self.z? [solved]

[diagostimo]

hi, i was wondering if anyone knows how i can change the self.z of a picture shown in a window, so it is behind my index's cursor_rect, or the other way around so the the self.z of the cursor is higher than the picture, heres my script for reference:

if anyone knows how i can accomplish this, i will be in your gratitude

That really wouldn't be possible with a complete rewrite of the Window class. Which is a hidden class. With the way windows are setup, there really is no "z" value for the contents getting drawn. You have to choose the order yourself. But there are parts you can't control, like the cursor. The drawing order occurs like this, Background -> Border -> Cursor/Arrows -> Your Content. The only way to change this is to either create your own rewrite of the class.

im guessing this is written in C++ for the exe right?

[ForeverZer0]

I think its just C.

Doesn't really make a difference in regards to your question.
Just set the opacity of the window background to 0, and set a picture behind it. It will have the same effect.

[diagostimo]

im unsure where i would set the opacity :/

[G_G]

In the window initialization.

self.back_opacity = 0

cool, iv looked at how another script set a background image, and i believe i am to use this line: @sprite.bitmap = RPG::Cache.picture("") in main, but i get no image drawn, do i need to define it anywhere else?

[G_G]

Can't just have empty quotes. You need to actually choose a file to load.

class Scene_Alias
  def main
    @sprite = Sprite.new
    @sprite.bitmap = RPG::Cache.picture("picture name")
    Graphics.transition
    loop do
      Graphics.update
      Input.update
      update
      if $scene != self
        break
      end
    end
    @sprite.dispose
  end
end

i did realise that, i was just using it as a reference, but i did forget the @sprite = Sprite.new and @sprite.dispose, thanks for your help

[G_G]

Glad I could be of some help. :3

[diagostimo]

i have just realised that the windows border is still showing, can i change the opacity of this to 0?

[ForeverZer0]

Just use @window.opacity instead of @window.back_opacity.

cool, thanks bro
