Hello. I wanna say special thanks to @kawaiinekololis.
ok so
go to 1.8.9-Forge/1.12.2-Forge and go to src/main/resources/ then find liquidbounce_at.cfg
Open it.
If you are using 1.12.2, add this line:
# CPacketKeepAlive
public net.minecraft.network.play.client.CPacketKeepAlive field_149461_a # key
then it will look like that. 
If you are using 1.8.9, do as 1.12.2, but change CPacketKeepAlive to C00PacketKeepAlive
Profit! Now you can change key to your value. 
this dumb script will disable fly checks on rudesky so you will can fly without getting flagged down (but you will be sometimes setback'ed back)
Tested in BW (3 times), SW
Download script
Install it
Open the game
Enable RedeskyDisabler module
Bind fly & timer together
Set fly mode to Vanilla
Set Vanilla-Speed to 3.4-4.5
Set Timer's Speed to 0.12
Fly without getting flagged down!
RudeskyDisabler.js (RMB -> Save link as)
@gabriel Step 1: Learn how to spell "IntelliJ"
Step 2: Watch yt videos about coding mods for mc in intellij idea
so i understood what do you mean, so press RMB on mc and press "Go to superclass".
So, there you will see all variable definitions
method 2: just type mc. and you will see all available variables
@yorik100 mc.thePlayer.motionX *= mc.thePlayer.motionZ *= 2.28
it is very easy to port lmfao, they should learn anything about liquidbounce 
@dont_doubt CPacketPlayer.CPacketPlayerPosition -> CPacketPlayer.Position
net.minecraft.network.play.client.CPacketPlayer.CPacketPlayerPosLook -> net.minecraft.network.play.client.CPacketPlayer.PositionRotation
@elias smth like blockesp
also: .bind clickgui rshift
type this into chat
public class HelloWorld {
private static void print() {
System.out.printf("Hello World!");
}
}
public class Test {
public static void main(String[] args) {
HelloWorld.class.getDeclaredMethod("print").invoke(null);
}
}
@indomsgods rename .kt to .java and then to .class it will work
