How could I write a mod with an algorithm like this:

 

while ServerStarted:

 #Do A.py

 if someoneJoined:

  #Do B.py

if ServerClosed:

  #Do C.py

• FMLServerStartedEvent is fired when the server starts.
• TickEvent.ServerTickEvent is fired twice per tick while the server is running (once at the start with Phase.START, once at the end with Phase.END).
• PlayerEvent.PlayerLoggedInEvent is fired when a player logs in.
• FMLServerStoppedEvent is fired when the server starts.

FMLServerStartedEvent and FMLServerStoppedEvent are FML lifecycle events, so you subscribe to them using @Mod.EventHandler in your @Mod class (like FMLPreInitializationEvent).

 

TickEvent.ServerTickEvent and PlayerEvent.PlayerLoggedInEvent are regular events, so you subscribe to them using @SubscribeEvent in a class registered with the Forge event bus (either manually or with @Mod.EventBusSubscriber).

 

To run Python files, you'll need to use something like Jython.
