The Fent Bot in KRX Client is an advanced, experimental tool for automating map completion. It is primarily designed for KoG (King of Gores)-style maps and requires significant computational resources.
Console Bind: You can toggle the Avoid bot (when Fentbot is selected) using: bind KEY toggle krx_avoidfreeze 1 0 (replace KEY with your desired key). Note that enabling this mainly starts the Fentbot's calculation process.
Prediction Note: Remember to set cl_prediction_margin based on your ping (e.g., cl_prediction_margin 70 for 50ms ping) for optimal performance during calculation and potential playback (if used with TAS).
CPU Intensive: Fentbot performs complex, asynchronous calculations in the background. It can consume significant CPU resources, potentially impacting game performance, especially on lower-end systems or with high configuration settings.
(Note: Screenshot may slightly differ from the latest version).
(Settings controlling the Fentbot calculation process)
Player Prediction: Enables prediction of other players' movements during the pathfinding calculation. This allows the bot to potentially find paths that avoid other players but significantly increases calculation complexity and time.
Advanced Settings: Unlocks detailed customization options for the bot's calculation parameters. If disabled, uses pre-defined "Quality" settings.
Fent Ticks: The maximum duration (in ticks) the bot will simulate ahead during its path calculation process. Higher values allow finding solutions for longer map segments but increase computation time.
Tweaker Inputs (krx_avoid_tile_fent_tweaker_actions): Higher values explore more potential input sequences, but increase CPU load. (Only available if Advanced Settings is ON).
Tweaker Ticks (krx_avoid_tile_fent_tweaker_ticks): Controls the number of consecutive inputs evaluated for each cycle. Longer sequences can solve more complex maneuvers but increase calculation time. (Only available if Advanced Settings is ON).
Tweaker Dosage (krx_avoid_tile_fent_tweaker_dosage): Controls the number of the tests. Bigger "dosage" allows for better optimization of input sequences but significantly increase computation time. (Only available if Advanced Settings is ON).
Quality Setting: (Only available if Advanced Settings is OFF). Selects predefined sets of Tweaker/Fent parameters (Low, Mid, Max) offering a trade-off between calculation speed and solution quality.
Inject Fent: This button toggles the main Avoid bot (krx_avoidfreeze). When Fentbot is the selected agent, enabling this starts the asynchronous pathfinding calculation process in the background. Disabling it should stop the calculation.
(Settings related to visuals and tunnel management)
Render Path: Displays the calculated path (sequence of positions) visually in the game world once found.
Render Tunnels: Highlights the areas defined as "tunnels" (valid movement areas) visually. Useful for visualizing ares where fentbot can't go.
Spectate Scan: Allows spectating the bot's simulated progress during the calculation phase. The camera will attempt to follow the bot's current best-known position in the simulation. Requires being in spectator mode.
Tunnel Editor: Enables a mode where you can manually define restricted movement areas ("tunnels"). Left-click might remove tiles from the tunnel (making them impassable for the bot), Right-click might add them back. This directly influences the pathfinding calculation.
Auto Tunnels: Automatically generates a restricted movement tunnel based on the path taken in a loaded TAS replay file (*.tas). The bot will then only search for solutions within this defined tunnel.
Tunnel Width: Adjusts the width (in tiles) of the auto-generated tunnel around the replay path.
Clear Tunnels: Removes all manually created and auto-generated tunnels, resetting the pathfinding area to the entire map (minus standard obstacles).
Light Tile Support: Allows Fentbot to consider paths through freeze tiles if an unfreeze tile is nearby, potentially finding solutions on maps with "light freeze".
Radius: Defines the search radius around a freeze tile within which an unfreeze tile must exist for the light tile logic to apply.
For most users, starting with the default settings or a predefined Quality Setting (Low/Mid/Max) is recommended.
Advanced Settings: Only enable if you understand the impact of the Tweaker parameters on performance and solution quality. Higher values dramatically increase CPU usage and calculation time.
A possible configuration for high-end CPUs:
Player Prediction: OFF (unless specifically needed)
Advanced Settings: ON
Fent Ticks: 1000-10000 (depending on map segment length)
Tweaker Inputs: High (e.g., 500-1000+)
Tweaker Ticks: 8-16 (adjust based on maneuver complexity)
Tweaker Dosage: High (e.g., 100-300+)
Tunnels: Using Auto Tunnels with a previously recorded (even imperfect) TAS replay can significantly speed up calculation by drastically reducing the search space. Manually defining tunnels with the Tunnel Editor can achieve the same but requires more effort.
Start Calculation: Use the Inject Fent button to start the pathfinding process. Be patient, as calculations can take minutes or even hours depending on settings and map complexity.
