They would have to make an API to integrate your mod into theirs.

I've found, in my experience, I always turn to Jabelar's Modding Tutorials. In addition, they also link to other great modder's depending on what you're programming currently.

The first thing anyone will tell you though, is 'Learn the basics of JAVA before trying to mod' for minecraft. It's really not that hard, especially if you've picked up on other programming languages.

Coal actually has a metadata value. Need to use this:

"key": {
    "C": {
      "item": "minecraft:coal",
      "data": 0
    }

In your imports, I noticed you imported Entity from

Entity should be imported from

see if that might help any

I see 3 errors in your crash log. I have you checked all 3 to be sure they are correct?

I tinkered around with addInformation and, this is what I got to work:

@Override
public void addInformation(ItemStack stack, World worldIn, List<String> tooltip, ITooltipFlag flagIn)
{
     super.addInformation(stack, worldIn, tooltip, flagIn);

     tooltip.add("your lore here");
}

I got this idea from looking at the Item#ItemEnchantedBook.class

Caused by: java.lang.IllegalStateException: Attempted to set registry name with existing registry name! New: first:charcoal block Old: first:charcoal block

Do you have 2 blocks with the same name?

Typically if the items you have created in your mod do not show up in minecraft, there is a registry issue somewhere, Where is your Registry Handler Class?

In your recipe, X is 1 item, and Y is another item. Both X and Y are used to make your new (Items.dye, 2, 1)

Sorry to write in this thread with offtopic again, but @MadHatAk am I right with my assumption that you are searching for a mod that adds doors for BoP?

If yes I found one a few years ago. https://minecraft.curseforge.com/projects/doors-o-plenty

Please don't view this post as an advertisement for that mod.

You can not edit Vanilla code but, in your own tool class, you can make gold tools more durable, or what ever.

public enum EnumToolMaterial
{
    // Reduced speed and damage of vanilla items; amethyst is equivalent to diamond
    WOOD(0, 59, 2.0F, -1.0F, 15),
    STONE(1, 131, 3.5F, 0.0F, 5),
    IRON(2, 250, 5.0F, 1.0F, 14),
    EMERALD(3, 1561, 6.0F, 2.0F, 10),
    GOLD(0, 32, 12.0F, -1.0F, 22),
    AMETHYST(3, 4685, 8.0F, 3.0F, 20);

public enum EnumArmorMaterial
{
    // Durability is actual durability of all pieces; diamond has 18 armor points instead of 20
    // with amethyst replacing it
    CLOTH(80, new int[]{1, 3, 2, 1}, 15),
    CHAIN(240, new int[]{2, 5, 4, 1}, 12),
    IRON(240, new int[]{2, 6, 5, 2}, 9),
    GOLD(112, new int[]{2, 5, 3, 1}, 25),
    DIAMOND(1499, new int[]{3, 7, 5, 3}, 10),
    AMETHYST(4499, new int[]{3, 8, 6, 3}, 20);

This gives you some idea of what I mean by "thousands" of changes to vanilla code - more than 3000 changes in the World.java class alone with nearly every single method modified in some way (many of the deletions are due to moving blocks of code, like the lighting code, out to a new class):

If this is really that difficult to do in Forge as to be impractical for the average modder then that just further justifies my view of Forge being a very poor excuse for a "modding" API - more like an "addon" API (i.e. "mods" alter the base game itself while "addons" only add content without changing the base game). This would also explain why Forge mods are so terribly inefficient (try finding a good-size mod that can run with only 256 MB of memory allocated) since you need to add new blocks and items instead of modifying existing ones (e.g. I added 14 new types of walls by extending BlockWall with a class that uses 16 data values instead of 2 with textures taken from the blocks they are based on - no new blocks or textures were added, just a bit of code, and as far as the game is concerned these blocks are "vanilla"; in fact, if you loaded a world with them in vanilla they would not disappear or even lose their metadata unless you mined or placed them).

I found the problem. In my json file, instead of putting "item/generated" I needed to put "item/handheld".

Whenever you're updating a mod to new version and a method seems to disappear you should just look in the class's code and scan through the available methods to see if any are likely the same (with different name or slightly different parameters). In this case I see there is a World#getBiome() method that takes a BlockPos. BlockPos is the modern way where x, y, z are combined in single class to represent a position.

Harry's Tech Reviews is doing a modding series for 1.12. He just got to custom furnaces. It may help.

What have you done so far? Where's the code for your block, your tile entity, your GUI class (with container if necessary), your model, blockstates and registration code?

You're accessing a client-only class from the server. It looks like BiblioCraft is causing the exception.
