TM2020-TAS

TM2020-TAS is a TAS tool for Trackmania 2020, written in C++/Python.

Only supported on Windows as this tool uses several Windows API calls.

How does it work?

TM2020-TAS uses a combination of replay input extraction and memory reading to assist in TASes.

Open Trackmania, and load the map you want to TAS.
Open the memory sniffer application. This will attach to Trackmania and monitor the car's location. This is useful for TAS splicing later in the process. This may be replaced if I figure out how to extract ghost car locations from replay files lol
After you've completed the map, save the replay.
Open the replay file with the replay input extractor. This will extract all user inputs during the run.
Open the splicer. This will take in both the monitored car location and the extracted replay inputs. With both of these, you can see exactly where your car was at any point in time.
With the splicer open, you can make a cut at any point, allowing the TAS to play a certain section of the map for you.
If you want to simply optimize a run, you can run the brute force function which will slightly vary the inputs to try and find a faster solution. This is a lengthy process, but is fully automatic.
You're done! Just have the TAS playback the final inputs in the game, save the replay, and enjoy!

As stated above, this tool is very much a work in progress, but this is what has been completed and what is left to do.
