Hello world!
I'm talking about counters in Alice3.
I have a scene set up with the tiger
and I want the tiger to count.
I'm going to use a variable
If we count 1, 2, 3 that's going to be and integer.
Let's name it counter
and give it an initial value of zero.
I'm going to use a while loop
This is going to go on forever and ever ,
and then an assignment statement
that is going to be counter=counter
and a little math:  counter +1
counter is currently zero,  when this statement executes
we're  going to take the current value of counter
at 1 to it and assign that as the new value for counter.
and then I'm going to have the tiger say that number.
So for the text part I'm just going to say zero,
I mean nothing, and then plus
an integer and that integer is going to be the counter.
When we run this
he says 1, 2, 3 and
this will just go on forever and ever.
and each time this is executing
he's taking the current value of counter,
adding  one to it, and then he says that number.
It might be fun to have him jump while he counts.
or do something like that,
but that's the whole thing about counter.
