[1.7.10][SOLVED] onItemRightClick problems

[Elix_x]

Today i'm having problems with onItemRightClick.

Whenever player clicks on my item, it should disappear. But returning null causes these errors:

So i tried using

player.setCurrentItemOrArmor(0, null);

and returing old item stack

But it works one time in two. Sometimes it disappears, sometimes it stays.

Here's my code:

	@Override
public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer player) {
	if(hasPlayerItems(player)){
		ItemStack newItemstack = new ItemStack(this);
		ItemStack[] playerItems = getPlayerItems(player);
		setItems(newItemstack, playerItems);
		ItemStack[] items = getItems(itemstack);
		for(int i = 0; i < Math.min(items.length, playerItems.length); i++){
			playerItems[i] = items[i];
		}
		setPlayerItems(player, playerItems);
		return newItemstack;
	} else {
		ItemStack[] items = getItems(itemstack);
		ItemStack[] playerItems = getPlayerItems(player);
		for(int i = 0; i < Math.min(items.length, playerItems.length); i++){
			playerItems[i] = items[i];
		}
		setPlayerItems(player, playerItems);
		player.setCurrentItemOrArmor(0, null);
		return itemstack;
	}
}

Why for others returning null works (i read some topics and for them null works)? Why second way glitches? What am i missing?

Any help is appreciated.

 

Thanks for help!

If you have any questions - just ask!

The fuck is all of that code doing? Creating a new stack, then calling a method you didn't show us, then calling another method, then looping over an array...

 

If you want the item to disappear when right-clicked, do this:

 

@Override
public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer player) {
	return null;
}

Nope . Crash. Exactly the one that is shown in crash part. Even if i leave only

return null;

it crashes.

[Elix_x]

This is actually a bug in vanilla 1.7.10 it seems. It tries to check for null on the return value of

onItemRightClick

but the check is broken. So instead of returning

null

return the ItemStack you get passed in but set it's stackSize to 0. It will be nulled out.

I'll try that. Is it only 1.7.10 bug and i can without problems return null in 1.8?

[Elix_x]

I think so, yes.

Ok.

Just checked, it works.

Null

in 1.8 and 0 stack size in 1.7.10.

Thanks!
