1.20.1 Cant figure out how to use a block as a fuel source

[THEKINGSKULL01]

Hey so I'm really new to Java/Minecraft, coding, as I've followed a few tutorials on YouTube for the Minecraft side of java, But I've been trying to figure out how I can make a custom coal block to be smeltable? I have the "coal" object itself ready and working, but I haven't been able to find a way to make a block smeltable, I know I need to do something with "BlockItem" but I don't understand it at all,

Heres the github to the project to get a better understanding of what I do have set up: https://github.com/THEKINGSKULL01/TSOTD_1.20.1_Forge

This is for Minecraft 1.20.1

public static final RegistryObject<Block> Coal_Crystal_Block = registerBlock("coal_crystal_block",

() -> new FuelBlock(() -> ModBlocks.Coal_Crystal_Block.get().defaultBlockState(), BlockBehaviour.Properties.copy(Blocks.COAL_BLOCK).sound(SoundType.STONE)));

If at all curious, this is what it looks like if you don't check the github

Also I should mention, This is for inellij, not for mcCreator

You need to override the burn time of the corresponding BlockItem, like with this code to register a block that can be used as fuel:
 

private static <T extends Block> RegistryObject<Item> registerFuelBlockItem(String name, RegistryObject<T> block,
		int burnTime) {
	return ModItems.ITEMS.register(name, () -> new BlockItem(block.get(), new Item.Properties()) {
		@Override
		public int getBurnTime(ItemStack itemStack, @Nullable RecipeType<?> recipeType) {
			return burnTime;
		}
	});
}

Sorry I forgot to update the github link, I'm new to github as well so I couldnt figure out how to update it after I was doing something in intellij(Its good now) I have been able to figure out a way by finding another user's code, but from what you sent me (Acting like I'm still really having this issue) how would I do the setup you sent? Would I put it as a separate "FuelBlock" class, ModItems class, or ModBlocks class?

You'd just use this function to register your blocks that you want to be fuels, instead of registerBlock. That's all.

Okay, I think I understand, so it pretty much is another way in creating a block? Because mine looks a tad bit different 

public static final RegistryObject<Block> Coal_Crystal_Block = registerBlock("coal_crystal_block", () -> new Block(BlockBehaviour.Properties.copy(Blocks.COAL_BLOCK).strength(2f).requiresCorrectToolForDrops() .sound(SoundType.STONE).explosionResistance(4)));

Yes, it's just an alternate way of registering blocks. For your example there, you'd just change it to:

public static final RegistryObject<Block> Coal_Crystal_Block = registerFuelBlock("coal_crystal_block", () -> new Block(BlockBehaviour.Properties.copy(Blocks.COAL_BLOCK).strength(2f).requiresCorrectToolForDrops() .sound(SoundType.STONE).explosionResistance(4)), 16000);

The parts in bold are additions. I hope this helps.
