can't pass an extended or copied version of that class.

Create your own. Start thinking like a programmer. You need to create your own ItemStackTileEntityRenderer which handles your Spear item. God why do you have to have everything put right in front of you on plain paper.

Step 1. Create Your own ItemStackTileEntityRenderer implementation and override renderItem(ItemStack)

Step 2. Duplicate what the Trident does, but with your own model.

Step 3. Set it in your Items Properties with the Item.Properties#setTEISR

Step 4. Create thrown entity by extending the TridentEntity

Step 5. Create renderer that renders the your spear model at the entities position/angle etc.

Step 6. Make sure everything works.

Excuse me no need to be rude, a better question is why you don't fully read / understand what I am typing to you. I already tried making my own "ItemStackTileEntityRenderer", hence "copied version of that class". There is no use as the method "Item.Properties#setTEISR" only accepts "import net.minecraft.client.renderer.tileentity.ItemStackTileEntityRenderer", specifically. No other path is accepted, so there is nothing I can do here it seems.

I have been looking at "TridentEntity" already, and have had my own renderer class for a while, mind you I have been programming Java for some time and have made other mods (non-forge), and even android applications, I am not foreign to these concepts. I can do steps 4 - 6 but it would be pointless since I can't set any other "ItemStackTileEntityRenderer" than the vanilla one.

Then you have done.

public class MyOwnItemStackTileEntityRenderer extends ItemStackTileEntityRenderer

Yes indeed, as stated in previous post, the method does not accept extended classes of "ItemStackTileEntityRendererB".

I'm not very familiar with Renderers, so it's probably best to get someone else's input.

If you dig around in Minecraft's files (as it seems you've done a couple posts prior), you'll notice there's a model/trident.json and a model/trident_in_hand.json. I assume "in_hand" is the one representing the item you hold. You'll notice the parent is builtin/entity, which means it is using a registered Entity as a model. This means you'll need to create and register an Entity to serve as the model of your Item, as well as hold other important information. If you want to see vanilla example of creating Entities, check Minecraft's EntityType (You want to do this. There a a couple things I'm leaving out, such as defining hitboxes).

With Forge you register an Entity (or rather, an EntityType) a little differently than vanilla. It's basically the same as other Objects in Forge, and nearly identical to TileEntityTypes. Since I couldn't find any specific documentation on registering them, here's an example:
    //Entities
    @ObjectHolder("wabbit")
    public static final EntityType<WabbitEntity> wabbit = null;

    @SubscribeEvent
    public static void registerEntities(final RegistryEvent.Register<EntityType<?>> event) {
        LOGGER.debug("Wabbits: Registering Entities...");
        event.getRegistry().registerAll(
                EntityType.Builder.create(WabbitEntity::new, EntityClassification.AMBIENT)
                .build("wabbit").setRegistryName(Constants.MOD_ID, "wabbit");
        );
    } //registerEntities()
There are other files you'll likely want to create, such as a SpearModel (since it looks like you're making a spear). The best thing to do is just search "Trident" in you IDE and look at all the .java and .json files. Piece together what each thing does, and do your best to throw a spear together. You'll learn more as you go along and be able to come back to improve your spear.

EDIT: Also, note that when you make your Renderer, you'll also need to register it. you do that like this:
RenderingRegistry.registerEntityRenderingHandler(WabbitEntity.class, RenderWabbitFactory.INSTANCE);
The second value is a factory. Take a look at this for more info. (https://stackoverflow.com/questions/37126170/irenderfactory-help-in-minecraft-forge)

i apologize, I totally missed this reply of yours. I have indeed seen those files, there are three actually, another is trident_throwing.json. Anyways i have done the following :

@Mod.EventBusSubscriber(bus=Mod.EventBusSubscriber.Bus.MOD)
    public static class RegistryEvents {
    	
    @SubscribeEvent
    public static void registerEntities(final RegistryEvent.Register<EntityType<?>> event) {

    LOGGER.debug("Hello from Register Entities");

    event.getRegistry().registerAll(

    	EntityType.Builder.create(Spear_Entity::new, EntityClassification.AMBIENT).build("spear").setRegistryName("mymod", "spear")
    );

    RenderingRegistry.registerEntityRenderingHandler(Spear_Entity.class, Spear_Factory.INSTANCE);
  }
}

Something is still amiss, how is my actual "SpearRender" class linked to my "SpearEntity" class? So I made this "Spear_Factory" class great, where does the important stuff hook in? Thanks btw.

