I created a throwable rock item and I can throw it but the entity is not rendered.

This is called during client setup:

RenderingRegistry.registerEntityRenderingHandler(EntityRock.class, new IRenderFactory<Entity>()
{
  @Override
  public EntityRenderer<? super Entity> createRenderFor(EntityRendererManager manager)
  {
  	return new SpriteRenderer(manager, Minecraft.getInstance().getItemRenderer());
  }
});

 

I found setCustomClientFactory() when creating the entity type but I don't know if I must use it?

solved: used setCustomClientFactory() and overwritten createSpawnPacket()

What you have is fine, however you need to override createSpawnPacket in your Entity class and give it your own IPacket that spawns the entity in the handle method and basically does what SSpawnObjectPacket does. But for your Entities/Entity.

Why we need to override createSpawnPacket ? i don't get it .. ?

Because the vanilla one doesn't work for modded entities unless they are living. The packet takes specific information like the entities Unique ID and position and velocity and spawns the same entity on the client with all of that data. If you don't override createSpawnPacket then the client won't know that that entity exists.

mm Okay ..
But how to implement this function?

public void processPacket(IClientPlayNetHandler handler) {...}

cause this function : handler.handleSpawnGlobalEntity take only SSpawnGlobalEntityPacket ..

Don't use that function..

By handle method here I meant the processPacket method.

Nothing .. like i said, i don't know how to implement this .. so i have nothing ..

Which part are you having problems with. Creating the entity that sent the packet? Use EntityType#create(Minecraft.getInstance().world)

 

You don't know how to spawn the Entity? Minecraft.getInstance().world.addEntity

 

What is it that you are having difficulty with?

I know how to spawn the entity :

CustomProjectil projectilEntity = new CustomProjectil(worldIn, playerIn);
projectilEntity.shoot(playerIn, playerIn.rotationPitch, playerIn.rotationYaw, 0.0F, 1.5F, 1.0F);
worldIn.addEntity(projectilEntity);

it's what i need to put in "processPacket" method ...

I literally told you what needs to go there... you need to create an entity and spawn it in the client world.

I have try

@Override
public void processPacket(INetHandler handler) {
   Entity entity = new CustomProjectil(Minecraft.getInstance().world, x, y, z);
   Minecraft.getInstance().world.addEntity(entity);
}

 

i have try many things like this, but doesn't seem to work

i'm feel stupid

Edited September 15, 20196 yr by fanor

Well i have solved it with

@Override
public IPacket createSpawnPacket() {
   return NetworkHooks.getEntitySpawningPacket(this);
}
