[1.17.1] Executing a command on client when player logs in

[WhiteBear60]

Good afternoon.

I'm trying to write the functionality that I described in the title - for example, when the player logs in, he should automatically greet everyone with /say Hello. I have wrote the following:

 

@Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.FORGE,value = Dist.CLIENT,modid = "examplemod")
    public static class PlayerEvents {
        @SubscribeEvent
        public static void onPlayerLoggedIn(PlayerEvent.PlayerLoggedInEvent event) {
            Minecraft.getInstance().player.chat("/say Test message");
        }
}

but when I trying to load a world, it kicks me with an error that Minecraft.getInstance().player is null. What I'm doing wrong?

PlayerLoggedInEvent is a server side event.

Use ClientPlayerNetworkEvent.LoggedInEvent.

Thank you, looks like that is what I need.

Can I get server IP from this event or check if it is singleplayer or dedicated server?
