I am creating a mod that adds new armor sets and changes how armor sets are crafted. When the player interacts with the block it fails to open the gui, but I get no error or stacktrace. All of my registration classes are being called correctly. LightArmorBenchScreen's constructor, render, and renderbg methods are not being called at all. Here is the code: package net.leeveygames.celestial.blocks.custom; import net.leeveygames.celestial.Celestial; import net.leeveygames.celestial.blocks.entity.CelestialBlockEntities; import net.leeveygames.celestial.blocks.entity.LightArmorBenchBlockEntity; import net.minecraft.core.BlockPos; import net.minecraft.server.level.ServerPlayer; import net.minecraft.world.InteractionHand; import net.minecraft.world.InteractionResult; import net.minecraft.world.entity.player.Player; import net.minecraft.world.level.BlockGetter; import net.minecraft.world.level.Level; import net.minecraft.world.level.block.BaseEntityBlock; import net.minecraft.world.level.block.Block; import net.minecraft.world.level.block.RenderShape; import net.minecraft.world.level.block.entity.BlockEntity; import net.minecraft.world.level.block.entity.BlockEntityTicker; import net.minecraft.world.level.block.entity.BlockEntityType; import net.minecraft.world.level.block.state.BlockState; import net.minecraft.world.phys.BlockHitResult; import net.minecraft.world.phys.shapes.CollisionContext; import net.minecraft.world.phys.shapes.VoxelShape; import net.minecraftforge.network.NetworkHooks; import org.jetbrains.annotations.NotNull; import org.jetbrains.annotations.Nullable; public class LightArmorBenchBlock extends BaseEntityBlock { public static final VoxelShape SHAPE = Block.box(0, 0, 0, 16, 12, 16); public LightArmorBenchBlock(Properties pProperties) { super(pProperties); } @Override public VoxelShape getShape(BlockState pState, BlockGetter pLevel, BlockPos pPos, CollisionContext pContext) { return SHAPE; } @Override public RenderShape getRenderShape(BlockState pState) { return RenderShape.MODEL; } @Override public void onRemove(BlockState pState, Level pLevel, BlockPos pPos, BlockState pNewState, boolean pIsMoving) { if (pState.getBlock() != pNewState.getBlock()) { BlockEntity blockEntity = pLevel.getBlockEntity(pPos); if (blockEntity instanceof LightArmorBenchBlockEntity) { ((LightArmorBenchBlockEntity) blockEntity).drops(); } } super.onRemove(pState, pLevel, pPos, pNewState, pIsMoving); } @NotNull @Override public InteractionResult use(BlockState pState, Level pLevel, BlockPos pPos, Player pPlayer, InteractionHand pHand, BlockHitResult pHit) { if(pLevel.isClientSide()) return InteractionResult.SUCCESS; BlockEntity be = pLevel.getBlockEntity(pPos); if (be instanceof LightArmorBenchBlockEntity blockEntity) { ServerPlayer player = (ServerPlayer)pPlayer; Celestial.LOGGER.info("Opening Screen."); NetworkHooks.openScreen(player, blockEntity, pPos); } return InteractionResult.CONSUME; } @Nullable @Override public BlockEntity newBlockEntity(BlockPos pPos, BlockState pState) { return new LightArmorBenchBlockEntity(pPos, pState); } @Nullable @Override public <T extends BlockEntity> BlockEntityTicker<T> getTicker(Level pLevel, BlockState pState, BlockEntityType<T> pBlockEntityType) { if(pLevel.isClientSide()) { return null; } return createTickerHelper(pBlockEntityType, CelestialBlockEntities.LIGHT_ARMOR_BENCH_BLOCK_ENTITY.get(), (pLevel1, pPos, pState1, pBlockEntity) -> pBlockEntity.tick(pLevel1, pPos, pState1)); } } package net.leeveygames.celestial.screen; import net.leeveygames.celestial.Celestial; import net.leeveygames.celestial.blocks.CelestialBlocks; import net.leeveygames.celestial.blocks.entity.LightArmorBenchBlockEntity; import net.minecraft.network.FriendlyByteBuf; import net.minecraft.world.entity.player.Inventory; import net.minecraft.world.entity.player.Player; import net.minecraft.world.inventory.*; import net.minecraft.world.item.ItemStack; import net.minecraft.world.level.Level; import net.minecraft.world.level.block.entity.BlockEntity; import net.minecraftforge.common.capabilities.ForgeCapabilities; import net.minecraftforge.items.SlotItemHandler; public class LightArmorBenchMenu extends AbstractContainerMenu { public final LightArmorBenchBlockEntity blockEntity; private final Level level; public LightArmorBenchMenu(int pContainerId, Inventory inv, FriendlyByteBuf extraData) { this(pContainerId, inv, inv.player.level().getBlockEntity(extraData.readBlockPos())); Celestial.LOGGER.info("Creating Light Armor Bench Menu.
