There is a very stupid way to do that. And I'm sure there is a VERY much better way to do it. But making 10 pictures, each getting more filled, like the exaple below.
---------- picture 1
0---------
00--------
000-------
0000------
00000-----
000000----
0000000---
00000000--
000000000-
0000000000 all the way to picture 10
and when yo get to a certain point in a variable (say 10), you change the picture to picture 2. Which has 10% filled.
As I said, this is a very, very, VERY stupid way to make this. And I'm sure there is a better way to do this.
And your last point... Is there absolutely NO way to describe what you mean? An accurate explanation of your problem(s) might make people understand your meaning. 'cause I really don't, I'm just guessing.
