@ChampionAsh5357 ,Thanks very mush. The most of your advise is useful and your review is amazing. However, I want to explain some things in this tutorial. 1. The useless Class I know these classes looks like useless for programmers who are experinced. But, as my practice I found that using separate class can help newcomers understand code better. So I will not change it. 2. The data generation Actually, I will introduce the Data generation in one chapter. I believe if people can not write json by hand and they will not understand the Data generation. Besides, In some case, people still need write json by hand. 3. About Event registry and other things The top consider for me is translation, I will add contexts and explains latter when I translated this tutorial. 4. About Code Styple. This tutorial actually be written in very short time. I will do full check about the code style. Anyway, Thank you for your advises.

Thanks, BasicParticleType is a convenient class.

Maybe you are right, I should use the TexturedParticle. I want to create a lighting circle and don't think i need the TexturedParticle for this, that's why I don't use the TexturedParticle.

@hiotewdew Thanks for replying. I add the lineWidth to my IParticleRenderType. public class ObsidianParticleRenderType implements IParticleRenderType { public static final ObsidianParticleRenderType INSTANCE = new ObsidianParticleRenderType(); @Override public void beginRender(BufferBuilder bufferBuilder, TextureManager textureManager) { RenderSystem.lineWidth(10.0F); RenderSystem.disableLighting(); RenderSystem.disableDepthTest(); RenderSystem.disableCull(); RenderSystem.enableBlend(); RenderSystem.defaultBlendFunc(); bufferBuilder.begin(GL11.GL_LINE_STRIP, DefaultVertexFormats.POSITION_COLOR); } @Override public void finishRender(Tessellator tessellator) { tessellator.draw(); } } But It's still not working. Could you give some example code?

@TheGreyGhost, I want to render a particle which is just a simple line. But nothing shows in Game.

Introduce: I'm working on making a custom particle from scratch. I want to render a particle which is just a simple line, but nothing shows in game. There are my codes.

Thanks Grey. I just solved this problem. I forge to override the getUpdateTag. Thank you anyway

I write a TileEntity which holds the data in Server side. The server side data sync to client side by getUpdatePacket and onDataPacket. If I exit the Game save and enter it again, The Client Side TileEntity can't get NBT data by read(CompoundNBT compound). But after l put or get Item from the TileEntity, the Data will be synced. How can I let the Client Side TileEntity get the NBT data when the Saves load. Here is my code.

Should Override hasTileEntity(BlockState state) not hasTileEntity()
