[Resolved] Fog Priority Layers?

Latest Post

Basically, i was wondering if it is possible to create a fog script somehow so that any tiles with a priority of 5 or something are drawn above the fog. while all tiles without the priority of 5 are affected by the fog.

Here's the default screen of when you add a fog:

Here's a mock-up of what i'm trying to do (the fog is still on the level, but not on the roof):

Any suggestions or existing scripts etc.?

Thanks for the help in advance,
RM

well yes in a sense, basically anything with a priority of 5 (as an example) would be "unfogged".

I've been attempting to script it myself for the past few days but am unfamiliar with RGSS, just know Turing and a bit of Java at the moment. Any help would be greatly appreciated.

This is a bit tricky because of the way the Tilemap is created. Each tile truthfully has it's own z dimension. The fog by default is set at 3000, way above your Tilemap.

I do have an idea however, that will create an additional tilemap (well, just a sprite), and put it on top of the fog when a tile has a certain terrain tag. This should cover it up.

Give me a few minutes to see what I can't come up with...

No more doing that. Here you go:

Code: 
class Sprite_FogCover < Sprite
  attr_accessor :tileset_filename
  attr_accessor :autotiles
  attr_accessor :autotiles_name
  attr_accessor :terrain_tags
  attr_accessor :priorities
  attr_reader :map_data
  def initialize(viewport = nil)
    super(viewport)
    @refresh_data = nil
    @autotiles_name = []
  end
  def map_data=(map_data)
    @map_data = map_data
    if self.bitmap != nil
      self.bitmap.dispose
    end
    self.bitmap = Bitmap.new(@map_data.xsize * 32, @map_data.ysize * 32)
    refresh
  end
  def refresh
    @refresh_data = @map_data
    for z in 0...@map_data.zsize
      for x in 0...@map_data.xsize
        for y in 0...@map_data.ysize
          id = @map_data[x, y, z]
          next if id == 0
          next if terrain_tag(x, y) != 7
          id < 384 ? draw_autotile(x, y, id) : draw_tile(x, y, id)
        end
      end
    end  
  end

    bit = RPG::Cache.tile(@tileset_name, id)
    self.bitmap.blt(x * 32, y * 32, bit, Rect.new(0, 0, 32, 32))
  end

    filename = @autotiles_name[tile_id / 48 - 1]
    bit = RPG::Cache.autotile_tile(filename, tile_id % 48)
    self.bitmap.blt(x * 32, y * 32, bit, Rect.new(0, 0, 32, 32))
  end
  def update
    if @refresh_data != @map_data || Graphics.frame_count % 16 == 0
      refresh

Note: I took it from a demo with the MACL, so if an undefined method error occurs, let me know. I may have forgot to carryover something.

By default, the terrain tag is 7 to be drawn over the fog.

Enjoy! ^_^

I got another error :( I feel bad reporting them because I didn't even request it but here goes.  I think I may have noticed 2 things.

1 I'm not sure this includes autotiles because  I tried a plain room just with a ceiling autotile and the game loaded fine but the fog was same as ever.  I then assumed that this didn't support autotiles so tried a normal tile.

2 And got a wrong number of arguments on line 35 (2 of 3)

Sorry for the bad news man, this is a really cool fix though.

EDIT: No I see in the script that it may be that normal tiles are the part not supported.  I'll try and make it work again.

EDIT 2: I get that error with autotiles too.

Hey, that script is pretty good actually. Thanks for the help Seph!

However, i noticed the same problem as Calibre with the normal tiles: wrong number of arguments on line 35 (2 of 3)
Autotiles seem to work pretty great though.

Well just for reference, I definately get a script error on new game.  On line 35.  That is for both autotiles and normal tiles.  This was also definately in a new project.  It's not like I have anything I can visually show you in a demo.  I can upload the error screen if you wish but its definately on line 35 wrong number of arguments. 

To set it up, all i did was make a map on any interior, put just the ceiling autotile to terrain tag 7, added the fog to the tileset within the database (just for ease) and pressed new game but got the error.

That's it man, you've got it.  You should make a thread of all your little scripts (if you haven't) save them going unnoticed.  This is a big help for mapping certain places if you're a fog whore.

Wow, yep that works perfectly. Thank you Seph, you helped me quite a bit with this little script.
I wouldn't call myself a fog whore lol, but i am a fan of using fogs in caves since most caves (in real-life) are quite dull with not much too much to see/do. This will definetely bring some extra life to my maps. Thank you again.

Btw, what are permission/credit usage of this script?

Hehe. Glad you guys like it.

I am saving most of them. I just try to do 3-5 of these little request of a day, so its hard to keep track of them.

Feel free to use it as you wish, just be sure to credit you. And you will find an update in my best bed v.5, whenever I get to that.

Lol. That's what I get for multi-tasking. I was trying to remind myself to credit both of you when I go to tidy up the script and add it to that hunk-o-junk I call a test bed, and just typed a clusterfuck. XD

Yeah, credit me and you two for your help with debugging. :p
