Hello World! I'm talking about variables in Alice3.
and I'm going to use a random number.
I have the panda program we worked on earlier
and I've saved it as another name,  and changed the comment to say Panda turn a random amount.

Right now, I have a variable aboutToTurn (that's a double)  has a value of 2.0,
When I run this program the panda turns around 2 full terms.
To make this more interesting, I'm going to pick a random amount.
So where we have 2.0, I'm going to pick random.
and we have a choice of a random number in a range from 0 to 1, or a random number for two different values.

I'm just going to pick a couple numbers for the values,
I picked from .25 to 10
I want to just change that and make that a 2.
and then the panda is going to turn whatever that amount is.
If we run this he turns some amount,  I don't know how much he turned.

I'm going to go back to my panda,
(Let's change the size a little bit.) and have him say how much he's going to turn.
The text string is going to be "I'm turning " 
I'm going to add to that instead of the???, a Double.
The double is going to be amountToTurn.
Now when we run it, he turned his back on us, but I didn't really see what that was.


Let's add a duration to that,  and let him say that for two seconds.
Let's try that again:  he's doing 1.29 something.
Run that again and it's .3 something.
Because it's random each time we run it he turns a different amount.
That random number will stay that value until we give it a new value.

I I'm going to right click on this statement and copy it to the clipboard.
Then take the clipboard and move it down here so get copy of that statement.
He turns first to the left, and I'm going to have him turn exactly the same amount to the right.
so that he spins first one direction and then the other.

I'm going to change this value to a custom decimal number and make that -2.
This is going to be fun.  
He turns to the left and then the right but if he turns to the left a negative amount he's actually turning to the right.
Let's run this.  He's turning a negative amount so he went that direction.
Now it's a positive amount and so he turns in the other direction and back around.
and that's it.
