Hello, I've created an entity and I would like help giving it a chance to spawn in villages.

Also for future reference, how do I spawn my mobs in a certain biome in general?

Since you are using a texture, almost everything within PlayerRenderer is worthless to you. You could literally just replicate SkeletonRenderer or some other BipedRenderer and be fine with it. As for PlayerModel, it depends on what you are trying to do with it. If you are using any of the overlay layer on the skin, you probably will need to use PlayerModel. Else, you can just get away with BipedModel and going from there.

Thanks for your advice! I ended up using a PlayerModel as I needed the outer skin thing, and for my Renderer i used BipedRenderer. Cheers

[How would I go about creating an entity with the same model as the player?]

Hello, I'd like some pointers on how to go about creating an entity with the model of a player. I want it to have my custom texture, which is just a normal player skin.

I was thinking that for my renderer class, I could extend LivingRenderer because PlayerRenderer does, override getEntityTexture to have the skin i want to use, and then copy over the relevant code from PlayerRenderer, but it doesnt seem like that'll work.

As for my model class, should I even make my own? Or can I just use PlayerModel? 

Any guidance would be appreciated, thank you

 

[Issues with my projectile]

4 hours ago, poopoodice said:

Is it not spawning or not being rendered?

I'm guessing it's not spawning? Because the arrow is supposed to create an explosion but it's not happening.

 

 

UPDATE: I've tried using /summon to spawn my entity and my game crashes. Here's what happens:

[Issues with my projectile]

Hey everybody, I have an entity based off of ArrowEntity that doesn't seem to be spawning. When I trigger onPlayerStoppedUsing it doesnt do anything. It does print the debug message "player stopped using staff" but nothing else

I'm 99% sure the issue is with the way I register it because mostly everything was working before I messed with that. I was trying to create my own EntityType as before I was using a constructor that didn't take EntityType as an argument to spawn my entity.

Here is how I'm spawning my entity:

public class ExplosionStaff extends BowItem {

    public ExplosionStaff() {
        super(new Item.Properties().group(ItemGroup.COMBAT));
    }

    @Override
    public void onPlayerStoppedUsing(ItemStack stack, World worldIn, LivingEntity playerIn, int timeLeft) {
        ExplosionSpellEntity spell = new ExplosionSpellEntity(RegistryHandler.SPELL_ENTITY.get(), worldIn);
        int i = this.getUseDuration(stack) - timeLeft;
        float f = super.getArrowVelocity(i);
        spell.shoot(playerIn, playerIn.rotationPitch, playerIn.rotationYaw, 0.0F, f * 4.0F, 0.2F);
        worldIn.addEntity(spell);
        System.out.println("Debug: player stopped using staff");
    }

}

How I'm registering the entity: 

public class RegistryHandler {

    public static final DeferredRegister<Item> ITEMS = new DeferredRegister<>(ForgeRegistries.ITEMS, Megumin.MOD_ID);
    public static final DeferredRegister<EntityType<?>> ENTITY_TYPES = new DeferredRegister<>(ForgeRegistries.ENTITIES, Megumin.MOD_ID);

    public static void init() {
        ITEMS.register(FMLJavaModLoadingContext.get().getModEventBus());
        ENTITY_TYPES.register((FMLJavaModLoadingContext.get().getModEventBus()));
    }

    // Items
    public static final RegistryObject<Item> STAFF = ITEMS.register("explosion_staff", ExplosionStaff::new);
    public static final RegistryObject<EntityType<ExplosionSpellEntity>> SPELL_ENTITY = ENTITY_TYPES.register("spell",
            () -> EntityType.Builder.<ExplosionSpellEntity>create(ExplosionSpellEntity::new, EntityClassification.MISC)
                    .size(1f, 2f).build(new ResourceLocation(Megumin.MOD_ID, "spell").toString()));
}

 

