Hello,

I have this question:

How can I get the item ID the player is holding in hand and save it into variable with sub-blocks (itemDmg)?

Whats the function for it and how to use it?

Maybe eg. code?

 

Best regards,

Ernio

You can get the currently equipped item of the player by using

Minecraft.getMinecraft().thePlayer.getCurrentlyEquippedItem()

I believe. This will return an ItemStack, and you can do what you wish with that.

I found it (yesterday) before your answer, but thanks anyway.

Everything works fine, but one thing - what does this returns when you have nothing in your hand?

private int ScrollID = 0;
public boolean onBlockActivated(World var1, int var2, int var3, int var4, EntityPlayer player, int var6, float var7, float var8, float var9)
{
	if (!player.isSneaking())
	{
		Item item = Minecraft.getMinecraft().thePlayer.getCurrentEquippedItem().getItem();
		if(item == Main.Plan) this.ScrollID = 11;
		player.openGui(Main.instance, this.ScrollID, var1, var2, var3, var4);
		this.ScrollID = 0;
		return true;
	}
	else
	{
		return false;
	}
}

When I rightclick with fist (empty hand) it crashes and says that ,,Item item = Minecraft.getMinecraft().thePlayer.getCurrentEquippedItem().getItem();" is a wrong call - NullPointer

Also note: When this.ScrollID = 0; GuiHandler calls null.

 

Thanks in advance,

Ernio

1. Don't use the Minecraft class within methods which are called (also) serverside! THere's a player instance given in the onBlockActivated method parameters

2. check in your if statement if player.getCurrentEquippedItem() is not null
