Hello world!
I'm talking about functions in Alice3.
I have a scene with a rabbit, a white rabbit.
And a pond.
And I want to make the rabbit fall in the pond.
The first thing I'm going to do
is have the  rabbit turn to face the pond.
And then I'm going to have the rabbit move forward
I'm just going to pick some amount here, .25
But I'm going replace that .25
with a function: and there's a function get distance to.
And we need put in an argument, distance to the pond.
When I run this, the rabbit moves right into the middle of the pond.
With  distance, let's restart that,
The distance between the rabbit and the pond
is the distance between the center point of those objects.
The next thing I'm going to do:
I want the rabbit to just fall straight down into the water.
So, I'm going to go back to procedures
and say move again, and this time I want to move down,
whatever amount, but  this time I'm going to use my functions
to get the height of the rabbit
and replace that .25 with that.
And we run this,
He sinks right down into the pond .
Go back to procedures and have him think
"Help!"
And let's run that again.
And that's it!
