I am new to Minecraft moding but not to coding or java. I just sat down and created a custom tnt mod and I copied the `EntityTNTPrimed.java`to do a custom explosion but when the block is activated and my `EntityNuclearTntPrimed` gets created it is invisible. Any help would be appreciated.

You should set up your own entity model.

You should set up your own entity model.

 

Here is my code:

1. Post your entity registration code.

2. Did you created/registered your TNT model?

My Tnt Block Code:

 

 

public class NuclearTntBlock extends BlockTNT 
{

public NuclearTntBlock () 
    {
	super();
	setHardness(2.0F);
	setStepSound(Block.soundTypeMetal);
        setUnlocalizedName("nuclearTnt");
        setCreativeTab(CreativeTabs.tabRedstone);
    }

@Override
    public void onBlockDestroyedByExplosion(World worldIn, BlockPos pos, Explosion explosionIn)
    {
        if (!worldIn.isRemote)
        {
            EntityNuclearTntPrimed entitytntprimed = new EntityNuclearTntPrimed(worldIn, (double)((float)pos.getX() + 0.5F), (double)((float)pos.getY() + 0.5F), (double)((float)pos.getZ() + 0.5F), explosionIn.getExplosivePlacedBy());
            entitytntprimed.fuse = worldIn.rand.nextInt(entitytntprimed.fuse / 4) + entitytntprimed.fuse / 8;
            worldIn.spawnEntityInWorld(entitytntprimed);
        }
    }

@Override
    public void explode(World worldIn, BlockPos pos, IBlockState state, EntityLivingBase igniter)
    {
        if (!worldIn.isRemote)
        {
            if (((Boolean)state.getValue(EXPLODE)).booleanValue())
            {
                EntityNuclearTntPrimed entitytntprimed = new EntityNuclearTntPrimed(worldIn, (double)((float)pos.getX() + 0.5F), (double)((float)pos.getY() + 0.5F), (double)((float)pos.getZ() + 0.5F), igniter);
                worldIn.spawnEntityInWorld(entitytntprimed);
                worldIn.playSoundAtEntity(entitytntprimed, "game.tnt.primed", 1.0F, 1.0F);
            }
        }
    }
}

 

 

 

My Mod Code:

        final int DEFAULT_ITEM_SUBTYPE = 0;
        Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(itemBlock, DEFAULT_ITEM_SUBTYPE, itemModelResourceLocation);
        
        IRecipe nuclearTntRecipe = new ShapedOreRecipe(new ItemStack(nuclearTnt), new Object[] {
            "TTT",
            "TTT",
            "TTT",
            'T', Blocks.tnt,
    });
    GameRegistry.addRecipe(nuclearTntRecipe);
    }
    
    public static LargeExplosion createLargeExplosion(World inWorld, Entity p_72876_1_, double p_72876_2_, double p_72876_4_, double p_72876_6_, float p_72876_8_, boolean p_72876_9_)
    {
        return UberTntMod.newLargeExplosion(inWorld, p_72876_1_, p_72876_2_, p_72876_4_, p_72876_6_, p_72876_8_, true, p_72876_9_);
    }
    
    public static LargeExplosion createLargeExplosion(World inWorld, Entity p_72876_1_, double p_72876_2_, double p_72876_4_, double p_72876_6_, float p_72876_8_, boolean p_72876_9_, boolean p_72876_10_)
    {
        return UberTntMod.newLargeExplosion(inWorld, p_72876_1_, p_72876_2_, p_72876_4_, p_72876_6_, p_72876_8_, p_72876_9_, p_72876_10_);

    	if (net.minecraftforge.event.ForgeEventFactory.onExplosionStart(inWorld, explosion.vanillaExplosion)) return explosion;
    	explosion.doLargeExplosionA();
    	explosion.doLargeExplosionB(true);

}

 

 

How do you register non `TitleEntity` `Entities`?

I tried adding:

int entityID = EntityRegistry.findGlobalUniqueEntityId();
EntityRegistry.registerGlobalEntityID(EntityNuclearTntPrimed.class, "nuclearTntPrimed", entityID);

 

but it did not help

1. First, you should register your Entity using EntityRegistry#registerModEntity.

      (You have to specify the id. If you have only one entity, just putting 0 in it would be fine.)

2. TileEntities and Entities are totally different, just to note.

To change texture of tnt, you need to overhandle renderer of this entity. In client proxy in init section, register custom entity renderer. Than do what you what in it.

Show your tnt entity class. I had the same problem and had to change something in the entity class

 

EDIT:

The entity tnt class has 2 constructors, you need to write this.fuse = whatever number the other one is in the first constructor to.

