Trying to apply motion to Player 1.12

[Blaez]

I'm Trying to apply a Similar Effect to the Code below Where by on hit of an entity the player is bounced backwards in the opposite direction the player is facing.

Although the below code is for 1.7.2 so its not of much use as reference I figured it would help convey the point. 

public boolean hitEntity(ItemStack par1ItemStack, EntityLivingBase par2EntityLivingBase, EntityLivingBase par3EntityLivingBase)
    {
        Entity entity =  par3EntityLivingBase;

        Vec3 look = par3EntityLivingBase.getLookVec();


        par3EntityLivingBase.motionX = look.xCoord ;
        par3EntityLivingBase.motionZ = look.zCoord ;
        par3EntityLivingBase.motionY = look.yCoord ;
        par3EntityLivingBase.lastTickPosZ = look.xCoord;
        par3EntityLivingBase.lastTickPosX = look.zCoord;


        set_Item_State(par1ItemStack, false);
        par1ItemStack.damageItem(1, par3EntityLivingBase);
        return true;
    }

Okay. So do you have a problem or something? What isn't working?

I'm more so asking how to go about do it as you can no longer use getlookvec with Entityliving or Player Classes

You can still get a look vector. They just renamed the method to getLook(). You can figure this out yourself (i.e. when something changes between versions) but looking at the type hierarchy for the class and seeing of any of the methods have a name that suggest it is equivalent behavior.
