I was mostly confused on what At( ) meant in XAt( ).
The Manual refereed to "At" Expression as Absolute and I didn't realize "At" meant Absolute.
I looked it up on the Touch Page of the Manual because of Lamar.
It makes me assume Touch.X would be relative if a layer was rotated, I didn't even think of that possibility until then.
I was only familiar with Abs() as Absolute.
Abs() of course makes any value positive.
abs( 5 - 10) will return 5 instead of -5
-Abs() will make any value negative.
-abs( 10 - 5) will return -5 instead of 5
It is used to keep any math in the abs() expression to always have positive or negative results.
These are of course different Absolutes, just tossing it in to help some readers.
I only tried to find/search for "XAt".
I thought trying to search for At would have been difficult, since it is a common word.
I missed the quote below, because it was under AbsoluteX in the manual.
"The At expressions can return the absolute position of any touch given its zero-based index, and the ForID expressions return the position of a touch with a specific ID."
Some Examples for the above Quote:
After finding Absolute in the Manual, I read the At expression returned the Absolute position.
I then noticed this.
What is the need for Absolute if At expression does Absolute?
Does AbsoluteX do the same as XAt?
