I don't understand, how can I listen to events in FabricMC (1.20)

I'm new to mod developement, tried it firstly today. I want to make event, that will trigger when player joins a singleplayer or multiplayer world. How can I do this?

Also, I'm really sorry for wasting your time if its a dumb question.

Tried to search in Google, and find nothing...

Correct me if I'm wrong, but it sounds like you want to register an event handler rather than create a new event.

I'm unsure if you want your event handler to trigger client-side or server-side, so I will provide examples for both.

Note that the server-side event will be triggered on the dedicated server when joining a multiplayer world, and on the client's integrated server when joining a singleplayer world. See this page of the Fabric Wiki for more details on that.

Client-side

import net.fabricmc.fabric.api.client.networking.v1.ClientPlayConnectionEvents;

// put this in your mod initializer method
ClientPlayConnectionEvents.JOIN.register((handler, sender, client) -> {
    // get the player
    var player = client.player;
    // handle the event here...
});

Server-side

import net.fabricmc.fabric.api.networking.v1.ServerPlayConnectionEvents;

// put this in your mod initializer method
ServerPlayConnectionEvents.JOIN.register((handler, sender, server) -> {
    // get the player
    var player = handler.player;
    // handle the event here...
});
