Allow menu during events - for Visual Novels - Taylor - 08-25-2011

In truth, I don't have a plan to release this system public on the basis I don't trust it to be stable. However I am showing it because I would like any pointers as to improvements on how to better handle what I have.

This script allows the menu to be opened during events. Due to the way events are handled in XP, this isn't quite straight-forward. This script backs up events to where they were after the menu was opened (important for re-reading messages), and makes sure to skip the "mid-command" lines RMXP seems to have (things like Show Choice are actually interpreted in multiple lines, not as a single command).

The last point is specifically something I want to watch out for. I have an array there of every command index that leads to an actual command, but I cannot say for certain that this is the most apt way to handle it?

Oh brill, that's handy, very handy. Thanks for sharing!

RE: Allow menu during events - for Visual Novels - Taylor - 08-25-2011

Minor update to avoid an error if you open the menu before any events happened. ... which wouldn't show up in a demo I'd imagine, but better safe than sorry 'case it affected other things.
