Hello world! I'm talking about using variables to make it easier to create poses in Alice.

I have a movie with a rabbit.

And I haven't put in scene procedures or anything because I'm just experimenting here and once I get that to work I could use that.

Later for other things.

What I want to do is have the rabbit put both hands on his head.

And.

I know that the shoulder and elbow will both be positioned

In order to do that.

And I want the

Movement to be symmetrical.

In other words the shoulder on the left and the shoulder on the right will move the same amount, and the same with the elbow.

I'm going to start by declaring

A variable.

All of the movement is a double, so I'm going to call this

shoulderAmount.

And give it an initial value of 0.25.

And then I'm also going to create a variable called

elbowAmount which is also a double.

We might as well just make that 0.25

So let's get the hare's right shoulder and let's just see how much we need to do that. I'm going to turn the shoulder.

to the left

The shoulderAmount and run it.

That's not what I want.

Let's try forward, and run it.

Uhh! That's not what I want!

So let's try backwards.

That's what I have in mind.

Now I need to do the elbow and have the elbow turn to put his hand on his head.

So let's get the right elbow and.

I'll also try turning that.

backward.

This time by the elbowAmount, and let's run that.

All right that's not quite enough, he's not touching his head.

So I'm going to make

This

Shoulder move a little bit more and see how that works. So let's change shoulderAmount.

And.

Let's try 0.3.

and run that.

Alright, let's make the elbow turn a little bit more also, custom decimal number 0.3.

Let's run that.

That's exactly what I wanted.

So let's copy that to the clipboard.

Drag that in.

But this time I want this to be the left shoulder, let's just run that.

Alright.

And then we'll.

Copy this to the clipboard.

And change that to the left elbow.

And run it.

And that looks good, but I don't like the way he moves. I'm going to move this all into a

doTogether block and see how that looks.

Run that.

Exactly what I want and now I'm going to have him say something.

Oh my!

And run it one more time.

If I wanted to have him put his arms down.

Copy this to the clipboard.

Drag it in.

And.

Let's just try doing

Forward.

Forward.

Forward for each of those.

And run it.

And that's it.
