Hello,

 

random results of this code:

 

@SubscribeEvent
public void onPlayerTick(PlayerTickEvent event) {
// Swap HotBar
if (Keyboard.isKeyDown(Keyboard.KEY_B)) {

	if (!event.player.worldObj.isRemote) {

	        int s = 0;
	        
	        ItemStack InvetoryPlayer[] = event.player.inventory.mainInventory.clone();
	        
	        System.out.println("Length = " + InvetoryPlayer.length);
	        
		for (s = 0; s < 9; ++s)
	        {
	        	if(InvetoryPlayer[s] != null){
		        	System.out.println("Slot = " + s + " -> " + InvetoryPlayer[s].getDisplayName());
	        	}
	        	
	        	event.player.inventory.setInventorySlotContents(s, InvetoryPlayer[s+9]);
	        }

		for (s = 9; s < 18; ++s)
	        {
	        	if(InvetoryPlayer[s] != null){
		        	System.out.println("Slot = " + s + " -> " + InvetoryPlayer[s].getDisplayName());
	        	}
	        	
	        	event.player.inventory.setInventorySlotContents(s, InvetoryPlayer[s-9]);
	        }

		InvetoryPlayer = null;
	}
       }
}

 

I need to swap the first inventory line with the hotbar every time i press "B" but it working only sometime.

 

I think a misalignment client/server side ...

 

Also the output is duplicated but this procedure is only server side ... i guess ...

 

Please help.

a) Don't use Keyboard.keyDown, use a keybinding.

b) You will need packets. Keys are client-only.

 

thank you for reply,

 

but i've never understood the packet handler, have you a VERY sample tutorial?

 

I mean i know how to setup one but i dont know how to apply it in my case ...
