Now though we took a look at what an empty is.
Let's take a look at something else and we will see how the empty works in relation to that.
So in this video when you look at parent child relationship with Blendr now parent child relation sounds
it does as it sounds it sets up a parent and a child object and the child object basically copies the
parent object.
So to show you it's much easier.
So let's go ahead and do that.
Let's hit alt H.
And unhide everything.
And this way we will see what our empty does as well and how it's used.
So if I select my ball right here you can see that if I select the empty in the middle and move it or
rotate it nothing's happening it's just kind of rotating itself.
Now the ball is independent as well.
But if I select the ball and then shift select the empty.
So you have to select the ball first and then the empty not the other way around.
Otherwise it will have a different result.
Because now for a child parent relationship it basically works like this.
The first object that you select will be the child.
And the second object you select will be the parent.
So if we select the ball then the empty by holding Shift right clicking and then control P. You can
see that says set parent to object and just select object right there.
Now the ball is the child and the empty right here is the parent.
So if we select the empty you can see that if we move it rotate it or do anything with it.
The ball will copy the empty because it the ball is the child and the empty is the parent.
So anything we do with the empty the ball will follow along.
So that's pretty cool.
And this is a great way and you could still move the ball independently from the empty.
But when you move the empty the ball follows.
Now you don't want to move the ball independently from the empty in this example but you could see that
if I do you will see this dotted line from the ball all the way to the empty right here showing that
the ball is a child to the parent of the empty.
Pretty cool.
So what this allows for us to do is just have because now we're also going to select the lattice by
right clicking it and then shift selecting the empty and then hitting control P and setting the parent
to the empty with the lattice as well.
Now if we select the empty you can see that if we grab it and move it it will move both the lattice
and the ball because they are both child of the empty as you can see via these lines right here.
They are both Parenthood to the empty that we have right here.
Now let me undo that.
Make sure they're still there.
And so what this allows for us to do is basically move one single object and at the same time it moves.
Both of these otherwise we would have to animate all we would have to animate the ball and the lattice
in the same movement.
For example if we want the ball to move this way then we'd have to move the lattice as well and it's
much easier this way.
This way you only have to focus on empty and you animate the empty.
And it will animate both of them for you and they will follow the empty.
So that is parent child relationship.
Are the it's very very useful and to clear a parent child relationship.
All you do is select your objects for example the sphere and then the lattice and that are Asare the
empty and hit alt P and clear parent.
Now if I select the empty you can see that the ball is no longer parents add to it.
Let's go ahead and parents it back by selecting the ball shift right clicking into empty control P and
said the parent object.
And there we have it.
So for our animation we're going to be animating the empty right here and it's going to affect both
the ball and the lattice.
All right.
I'll see you in the next video.
All right.
Here's one of my favorites.
I'm just kidding they're all my favorites like a flowing river like a rushing wind.
Your essence never changes yet is never the same.
Don't try to hold onto the old break away from the chains of your past.
You knew that they could never last.
It is finally time.
Spread the wings of your mind embrace faith leap and take flight and you'll find the freedom is your
birthright.
I ladies and gentlemen let go of the past and move on to something better.
Keep on blenny my friends.
I'll see you in the next video and keep rocking it.
All right.
Ciao for now.
