I was just reading the Physics manual (http://download.clickteam.com/tutorials/en/quick-physics.pdf) and on page 7 it talks about adding a Quick Backdrop and resizing it to make it the ground. Then you right-click on it (the Quick Backdrop) and Create > Active Object, and delete the Quick Backdrop object. Why not just create and Active Object as the ground in the first place? Why the (seemingly) unnecessary steps?
Also I have read the help documentation and I still don't quite understand the difference between a Quick Backdrop and a Backdrop and when I should use one over the other. Any help would be appreciated.
PS: On this note, I have the Getting Started w CTF 2.5 book, watched most, if not all of the tutorials for CTF 2.5 on youtube and, while helpful, I cannot find anything that explains the "why" of using one object type, movements, etc... over another. In other words, most are just saying "Ok, add this object, make it a _____, and now lets go to the event editor and..... Is there any resource that really goes into the "whys" so a person like me can understand the concepts?