 

 

Here is my tnt Entity Code:

 

 

import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.util.EnumParticleTypes;
import net.minecraft.world.World;

public class EntityNuclearTntPrimed extends Entity
{
    public int fuse;
    private EntityLivingBase tntPlacedBy;

    public EntityNuclearTntPrimed(World worldIn)
    {
        super(worldIn);
        this.preventEntitySpawning = true;
        this.setSize(0.98F, 0.98F);
    }

    public EntityNuclearTntPrimed(World worldIn, double p_i1730_2_, double p_i1730_4_, double p_i1730_6_, EntityLivingBase p_i1730_8_)
    {
        this(worldIn);
        this.setPosition(p_i1730_2_, p_i1730_4_, p_i1730_6_);
        float f = (float)(Math.random() * Math.PI * 2.0D);
        this.motionX = (double)(-((float)Math.sin((double)f)) * 0.02F);
        this.motionY = 0.20000000298023224D;
        this.motionZ = (double)(-((float)Math.cos((double)f)) * 0.02F);
        this.fuse = 80;
        this.prevPosX = p_i1730_2_;
        this.prevPosY = p_i1730_4_;
        this.prevPosZ = p_i1730_6_;
        this.tntPlacedBy = p_i1730_8_;
    }

    protected void entityInit() {}

    protected boolean canTriggerWalking()
    {
        return false;
    }

    public boolean canBeCollidedWith()
    {
        return !this.isDead;
    }

    public void onUpdate()
    {
        this.prevPosX = this.posX;
        this.prevPosY = this.posY;
        this.prevPosZ = this.posZ;
        this.motionY -= 0.03999999910593033D;
        this.moveEntity(this.motionX, this.motionY, this.motionZ);
        this.motionX *= 0.9800000190734863D;
        this.motionY *= 0.9800000190734863D;
        this.motionZ *= 0.9800000190734863D;

        if (this.onGround)
        {
            this.motionX *= 0.699999988079071D;
            this.motionZ *= 0.699999988079071D;
            this.motionY *= -0.5D;
        }

        if (this.fuse-- <= 0)
        {
            this.setDead();

            if (!this.worldObj.isRemote)
            {
                this.explode();
            }
        }
        else
        {
            this.handleWaterMovement();
            this.worldObj.spawnParticle(EnumParticleTypes.SMOKE_NORMAL, this.posX, this.posY + 0.5D, this.posZ, 0.0D, 0.0D, 0.0D, new int[0]);
        }
    }

    private void explode()
    {
        float size = 50.0F;
        UberTntMod.createLargeExplosion(this.worldObj, this, this.posX, this.posY + (double)(this.height / 2.0F), this.posZ, size, true, true);
    }

    protected void writeEntityToNBT(NBTTagCompound tagCompound)
    {
        tagCompound.setByte("Fuse", (byte)this.fuse);
    }

    protected void readEntityFromNBT(NBTTagCompound tagCompund)
    {
        this.fuse = tagCompund.getByte("Fuse");
    }

    public EntityLivingBase getTntPlacedBy()
    {
        return this.tntPlacedBy;
    }

    public float getEyeHeight()
    {
        return 0.0F;
    }
}

 

 

Just write this.fuse = 80 in the first constructor and it should work

It (the fuse field) is not related with this issue...

Anyway you should register custom entity renderer, as elix said.

It probably isn't... But that's what made mine work

Anyway it seems that he didn't set up custom entity renderer.

Oh well if that's the case the fuse thing probably won't work either...

Okay so a custom Entity Renderer like this? :

 

 

public class RenderEntityNuclearTntPrimed extends RenderEntity {

private static final ResourceLocation textureLocation = new ResourceLocation(UberTntMod.MODID + ":" + "textures/models/entityTest.png");

public RenderEntityNuclearTntPrimed(RenderManager manager) {
	super(manager);
}

@Override
protected ResourceLocation getEntityTexture(Entity par1Entity)
{
	return textureLocation;
}

}

 

 

 

And if so how do I get it to deal with the fact that my entity texture has custom top, bottom, side or should I join them into one file just for this entity I looked through the mc textures and saw no place where they did that though for normal tnt.

 

Try using Techne. It would answer your questions and solve most of your problems.

Take look at RenderTNTPrimed.class. It is renderer class that renderers EntityTNTPrimed. It will answer most of your questions

How do you add the renderer to the entity?

Shouldn't your EntityNuclearTntPrimed extend EntityTntPrimed?

Don't just go to some random post from 2015 to give 'help'
