[1.15.2] How to make custom TNT

[someRandomKid]

I have already made a custom TNT entity and a custom TNT block using the vanilla classes. 

But, How do I render the custom TNT?

You need an entity renderer...look at vanilla TNTRenderer

[someRandomKid]

I have already tried that, I just get an invisible entity.

Do I have to stitch my texture into the atlas?

Did you bind your entity renderer to your entity? You can do that with RenderingRegistry.registerEntityRenderingHandler

yes, I already have.

Basically I get no errors in the output log, but the entity is invisible.

All right, can you show your code please?

public class MegaTNTRenderer extends EntityRenderer<MegaTNTEntity> {

	@Override  
    public void render(MegaTNTEntity entityIn, float entityYaw, float partialTicks, MatrixStack matrixStackIn, IRenderTypeBuffer bufferIn, int packedLightIn) {
        matrixStackIn.push();
        matrixStackIn.translate(0.0D, 0.5D, 0.0D);
        if ((float)entityIn.getFuse() - partialTicks + 1.0F < 10.0F) {
            float f = 1.0F - ((float)entityIn.getFuse() - partialTicks + 1.0F) / 10.0F;
            f = MathHelper.clamp(f, 0.0F, 1.0F);
            f = f * f;
            f = f * f;
            float f1 = 1.0F + f * 0.3F;
            matrixStackIn.scale(f1, f1, f1);
        }

        matrixStackIn.rotate(Vector3f.YP.rotationDegrees(-90.0F));
        matrixStackIn.translate(-0.5D, -0.5D, 0.5D);
        matrixStackIn.rotate(Vector3f.YP.rotationDegrees(90.0F));
        TNTMinecartRenderer.renderTntFlash(RegistryHandler.MEGA_TNT.get().getDefaultState(), matrixStackIn, bufferIn, packedLightIn, entityIn.getFuse() / 5 % 2 == 0);
        matrixStackIn.pop();
        super.render(entityIn, entityYaw, partialTicks, matrixStackIn, bufferIn, packedLightIn);
    }

    public MegaTNTRenderer(EntityRendererManager renderManager) {
        super(renderManager);
        this.shadowSize = 0.5F;
    }

    @Override
    public ResourceLocation getEntityTexture(MegaTNTEntity entity) {
        return PlayerContainer.LOCATION_BLOCKS_TEXTURE;
    }
}

Tell me if you need more code.

Show also the MegaTNTEntity class please

[someRandomKid]

public class MegaTNTEntity extends Entity {
    private static final DataParameter<Integer> FUSE = EntityDataManager.createKey(MegaTNTEntity.class, DataSerializers.VARINT);

        this.setPosition(x, y, z);
        double d0 = worldIn.rand.nextDouble() * (double)((float)Math.PI * 2F);
        this.setMotion(-Math.sin(d0) * 0.02D, 0.2D, -Math.cos(d0) * 0.02D);

    }

            }
        } else {

            if (this.world.isRemote) {
                this.world.addParticle(ParticleTypes.SMOKE, this.getPosX(), this.getPosY() + 0.5D, this.getPosZ(), 0.0D, 0.0D, 0.0D);

    protected void explode() {
        float f = 20.0f;
        new_swords.LOGGER.info("exploding?");
        MinecraftServer server = this.getServer();
        if(server == null)
            return;
        ServerWorld world = server.getWorld(this.dimension);
        world.createExplosion(this, this.getPosX(), this.getPosYHeight(0.0625D), this.getPosZ(), f, Explosion.Mode.BREAK);

    }

    public void notifyDataManagerChange(DataParameter<?> key) {
        if (FUSE.equals(key)) {
            this.fuse = this.getFuseDataManager();
        }

    }


    /**
     * Gets the fuse from the data manager
     */
    public int getFuseDataManager() {
        return this.dataManager.get(FUSE);
    }


    public @NotNull IPacket<?> createSpawnPacket() {
        return new SSpawnObjectPacket(this);
    }
}

 

[Beethoven92]

This code seems to be the problem:

    public @NotNull IPacket<?> createSpawnPacket() {
        return new SSpawnObjectPacket(this);
    }

You cannot use the vanilla spawn packet here, you need to override createSpawnPacket with:

return NetworkHooks.getEntitySpawningPacket(this);

otherwise your entity will be existing only on the server and so invisibile to you on the client

[someRandomKid]

Works now, but since my fuse is 40 longer than the vanilla fuse, my tnt disappears too early.

I fixed the bug, thanks for helping!
