In the editor, there is no subscreen with magic bar, butt I have seen 2.10 quests using the magic bar. Where do I get a magic bar, if possible separated to show magic containers?
Subscreen With Magic Bar
First you have to have the appropriate rule checked, I think it's something like "Allow Magic". Then you want to check similar rules stating which items use magic. Then the default subscreen "Passive (Magic)" should have a magic bar already drawn, depending on what subscreen type you're using.
There are only three subscreens and no one offers the magic option. All rules concerning magic are active, otherwise the enemies wouldn't drop magic jars.
Mine comes with a default of 4, active dungeon, active triforce, passive magic, passive no magic. Are you using the original Zelda tileset?
Yes, I am. And I am using Zelda 2.10 editor.
My guess is that it doesn't have a magic bar drawn, you'll need to draw it yourself and make a subscreen with it in it. And from what I remember, 2.10 doesn't have a subscreen editor. It's been a while since I used 2.10 though...
