He's a good guy, make sure you mention how much you like his scripts better than Seph's
LOL!
Alright, it's rather easy to make a cross call. Find these lines:
when 0
$game_system.se_play($data_system.decision_se)
make_items
@command_window.active = false
@item_choose_window.active = true
@help_window.x = 0
@help_window.y = - 576
@help_window.set_text("")
@items_window1.visible = true
@items_window2.visible = true
@help_window.visible = false
@help_window.update
items_refresh
As far as I see how the Diablo inventory works, you could make it easily work by just changing those lines to:
when 0
$game_system.se_play($data_system.decision_se)
$scene = Scene_Item2.new
Graphics.transition(0)
The inventory should call the Menu back by itself.