Yes I did, I got it now, i had to implement some thing in the "Spear" class, and then pass it in to the method. The Renderer piece is still missing though, see the above post.

Do RenderingRegistry.registerEntityRenderingHandler() in your ClientSetupEvent

I moved the line there but still, my renderer is not being used. The parameters for that call are as follows :

RenderingRegistry.registerEntityRenderingHandler(Spear_Entity.class, Spear_Factory.INSTANCE);

So the question remains, where does Spear_Renderer fit in? I am guessing it has to be linked to the Spear_Factory, as of right now that class does nothing other than "implement IRenderFactory<Spear_Entity>" :

package mymod;

import net.minecraft.client.renderer.entity.EntityRenderer;
import net.minecraft.client.renderer.entity.EntityRendererManager;
import net.minecraftforge.fml.client.registry.IRenderFactory;

public class Spear_Factory implements IRenderFactory<Spear_Entity> {
	
	public static final Spear_Factory INSTANCE = new Spear_Factory();

	@Override
	public EntityRenderer<? super Spear_Entity> createRenderFor(EntityRendererManager manager) {
		
		return null;
	}
}

There has to be more.

Why are you returning null here. It needs to return your renderer.

Oh right, my bad, new to making entities and rendering...

package mymod;

import net.minecraft.client.renderer.entity.EntityRenderer;
import net.minecraft.client.renderer.entity.EntityRendererManager;
import net.minecraftforge.fml.client.registry.IRenderFactory;

public class Spear_Factory implements IRenderFactory<Spear_Entity> {
	
	public static final Spear_Factory INSTANCE = new Spear_Factory();
	private Spear_Renderer spear_Renderer = new Spear_Renderer(null);

	@Override
	public EntityRenderer<? super Spear_Entity> createRenderFor(EntityRendererManager manager) {
		
		spear_Renderer = new Spear_Renderer(manager);
		
		return spear_Renderer;
	}
}

Still chucking tridents....

Oh...then your Item is still spawning Tridents...you need to override onStoppedUsing or whatever it is called.

Oh right it had trident entities in that method, I changed all of that which required me to update my "Spear_Entity" class and include another super constructor :

package mymod;

import net.minecraft.entity.EntityType;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.entity.projectile.TridentEntity;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class Spear_Entity extends TridentEntity {

	public Spear_Entity(EntityType<? extends TridentEntity> p_i50148_1_, World p_i50148_2_) {
		
		super(p_i50148_1_, p_i50148_2_);
	}

	public Spear_Entity(World worldIn, PlayerEntity playerentity, ItemStack stack) {

		super(worldIn, playerentity, stack);
	}
}

However this causes a problem inside of a line of code that previously worked fine :

   @SubscribeEvent
        public static void registerEntities(final RegistryEvent.Register<EntityType<?>> event) {
        	
            LOGGER.debug("Hello from Register Entities");
            
            event.getRegistry().registerAll(
            		
            	EntityType.Builder.create(Spear_Entity::new, EntityClassification.AMBIENT).build("spear").setRegistryName("mymod", "spear")
            );
            
        	RenderingRegistry.registerEntityRenderingHandler(Spear_Entity.class, Spear_Factory.INSTANCE);
        }

The "EntityType.Builder.create(Spear_Entity::new, EntityClassification.AMBIENT)" part is underlined in red in Eclipse with the following message : "Cannot infer type argument(s) for <T> create(EntityType.IFactory<T>, EntityClassification)". But this only happens when I have that second constructor in the entity class.

This is a Java error you could probably look this statement up in a generic way and find an answer.

You are right, I shouldn't have asked that here.

