Frame Window Counter

A comprehensive frame window tracking, HUD customization, and $L^*$ (NaNDL Precision) calculation toolkit for Geometry Dash (Geode).

Features

Frame Window Tracking & Visuals

• In-Game Markers: Spawns animated markers on player positions during gameplay corresponding to specific frame actions and window tolerances.
• Live HUD Statistics: Customizable HUD overlay in the top-left corner tracking action counts across configured frame window ranges.
• Custom Audio Effects: Bind dedicated sound effects (.ogg, .mp3) to specific frame window presets.
• Camera Compatibility: Full world-to-screen matrix transformations ensuring markers properly track through rotations, zoom, and reversed gravity.

Advanced Precision Calculator ($L^*$)

• Multi-Dimensional Metrics: Solves for theoretical level precision across 8 dimension combinations:
  • Base ($L^*$)
  • Nerve ($K_T$) — Time-dependent decay
  • Fatigue ($K_U$) — Input count-dependent decay
  • CPS ($K_C$) — High click-frequency penalty
  • Composites: N+F, N+C, F+C, and All (N+F+C)
• Multi-Threaded Asynchronous Solver: Fast root-finding algorithm using an error function (erfc) LUT lookup table.
• Configurable Calculation Parameters:
  • Level TPS: Target calculation rate (synced with macro FPS).
  • Respawn Time (s): Accounts for penalty time from death back to start.
  • Target Solve Time (s): Expected completion time benchmark (default: 86,400s / 24 hours).
  • Model Constants: Fine-tune $K_T$, $K_U$, and $K_C$ up to 16 decimal places with one-click default restore.
• Dirty State Indication: Automatically highlights $L^*$ values in red when frames or settings are modified without recalculating.

Action Editor & Macro Tooling

• Timeline Tracking: Automatically highlights and scrolls to the active frame in real-time as the level plays.
• Dual Player (1P/2P) Control: Toggle individual action player assignments on the fly.
• Import & Export:
  • Import replay/macro files (.gdr, .gdr2, .slc, .json, .fwc).
  • Export custom binary .fwc and NaNDL .json project files.
• Automated Safety Backups: Background autosaves generated periodically to the Geode config directory.

How to Use

1. Frame Window Presets & Labels

1. Open the Windows or Labels popup from the bottom bar of the main editor.
2. Configure Min/Max Frame Windows, custom HUD label text, colors, and audio file triggers.
3. Enable Show in HUD to display a live tally during gameplay.

2. Importing & Editing Frames

1. Click Import in the main editor to load a macro or replay file (.gdr, .gdr2, .slc, .json, .fwc).
2. Edit frame numbers, frame window tolerances, or switch between 1P and 2P modes.
3. Use Activate All / Inactivate All to bulk toggle drawing and HUD inclusion.

3. Calculating Precision ($L^*$)

1. Click the Options gear icon in the top-right of the Frame Editor to open the Precision Display popup.
2. Toggle your desired metrics (Base, Nerve, Fatigue, CPS, etc.).
3. (Optional) Click the top-right gear in the Precision Display to open L Calc Settings* to configure TPS, respawn time, target solve time, or model constants.
4. Click Start Calculation. Once finished, cycle through metrics on the top status button or view live values in the bottom-left corner during level runs.
