By reading your post again I think I need to use ChoiceConfigurable. And I think that's definitely possible.

@kawaiinekololis say how pls

access to host class net.minecraft.network.play.server.S12PacketEntityVelocity is not allowed or does not exist

You are welcome and I am willing to accept further help requests, would appreciate a example error script or errors in the logs.

Thanks for the reply. Honestly, good point about making an issue on GitHub, I dunno how that hasn't crossed my mind lol. Here's a link to my issue https://github.com/CCBlueX/LiquidBounce/issues/4964. ayaxperson created this issue in CCBlueX/LiquidBounce open [BUG] ScriptAPI mapping issue with method overloading #4964

I figured it out, lol. Just have to do Java.type("net.ccbluex.liquidbounce.utils.aiming.RotationFindingKt"); a.k.a.: add [filename]Kt at the end of the type cause that's just how Kotlin works.

you can use fabric api to click on an item in the GUI.

@HieuNamYT wdym by packet codes? like C08 or smth like that?

It doesn't seem to like mc.gameSettings.keyBindSneak.pressed works, weird.
