Obvious problem is that you can't use Scene_Equip directly. That $scene global variable is a finicky thing to work with. The idea behind scenes, at least in the way Enterbrain designed them, is that they assume you are done with the previous scene and no longer need it. Everything gets disposed and all the little switches and variables that the previous scene stored are now gone. So even if you were able to get to Scene_Equip and go back to Scene_Battle...you'd be right back at the start of a new fight.
The best way to handle this situation is to make Scene_Equip, well, scene-less. Like so
class Sceneless_Equip
#--------------------------------------------------------------------------
# * Object Initialization
# actor_index : actor index
# equip_index : equipment index

@actor = $game_actors[@actor_index]

@help_window = Window_Help.new
@left_window = Window_EquipLeft.new(@actor)

@item_window1 = Window_EquipItem.new(@actor, 0)
@item_window2 = Window_EquipItem.new(@actor, 1)
@item_window3 = Window_EquipItem.new(@actor, 2)
@item_window4 = Window_EquipItem.new(@actor, 3)
@item_window5 = Window_EquipItem.new(@actor, 4)
# Associate help window
@right_window.help_window = @help_window
@item_window1.help_window = @help_window

@item_window.refresh
return

end
end
And you call it up like so from Scene_Battle
s = Sceneless_Equip.new(@active_battler.id)
s.main
The only change is that I got rid of the pesky
$scene != self to signify when we are done. Instead, this is handled with a single boolean
@abort, which gets turned to true when the B button is pressed. I also got rid of the L and R buttons to toggle between the different actors. Everything else is still the same.
Using the snippet you provided of your Scene_Battle 3, this is what I would do:
when 2 # equip
$game_system.se_play($data_system.decision_se)
Graphics.freeze
@status_window.visible = false
@actor_command_window.visible = false
@spriteset.toggle_viewports
s = Sceneless_Equip.new(@active_battler.id)
s.main
@spriteset.toggle_viewports
@status_window.visible = true
@actor_command_window.visible = true
Graphics.transition
And here's the
toggle_viewports method.
class Spriteset_Battle
def toggle_viewports
@viewport1.visible = @viewport2.visible =
@viewport3.visible = @viewport4.visible = !@viewport1.visible
end
end
We first freeze the graphics so that we can make a smooth transition to our equipment scene. We then hide the windows and viewports since they stick up through the equipment windows (go ahead and remove those lines to see for yourself). Then we call our equip "scene" and its update loop
main. It stays at this point until we abort the equip, which it will then bring back the windows and viewports we hid earlier, and makes the Graphics transition to smooth ourselves back into battle.
