• Tag detection uses dual CCA + command tag check with legacy pet tag auto-migration
• Recall scan results are throttled and reused per player for performance
• Tameable checks use cached reflection lookups for modded entities
• Fixed default config migration (block_settings_mode → "tool", particles → "minecraft:heart")
• Fixed placement advancement triggering on non-Pet Bell block placements
• Fixed Pet Bell support model particle texture
• Fixed fox trust detection

1.21.11-specific fixes:

• Fixed world creation freeze (CCA component serialization mismatch)
• Fixed UI crashes (Can only blur once per frame)
• Fixed blank pet list entries
• Fixed pack metadata parsing (supported_formats, min_format/max_format)
• Fixed pet list stability (reverted experimental cache path, stabilized entity previews)
• Fixed unlimited recall scan bounds (now uses full build height)
• Fixed block entity state validation crash on placement
