Sorry, I was going to post an update thread and just saw this post. The game bots work in two parts:
- Some sort of scheduler that keeps track of games and posts on lemmy
- Access to the specific sport's/team's API
A team's bot like for the Real Madrid community would need access to that team's data (e.g. what games are scheduled when). It gets that data by requesting it from an API. Once it knows when the games are scheduled, the bot can create a post at the appropriate time. The bot will also request specific data about the game (e.g. goals, penalties, etc.) in order to write the post.
The bot basically runs on a loop. It wakes up, checks if there's a game on. If there is one, it creates a post. If it already created a post, it queries for fresh data and updates the post.
The main roadblock for creating new bots is the access to real-time data via an API. Sports leagues often lock this data down and only offer an API to major players in the industry (like sports gambling or media outlets) and charge massive amounts of money for access.
Sorry for the very late reply but I hope that helps!