The actual entity:

public class ExplosionSpellEntity extends ArrowEntity {

    public ExplosionSpellEntity(EntityType<? extends ArrowEntity> type, World worldIn) {
        super(type, worldIn);
    }

    public ExplosionSpellEntity(World worldIn, double x, double y, double z) {
        super(worldIn, x, y, z);
    }

    public ExplosionSpellEntity(World worldIn, LivingEntity shooter) {
        super(worldIn, shooter);
    }

    @Override
    public void onHit(RayTraceResult raytraceResultIn) {
        System.out.println("Debug: spell entity hit");
        this.world.createExplosion(this, this.getPosX(), this.getPosY(), this.getPosZ(), 20, false, Explosion.Mode.DESTROY);
        this.remove();
    }

    @Override
    public void tick() {
        super.tick();
        Vec3d vec3d = this.getMotion();
        double d3 = vec3d.x;
        double d4 = vec3d.y;
        double d0 = vec3d.z;
        double d5 = this.getPosX() + d3;
        double d1 = this.getPosY() + d4;
        double d2 = this.getPosZ() + d0;
        this.world.addParticle(ParticleTypes.HEART, d5 - d3 * 0.25D, d1 - d4 * 0.25D, d2 - d0 * 0.25D, d3, d4, d0);

        System.out.println("DEBUG: arrow tick!");
    }


}

 

[Spawning particles at certain position]

it looks like the particles for the spawner are created in the net.minecraft.world.spawner.AbstractSpawner class. Check out how they do it there, in the tick() method as far as I can tell.

 

Vanilla classes are a good reference for a ton of things

Hey, this is how I'm trying to do it so far. 

    @Override
    public void tick() {
        super.tick();
        this.world.addParticle(ParticleTypes.FLAME, this.getPosX(), this.getPosY(), this.getPosZ(), 0.0, 0.0, 0.0);
        System.out.println("DEBUG: arrow tick");
    }

My full class for my arrow: https://pastebin.com/41jCRgYu

The particle's aren't showing, but the debug message is printing.

Also, I'm not really sure what the particle speed values mean? On AbstractSpawner they're all set to 0 so that's what I did.

Hey in the recent 1.15.2 mdk versions there is also a README.txt which should help you out. Has instructions for IDEA.

[Spawning particles at certain position]

Title says it all, I'd like to spawn some vanilla particles (those fire looking ones from spawners) at a certain coordinate.

This is for adding a visual effect around an arrow as it flies, so I was thinking I could spawn particles at the arrow's coordinate position at every tick.

Hi

 

You don't appear to spawn your entity?

 

Look at BowItem::onPLayerStoppedUsing

Thank you so much, it works now. Guess I missed that while reading through BowItem lol

[Projectile that extends off ArrowEntity not shooting]

You actually don't need to register your arrow since it extends ArrowEntity, which causes Minecraft to treat it as a normal arrow but still execute your custom logic. You do however need to register your custom item. To do that you need to use Registry Events. Here's an example from my mod (This part goes inside your main class):

 

@Mod.EventBusSubscriber(bus=Mod.EventBusSubscriber.Bus.MOD)
    public static class RegistryEvents {
        @SubscribeEvent
        public static void onItemRegistry(final RegistryEvent.Register<Item> event) {
          //This is how you register your Bow. However, in setRegistryName(), your mod should pass your own Mod ID for the first argument, not "minecraft". I'm only doing this in my mod because I'm overriding vanilla Bows. The second argument is whatever you name your custom Bow as. And to receive your Custom Bow you would do /give <your-name> modid:name-of-your-bow
            bow = new ItemForgeBow((new Item.Properties()).maxDamage(384).group(ItemGroup.COMBAT));
        	bow.setRegistryName("minecraft", "bow");
        	event.getRegistry().registerAll(bow);
        }
        
    }

In any case, my mod does work and causes vanilla Bows to fire custom Arrows, so I'm confident that this is all you need for your special Bows to work

 

Hey, I was originally following a tutorial for my mod which registered the bow item like this 

public class RegistryHandler {

    public static final DeferredRegister<Item> ITEMS = new DeferredRegister<>(ForgeRegistries.ITEMS, Megumin.MOD_ID);

    public static void init() {
        ITEMS.register(FMLJavaModLoadingContext.get().getModEventBus());
    }

    // Items
    public static final RegistryObject<Item> STAFF = ITEMS.register("explosion_staff", ExplosionStaff::new);

}

Do i need both of these?

