[Show recipe items in a string when holding a certain button (item tooltip)]

Got it fixed, air returns as null in the array so calling item.getItemName() was crashing it.

[Show recipe items in a string when holding a certain button (item tooltip)]

Okay, i tried using the CraftingDeconstructor class, and I'm doing it like this:

	List<String> d = new ArrayList<String>();
	CraftingDeconstructor decon = new CraftingDeconstructor();

	ItemStack[] ingredients = decon.getDeconstructResults(item);

	for (ItemStack i : ingredients) {
		d.add(i.getUnlocalizedName());
	}

	return d;

But it is throwing a NPE in it:

Sorry if this is a basic mistake, I'm not sure what is making the error

[Show recipe items in a string when holding a certain button (item tooltip)]

hello, I was recently playing a 1.6.4 modpack and saw ICBM has recipes in the lore when holding J (http://prntscr.com/cdkvwq). Is there any way I can do this in my mod? Getting the recipe for an itemStack, I already know how to do the lore based on keys held. I had a look in the CraftingManager class but found nothing that could help. Thanks for any help!

[Gradle build fails]

Thank you! That fixed my problem completely!

[Gradle build fails]

Hi, i have been having a problem with building my mod. when i run gradle build, it fails saying

error: multi-catch statement is not supported in -source 1.6
                } catch (NumberFormatException | ArrayIndexOutOfBoundsException ex) {
                                               ^
  (use -source 7 or higher to enable multi-catch statement)

Is there any way I can change gradle to build with java 1.7? I have looked it up a few times but nothing seemed to work... Thanks in advance.

[How to set a hollow cuboid (or get a list with the blocks / locations in it)]

Got this sorted out! Thanks for helping!

[How to set a hollow cuboid (or get a list with the blocks / locations in it)]

hello, I am trying to make a block that makes a hollow cube around it from one location to another. I know how to set blocks and all, but i have no idea how I could get a hollow cube. Any help is appreciated! Thanks in advance!

[Items not being added to custom CreativeTabs]

I got this fixed, thanks for all the help! Turns out it was because i was setting the tabs in preInit(or not?), but once i moved the tab setting into Init it worked fine. Thanks for the help again!

[Items not being added to custom CreativeTabs]

Hello, I'm relatively new to modding but not java, and i was trying to add new items and blocks. Everything is working so far, except the creativetab part. I can get my items with /give, but they are just not showing in my creative tab. I am creating the creativetab like so:

modTab = new ModTab("testmod", wrench);

, and my ModTabs constructor is:

public ModTab(String label, Item i) {
	super(label);
	tabIcon = i;
}

.

I register my items with a method called 'register', and inside that it registers them to gameregistry and sets the creativetab:

private void register(Item item){
	GameRegistry.registerItem(item, item.getUnlocalizedName());
	item.setCreativeTab(modTab);
}

. I also have one for blocks, the same but with registerBlock. Any help would be appreciated!

 

P.S. Sorry for formatting issues, new to forum
