I would like to add projectiles that have knockback. Unfortunately, I don't know how to add knockback to projectiles. When I try it only knocks mobs back when I aim at the positive coords but when I don't it sends them upwards. How do I fix this?

 

 

 

[package mymod.projectiles;

 

import net.minecraft.entity.EntityLivingBase;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.entity.projectile.EntityThrowable;

import net.minecraft.util.MathHelper;

import net.minecraft.util.MovingObjectPosition;

import net.minecraft.world.World;

 

public class MyEntityPushProjectile extends EntityThrowable

{

    private float test;

 

public MyEntityPushProjectile(World par1World)

    {

        super(par1World);

    }

 

    public MyEntityPushProjectile(World par1World, EntityLivingBase par2EntityLivingBase)

    {

        super(par1World, par2EntityLivingBase);

    }

 

    public MyEntityPushProjectile(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)

        {

            byte b0 = 5;

           

           

           

            par1MovingObjectPosition.entityHit.addVelocity(this.motionX * 1.6000000238418579D, this.motionZ * 1.6000000238418579D, entityCollisionReduction);

   

        }

 

 

 

        if (!this.worldObj.isRemote)

        {

       

            this.setDead();

 

           

        }

    }

 

}

]

Thanks a ton! I fixed it by adding a MotionY into it like you said and it worked.
