(Java) Sending text + newline to Runescape

I'm writing an autotalker. It works great in general purpose applications like Notepad and even Old School Runescape, but it doesn't work in modern Runescape for some weird reason.

If you select the option to add a new line at the end of your message, modern RS will move the chat window to the search window (as if it had pressed enter first before sending a message):


Then it'll search for the autotalker's output.

The character sequence is as simple as this: "hello\n" as an example. I've tried combinations with \r as well.

My code is simple, I'm not doing anything crazy. Just using the Robot class.
Here's my code:

Code:

package botkitfx.Classes;

import java.awt.*;
import java.awt.event.*;
import java.util.Random;

public class KeyController
{
    Robot robot;
 
    public KeyController() throws AWTException
    {
        robot = new Robot();
    }
 
    public void SendChar(char c)
    {
        int keycode = KeyEvent.getExtendedKeyCodeForChar(c);
        robot.keyPress(keycode);
    }
 
    public void SendKeys(String text, int humanDelay, int humanOffset, boolean newline)
    {
        char[] textArr = text.toCharArray();

        for(char c : textArr)
        {
            int trueDelay;
            if (humanOffset > 0 && humanDelay > 0)
                trueDelay = humanDelay + (new Random()).nextInt(humanOffset);
            else if(humanOffset == 0 && humanDelay > 0)
                trueDelay = humanDelay;
            else
                trueDelay = 0;
         
            SendChar(c);
        }
     
        if (newline == true)
        {
            SendChar('\n');
        }
    }
}

Usage:

Code:

SendKeys("hello", 0, 0, true);

Sending VK_ENTER with Robot yields the same effect.

Ideas?

EDIT:
Basic SendKeys.Send() code in C# doesn't invoke the search box, but it glitches out pretty heavily:

This was trying to send "Boogers\n"

 

I don't play runescape anymore so I'm not familiar with the interface. I worked with Robot a few years ago (also Java) and if I can recall correctly, adding some delay between key sends fixed a lot of the weird behavior I was getting compared with no delay. Perhaps the game is having trouble interpreting your new line because it is coming in so fast? In runescape, is typing \n supposed to start a new line?

 

Robot works with literal key presses so it uses keycodes instead of chars. Translating the char \n to a keycode is the equivalent of telling Robot to type "enter", so it should work fine. I haven't tried adding a delay though, I'll report back soon.

EDIT: Added a simple Thread.sleep(50); and it works as intended now. Thx pal <3
