Hello World!
I'm talking about arrays in Alice3.
I'm  going to use an array
to find which one of my characters is the tallest.
I have four people in my scene
and I'm going to make an array of them.
So I will pick gallery class
and pick SJointedModel that's able to say and also
get height  for that.
Those of the two things we want to be able to do
so that's the one I'm going to pick and then say OK.
and let's call this actors,
Check array and add each one of them to the array.
When we want to find the largest value, or the smallest
from an array,
we usually start by just taking the first one and assuming
that that's the tallest.
I'm going to create a variable that is going to be
the same type: SJointedModel
And set ogre to the tallest.
Then I'm going to compare each one to tallest.
If  ogre is taller than tallest,
then I will set tallest to ogre.
and I'll compare Thor, and if he is taller than tallest,
I'll set tallest to Thor.
and so on through the array.
So let's get a variable
and it's going to be SJointedModel
I'm going to call this tallest
and initialize it to actors sub zero ( actors[0])
And  set array.
Next I need to use a use a
I could either use a count loop or I could use a
for each and it's going to be a gallery class.
Pick  that same line,
and let's call this one person.
Were going to be using the array actors.
So person is going to be Odin, then person is going to be the ogre and so on.
Now, I should have person here.
and so I can now refer to person as I need to.
So what I want to do is call compare
the person's height to the tallest and if,
I'm going to be comparing decimal numbers.
(I'm going to make this a little smaller so we can see everything.)
So I'm going to compare
decimal numbers and decimal number
becasue it's not comparing Oden to the ogre,
it's comparing Oden's height to the ogre's height.
So decimal numbers and if it's greater than
and I just need to pick two values
as placeholders and then I can
compare that, let's just put this back over.
So this one is going to be the person
and get height of that person.
and if person's height is greater than the tallest getHeight
then I need an assignment statement
that says tallest equals
person, the person that I'm comparing.
and when I get all finished,
we'll have one of them is going to be tallest.
and I'm going to have tallest say
" I'm the tallest."
and if we run it
we see the ogre says  "I'm the tallest."
but we don't really have a clue
what that was all about
So it's just a little trace in here
so that we can just see what's happening.
I'm going to have each one say how tall they are.
and custom text string is going to be "My height is "
with a space after that and then we're going to
+ ??? something that's going to be a double.
and just pick any value as a placeholder
and then instead of that the
person's height, just slide that in there.
and now each person is going to say there height
We time to read that, so I'm going to just set the duration to 2.
We run 1.9, 1.99, 1.8 1.58
Ogre says, "I'm the tallest" and that's true he is.
If you want you can just disable that, we did that for testing.
and that's okay,  you can leave it in if you want.
Can you find the smallest, the shortest?
That would be a nice experiment to try.
