I'm looking for tutorial or something to explain methods of finding 'object manager' or 'arrays of objects' (class/structures). I've read somewhere about TLS method but I can't find much info about it or how use it in practice. Also I'm stuck with one my projects. I could easily find objects like Player structure in memory but can't find the start of array of objects. Another question, how to find the size of structure? Is there some quick method? What when objects structures have different length in memory, how to catch them so I can iterate through game objects?

EDIT:
For example, I've discovered in a structure of object a field where address of next object in list of objects is stored. So how do I find the first object in list.
