This event handler I created works great in registering my replacement of BlockOre so that I can load in some additional methods to enable transparent texture support. The problem is when I try to do much the same thing with BlockDoor I run into two problems. One is thrown by the event handler and says "Cannot invoke setHardness(float) on the primitive type void", all the values in that string won't set while it considers TestDoor a void class- I'm a little confused because I looked back over my BlockOre replacer and didn't notice it was returning anything that I could see. I don't know why it's considering y TestDoor a void class/method? package grid.encom.rezcraft; import grid.encom.rezcraft.TestOre; import grid.encom.rezcraft.TestDoor; import net.minecraft.block.Block; import net.minecraft.block.SoundType; import net.minecraft.block.material.Material; import net.minecraft.util.ResourceLocation; import net.minecraftforge.event.RegistryEvent; import net.minecraftforge.fml.common.Mod; import net.minecraftforge.fml.common.eventhandler.SubscribeEvent; @Mod.EventBusSubscriber(modid = TestOre.MODID) public final class EventSubscriber { @SubscribeEvent static void onBlockRegister(final RegistryEvent.Register<Block> event) { event.getRegistry().register(new TestOre().setHardness(3.0F).setResistance(5.0F).setUnlocalizedName("oreIron").setRegistryName(new ResourceLocation("minecraft", "iron_ore"))); event.getRegistry().register(new TestDoor(Material.WOOD)).setHardness(3.0F).setUnlocalizedName("doorAcacia").setRegistryName(new ResourceLocation("minecraft", "acacia_door")); } } Here is my replacement BlockDoor.java - it's just a copy of BlockDoor but it's been modified as TestDoor and is an extension of BlockDoor. This was done to get access to some private methods that weren't easy to get otherwise. package grid.encom.rezcraft; import java.util.Random; import net.minecraft.block.Block; import net.minecraft.block.BlockDoor; import net.minecraft.block.BlockHorizontal; import net.minecraft.block.BlockPlanks; import net.minecraft.block.material.EnumPushReaction; import net.minecraft.block.material.MapColor; import net.minecraft.block.material.Material; import net.minecraft.block.properties.IProperty; import net.minecraft.block.properties.PropertyBool; import net.minecraft.block.properties.PropertyDirection; import net.minecraft.block.properties.PropertyEnum; import net.minecraft.block.state.BlockFaceShape; import net.minecraft.block.state.BlockStateContainer; import net.minecraft.block.state.IBlockState; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.init.Blocks; import net.minecraft.init.Items; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.util.BlockRenderLayer; import net.minecraft.util.EnumFacing; import net.minecraft.util.EnumHand; import net.minecraft.util.IStringSerializable; import net.minecraft.util.Mirror; import net.minecraft.util.Rotation; import net.minecraft.util.math.AxisAlignedBB; import net.minecraft.util.math.BlockPos; import net.minecraft.util.text.translation.I18n; import net.minecraft.world.IBlockAccess; import net.minecraft.world.World; import net.minecraftforge.fml.relauncher.Side; import net.minecraftforge.fml.relauncher.SideOnly; public class TestDoor extends BlockDoor { public static final PropertyDirection FACING = BlockHorizontal.FACING; public static final PropertyBool OPEN = PropertyBool.create("open"); public static final PropertyEnum<TestDoor.EnumHingePosition> HINGE = PropertyEnum.<TestDoor.EnumHingePosition>create("hinge", TestDoor.EnumHingePosition.class); public static final PropertyBool POWERED = PropertyBool.create("powered"); public static final PropertyEnum<TestDoor.EnumDoorHalf> HALF = PropertyEnum.<TestDoor.EnumDoorHalf>create("half", TestDoor.EnumDoorHalf.class); protected static final AxisAlignedBB SOUTH_AABB = new AxisAlignedBB(0.0D, 0.0D, 0.0D, 1.0D, 1.0D, 0.1875D); protected static final AxisAlignedBB NORTH_AABB = new AxisAlignedBB(0.0D, 0.0D, 0.8125D, 1.0D, 1.0D, 1.0D); protected static final AxisAlignedBB WEST_AABB = new AxisAlignedBB(0.8125D, 0.0D, 0.0D, 1.0D, 1.0D, 1.0D); protected static final AxisAlignedBB EAST_AABB = new AxisAlignedBB(0.0D, 0.0D, 0.0D, 0.1875D, 1.0D, 1.0D); protected TestDoor(Material materialIn) { super(materialIn); this.setDefaultState(this.blockState.getBaseState().withProperty(FACING, EnumFacing.NORTH).withProperty(OPEN, Boolean.valueOf(false)).withProperty(HINGE, TestDoor.EnumHingePosition.LEFT).withProperty(POWERED, Boolean.valueOf(false)).withProperty(HALF, TestDoor.EnumDoorHalf.LOWER)); } public AxisAlignedBB getBoundingBox(IBlockState state, IBlockAccess source, BlockPos pos) { state = state.getActualState(source, pos); EnumFacing enumfacing = (EnumFacing)state.getValue(FACING); boolean flag = !((Boolean)state.getValue(OPEN)).booleanValue(); boolean flag1 = state.getValue(HINGE) == TestDoor.EnumHingePosition.RIGHT; switch (enumfacing) { case EAST: default: return flag ?

Looked up registry replacement and I'm not sure how it helps here. I could create a custom bow class, extending ItemBow, and override the onPlayerStoppedUsing method, but I'd prefer to not create custom items either way. -

Or am I supposed to create a json file? And how would I do that? -

Create like a note file? in the .minecraft folder? -

This can be done through registry replacement (i.e. creating custom Tipped Arrows and replacing the vanilla ones)
