Player LogIn event handler and command execution.

[GibbDev]

GDay everybody!

Im quite new to modding and java in general. So my question is how do I do smth when certain player logs in?
Lets say i want to send tellraw message to everybody on server, granted I have uuid of a player coded into mod beforehand.

[GibbDev]

Thanks, It seems it helped.
what about sending tellraw command as server or i should create new topic for that?

 

[GibbDev]

So i managed to do it not via tellRaw class but rather executing comand from server:
player.getServer().getCommands().performCommand(player.getServer().createCommandSorceStack(), "/tellraw @a {\"text\":\"blah blah blah\"}");

Thanks for the help

why would you want to do this via a command, you could simply send a message to the player (ServerPlayer#sendMessage)

[GibbDev]

Cus I want to implement colours and links in message.
Also I know it can be and should be done with tellRawCommand class but my small brain cant get how to do it

 

[GibbDev]

So it would look like this:
server.sendMessage(new TextComponent([same text as tellraw command but without /tellraw @a]), player.getUUID())
?

[GibbDev]

Im so confused with this text component class.
Is there guides or smth where I can get examples of its usage?
How do i make multiple colours in one message?

player.sendMessage(new TextComponent(message).withStyle(color), player.getUUID());

message is an String and color is ChatFormatting#? (BOLD,RED,GOLD, and so on)

[GibbDev]

And what about multiple colours and other functions like hover text and links?

TextComponent works as an builder so you can use after withStyle, append then add a new string there then you can use withStyle again, and so on, ...
test a bit, send several messages to the player in the event with other styles

look at the SeedCommand class
the command use hover and linked text as output (msg after execute the command)

I cant figure out how to embed a link.
I use withClickEvent(ClickEvent.Action.OPEN_URL) but cant seem to find how exactly i would set link

withClickEvent needs an ClickEvent wich needs a ClickEvent.Action and an String, the String should be the URL

[GibbDev]

I put this in code 
.withClickEvent(ClickEvent.Action.OPEN_URL, link)
and it thorws me this error
'withClickEvent(net.minecraft.network.chat.ClickEvent)' in 'net.minecraft.network.chat.Style' cannot be applied to '(net.minecraft.network.chat.ClickEvent.Action, java.lang.String)'

[Luis_ST]

dude this is basic java withClickEvent needs an ClickEvent and not ClickEvent.Action and an String

Ye sry, Java isnt my strongest side and i wont say that i know it well.
Yeah it should be .withClickEvent(new ClickEvent(ClickEvent.Action.OPEN_URL, link))

Thank you guys very much. My small brain tends to lose on those obvious things.
Pleasure doing buisness with you.