When I inserted your code into my main class along with what i already have (above code), I got this error https://pastebin.com/47ag730Q

The interesting part seems to be this

[23:46:22] [Server-Worker-3/WARN] [ne.mi.re.ForgeRegistry/REGISTRIES]: Registry Item: Override did not have an associated owner object. Name: megumin:explosion_staff Value: air

 

Also, when I delete my registry handler and just use your thing, it's just the same problem as before. The same debug messages print, but no arrow.

[Projectile that extends off ArrowEntity not shooting]

Hey guys, I am trying to make a projectile that extends off of ArrowEntity fire from my item based off of BowEntity. Here is my code for the Bow-based item:

public class ExplosionStaff extends BowItem {
    public ExplosionStaff() {
        super(new Item.Properties().group(ItemGroup.COMBAT));
    }

    @Override
    public void onPlayerStoppedUsing(ItemStack stack, World worldIn, LivingEntity playerIn, int timeLeft) {
        ExplosionSpellEntity spell = new ExplosionSpellEntity(worldIn, playerIn);
        spell.shoot(playerIn, playerIn.rotationPitch, playerIn.rotationYaw, 0.0F, 50.0F, 0.0F);
        System.out.println("Debug: player stopped using staff");
    }

}

 

And here is the code for the arrow-based projectile:

 

public class ExplosionSpellEntity extends ArrowEntity {
    public ExplosionSpellEntity(EntityType<? extends ArrowEntity> type, World worldIn) {
        super(type, worldIn);
    }

    public ExplosionSpellEntity(World worldIn, double x, double y, double z) {
        super(worldIn, x, y, z);
    }

    public ExplosionSpellEntity(World worldIn, LivingEntity shooter) {
        super(worldIn, shooter);
    }

    @Override
    public void shoot(Entity shooter, float pitch, float yaw, float p_184547_4_, float velocity, float inaccuracy) {
        float f = -MathHelper.sin(yaw * ((float)Math.PI / 180F)) * MathHelper.cos(pitch * ((float)Math.PI / 180F));
        float f1 = -MathHelper.sin(pitch * ((float)Math.PI / 180F));
        float f2 = MathHelper.cos(yaw * ((float)Math.PI / 180F)) * MathHelper.cos(pitch * ((float)Math.PI / 180F));
        this.shoot((double)f, (double)f1, (double)f2, velocity, inaccuracy);
        this.setMotion(this.getMotion().add(shooter.getMotion().x, shooter.onGround ? 0.0D : shooter.getMotion().y, shooter.getMotion().z));
        System.out.println("Debug: Shooted!!");
    }

    @Override
    public void onHit(RayTraceResult raytraceResultIn) {
        System.out.println("Debug: spell entity hit");
        this.world.createExplosion(this, this.getPosX(), this.getPosY(), this.getPosZ(), 20, false, Explosion.Mode.BREAK);
    }

}

 

As you can see, I put various debugging messages here. When I let go of the staff item, it displays the "Shooted!!" and "player stopped using staff" messages, but there is no arrow, so the onHit() debug doesn't print.

What do i need to do? I couldn't find any tutorials on how to make projectiles for 1.15.2 so this is just my guess on where to start. I know I have to "register" entities but not sure how to do that. 

Thank you!

See how BowItem creates an arrow and how fireball entity make explosions when collide

To be more specific:

Create and register the entity, maybe make a model and renderer (remember to register it) for it if you dont want it to look like a normal item flying in the sky, and summon it with your item.

 

thank you, will try my best

depend on what kind of "new type of projectile" you want to create, arrow and fireball can be best examples.

Where do i begin making a new type of projectile? I have created an item that extends off of the BowItem class, and I would like it to fire my own type of projectile when onPlayerStoppedUsing.
