Slide variable for transparency and space for background changing. The background is to test how transparent the dot is by setting to different colors.
For @TheLogFather When I knew about pen transparency, I noticed that the alpha, the parameter for transparency was multiplied by 16777216. However, here I have a variable multiplied by 16777216. As the number increases, it is first transparent, then it turns into a translucent color as the variable becomes 100. I think this is something implemented in the Scratch engine. What do YOU think?
