OMG i got it working with your help
The
mc.player.dropSelectedItem(false)
and
mc.player.inventory.selectedSlot = 1
when combining them with a for loop which goes from 0 to 8 will drop all slots in the hotbar
Thank you for helping me. I can now finally finish the script. Thank you very very much
Maybe someday i will write another help request (hopefully only maybe)
Again thank you very much for your help 
so just a question what is this code snipped trying to archive
should it drop the players mainhand or hotbar or inventory?
and will it even work
i am sorry but its a bit hard to understand
i got this now and removed the timer
run: function() {
Client.displayChatMessage(Dropping Item);
inventory = mc.player.getInventory()
itemStack = inventory.getStack(1)
mc.player.dropItem(itemStack, false)
}
So i got this its not the complete script but the rest works i just need to drop the hotbar
for (let i = 0; i < 9; i++) {
let dropTask = new TimerTask({
run: function() {
var inventory = mc.thePlayer.getInventory();
var itemStack = inventory.getStackInSlot(i);
if (itemStack !== null) {
mc.thePlayer.dropItem(true, itemStack);
Client.displayChatMessage(`Dropped items from slot ${i + 1}`);
} else {
Client.displayChatMessage(`Slot ${i + 1} is empty.`);
}
}
});
timer.schedule(dropTask, delay);
}
Hi Guys,
i recently dived into custom scripts and i would like that the player drops the current main hand slot i have tried already multiple things from different forums and also tried to do my own research in this "fabric" (yarn) library and on the "documentation" of LB but i just cant figure it out if you could help me with that it would be very nice.
Thank you in advance,
