release Mitigating Wallhack Exploits: A Comprehensive Fix

[Black_Rose©]

In online multiplayer games, maintaining a level playing field is essential. One of the significant challenges developers face is the use of wallhacks, which allow players to see through objects and gain an unfair advantage. This guide outlines a fix aimed at countering this exploit effectively.

Overview of Modifications

The changes revolve around monitoring player movement and imposing restrictions on how characters can navigate the environment, particularly when they are trying to pass through obstacles. This guide will cover the necessary updates to be made in various code files to implement this system.

Code Adjustments

Step 1: Update Movement Logic in input_main.cpp

The first step is to modify the character movement function to prevent wallhacks. Below is the modified code for the Move function:

In this code block, we check if the character is attempting to move to a location that is not passable. If they are, we keep track of how many attempts they’ve made. If they exceed the allowed amount, we trigger a warp command, preventing them from exploiting the wallhack.

Step 2: Update Character Attributes in char.h

Next, we need to define attributes that store position and wallhack counts within the character class:

This segment defines the necessary properties to track positions and instances of wallhacking, allowing for control over character movement.

Step 3: Add Warp Command in cmd.cpp

We will also need to declare a command that allows for correction of character positions if they exceed the allowed wallhack limits:

Step 4: Handle Command Logic in cmd_general.cpp

Incorporate logic for the new command that will enforce movement restrictions when needed:

This command checks if a player has used wallhacks excessively and teleports them back to their last valid position.

Step 5: Define the Wallhack Limit in service.h

Finally, set the maximum number of wallhack attempts in the service file, allowing for easy adjustments:

This constant will serve as a threshold for how many times a player can attempt to bypass walls before facing restrictions.

With these enhancements, you’ll effectively mitigate the risk of wallhacking exploits in your game, fostering a competitive and fair environment for all players. This implementation not only tightens security but also ensures that the gameplay remains enjoyable and equitable.
