Posted August 16, 201411 yr I am trying to run a method when someone pulls out the item on the hot bar. So if the item is in the third slot and the player switches to that I need it to run a method. How would I do that?
August 16, 201411 yr Two ways that *I* know (there is probably more) Items have an onUpdate method (currently vanilla maps use this) @Override public void onUpdate(ItemStack par1ItemStack, World par2World, Entity par3Entity, int par4, boolean par5) { // TODO Auto-generated method stub super.onUpdate(par1ItemStack, par2World, par3Entity, par4, par5); if (par3Entity instanceof EntityPlayer) { EntityPlayer player = (EntityPlayer)par3Entity; if (player.getHeldItem().equals(par1ItemStack) && player.inventory.getStackInSlot(2).equals(par1ItemStack)) { //Do stuff } } } Hotbar slots in the players inventory is 0-8 (1 to 9 left to right) now this way it runs like every tick, I normally build my own cool down system but that gets glitchy if you have many of the same item (including other players having the item) Second would be to make your own event that checks the livingUpdateEvent or a event that fits better. Currently updating my Mod to 1.10.2 https://bitbucket.org/hugo_the_dwarf/riseoftristram2016/src?at=master
August 16, 201411 yr Author When ever I put the item in the hot bar it crashes. I did try changing one thing because I want it to run that code everytime the item is pulled out not just in slot 2. @Override public void onUpdate(ItemStack par1ItemStack, World par2World, Entity par3Entity, int par4, boolean par5) { super.onUpdate(par1ItemStack, par2World, par3Entity, par4, par5); if (par3Entity instanceof EntityPlayer) { EntityPlayer player = (EntityPlayer)par3Entity; if (player.getHeldItem().equals(par1ItemStack)) { System.out.println("Test"); } } }
August 16, 201411 yr Ah I bet the error is null pointer exception? what is the error that the console spits out? Currently updating my Mod to 1.10.2 https://bitbucket.org/hugo_the_dwarf/riseoftristram2016/src?at=master

August 16, 201411 yr hmm... works for me just fine. @Override public void onUpdate(ItemStack par1ItemStack, World par2World, Entity par3Entity, int par4, boolean par5) { // TODO Auto-generated method stub super.onUpdate(par1ItemStack, par2World, par3Entity, par4, par5); if (par3Entity instanceof EntityPlayer) { EntityPlayer player = (EntityPlayer)par3Entity; if (player.getHeldItem() != null) { if (player.getHeldItem().equals(par1ItemStack)) { System.out.println("test"); } } } } Currently updating my Mod to 1.10.2 https://bitbucket.org/hugo_the_dwarf/riseoftristram2016/src?at=master
August 16, 201411 yr Author It looks like I messed up something. I got it working now. Thank you so much for your help.
August 16, 201411 yr no problem, just remember there are probably other ways out there to do what you want, and they might be better. Currently updating my Mod to 1.10.2 https://bitbucket.org/hugo_the_dwarf/riseoftristram2016/src?at=master
August 17, 201411 yr Yup, the way hugo_the_dwarf suggested is the 'right' way to do it if you're using your own custom item. If you needed to do this with a vanilla item, however, then you'd be using either the LivingUpdateEvent or the TickEvent.PlayerTick. BEFORE ASKING FOR HELP READ THE EAQ! I'll help if I can. Apologies if I do something obviously stupid. If you don't know basic Java yet, go and follow these tutorials.
