Throwable Items

[ashtonr12]

My throw able dagger works fine no bugs or freezes ecxept you cant see it when its thrown ( the moving entity) it still hits mobs and damages them the items still gets used up just no image.

 

entity class

package ashtonsmod.common;

import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.passive.EntityChicken;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.util.DamageSource;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;

public class EntityThrowingKnife extends EntityThrowable
{
    public EntityThrowingKnife(World par1World)
    {
        super(par1World);
    }

    public EntityThrowingKnife(World par1World, EntityLiving par2EntityLiving)
    {
        super(par1World, par2EntityLiving);
    }

    public EntityThrowingKnife(World par1World, double par2, double par4, double par6)
    {
        super(par1World, par2, par4, par6);
    }

    /**
     * Called when this EntityThrowable hits a block or entity.
     */
    protected void onImpact(MovingObjectPosition par1MovingObjectPosition)
    {
        if (par1MovingObjectPosition.entityHit != null)
        {
            par1MovingObjectPosition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.func_85052_h()), 6);
        }

        if (!this.worldObj.isRemote && this.rand.nextInt( == 0)
        {
            byte var2 = 0;

            if (this.rand.nextInt(32) == 0)
            {
                var2 = 0;
            }

        if (!this.worldObj.isRemote)
        {
            this.setDead();
        }
    }
}}

 

Dagger class

package ashtonsmod.common;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.EnumRarity;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class Dagger extends Item{


    public Dagger(int par1)
    {
        super(par1);
        this.maxStackSize = 64;
    }
    
    public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
    {
        if (!par3EntityPlayer.capabilities.isCreativeMode)
        {
            --par1ItemStack.stackSize;
        }

        par2World.playSoundAtEntity(par3EntityPlayer, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

        if (!par2World.isRemote)
        {
            par2World.spawnEntityInWorld(new EntityThrowingKnife(par2World, par3EntityPlayer));
        }

        return par1ItemStack;
    }
    @Override
  	public String getTextureFile(){
  		return CommonProxy.items_png;   
}

   }

[mnn]

you have to implement and register a renderer. look at RenderingRegistry.registerEntityRenderingHandler .

[ashtonr12]

thanks for the hint, i got this far.

 

public void renderRegistry() 
        {
             RenderingRegistry.registerEntityRenderingHandler(EntityThrowingKnife.class, new RenderEntityThrowingKnife.class);
        }

 

there is an error after new that spans to the .class and i cant see to fix it all the other constructors and classes are in place, just this one part

[mnn]

only on client proxy register rendering stuff, server doesn't need to know.

[ashtonr12]

ok so it works now but the entity looks like a white cube and it goes through walls

[ashtonr12]

Let me know if you want to look at any classes

[mnn]

well, you have to implement your custom renderer, because the vanilla ones work only for vanilla stuff (at least the snowball does). if you want just slightly modified snowball renderer you can take a look at this - https://github.com/mnn/jaffas/blob/c5359edb2e287d6503ec8a4def73b01917c4b257/src/minecraft/monnef/jaffas/food/client/RenderItemInAir.java.

I'm afraid you have lost me sorry.

 

I currently have;

 

An Item that fires an entity'

package ashtonsmod.common;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.EnumRarity;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class Dagger extends Item{


    public Dagger(int par1)
    {
        super(par1);
        this.maxStackSize = 64;
    }
    
    public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
    {
        if (!par3EntityPlayer.capabilities.isCreativeMode)
        {
            --par1ItemStack.stackSize;
        }

        par2World.playSoundAtEntity(par3EntityPlayer, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

        if (!par2World.isRemote)
        {
            par2World.spawnEntityInWorld(new EntityThrowingKnife(par2World, par3EntityPlayer));
        }

        return par1ItemStack;
    }
    @Override
  	public String getTextureFile(){
  		return CommonProxy.items_png;   
}

   }

 

An Entity for the item to fire'

package ashtonsmod.common;

import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.monster.EntityBlaze;
import net.minecraft.entity.passive.EntityChicken;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.util.DamageSource;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;

public class EntityThrowingKnife extends EntityThrowable
{
    private static final EntityPlayer shootingEntity = null;

public EntityThrowingKnife(World par1World)
    {
        super(par1World);
    }

    public EntityThrowingKnife(World par1World, EntityLiving par2EntityLiving)
    {
        super(par1World, par2EntityLiving);
    }

    public EntityThrowingKnife(World par1World, double par2, double par4, double par6)
    {
        super(par1World, par2, par4, par6);
    }

    /**
     * Called when this EntityThrowable hits a block or entity.
     */
    protected void onImpact(MovingObjectPosition par1MovingObjectPosition)
    {
        if (par1MovingObjectPosition.entityHit != null)
        {
            par1MovingObjectPosition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.func_85052_h()), 6);
        }

        if (!this.worldObj.isRemote && this.rand.nextInt( == 0)
        {
            byte var2 = 1;

            if (this.rand.nextInt(32) == 0)
            {
                var2 = 4;
            }

        }

        if (!this.worldObj.isRemote)
        {
            this.setDead();
        }
    }
}

 

A preintit method for the entity

@PreInit
public void registerMyEvents(FMLPreInitializationEvent e){
    {
        EntityRegistry.registerModEntity(EntityThrowingKnife.class, "Throwing Knife", 1, this, 250, 5, true);
    }

 

and finally a render hook/thing in the client proxy'

  public void renderRegistry() 
        {
             RenderingRegistry.registerEntityRenderingHandler(EntityThrowingKnife.class,  RenderEntityThrowingKnife());
        }

	private Render RenderEntityThrowingKnife() {
		return null;
	}
        

 

As it stands;

-My item fires the entity from the top right of my player entities face.

- the entity fired appears as a white cube in game.

-the entity goes through all blocks/walls/floors.

 

If you could instruct me or guide to a tutorial or something to help me fix the above problems i would be immensely grateful.

Thankyou.
