What do you mean by key items in 'try using key items for important event markers, and use those instead of switches' ?
Hmmz, do you mean that a variable can be used for more than one event ?
If let's say switch001 changes a character to say something different after I do a quest or something similar, how do you switch off switch001 without affecting what the character says after the quest ? If I switch off, the character will say the same thing before the quest right ?
ermz.. Ehz.. Sorry lehz, so many questions!! but would really like to know
