Artificial intelligence - machine learning

The bots are not hand scripted or coded. They are genuine machine-learning bots. They start with limited intelligence and learn over time. The more you play, the more they learn. As the bots learn, their knowledge and understanding of the track increases.

Hold the 'k' key to see the heatmap for the track as the bots understand it. Red cells show where the bots think they need to slow down. Yellow and blue cells show where the bots think they need to speed up. This heatmap is constantly evolving and improving. With enough time, the bots will form a perfect heatmap to guide their decision making.

Thanks to darkfrei for always being so helpful

As I click on "Restart career", I get this:

Tested with:

Code: Select all

		if trackknowledge then
			print("Knowledge size = " .. #trackknowledge)
		end

1. Please make the movement with the left mouse button; the right mouse button can be used to move the map.
2. Please highlight the gearbox when the player MUST change/choose the gear. At the start I can click just brakes and not gear was chosen. Also highlight the possible options for the control, make not possible gears as gray, make the dangerous gears as red backlight.
3. After the gear was chosen, make highlighting of possible movements (as step-by-step movement) and end positions (as start-to end movement).
4. The score must be shown in game, and show the AI movements after the player finishing.
5. Add names to AI players and "Player" as player's name

WARNING: uses nativefs to save in non-standard folders. Might not work on every OS

I'm guessing you're not MS Windows. If true then that proves the OS compatibility in a definitive way. Thanks for trying.

edit: my target audience is MS Windows on itch.io but if mac and unix/linux users no the correct way to use nativefs then I'm all ears.

[BrotSagtMist]

Why again are you even saving non standard?

Also big booooo for having a target audience, but then again i usually make sure my crap doesnt work on windows ¯\_(ツ)_/¯

[pgimeno]

It's not about nativefs compatibility across OSes. It's about this:

Code: Select all

    savedir = love.filesystem.getSourceBaseDirectory()
    if love.filesystem.isFused() then
        savedir = savedir .. "\\savedata\\"
    else
        savedir = savedir .. "/FormulaSpeed/savedata/"
    end

First, never use backslashes for files; it works just fine with normal slashes in all currently supported systems. Second, nativefs won't work with files inside a .love file (in any OS), but you can tell people to unpack the .love file and run the directory, if you use this instead:

Code: Select all

    -- set the folders based on fused or not fused
    if love.filesystem.isFused() then
        savedir = love.filesystem.getSourceBaseDirectory() .. "/savedata/"
    else
        savedir = love.filesystem.getSource() .. "/savedata/"
    end

There's a typo in the itch.io filename, by the way.

Update after a (somewhat heated) discussion on IRC:

Using nativefs in this case is not really granted. Your game could reach a wider audience if it uses the regular save directory provided by Löve. You just need to pack the .love file with a data directory containing the initial files, and if they don't exist in the save directory, copy them from source to save. That is as simple as this:

Code: Select all

    if not love.filesystem.getInfo('knowledge.dat') then
        local data = love.filesystem.read("savedata/knowledge.dat")
        love.filesystem.write("knowledge.dat", data)
        data = love.filesystem.read("savedata/racetrack.dat")
        love.filesystem.write("racetrack.dat", data)
    end

then continue using the regular save directory. Under Linux or MacOS, you can even make 'savedata' a symlink to the save folder, to ease the packaging. That's more difficult on Windows as far as I know.

But there are use cases for having the program and data in the same folder. That should be an option, though (e.g. an extra "portable app" download) and not the default.

The discussion on IRC was about how to organize this portable app mode. It's not so easy to check if you're running from a directory or from a .love file, which you have to do if you want to have the data inside the directory in the first case and together with the .love file in the second case. People on IRC disagreed about this organization being a good idea in the first place.

For this use case, you should not provide just a .love file, but a .zip file containing both the .love file and the data directory, similar to how you distribute them in itch.io.
