Pull Request Overview
This PR successfully transitions the GetRackCount method to an O(1) lookup using the NetworkMap singleton, meeting the primary objective. However, the current implementation introduces redundant heap allocations via the GetDeviceCounts helper, which creates unnecessary GC pressure in high-frequency polling scenarios—a direct contradiction to the optimization goals stated in the documentation. Although Codacy results indicate the PR is up to standards, there is a noted complexity increase in GameHooks.cs (+3). A significant concern remains regarding the absence of test files in the diff, particularly as the logic involves fallbacks for uninitialized game states that require verification.
About this PR
- The PR description states that the test suite runs correctly, but no new or updated test files were included in the submission. Given the complexity increase and the critical nature of the fallback logic in
GameHooks.cs, automated tests are required to verify the implementation.
Test suggestions
- Verify GetRackCount returns the correct value from NetworkMap index 2 when the singleton is initialized
- Verify GetRackCount falls back to FindObjectsOfType when NetworkMap is null or the counts array length is <= 2
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify GetRackCount returns the correct value from NetworkMap index 2 when the singleton is initialized
2. Verify GetRackCount falls back to FindObjectsOfType when NetworkMap is null or the counts array length is <= 2

🟡 MEDIUM RISK
Suggestion: The GetDeviceCounts method currently allocates a new int[] array on every call, which adds GC pressure if polled frequently (e.g., in UI or Update loops). This negates the performance benefits of the O(1) lookup. Refactor this into a zero-allocation private helper that accesses NetworkMap.instance.GetNumberOfDevices() directly by index with appropriate null and length checks. Update GetServerCount (index 0), GetSwitchCount (index 1), and GetRackCount (index 2) to use this direct access pattern while maintaining the existing FindObjectsOfType fallback.
💡 What: Refactored
GetRackCountinGameHooks.csto useNetworkMap.instance.GetNumberOfDevices()instead ofFindObjectsOfType<Rack>().🎯 Why:
FindObjectsOfTypescans the entire Unity object hierarchy, making it an O(N) operation that causes severe CPU lag and GC allocations in large data center environments. The game already caches the device counts inNetworkMap.📊 Impact: Reduces computational complexity from O(N) to O(1) when fetching the rack count, significantly boosting performance for API queries and eliminating GC pressure.
🔬 Measurement: The test suite runs correctly with the changes, ensuring compatibility and graceful degradation to
