Bruteforce

Bruteforce refers to an automated method used in TrackMania to optimize race times by systematically adjusting inputs to discover faster routes or techniques. This approach is a cornerstone of tool-assisted speedruns (TAS), where players leverage software tools to achieve precision and performance beyond human capabilities.

Overview

In the context of TrackMania Nations Forever and TrackMania United Forever, **TMInterface** is a widely used TAS tool that includes a built-in bruteforce script. This script enables users to automatically search for faster race times by simulating thousands of input variations derived from an existing replay. When the script identifies a faster time, it records the new inputs and saves them for the user to review.

How it Works

The bruteforce script in TMInterface functions by:

Utilizing an original replay that completes the track as a baseline.
Generating small, systematic modifications to the inputs in the replay.
Running simulations to determine whether the adjusted inputs result in a faster time.
Saving the best-performing results to a `result.txt` file for further analysis.

The process requires a valid replay of a completed race. Incomplete replays lack sufficient input data for the bruteforce script to function effectively.

Features

TMInterface’s bruteforce script includes several customization options:

**Objective Definition**: Users can target specific goals, such as optimizing checkpoint times or custom triggers placed on the track.
**Speed Optimization**: By leveraging TrackMania’s validation feature, the script runs simulations at maximum speed, testing thousands of variations quickly.
**Save States**: The tool supports save states to restore specific points in the race, reducing the time required to evaluate each modification.

These features enable users to tailor the bruteforce process to the unique challenges of any given track.

Usage

To initiate the bruteforce process: 1. Select a valid replay that completes the track. 2. Launch the bruteforce script via TMInterface. 3. A console window will open, displaying the progress of the optimization process. 4. Review the `result.txt` file generated by the script to analyze the optimized inputs.

Applications

Bruteforce is particularly useful in:

Identifying faster racing lines.
Refining inputs for complex track sections.
Exploring new strategies and techniques that may not be apparent through manual play.

The efficient use of save states and rapid simulations has enabled TrackMania players to achieve unprecedented times, pushing the boundaries of what is possible within the game.