MineModder2000 · August 29, 2019

Well I learned the basics of generics and got the jist of it. This is my Spear_Entity class now :

package mymod.spear;

import net.minecraft.entity.EntityType;
import net.minecraft.entity.EntityType.IFactory;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.entity.projectile.TridentEntity;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class Spear_Entity extends TridentEntity implements IFactory<Spear_Entity> {

    public Spear_Entity(EntityType<? extends TridentEntity> p_i50148_1_, World p_i50148_2_) {
        
        super(p_i50148_1_, p_i50148_2_);
    }

    public Spear_Entity(World worldIn, PlayerEntity playerentity, ItemStack stack) {

        super(worldIn, playerentity, stack);
    }

    @Override
    public Spear_Entity create(EntityType<Spear_Entity> p_create_1_, World p_create_2_) {

        return null;
    }
}

But now I don't know which parameters to pass to the first constructor that is invoked here (the second one is called from my Spear extends Item class) :

   @SubscribeEvent
        public static void registerEntities(final RegistryEvent.Register<EntityType<?>> event) {
        	
            LOGGER.debug("Hello from Register Entities");
            
            event.getRegistry().registerAll(
            		
            	EntityType.Builder.create(new Spear_Entity(null, null), EntityClassification.MISC).build("spear").setRegistryName("mymod", "spear")
            	//EntityType.Builder.create(EntityClassification.MISC).build("spear").setRegistryName("mymod", "spear")
            );
            
        	RenderingRegistry.registerEntityRenderingHandler(Spear_Entity.class, Spear_Factory.INSTANCE);
        }

By "first constructor," I assume you mean "new Spear_Entity(null , null)" inside of Builder#create. Instead of giving it an Entity, give it an IFactory, like so:

Spear_Entity::new

Typo

MineModder2000 · September 2, 2019

I created my own throwable entity by copying (not extending) the EggItem and EggEntity classes. All works great, however the item breaks when hitting grass (as eggs do) when I want it to go through (like arrows and tridents do). Anyone have any idea how to make this happen? It just needs to ignore grasses...

In the onImpact method you have to check to see if the block is passable or not.

Yes I am familiar with this method and have already explored this, but could not figure out any way to check for such.

RayTraceResult.Type.BLOCK

The block variable here is not the same as the Block class, so it doesn't have "is passable" and related methods, and cannot be compared to grass blocks and such. Sorry I should've mentioned all this in the OP.

True, but if you had looked into other instances of ThrowableEntity you would have found that if the Type is BLOCK then you could cast the RayTraceResult to BlockRayTraceResult and then get the Block's position in the world and get it from the World.

Ah I see. Well I am trying this just as a test but getting console error :

     if (result.getType() == RayTraceResult.Type.BLOCK && this.world.getBlockState(((BlockRayTraceResult)result).getPos()).getBlock() == Blocks.GRASS) {
            
            ((EntityRayTraceResult)result).getEntity().attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), damage);
            this.world.setEntityState(this, (byte)3);
            this.remove();
        }

It's too much to even post.

Ok all is fine here you check if its type is BLOCK and then check if the block is grass. Good good.

((EntityRayTraceResult)result).getEntity().attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), damage);

Then you immediately cast it to an EntityRayTraceResult even though the type is not ENTITY...
WHY? JUST WHY?

Oh boy, this is a face palm for me ?. I had it written differently last night, and it wasn't working so I tried to test that line alone to see what would happen, forgetting the different types / casting. Chalk it up to late night brain fog. I have this now :


    	if (result.getType() == RayTraceResult.Type.BLOCK && this.world.getBlockState(((BlockRayTraceResult)result).getPos()).getBlock() == Blocks.GRASS) {
    		
    		System.out.println("no");
    	}
    	
    	else if (result.getType() == RayTraceResult.Type.ENTITY) {
        	
        	((EntityRayTraceResult)result).getEntity().attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), damage);
        	this.world.setEntityState(this, (byte)3);
        	this.remove();
        }

But it's going through all blocks, not just grass.
