I see, well, i will edit the article after posting this, consider it done in about a minute, and i was thinking at first that this would be a waste of time to implement because you can just do it fromt he drop item menu, but then i reconsidered and thought it would be effective in a global link script, where you can have:
IF $CHAPTERID = 4 THEN
$ITEMSTATE02 := 0
So lets say Chapter 4 is a prison, it drops your "knife" for example, since you cant bring a knife into a prison...
Anyways, yeah, those are my thoughts, and i will get to your article now!
