Hi, I'm working on a modification in which I need to use multi-block structures.
For example, each such structure should have one common interface, consist of one kind of blocks, have logic by which all sorts of things happen inside the structure, be dynamically expandable or diminish, have the form of a box with a size limit and so on...
So, where I need to look for information on such structures. What I need to use, what are the possible pitfalls in creating such structures.
P.s.: under the phrase "where I need to look for information" I mean source files, not Google)
