Mood's browser-based raycasting engine can suffer from frame-time instability and render bottlenecks. This Skill helps identify where the main loop spends the most time, enabling targeted optimizations to restore smooth 60 FPS gameplay.
Run the profiler on the Mood engine with the default focus (all) and review the generated bottleneck report to guide optimization.

To profile frame timing in a JavaScript game loop, you instrument the main rendering loop to measure per-frame timings across raycasting, sprite handling, AI updates, and minimap rendering. This identifies exactly where the loop spends the most time.
Frame-time instability in a JavaScript raycaster occurs when the main loop spends inconsistent time on rendering tasks. Instrumenting per-frame timings across raycasting and sprite handling isolates the specific bottleneck causing the stutter.
You measure per-frame timings by instrumenting the main loop to track execution time in specific files like js/raycaster.js, js/sprites.js, js/horde.js, and js/minimap.js. This setup collects targeted metrics for each subsystem.
The best way to optimize for 60 FPS is generating a bottleneck report after instrumenting the frame loop. This report provides actionable recommendations and potential FPS improvements by analyzing sprite-dense and AI-heavy scenarios.
Yes, you need to specify the required files and environment setup to collect metrics effectively. The analysis targets specific modules including js/raycaster.js, js/sprites.js, js/main.js, js/horde.js, and js/minimap.js.
Yes, you can use frame timing instrumentation to guide optimizations for AI-heavy scenarios. The profiler applies its analysis to AI updates alongside raycasting and minimap rendering to recommend targeted fixes.
