Analysis: Unused and deprecated code in rocamocha mod code

[Copilot]

Comprehensive static analysis identifying ~419 lines of unused code across 4 files + 2 methods in the rocamocha domain code (actual mod code) without making code changes.

Scope: Analysis focused on rocamocha.* domain code only, excluding bundled third-party libraries (rm_javazoom, org.rm_yaml) which are used for MP3 playback and YAML parsing functionality.

Findings - Rocamocha Code Only

High Priority - Safe Removal (~196 lines)

• ZoneUsageGuide.java (169 lines) - Redundant example code in production source
• BlockSocket.java (17 lines) - Unused socket implementation, 0 instantiations
• Vector3Math.sqrt() method (~10 lines) - Custom implementation marked @SuppressWarnings("unused")

Medium Priority - Requires Evaluation (~223 lines)

• ZoneManagementExamples.java (178 lines) - Example code should be moved to tests
• DamageSourceAdapter.java (35 lines) - Unused adapter with TODO comment suggesting future use
• normalizeSongFileName() method (~10 lines) - Kept "just in case" but 0 calls

Key Findings

✅ Rocamocha codebase is very clean - Only ~419 lines of unused code out of 133 Java files

✅ All other code is actively used:

• All 19 plugin classes
• All mixin accessors (LivingEntityAccess, PlayerEntityAccess, BossBarHudAccessor)
• All adapter classes (except DamageSourceAdapter)
• All socket classes (except BlockSocket)
• NativeAccess, Vector3Math (except sqrt method), Zone management system

Verification

All findings confirmed via:

• grep-based import/reference analysis (0 usages = unused)
• Internal dependency mapping for rocamocha code
• File existence verification
• @deprecated annotation scanning

Comparison with Initial Analysis

Category	Updated Analysis	Initial Analysis
Scope	Rocamocha code only	All code including libraries
Total Unused	~419 lines	~2,500 lines
Files	4 files + 2 methods	22 files + methods

Key Insight: The initial analysis included ~2,000+ lines from bundled third-party libraries. The actual mod code (rocamocha domain) is very well-maintained with minimal unused code.

Original prompt

Please scan the mochamix project for code that is unused or deprecated. Do not make any changes.

List candidates for removal and explain the reasoning behind inclusion in the list.

@copilot Let's try this analysis again, but let's focus on the actual mod code, not the bundled dependencies. So, look mainly in the rocamocha domain in the source.

Analysis refocused on rocamocha domain code only (commit 02fb939).

Key findings:

• Only ~419 lines of unused code in actual mod code (vs ~2,500 previously which included third-party libs)
• Rocamocha codebase is very clean - all plugins, adapters, accessors actively used
• Main unused items: 2 example classes (347 lines), 1 unused adapter (35 lines), 1 unused socket (17 lines), 2 unused methods (~20 lines)

Documents updated:

• ROCAMOCHA_UNUSED_SUMMARY.md - Quick reference

The previous analysis incorrectly focused on bundled libraries (rm_javazoom, SnakeYAML) which are needed for MP3 playback and YAML parsing.
