I'm trying to update an old mod's code to work in a new 1.7 mod... but I have no idea what the new code is

package assests.jordsta95;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;
import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.util.DamageSource;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;

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

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

    @SideOnly(Side.CLIENT)
    public EntitySafePearl(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.getThrower()), 0);
        }

        for (int var2 = 0; var2 < 32; ++var2)
        {
            this.worldObj.spawnParticle("portal", this.posX, this.posY + this.rand.nextDouble() * 2.0D, this.posZ, this.rand.nextGaussian(), 0.0D, this.rand.nextGaussian());
        }

        if (!this.worldObj.isRemote)
        {
            if (this.getThrower() != null && this.getThrower() instanceof EntityPlayerMP)
            {
                EntityPlayerMP var3 = (EntityPlayerMP)this.getThrower();

                if (!var3.playerNetServerHandler.connectionClosed && var3.worldObj == this.worldObj)
                {
                    this.getThrower().setPositionAndUpdate(this.posX, this.posY, this.posZ);
                    this.getThrower().fallDistance = 0.0F;
                }
            }

            this.setDead();
        }
    }
}

The line which is giving me issues is:

  if (!var3.playerNetServerHandler.connectionClosed && var3.worldObj == this.worldObj)

more specifically the .connectionClosed.

I tried replacing it with everything that was recommended (in Eclipse) and none of them worked. Any ideas?

 

As you seem to have copied the code from

EntityEnderPearl

, I looked in the

onImpact

method in

EntityEnderPearl

, and I found this:

if (entityplayermp.playerNetServerHandler.func_147362_b().isChannelOpen() && entityplayermp.worldObj == this.worldObj)
