1_ As you have named layouts as (1,2,3,...) I use the name of the layout to know in which level I am.
The int() is a system expression that turns a string into a number, as the X coordinate expected in an array is a number.
2_ Check the how do I FAQ in the "Arrays" section, I did a capx a while ago that pretty much explains everything, and check also the manual entry about arrays.
10 is a default value, in the end, the width (X) of your array will have to be your total number of levels.
really good works thanks man, but i need to know one more thing
if my layouts name liked this : Layout (1-10) for example Layout 1
will this int(LayoutName) change or it will be the same??
thanks for the array helps ^^ till now i didn't understand them but im going to focus on them later :) ill see your .capx.
*by the way i have read array manual seems they are hard to understand...
