- [Instructor] This is video

is an exercise video or assignment video.

I invite you to create two new animation

using the bouncing ball and this parkour object.

The idea is to launch the bouncing ball onto the surface.

I've made two version of the animation,

one with a very heavy bouncing ball,

like a bowling ball

that will strike the surface

and almost stop and then will be rolling.

And the second animation

with a more squashy and light bouncing ball

that will just bounce until it stops.

You can find those two animation

in the action library.

I will explain you right now the key component

of those animation

and the next video will be a time lapse

of me creating those two animations.

It's exactly the same workflow

as on the previous animation.

And I will just double the speed

of the video so that you can use VLC Player,

for example, to slow down the video

by 50% and get it real time if you need.

On the squashy bouncing ball animation,

instead of moving the screen controller

to give an orientation to the ball,

you can also rotate its root controller

and use the squash and stretch controller only

to squash and stretch the ball currently.

So only on their z-axis.

The thing you will have to check out

during your polishing is the amplitude

of the squash and stretch curve.

As you go down the parkour,

the ball will lose energy

and so the squash and stretch will get more subtle

and more subtle as you reach the end of the animation.

So your curve must lose amplitude.

For the heavy ball animation,

I haven't used squash and stretch at all.

To make the ball feels heavy,

I've used very subtle bouncing

and very short bouncing.

The key point here is to remove the squash and stretch

or make it very subtle

and make the bounce very small

and you will get this feel of weight in the ball.

The second very important thing

to watch out on this animation is the spacing of the ball.

It gets bigger and bigger

as the ball is falling toward the first surface.

Due to its weight, the ball almost stop

when it hits the surface

as we are close to 90-degree angle

and then the ball is accelerating until it touch the ground

and then it will slowly lose speed

as soon as the animation go ahead until it stops.

The longer time it takes to stop,

the heavier it will feel.

You now have all the instruction

to create those animation.

The next video is the time lapse

of me creating those two animations

and then we will start working

on our first character animation.
