Answering the questions.
1. Yes, there will be an animation of the text counter A up to the maximum value of text B. However, later text B can be changed, so I need the percentage of the bar to be changed as the total text B changes.
2. Yes, when the A text counter reaches maximum, it must fill 100% of the bar
3. In this case, I used a rectangle shape with a 100% width scale. But it need not be necessarily that way, if I hear an easier way I accept it.
Thanks for the quick service, and sorry for the google translator
