That is a very good question indeed, and although I didn't directly spot this I am fixing it by making an inventory class with all the functions for manipulation in so that if a Mob does need an inventory it can inherit, if it doesn't the it won't have the inventory and also will not have functions wasting memory and that could also be potentially dangerous if called.
Thanks for pointing that out though, I will have a scan through to make sure I don have anything else like this.
@L B Thanks for correcting stonedbear that he wasn't really getting the question but there was no need to be insulting (although it was only minor)
@stonedbear I didn't mention at all about using integer variables or macros but you even quotedmy question
how do I find "size1" and "size2" individually?
... I do hope you know the definition of the word "find"... And I was using "size1" and "size2" to reference the variables I wish to find for clarity, most understood this easily.
Also I am very greatful that LB pointed out that design flaw, it seems obvious when said but it can be difficult to notice some things like this (probably because not many people are daft enough like myself to do this kind of mistake).
@ALL Anyways sorry I meant to mark this as solved a little earlier and forgot
Thanks for all the help everyone's gave (and still thanks for those who's tried)
