Hello World!
I'm talking about click events in Alice3.
I'm continuing with this movie where we have a bear,
an elk and three trees.

At this point when we click on the bear he says, "What can I do for you?"
and if we click anywhere else nothing happens.
Nothing happens when we go there.

If this statement is false, and it's not the bear,
it  could be any one of the other objects:  the elk or one of the three trees.
I'm going to put an if control structure inside this else block.
I'm  going to replace the true and compare two SThings.
The first one is the elk,  the second one is also the elk.
Then I'm going to replace one of these with 
that function that tells us what item was clicked.

I can't just put something for the elk to say as the else,
I have to have another if, and check if it wasn't the bear cub, 
was the elk equal to the thing that was clicked?
Then I'm going to have the elk say "What??"

Let's run that and if I click anywhere else,
If  I click on one of the trees nothing happens.
Actually the trees are the only thing that's left.
If we click one of the trees we don't know which one was clicked.
I'm going to pick the middle one and have the middle and say, 
"We are trees",  so it sounds like all three of them are talking

Let's try that.
And that's it!
