Here is a clear breakdown of the exact differences between your original code and the optimized code, highlighting why these changes matter for the performance of a 7 Days to Die mod.
1. The Block Scanning Lag Spike (CheckForRadioPlacement)
Before: When the player placed a radio (detected by their inventory count dropping), your code ran a triple-nested for loop. It checked an 11x7x11 grid around the player, calling GameManager.Instance.World.GetBlock() over 1,180 times in a single frame. This causes massive CPU lag spikes.
After: The game already tells us when a block is placed via your BlockAddedPatch, which populates the PlacedRadios dictionary. Instead of scanning 1,180 blocks, the optimized code just does a simple distance calculation (Vector3.Distance) against the few radios known to exist in PlacedRadios.
2. The String Allocation Memory Leak (UpdateInteractionPrompt)
Before: Every single frame (60+ times a second) that the player looked at a radio, your code fetched the player's keybinding, chopped the file extension off the track name (LastIndexOf('.')), and created a brand new string ($"Press {keyMarkup}..."). This creates heavy "Garbage Collection" (GC) pressure, which causes micro-stutters as Unity cleans up the discarded strings.
After: I added caching variables (lastFocusedPos, lastIsRadioActive, etc.). The prompt string is now built exactly once when you look at the radio, and only updates if the track changes or the radio is paused. The track name without the .mp3 extension is also permanently cached on load.
3. The Dictionary Lookup Bottleneck (GamePrefs.GetFloat)
Before: In UpdateProximityAudio and UpdateInventoryRadio, the code called GamePrefs.GetFloat(EnumGamePrefs.OptionsMusicVolumeLevel) every single frame to check the music slider. GamePrefs is a dictionary lookup under the hood, making it surprisingly slow to call continuously.
After: I c…
