so i'm trying to make an custom arrow i'm in the registering part now but can't seem to figure out how it works.

my item:

package com.CloudyProductions.DreamMod.heaven.items;

import com.CloudyProductions.DreamMod.Main;
import com.CloudyProductions.DreamMod.init.ItemInit;
import com.CloudyProductions.DreamMod.util.IHasModel;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.projectile.EntityArrow;
import net.minecraft.item.ItemArrow;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class CloudArrow extends ItemArrow implements IHasModel {

    public CloudArrow(String name, CreativeTabs tab) {
        setUnlocalizedName(name);
        setRegistryName(name);
        setCreativeTab(tab);
        setMaxStackSize(64);

        ItemInit.ITEMS.add(this);
    }
    public EntityArrow makeTippedArrow(World world, ItemStack itemstack, EntityLivingBase shooter) {
        return new com.CloudyProductions.DreamMod.heaven.entitys.CloudArrow(world, shooter);
    }
    @Override
    public void registerModels() {
        Main.proxy.registerItemRendere(this, 0, "inventory");
    }

}

the arrow entity:

package com.CloudyProductions.DreamMod.heaven.entitys;

import com.CloudyProductions.DreamMod.init.ItemInit;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.projectile.EntityArrow;
import net.minecraft.item.ItemStack;
import net.minecraft.util.EnumParticleTypes;
import net.minecraft.world.World;

public class CloudArrow extends EntityArrow {

    public CloudArrow(World worldIn) {
        super(worldIn);
    }
    public CloudArrow(World worldIn, EntityLivingBase shooter) {
        super(worldIn, shooter);
    }
    @Override
    public void onUpdate() {
        super.onUpdate();
        if (this.world.isRemote && !this.inGround) {
            this.world.spawnParticle(EnumParticleTypes.CLOUD, this.posX, this.posY, this.posZ, 0.0D, 0.0D, 0.0D, new int[0]);
        }
    }
    @Override
    public ItemStack getArrowStack() {
        return new ItemStack(ItemInit.CLOUD_ARROW);
    }
    @Override
    public void arrowHit(EntityLivingBase living) {
        super.arrowHit(living);
        if (living != shootingEntity) {
            world.createExplosion(shootingEntity, living.posX, living.posY, living.posZ, 4.0F, true);
        }
    }
}

the render entity:

package com.CloudyProductions.DreamMod.heaven.entitys;

import com.CloudyProductions.DreamMod.Reference;
import com.CloudyProductions.DreamMod.heaven.items.Cloud;
import net.minecraft.client.renderer.entity.RenderArrow;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

@SideOnly(Side.CLIENT)
public class RenderCloudArrow extends RenderArrow<CloudArrow> {

    public static final ResourceLocation res = new ResourceLocation(Reference.MODID, "textures/entitys/cloud_arrow.png");

    public RenderCloudArrow(RenderManager rm) {
        super(rm);
    }
    @Override
    public ResourceLocation getEntityTexture(CloudArrow entity) {
        return res;
    }
}

but how can i register this

trying to do this 

EntityRegistry.registerModEntity(CloudArrow.class, new RenderCloudArrow());

but i need and RenderManager

and how do i use this code please

if you can give me the code

i did it and it came sort of cool out when you shoot the arrow it disappears from you're inventory when you pic it up it changes to an normal arrow
