[1.19] [SOLVED] Render mini entites inside block entites like spawner

[FantaLaTone]

I have a block entity and a block entity renderer class. I want to render an entity inside block and I am kinda able to do that. When I first placed the block everything works fine. But when I save & load back the world entity is gone. How I can save the entity on server-side or render entity without spawning it. I need some answers how I can do that?

Block Entity Class

Spoiler

package com.fantalatone.mobblocks.block.entity;

public class AnimatedCageBlockEntity extends BlockEntity {
    public Entity insideEntity;
    public String insideEntityType;

    public AnimatedCageBlockEntity(BlockPos pPos, BlockState pState) {
        super(ModBlockEntities.ANIMATED_CAGE_BLOCK_ENTITY.get(), pPos, pState);
    }

    public static void tick(Level pLevel, BlockPos pPos, BlockState pState, AnimatedCageBlockEntity pBlockEntity) {
        System.out.println("ENTITY->\n"+ pBlockEntity.insideEntity + "\n");
    }
  
    @Override
    protected void saveAdditional(CompoundTag tag) {
        tag.putString("insideEntity", this.insideEntityType);
        super.saveAdditional(tag);
    }

    @Override
    public void load(CompoundTag tag) {
        this.insideEntityType = tag.getString("insideEntity");
        super.load(tag);
    }
}

 

Base Block Class

Spoiler

public class AnimatedCageBlock extends BaseEntityBlock {

    private final String entity;

    public AnimatedCageBlock(Properties pProps, String type) {
        super(pProps);
        this.entity = type;
    }

    @Nullable
    @Override
    public BlockEntity newBlockEntity(BlockPos p_153215_, BlockState p_153216_) {
        return new AnimatedCageBlockEntity(p_153215_, p_153216_);
    }

    @Override
    public void setPlacedBy(Level p_49847_, BlockPos p_49848_, BlockState p_49849_, @Nullable LivingEntity p_49850_, ItemStack p_49851_) {
        AnimatedCageBlockEntity e = (AnimatedCageBlockEntity) p_49847_.getBlockEntity(p_49848_);
        e.insideEntityType = entity;
        e.insideEntity = ForgeRegistries.ENTITY_TYPES.getValue(new ResourceLocation(this.entity)).create(p_49847_);

        super.setPlacedBy(p_49847_, p_49848_, p_49849_, p_49850_, p_49851_);
    }

    @Nullable
    @Override
    public <T extends BlockEntity> BlockEntityTicker<T> getTicker(Level p_153212_, BlockState p_153213_, BlockEntityType<T> p_153214_) {
        return createTickerHelper(p_153214_, ModBlockEntities.ANIMATED_CAGE_BLOCK_ENTITY.get(),
                AnimatedCageBlockEntity::tick);
    }

    @Override
    public RenderShape getRenderShape(BlockState p_49232_) {
        return RenderShape.ENTITYBLOCK_ANIMATED;
    }
}

Renderer Class

Spoiler

public class RendererAnimatedCageBlock implements BlockEntityRenderer<AnimatedCageBlockEntity> {

    private final BlockEntityRendererProvider.Context context;
    private final EntityRenderDispatcher entityRenderer;

    public RendererAnimatedCageBlock(BlockEntityRendererProvider.Context ctx) {
        this.context = ctx;
        this.entityRenderer = Minecraft.getInstance().getEntityRenderDispatcher();
    }

    @Override
    public void render(AnimatedCageBlockEntity tile, float partialTicks, PoseStack stack, MultiBufferSource bufferIn, int combinedOverlayIn, int combinedLightIn) {
        final BlockRenderDispatcher dispatcher = this.context.getBlockRenderDispatcher();

        dispatcher.renderSingleBlock(Blocks.WHITE_STAINED_GLASS.defaultBlockState(), stack, bufferIn, combinedOverlayIn, combinedLightIn,
                ModelData.builder().build(), RenderType.cutoutMipped());

        stack.pushPose();
        stack.translate(0.5f, 0f, 0.5f);
        stack.scale(0.75f, 0.75f, 0.75f);

        if (tile.insideEntity != null) {

            float f = 0.53125F;
            float f1 = Math.max(tile.insideEntity.getBbWidth(), tile.insideEntity.getBbHeight());
            f *= 1.5f;

            stack.translate(0.0D, (double)0.4F, 0.0D);
            stack.translate(0.0D, (double)-0.2F, 0.0D);
            stack.scale(f, f, f);

            entityRenderer.setRenderShadow(false);
            entityRenderer.render(tile.insideEntity,
                    0.0d, 0.0d, 0.0d,
                    0.0f, 0.0f, stack, bufferIn, 15);
        }
        stack.popPose();
    }
}

You don't want to store data in your Block like that. The whole point of the BlockEntity is to store data.

What you are missing is networking code to send the server's block entity state to the client. e.g. when the game reloads the data

I think you need to use the SRGG nname instead of mapped ones

 

Ah, wrong thread.

I made it using initializing an entity in every tick. It worked for me.
