Random track selection for custom cups

[Jakal]

First of all: Thank you for all your work on RVGL, it is simply fantastic. Especially the custom cups feature has breathed new life into the game for me.

One thing i would love to see would be randomized track selection for custom cups though. So for example that i could create a "Random Cup" cup txt file that contained 10 stages with 10 laps in the following format:

STAGE 0 random 10 false false
STAGE 1 random 10 false false
[and so on]

Where "random" would be a placeholder for any installed track and the cup would contain different tracks each time. Maybe even the mirrored and reversed parameters could be randomized in the same way.

I tried to use ChatGPT to create a batch file that generates new random cups on each game launch and got pretty far, but the batch file got super complicated and still contains a couple of formatting errors that i can't seem to fix.

Would adding something like that to the rvgl code be a possibility?

Very interesting that you tried using ChatGPT. I guess you had no prior coding experience?
I like the idea, although I'm not sure if it should go into the custom cup functionality. In any case, sharing these does not make much sense, as different people will have a different collection. At the same time, it might be the easiest way to implement it, because most of the functionality is already there.
I would like to hear what others think.

I think it could be very interesting. It's worth a try.

I have very little actual coding experience, but basic understanding of how code works, if that makes sense. Over the years i helped myself with several (mostly game-related) tedious tasks by copying together stuff using google, but ChatGPT has been a godsend for me in that regard. I actually have a working batch file now that creates 5 different random cups per difficulty level, based on whatever tracks i have in the levels subfolder and then launches the game. The code is super super dirty and not very flexible, as a lot of variables like number of laps, number of cars etc. are fixed, but hey, it works

An official implementation would still be much appreciated if doable. I agree that it would probably be best put in its own submenu, like maybe adding another selection after selecting "Championship" that has 3 options for the official cups, the custom cups and creating a new randomized cup... But that's just an idea, not sure if that's the best way to go.

Right, i might as well share this random cup generator, now that it works pretty well, maybe it can be of use for some people. Disclaimer: I am not responsible if your Computer spontanously explodes or any other damages happen when you run the script, yada, yada

Instructions: Just copy the code below to a new .bat file in the Re-Volt root directory. On launch you can define the number of stages you like per cup and the number of laps per stage, as well as if you like reverse and mirrored mode randomization. Other variables like the total number of cars, the points system and the number of total cups generated are fixed, as i have no need for that to be flexible.

The script will then generate a total number of 30 random cups, 5 per difficulty level, and save them in the cups folder. Whenever you run the script again, previously generated random cups will be overwritten.

Wrote a python script that is really easy to update. Just run the script under your "cups" folder.
Enjoy!
