Write in a sign from a forge mod

[McPqndq]

Hello,

 

I'm currently making a mod for game automation, and I would need the mod to automaticly write something on a sign.

I tried to simulate keyboard keys using the java Robot class, but it only send keys to the current active window, and not to the game, if it's not active...

I was wondering if there is a "forge" way to write something in a sign.

 

Is it possible ?

What version is this for?

Ideally it would be for 1.12.2, but apparently this version isn't supported anymore here, so maybe 1.15.2

Signs have tile entities that store their text. You can access it that way.

Thank you for your answer, but how am I supposed to do that ?

 

Is it the correct way to get the sign's tile entity ? :

TileEntitySign tileEntitySign = (TileEntitySign) Minecraft.getMinecraft().world.getTileEntity(new BlockPos(0, 0, 0));

This is client side only.

Either:

• Your mod needs to be client side only (in which case, it can't make changes).
• You need to access the TE via a server world.

I'm sorry I didn't understand your message...

You mean that if the mod is client side only, it's not possible ? My mod is client side only

You could read the text of the sign, but you can't change it, because of this pesky thing called "server authoritative model."

That is, the server is the absolute authority on the state of the game, and that state includes the text on signs. Without code on the server to change that text, you can't.

Even if the sign is opened on the player's screen and you can write on it manually ?

Vanilla has code to handle that, but that doesn't mean you can hook into it and make it do what you want.

[McPqndq]

So there is no way to do that ?

That's a far cry from "no way".
