GetCreatureNumber(unitName);
.

Well... for example, I put a hero on a map, changed his shared data, and now he looks like a druid. If I upload this map to the internet, will he look the same there too?

And also - if I then create a new map and put this hero on it, he looks normal again, but when I launch the game, he still turns into a druid.

I would write it using auxiliary values. For example, at the very beginning of the map, I would set
a = 0;

In the second trigger, I would add a check
if a == 1 then
Your function
Trigger reset
else
if a == 0 then
Text: you have not visited the first hut
end;
end;

And in the first hut, write your function, and at the end add
a = 1;

If it's not clear, I can write a detailed template later.

1. 'a' is a variable. If you write 'b', you need to replace all instances of 'a' with 'b'.
2. Add sleep(10) between the dialogue and the message.

Here's an example of how it can be used:

function DefenderCreatureMove(Unit)
  if GetCreatureType(Unit)==CREATURE_SNOW_APE then
    SummonCreature(DEFENDER, 54, GetCreatureNumber(Unit), 13,8);
  end;
end;

What will happen: each time it's an enemy's turn and a Yeti is present, a number of creatures with ID 54 will be summoned, equal to the number of Yetis in the stack. It looks a bit unconventional for a scripting language, but it works.
