[TUTORIAL] how to make blocks with item stack limit [100% works in 1.20.1]

Code mostly made by my friend Enderlord

first you need to find a place where mcreator register all your items

urMod->Source(Gradle)->net->urMod->init->urModItems

and then add this code:

	static {
		blockWithProp(ModIdModblocks.BLOCKNAME, BLOCKNAME, () -> new Item.Properties().stacksTo(MaxStackNumberYouWant));
    // put more blocks if you want
	}

	private static RegistryObject<Item> blockWithProp(final RegistryObject<Block> block, final RegistryObject<Item> old, final java.util.function.Supplier<Item.Properties> props) {
		if (old == null)
			return REGISTRY.register(block.getId().getPath(), () -> new BlockItem(block.get(), props.get()));
		java.util.Objects.requireNonNull(props);
		try {
			var field = net.minecraftforge.registries.DeferredRegister.class.getDeclaredField("entries");
			field.setAccessible(true);
			var map = (java.util.Map<RegistryObject<Item>, java.util.function.Supplier<? extends Item>>) field.get(REGISTRY);
			map.put(old, () -> new BlockItem(block.get(), props.get()));
			return old;
		} catch (java.lang.Exception e) {
			return null;
		}
	}

[dont forget to change ModId to Your Mod id

and max stack number to an actual number

same with BLOCKNAME

you can get its name upper in urModItems class:

	public static final RegistryObject<Item> TestBlock = block(SowModBlocks.TestBlock);
                                                ↑ (this one)            (or this ↑)

ALSO put code between

// start of user code block custom item

// end of user code block custom item
