The KRX Client is a specialized, third-party mod for the DDraceNetwork (DDNet)—a popular racing version of the Teeworlds engine. While it offers advanced automation and gameplay features, it is often categorized as a "bot" or "cheat" client within the community because it provides tools that are not present in the official legal clients. Common Fixes and Troubleshooting
If the KRX Client is failing to launch or behaving erratically, several standard fixes are recommended in the official documentation:
Execution Errors: If the client does not launch on the first attempt, right-click KRX Client.exe and select "Run as administrator".
Installation Path: Ensure the KRX Client is extracted into its own dedicated folder (e.g., on the Desktop). Do not extract it into your existing official DDNet directory, as this can cause file conflicts.
Discord Integration: If you experience crashes related to Discord Rich Presence, you can toggle it via the command krx_discordrpc. Changing these settings often requires a client restart to take effect.
Rendering Issues: If the game fails to display correctly, go to Settings > Graphics and switch the Renderer to OpenGL 3 or OpenGL 1. Configuration & Performance Fixes krx client ddnet fix
Adjusting specific internal settings is often required to "fix" bot behavior that feels delayed or inaccurate:
Prediction Margin: This is a critical setting for bot accuracy. It should be adjusted based on your ping; if bots are acting erratically due to lag, you should increase this value.
Aimbot Velocity: Recent updates have fixed issues where the hook aimbot would fail at high velocities. Ensure you are running the latest version (updated to DDNet 18.9.1 or higher).
Fake Aim/Ping: Common bugs regarding fake aim modes and fake ping inaccuracies were addressed in late 2024 updates. Key Features and Components
The client is built on the fluffytw library, an open-source framework for DDNet bots. Its features include: The KRX Client is a specialized, third-party mod
Fentbot: An automated bot that switches weapons based on priority (grenade, shotgun, laser) and has enhanced pathfinding.
Visual Enhancements: Customizable HUDs and scoreboard detections that highlight when other players are using suspicious mods. Community Warning
The KRX Client is considered illegal on most official DDrace servers. Using it may lead to:
Server Bans: Official DDNet servers may automatically ban players detected using cheat clients. Clan Dismissal: Many clans strictly forbid its use.
Security Risks: Some community guides warn that unverified third-party clients can occasionally contain malware (Trojan risks). Settings - KRX Client Docs KRX Client Docs Changelog - KRX Client Docs If the problem was related to a disconnection
| Error Message | KRX-Specific Fix |
| :--- | :--- |
| Failed to load font: fonts/DejaVuSans.ttf | Copy the fonts folder from an official DDNet client into your KRX folder. |
| ERROR: could not open 'data/mapres/grass_main.png' | Your DDNet data folder is missing. Set add_path in config to point to official DDNet data folder. |
| Segmentation fault (core dumped) | Usually a memory issue. Disable cl_thread_sound_loading and cl_predict_extra in config. |
| Server is using a different game protocol | Your KRX is too old. You need a recompile or a public patch (see Part 5). |
| Win32 Exception: Access violation | Overlay conflict. Disable MSI Afterburner, RivaTuner, or any FPS counter. |
If the problem was related to a disconnection from the DDNET during peak trading hours, a fix might involve:
# Fix for KRX Client DDNET Disconnection Issue
## Step 1: Update Network Configuration
Ensure the client's network configuration allows for stable and continuous connection to DDNET.
## Step 2: Implement Keep-Alive Packets
Modify the KRX client to send periodic keep-alive packets to DDNET to prevent idle timeouts.
## Step 3: Monitor and Analyze
Continuously monitor the connection status and analyze logs to identify any recurring issues.
## Code Snippet (Example)
# Example in Python to send keep-alive packets
import threading
import time
import socket
def send_keep_alive(sock, interval=60): # 1 minute
while True:
try:
sock.send(b'keep-alive')
except Exception as e:
print(f"Error sending keep-alive: e")
time.sleep(interval)
# Assuming 'sock' is the socket connected to DDNET
keep_alive_thread = threading.Thread(target=send_keep_alive, args=(sock,))
keep_alive_thread.start()
This example illustrates a basic approach to maintaining a continuous connection, which might be part of a solution to disconnection issues.
Outdated configs cause 70% of "freeze on startup" issues.
Pro tip: If you have complex binds, later copy only the bind lines from the old file to the new one. Do not copy gfx_ or cl_predict lines—they change between versions.
Follow these steps in order. Do not skip—many fixes depend on the previous step.
